How Sonar Works

Sonar technology is based on sound waves. The 300 Series™ Fishing System uses sonar

to locate and define structure, bottom contour and composition, as well as depth

directly below the transducer.

Your 300 Series™ Fishing System sends a sound wave signal and determines distance by

measuring the time between the transmission of the sound wave and when the sound

wave is reflected off of an object; it then uses the reflected signal to interpret location,

size, and composition of an object.

Sonar is very fast. A sound wave can travel from the surface to a depth of 240 ft

(70 m) and back again in less than 1/4 of a second. It is unlikely that your boat can

"outrun" this sonar signal.

SONAR is an acronym for SOund and NAvigation

Ranging. Sonar utilizes precision sound pulses or

"pings" which are emitted into the water in a teardrop-

shaped beam.

The sound pulses "echo" back from objects in the water

such as the bottom, fish and other submerged objects.

The returned echoes are displayed on the LCD screen.

Each time a new echo is received, the old echoes are

moved across the LCD, creating a scrolling effect.

When all the echoes are viewed side by side, an easy to

interpret "graph" of the bottom, fish and structure

appears.

Download from Www.Somanuals.com. All Manuals Search And Download.

The sound pulses are transmitted at various frequencies

depending on the application. Very high frequencies

(455 kHz) are used for greatest definition but the

operating depth is limited. High frequencies (200 kHz)

are commonly used on consumer sonar and provide a

good balance between depth performance and

resolution. Low frequencies (83 kHz) are typically used

to achieve greater depth capability.

The power output is the amount of energy generated

by the sonar transmitter. It is commonly measured

using two methods:

• Root Mean Square (RMS) measures power

output over the entire transmit cycle.

• Peak to Peak measures power output at the

highest points.

The benefits of increased power output are the

ability to detect smaller targets at greater distances,

ability to overcome noise, better high speed

performance and enhanced depth capability.

DualBeam PLUS™ Sonar

Your 300 Series™ Fishing System uses a 200/83 kHz

DualBeam PLUS™ sonar system with a wide (60°) area of

coverage. DualBeam PLUS™ sonar has a narrowly

focused 20° center beam, surrounded by a second beam

of 60°, expanding your coverage to an area equal to your

depth. In 20 feet of water, the wider beam covers an area

20 feet wide. The 20° center beam is focused on the

bottom, to show you structure, weeds and cover. The

60° wide beam is hunting for fish in the wide coverage

area. DualBeam PLUS™ sonar returns can be blended

together, viewed separately or compared side-by-side.

DualBeam PLUS™ is ideal for a wide range of conditions -

from shallow to very deep water in both fresh and salt

water. Depth capability is affected by such factors as boat

speed, wave action, bottom hardness, water conditions

and transducer installation.

How GPS and Cartography Work

Your 300 Series™ Fishing System also supports GPS and chartplotting, and uses GPS and

sonar to determine your position, display it on a grid, and provide detailed underwater

information. The Global Positioning System (GPS) is a satellite navigation system

designed and maintained by the U.S. Department of Defense. GPS was originally

intended for military use; however, civilians may also take advantage of its highly

accurate position capabilities, typically within +/- 10 meters, depending on conditions.

This means that 95% of the time, the GPS receiver will read a location within 10 meters

of your actual position. Your GPS Receiver also uses information from WAAS (the Wide

Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay

Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are

available in your area.

Download from Www.Somanuals.com. All Manuals Search And Download.

GPS uses a constellation of 24 satellites that continually

send radio signals to the earth. Your present position is

determined by receiving signals from up to 16 satellites

and measuring the distance from the satellites.

All satellites broadcast a uniquely coded signal once per

second at exactly the same time. The GPS receiver on

your boat receives signals from satellites that are visible

to it. Based on time differences between each received

signal, the GPS receiver determines its distance to each

satellite. With distances known, the GPS receiver

mathematically triangulates its own position. With

once per second updates, the GPS receiver then

calculates its velocity and bearing.

The GPS Receiver included with your 300 Series™ Fishing System, allows you to combine

easy-to-use FishingGPS™ chartplotter and navigation capabilities with advanced

fishfinding. The following GPS functionality is currently supported by the 300 Series™

Fishing System:

• View current position

• View current track (breadcrumb trail)

• View precision speed and heading from your GPS receiver

• Save tracks, waypoints and routes

• Travel a route and navigate from one waypoint to the next.

Your unit also comes with a built-in UniMap™ with a more detailed map of North

America (Domestic models) or a more detailed map of Europe and Southeast Asia,

including Australia and New Zealand (International models).

Your 300 Series™ uses the GPS Receiver to determine the position of the boat

automatically, and uses the zoom level settings on a particular view to select the best

chart to display. See Viewing Cartography for more information.

What’s On the Display

The 300 Series™ Fishing System can display a variety of useful information about the area

Depth - water depth; can be set to alarm when

the water becomes too shallow.

Cursor - available in Freeze Frame and can be

positioned in the Sonar View to provide depth of a

sonar return and bottom depth below the cursor.

Temperature - water surface temperature.

Timer

Elapsed time with Temp/Speed

Accessory or GPS Receiver.

Distance - Distance traveled with Temp/Speed

Accessory or GPS Receiver.

Average Speed - Average speed reading with

Temp/Speed Accessory or GPS Receiver.

Speed - if a Temp/Speed accessory or GPS

Receiver is attached, the FishFinder can display

the speed of the boat, and can keep a Triplog of

nautical or statute miles traveled.

Second Sonar Return - when the sonar signal

bounces between the bottom and the surface of the

water and back again. Use the appearance of the

second return to determine bottom hardness. Hard

bottoms will show a strong second return, while soft

bottoms will show a very weak one or none at all.

Cursor Dialog Box - indicates cursor depth on the

display and the depth of the bottom directly below

the cursor. The Latitude and Longitude of the cursor

position, the distance to travel to the cursor position

and the bearing to the cursor position is shown with a

GPS receiver. A waypoint can be marked at the cursor

position for later retrieval and use with a GPS receiver.

NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either

only the information from the GPS receiver will be displayed on the view.

Sonar View

Sonar View presents a historical log of sonar returns. Depth is always displayed.

Readouts for temperature and speed are automatically displayed if the appropriate

accessory is connected. The most recent sonar returns are charted on the right side of

the window; as new information is received, the older information is moved across the

display to the left. A Digital Depth Readout is displayed in the upper left corner. A scale

with Upper and Lower Depth Range readouts appears along the right edge of the Sonar

View. The scale indicates the distance from the surface of the water to a depth range

sufficient to show the bottom. Depth Range is automatically selected to keep the

bottom visible on the display, although you can adjust it manually as well (see Sonar

X-Press™ Menu). Five additional Digital Readouts display information from optional-

purchase accessories. These information boxes can be customized to show only the

information desired (see Setup Menu Tab, Select Readouts).

Understanding Sonar History

It is important to understand the significance of the

300 Series™ Fishing System display. The display does

NOT show a literal 3-dimensional representation of

what is under the water. Each vertical band of data

received by the control head and plotted on the

display represents something that was detected by a

sonar return at a particular time. As both the boat and

the targets (fish) may be moving, the returns are only

showing a particular segment of time when objects

were detected, not exactly where those objects are in

relation to other objects shown on the display.

Real Time Sonar (RTS®) Window

A Real Time Sonar (RTS®) Window appears on the right side of the display in the Sonar

View only. The RTS® Window always updates at the fastest rate possible for depth

conditions and shows only the returns from the bottom, structure and fish that are

within the transducer beam. The RTS® Window plots the depth and intensity of a sonar

return. (See Sonar Menu: RTS® Window) .

The Narrow RTS® Window

indicates the sonar intensity

through the use of colors.

The Wide RTS® Window

indicates the sonar intensity

through the use of a bar

graph. The length of the

plotted return provides an

indication of whether the

return is weak or strong. The

depth of the sonar return is

indicated by the vertical

placement of the return on

the display depth scale.

Red indicates

strong

return and blue indicates a

weak return. The depth of

the sonar return is indicated

by the vertical placement of

the return on the display

depth scale.

Freeze Frame

Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen

and a cursor will be displayed on the screen. The cursor can be positioned on the display

using the 4-WAY Cursor Control key to determine the depth of any sonar return. The

RTS® Window continues to update in Freeze Frame. In addition, see the effects of menu

setting changes with Instant Image Update. Pressing EXIT will exit Freeze Frame and the

display will start to scroll. Freeze Frame is available in the Sonar, Sonar Zoom, and

200/83 kHz Split Sonar Views.

Bottom Presentation

As the boat moves, the unit charts the changes in depth on the display to create a profile

of the Bottom Contour. The type of bottom can be determined from the return charted

on the display. A Hard Bottom such as compacted sediment or flat rock appears as a

thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker

line across the display. Rocky Bottoms have a broken, random appearance.

Bottom Contour Profile with RTS® Window.

Temp/Speed Accessory is optional.

The sonar returns from the bottom, structure and fish can be represented as either

WhiteLine® or Structure ID®. See Sonar Menu Tab: Bottom View for details on how to

set the bottom view.

Structure ID® represents weak returns in blue and

strong returns in red.

WhiteLine® highlights the strongest sonar returns in

white, resulting in a distinctive outline. This has the

benefit of clearly defining the bottom on the display.

Sonar Zoom View

Sonar Zoom View increases the displayed resolution to separate sonar returns that are

very close together, such as those caused by fish suspended close to the bottom or

within structure. In Zoom View, the display is split to show a narrow slice of the full

range view on the right and the zoomed view on the left. The full range view on the right

also contains the Zoom Preview Box that shows what part of the full range view is

shown in zoom view on the left; the Zoom Preview Box tracks the bottom in the full

range view.

As the depth changes, the zoomed view updates automatically to display a magnified

image of the bottom. The Zoom Preview Box shows where the zoomed view is in

relation to the full range view. The Zoom Level, or magnification, is displayed in the

lower left corner and can be changed to suit conditions (see Sonar X-Press™ Menu: Zoom

Level). Upper and Lower Zoom Depth Range numbers indicate the depth of the water

which is being viewed.

Digital depth is displayed in the upper left hand corner. The digital readouts in the Sonar

Zoom View cannot be customized; therefore, information such as water temperature

and voltage are unavailable in the Sonar Zoom View.

In the Chart or Combo Views there are several cartography-related functions that you

can access using various keys.

Panning: Use the 4-WAY Cursor keys to move the

chart around on the display in the direction of the key

being pressed. When you do this, a bull's eye cursor

is drawn at the center of the screen and is linked to

the boat by a gray line, even if the boat is off the

screen. At the same time, the temperature and speed

boxes in the lower left corner are replaced with the

distance and bearing from the boat to the cursor

position and the latitude/longitude coordinates of

the cursor.

Chart View with Cursor Present

Zooming: Use the Plus (+) key to Zoom In and the Minus (-) key to Zoom Out showing

the cartography at different scales. The scale is indicated on the left side of the display.

If you zoom in beyond the available chart data, the display will go into Overzoom mode

whereby the last available chart data is amplified to reflect the scale selected. If you

zoom in so far that no cartography is available, a lat/long grid will be drawn instead.

Chart Info: Use the INFO key to get detailed information about the chart. If the cursor is

active, you will see information about the chart objects located near the cursor.

Introduction to Navigation

Download from Www.Somanuals.com. All Manuals Search And Download.

Simulator

Use the Simulator to learn how to use your 300

Series™ Fishing System before taking your boat on

the water. The Simulator is a very powerful tool that

simulates on the water operation, providing a

randomly-updated display. We recommend going

through this manual while using the Simulator, since

all of the menus function and affect the display the

way they actually do when in Normal operation.

Simulator

NOTE: To get the full benefit of the Simulator, it is important to select Simulator manually

from the Start-Up Options menu as opposed to letting the 300 Series™ Fishing System enter

Simulator automatically (as it will if a transducer is not connected and you do nothing during

power up). Manually selecting Simulator from the Start-Up Options menu allows you to pre-

configure your 300 Series™ Fishing System for on the water operation. Any menu changes you

make will be saved for later use.

A message will appear on the display periodically to remind you that you are using the

Simulator.

Exit the Simulator by powering your 300 Series™ Fishing System off.

Sonar X-Press^TMMenu

Download from Www.Somanuals.com. All Manuals Search And Download.

Sensitivity

Sensitivity controls how much detail is shown on the

display and will adjust the sensitivity of all sonar frequencies. Increasing the sensitivity

shows more sonar returns from small baitfish and suspended debris in the water;

however, the display may become too cluttered. When operating in very clear water or

greater depths, increased sensitivity shows weaker returns that may be of interest.

Decreasing the sensitivity eliminates the clutter from the display that is sometimes

present in murky or muddy water. If Sensitivity is adjusted too low, the display may not

show many sonar returns that could be fish.

NOTE: The Sensitivity setting is a global setting and will adjust the sensitivity of all sonar

frequencies, as compared to specific sensitivity adjustments (such as 83 kHz Sensitivity) that

allow you to adjust the level of sensitivity for one specific beam at a time.

Sensitivity at Low

Sensitivity at Medium

Sensitivity at High

To adjust the Sensitivity:

1. Highlight Sensitivity on the Sonar X-Press^TMmenu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the

Sensitivity setting. (Low = 1, High = 20, Default = 10)

_{Download from Www.Somanuals.co}3_m6_{. All Manuals Search And Download.}

Upper Range

(Advanced: Sonar, Split Sonar, Big Digits and

Circular Flasher views only)

Upper Range sets the shallowest depth range that will be displayed on the Sonar, Split

Sonar, Big Digits and Circular Flasher Views. The Upper Range menu choice is available

when User Mode is set to Advanced (see Setup Menu Tab: User Mode) and can only be

accessed from the Sonar, Split Sonar, Big Digits and Circular Flasher Views. Upper Range

is often used with Lower Range.

For example, if you are only interested in the area between 20 and 50

feet deep, you should set the Upper Depth Range to 20 and the Lower

Depth Range to 50. The Sonar View will then show the 30 foot area

between 20 and 50, and will not show the surface or the bottom

(assuming the bottom is deeper than 50 feet), and will show greater

detail for that area between 20 and 50 feet.

NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower

Range regardless of the manual settings entered.

To adjust the Upper Range:

1. Make sure you are in Advanced Mode, then highlight Upper Range on the Sonar

X-Press^TMmenu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the

Upper Range setting. (0 to 990 feet or 0 to 327 meters [International Models

only], Default = 0)

Download from Www.Somanuals.com. All Manuals Search And Download.

Lower Range

Lower Range sets the deepest depth range that will be

displayed. Automatic is the default setting. When in automatic mode, the lower range will be

adjusted by the unit to follow the bottom. Selecting a specific setting locks the depth range

into Manual mode. Use both Upper and Lower Range together to view a specific depth range

manually when looking for fish or bottom structure.

corner of the screen when you start manually adjusting the Lower Range to indicate that you

are in Manual mode.

will be displayed in the lower right

For example, if you are fishing in 60 feet of water but are only

interested in the first 30 feet (surface to a depth of 30 feet) you should

set the Lower Depth Range limit to 30. The display will show the 0 to

30 foot range, allowing you to see a more detailed view than you

would see if the display went all the way to the bottom.

NOTE: A minimum distance of 10 feet will be maintained between the Upper and Lower

Range regardless of the manual settings entered.

To adjust the Lower Range:

1. Highlight Lower Range on the Sonar X-Press^TMmenu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the

Lower Range setting. (AUTO, 10 to 1000 feet, 3 to 330 meters [International

Models only], Default = AUTO)

_{Download from Www.Somanuals.co}3_m8_{. All Manuals Search And Download.}

Chart Speed

Chart Speed determines the speed at which the sonar

information moves across the display, and consequently the amount of detail shown. A

faster speed shows more information in the Sonar Views and is preferred by most

anglers; however, the sonar information moves across the display quickly. A slower

speed keeps the information on the display longer, but the bottom and fish details

become compressed and may be difficult to interpret. Regardless of the Chart Speed

setting, the RTS® Window will update at the maximum rate possible for the depth

conditions. Adjust Chart Speed to your personal preference.

To adjust the Chart Speed:

1. Highlight Chart Speed on the Sonar X-Press™ menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or decrease the Chart

Speed setting. (1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra = Fastest, Default = 5)

Bottom Range

(Sonar Zoom view only when Bottom Lock is On)

Bottom Range allows you to control how much of the water column, measured up from

the bottom, is shown in the Sonar Zoom View. Choose a small value to see low-lying

bottom structure or details of the bottom return. Choose a larger value to see large

structure in deeper water. It is possible to set the Bottom Range to be greater than the

depth. In this case, you may see surface clutter in a wavy band that mirrors changes in

the depth.

To adjust the Bottom Range:

1. In the Sonar Zoom View, highlight Bottom Range on the Sonar X-Press™ menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom

Range setting. (10 - 60 feet or 3-20 meters [International Models only],

Default = 15 feet)

_{Download from Www.Somanuals.co}3_m9_{. All Manuals Search And Download.}

Bottom Lock

(Sonar Zoom view only)

Bottom Lock changes the mode of the Zoomed view in the Sonar Zoom View. Bottom

Lock continuously graphs the bottom at a constant point on the display regardless of

changes in depth. This "flattens" out the bottom contour, but is effective at showing fish

on or near the bottom.

To turn on Bottom Lock:

1. In the Sonar Zoom View, highlight Bottom Lock on the Sonar X-Press™ Menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Bottom Lock

setting to on. (Off, On, Default = Off)

Fish ID+^TM

Fish ID+^TMuses advanced signal processing to interpret

sonar returns, and will display a Fish Symbol when very selective requirements are met. When

a fish is detected, a fish icon and its depth are displayed above the return that has been

classified as being a fish. Three different fish size icons represent the intensity of the sonar

return, and provide an indicator of relative fish size.

DualBeam PLUS^TMsonar models represent targets detected in the 200 kHz narrow beam as Orange

Fish Symbols, and represent targets detected in the 83 kHz wide beam as Blue Fish Symbols.

200 kHz, Narrow Beam

Orange Fish Symbols

83 kHz, Wide Beam

Blue Fish Symbols

When Fish ID+^TMis turned off, the 300 Series™ Fishing System shows only the raw sonar returns

on the display. These returns will often result in "arches" forming on the display, indicating

potential targets. Due to the transducer beam angle, the distance to a fish decreases as the fish

moves into the beam, and then increases as it moves out again, creating a Fish Arch when this

distance change is shown on the display. Boat speed, chart speed, and the position of the fish

within the sonar beam greatly affect the shape of the arch.

Transducer Cone and Fish Arches

To turn Fish ID+™ on or off:

1. Highlight Fish ID+ on the Sonar main menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to turn the Fish ID+^TMsetting

Fish ID Sensitivity

Fish ID Sensitivity adjusts the threshold of the

Fish ID+^TMdetection algorithms. Selecting a higher setting allows weaker returns to

be displayed as fish. This is useful for identifying smaller fish species or baitfish.

Selecting a lower setting displays fewer fish from weak sonar returns. This is helpful

when seeking larger species of fish. Fish ID Sensitivity is used in conjunction with

Fish ID+^TM. Fish ID+^TMmust be On for Fish ID Sensitivity to affect the ability of the

300 Series™ Fishing System to identify sonar returns as fish.

To change the Fish ID Sensitivity setting:

1. Highlight Fish ID Sensitivity on the Sonar main menu.

2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to change the Fish ID

Troubleshooting

Before contacting the Humminbird® Customer Resource Center, please read the

following section. Taking the time to review these troubleshooting guidelines may allow

you to solve a performance problem yourself, and therefore avoid sending your unit

back for repair.

300 Series™ Doesn’t Power Up

If your 300 Series™ Fishing System doesn’t power up, use the Installation Guide that also

comes with it for specific confirmation details, making sure that:

• The power cable is properly connected to the 300 Series™ Fishing System

control head.

• The power cable is wired correctly, with red to positive battery terminal and

black to negative terminal or ground.

• The fuse is operational.

• The battery voltage of the power connector is at least 10 Volts.

Correct any known problems, including removing corrosion from the battery terminals

or wiring, or actually replacing the battery if necessary.

300 Series™ Defaults to Simulator with a Transducer Attached

A connected and functioning transducer will cause the newly-started 300 Series™

Fishing System to go into Normal operating mode automatically. If, when you power up

the 300 Series™ Fishing System, it goes into Simulator mode automatically, even though

a transducer is already connected, this means that the control head is not detecting the

transducer. Perform the following troubleshooting tasks:

• Using the Installation Guide that also comes with your 300 Series™ Fishing

System, check to make sure that the transducer cable is securely connected to

the 300 Series™ Fishing System. Reconnect if necessary, and power up the 300

Series™ Fishing System again to see if this fixes the problem.

• Replace the non-functioning transducer with a known good transducer if

available and power up the control head again.

• Check the transducer cable. Replace the transducer if the cable is damaged

or corroded.

Display Problems

There are several main conditions or sources of possible interference that may cause

problems with the quality of the information displayed on the control head. Look in the

following table for some symptoms of display problems and possible solutions:

Problem

Possible Cause

The control head loses

power at high speeds.

If the power output of your boat’s engine is

unregulated, the control head may be protecting

itself using its over-voltage protection feature.

Make sure the input voltage does not exceed 20

Volts.

When the boat moves at

higher speeds, the bottom

disappears or suddenly

weakens, or the display

contains gaps.

The transducer position may need to be adjusted.

A mix of air and water flowing around the

transducer (cavitation) may be interfering with

the interpretation of sonar data. See your

Installation Guide for suggestions on adjusting

the transducer position.

Electrical noise from the boat’s engine may be

interfering with sonar reception. See Finding the

Cause of Noise for more information.

Sonar readings may be affected if the transducer is

not positioned correctly (i.e. mounted at an angle,

not straight down), or there is some kind of

mechanical interference, either because it is

mounted inside a hull that is too thick for proper

sonar transmission, the bond between the

transducer and the hull is not airtight, or because

the transducer is dirty. Check with your Installation

Guide for guidance on re-positioning the

transducer, and make sure the transducer is clean.

There are no fish detected,

even when you know they

are in the water under the

boat, or sonar readings

seem weak or faulty.

Low battery voltage may be affecting the power of

signal transmission.

Electrical noise from the boat’s engine may be

interfering with sonar reception. See Finding the

Cause of Noise for more information.

_{Download from Www.Somanuals.co}8_m8_{. All Manuals Search And Download.}

Finding the Cause of Noise

Electrical noise usually affects the display with many black dots at high speeds, and high

sensitivity readings. One or more of the following sources can cause noise or

interference:

Possible Source of Noise

Other electronic devices

Isolation

Turn off any nearby electronic devices to see if the

problem goes away, then turn them on one at a

time to see if the noise re-appears.

The boat’s engine

To determine whether the boat’s engine is the

source of the noise, increase the RPMs while the

boat is in neutral and stationary to see if the noise

increases proportionately; if noise appears when

you rev the engine, the problem could be the spark

plugs, alternator, or tachometer wiring. Replace the

spark plugs with resistor plugs, install an alternator

filter, or route the control head power and

transducer cables away from the engine wiring.

Turbulence created by the propeller can cause

noise; make sure the transducer is mounted at least

15” (38 cm) from the propeller, and that the water

flows smoothly over the face of the transducer at all

times.

Cavitation from the boat’s

propeller

Glossary

Sonar Terms:

Alarm, Depth: Depth Alarm is a user-controllable, audible alert that sounds when depth

is less than or equal to the setting.

Alarm, Temperature: Temperature Alarm is a user-controllable, audible alert that

sounds when the water surface temperature equals the setting.

Backlight: Backlight is a user-controllable illumination for the LCD for night and low

light use.

Beam (Sonar Beam): A sonar beam is the wide, cone-shaped projection of sound waves

formed as sound travels underwater. See Cone Angle.

Big Digits View: Big Digits View is a Humminbird® feature that displays the sonar graph

and enlarged digital readouts for easy reading from a distance. This is a great tool when

monitoring the digital depth is important - such as with higher boat speeds, or when

viewing the unit from a distance. When speed input is available, the Big Digits View also

shows the TripLog. See TripLog.

Bottom Black: Bottom Black is a Humminbird® feature that "fills in" the area of the

display below the bottom contour. Bottom Black is preferred by some anglers because of

its high contrast and easy readability, even though it can obscure bottom hardness

information.

Bottom Contour: Bottom Contour is the profile of the bottom graphed to the display as

the depth changes.

Bottom Hardness: Bottom Hardness is the density (or composition) of the bottom,

which can often be determined by interpreting the main sonar return. Varying levels

of hardness can be determined by interpreting the "thickness" of the sonar return.

Hard returns appear thin and black, softer returns appear thicker and less black. It is

important to note that a sonar return from a sloping bottom can have the

appearance of a softer bottom.

Cavitation: Cavitation is the effect of air bubbles created as the propeller rotates and the

boat moves through the water.

Chart Speed: Chart Speed is a user-controllable feature that sets the speed at which

sonar information moves across the display. A faster setting displays sonar information

from more pings and shows more detail, but the information moves quickly across the

display: a slower setting permits viewing of more sonar history, but does not display as

much detail. The best setting is often the user's personal choice.

Cone Angle: The cone angle is the angular measurement of the sonar beam at a specific

dB down point (i.e. -10 dB). See dB Down Point.

Customizable Digital Readouts: Customizable Digital Readouts is a Humminbird®

feature that permits the user to select the specific digital information that appears in

the main Sonar view (i.e. Speed, Temperature, Barometric Pressure, TripLog, etc.)

Dead Zone: The dead zone is the area of the sonar beam that receives the sonar signal

after the main bottom return. Fish and other objects close to the bottom that fall within

the dead zone will probably not be visible in the sonar beam. Precision sonar beams,

such as the Humminbird® 20° beam, have a smaller dead zone than wider sonar beams.

Decibel: A Decibel is the measurement for sound pressure level, or "intensity" of the

sonar return. See dB Down Point.

dB Down Point: The dB Down Point is the standard decibel level at which the sonar cone

angle is measured, and is written as "@ -10 dB" or "@ -3 dB". Measurements at smaller

down points (bigger negative numbers) indicate that the less intensive sonar signals are

being used for the measurement.

Display, FSTN: FSTN is an acronym for Film Super-Twist Nematic. FSTN is a monochrome

display technology characterized by black, high-contrast pixels. All monochrome fixed

mount Humminbird® products use FSTN technology.

DualBeam PLUS™: DualBeam PLUS™ is a Humminbird® sonar configuration that uses

two sonar beams simultaneously, and combines the information from both beams into

one view by overlapping the data on-screen, or shows each beam individually side by

side, or permits each beam to be viewed individually full screen.

Feature Memory: Feature Memory is a Humminbird® feature that retains the user's

menu settings in permanent memory. Settings are retained even when the unit is

powered off indefinitely.

_{Download from Www.Somanuals.co}9_m2_{. All Manuals Search And Download.}

Fish Arch: A Fish Arch is the apparent "arch" that appears on the display when any object

moves through the sonar cone. The arch results from a gradual decrease in distance to

an object as it moves into the sonar cone. The distance to an object changes due to the

conical shape of the sonar beam, which causes the distance to be greater at the edges

of the beam than at the center of the beam. When this distance change is graphed on

the display, an arch appears.

Fish ID+™: Fish ID+™ is a Humminbird® feature that uses advanced sonar processing

algorithms to determine if a detected object is likely to be a fish. When the sonar signal

from an object meets strict parameters, the unit draws a Fish Symbol (or icon) and the

digital depth of the target. On DualBeam and DualBeam PLUS™ units, fish detected in

the narrow center beam are shown as shaded symbols, and fish detected in the wider

beam are shown as hollow symbols.

Fish Symbol: A Fish Symbol is the graphic that is displayed on the screen when Fish ID+

determines that a sonar return is likely to be a fish. See Fish ID+.

Freeze Frame: Freeze Frame is a Humminbird® feature that pauses the sonar scrolling

so that the image on screen can be studied with greater detail. See Instant Image

Update.

Frequency: Frequency is a measure of the number of sound wave cycles per second of a

sound impulse transmitted underwater. A typical frequency for fishfinders is 200 kHz,

which offers a good balance of performance under many conditions. Lower frequencies,

such as 50 kHz, are capable of penetrating to greater depths, but with less resolution.

Higher frequencies, such as 455 kHz, offer greater resolution, but are limited in depth

performance. Humminbird® uses a variety of frequencies that are optimized for specific

applications.

Grayscale: Grayscale is the use of varying shades of gray to represent the strength of the

sonar signal on the display , and is a very intuitive method of presenting information.

Traditionally, the strongest sonar signals are represented in black, and progressively

weaker signals are represented in progressively lighter shades of gray.

Grayscale, Inverse: Inverse Grayscale is a Humminbird® feature that reverses the

correlation of sonar signal strength and the shade of gray typically used to represent it.

The strongest sonar signals are represented by "white", and progressively weaker

signals are represented in progressively darker shades of gray. While somewhat counter-

intuitive, this method makes the sonar images crisper, and has the benefit of enhancing

_{Download from Www.Somanuals.co}9_m3_{. All Manuals Search And Download.}

the apparent sensitivity because the weaker signals appear bolder. Inverse grayscale

works well in very clear water. Debris-laden water often appears as a lot of clutter on

the screen.

Instant Image Update: Instant Image Update is a Humminbird® feature that updates all

the sonar information on the display when Sensitivity and a variety of sonar settings

(Bottom View, Range, etc.) are modified. This differs from the traditional functionality

that only updates the new sonar information collected after the setting change. Instant

Image Update permits more accurate fine-tuning of the display because the user can see

the results on the complete sonar graph. When combined with the Freeze Frame

feature, the user can adjust and understand the effects of many different sonar settings

quickly and easily.

Maximum Depth Menu: The Maximum Depth Menu is a Humminbird® feature that

optimizes performance based on the maximum operational depth set by the user.

Many Humminbird® units can operate across a very broad depth range (up to 2500

feet) which causes the unit to "look" up to that full depth under some circumstances.

Due to the speed of sound in water, this can result in less responsiveness because

the unit has to wait for a longer period of time to receive the sonar signal. When the

Maximum Depth menu is set to a lower value, the unit only looks up to the setting,

which increases the responsiveness of the unit. This is an important feature for

anyone operating in shallower depths!

Noise: Noise is unintentional, external sound waves that interfere with the optimal

operation of sonar. Noise appears as random "dots" on the display, and is caused by a

variety of sources. Electrical noise (from trolling motors, bilge pumps, VHF radios)

typically manifests as a consistent dot pattern. Electrical noise can be isolated by

selectively turning on and off other electrical devices to determine the source. Often re-

routing the power cable, or connecting to an alternative power supply (second battery)

can help overcome electrical noise. Hydrodynamic noise (from propeller and/or hull

cavitation) has a more random appearance and is generally related to boat speed, so

that faster operation results in more noise. Hydrodynamic noise can be overcome by

proper transducer installation. Many Humminbird® products have a Noise Filter menu

setting that allows the user to clear the screen of noise that is difficult to eliminate.

Pixels: Pixels are the "picture elements", or small square blocks, that make up the image

on the LCD. Measured as a vertical by horizontal number (i.e. 640 V x 320 H), this key

specification typically indicates the quality of resolution. In fishfinders, the total

_{Download from Www.Somanuals.co}9_m4_{. All Manuals Search And Download.}

resolution (vertical multiplied by horizontal) is often less important than the "Vertical

Pixel" resolution. See Pixels, Vertical.

Pixels, Vertical: Vertical Pixels are a number of vertical picture elements in a single

column on an LCD display. A greater number of vertical pixels provide finer resolution of

targets detected by sonar. Essentially, a vertical distance (the depth), when divided by a

larger number, breaks that distance into smaller samples, each representing a smaller

area and thus providing more detail. In fishfinders, vertical pixels are more critical than

horizontal pixels because the horizontal axis of the display represents time, or history.

Sonar information on the horizontal axis can vary greatly, depending on boat speed and

the Chart Speed setting. A greater number of horizontal pixels show more sonar history

that the boat has passed through. On many models, Humminbird® provides the most

vertical pixels to provide a better display resolution. See Chart Speed and Pixels.

Power Output: Power output is the amount of sound energy emitted into the water by

the sonar transmitter. Power output is measured using either RMS (Root Mean Square)

or P-T-P (Peak-to-Peak) measurement systems. Either method is acceptable, but it is

important, when comparing power outputs, to make sure that the same measurement

system is being used for both outputs, because P-T-P numbers are 8 times higher than

RMS numbers. Greater power output allows the sonar signal to penetrate through

weeds and thermoclines, reach deeper depths and operate more effectively in noisy

environments, such as when the boat is running at high speed.

Pulse Width (Pulse Length): Pulse Width is the length of time that a sonar sound burst

is transmitted into the water. Shorter pulse widths provide better target separation, but

cannot travel to great depths. Longer pulse widths provide better depth penetration, but

result in poorer target separation. Humminbird® varies pulse width based on depth to

optimize both target separation and depth performance. See Target Separation.

QuadraBeam™: QuadraBeam™ is a Humminbird® sonar configuration that uses four

sonar beams for a more detailed bottom image. QuadraBeam™ uses the DualBeam

PLUS™ configuration for downlooking, and also adds two additional beams to look to

the left and right. The sonar beams pointing to the left and right provide the ability to

spot fish and structure over a wide 90° area, and to identify on which side of the boat

they are located. See DualBeam PLUS™.

Quick Disconnect Mount: The Quick Disconnect Mounting system is an exclusive

Humminbird® feature that permits the unit to be easily removed from the mounting

base by pressing a release button, and re-installed by simply snapping it back into place.

_{Download from Www.Somanuals.co}9_m5_{. All Manuals Search And Download.}

All cable connections are made when installing, so that no separate wiring connections

are required. Additionally, the mount offers 90° tilt and 360° swivel capability to adjust

the viewing angle of the unit as you move about the boat.

Real Time Sonar: Real Time Sonar is a Humminbird® technology that delivers ultra-fast

sonar transmitter/receiver operation and results in a more detailed instantaneous view

of what is under the boat. The Real Time Sonar window is a vertical band at the right side

of the display that shows the instantaneous sonar return from the transducer at a

particular instant. The RTS® Window menu option permits the user to adjust the

window to show the full sonar signal return, or just a narrower band that indicates

intensity using grayscale. Real Time Sonar relies on very fast Sonar Update Rate (Ping

Speed). See Sonar Update Rate.

Receiver: See Transmitter.

Second Return: The Second Return is a term that describes the appearance of a second

sonar return below the primary sonar return (bottom contour) at exactly twice the true

depth. The second return is caused by the same sonar energy bouncing off the bottom

once, rebounding to the water surface and then traveling back down to the bottom to

be reflected again. Second returns are more common in shallow water and over hard

bottoms; it is actually possible to see a third sonar return under some circumstances.

The second return provides useful information to help determine bottom hardness, as

areas with harder bottoms will generally create a second return. The second return can

be used as a guide to set Sensitivity when in shallower water.

Sensitivity: Sensitivity is a user feature that adjusts the sensitivity of the sonar

system to show more or less detail in the water. Higher sensitivities are often

preferred, however, when the water contains debris (silt, storm debris, etc.) and it

can be difficult to pick out targets. Conversely, if sensitivity is set too low, relevant

targets may be missed.

SONAR: SONAR is the acronym for SOund and NAvigation Ranging. Sonar technology

uses precision sound bursts transmitted underwater to determine the distance and

other attributes of objects in the water. Distance can be determined because the speed

of sound in water is constant, and the time for the signal to return is measured. Sound

also travels very quickly underwater, making sonar a responsive, cost-effective tool.

Sonar is the basic technology behind all recreational and commercial fishfinding and

depthfinding devices.

_{Download from Www.Somanuals.co}9_m6_{. All Manuals Search And Download.}

Sonar Echo Enhancement: Sonar Echo Enhancement is a Humminbird® feature that

describes the high degree of sonar sensitivity achieved through a combination of

transmitter/receiver and software algorithms. The result of Sonar Echo Enhancement is

to display virtually everything in the water that is of interest to the angler, including bait

fish, game fish, thermoclines, weed beds, subtle structure, and more.

Sonar Update Rate: Sonar Update Rate is the number of times per second that the

transmitter/receiver sends and receives sonar signals. A very fast sonar update rate collects

more information and provides a more detailed image of the bottom, fish and structure.

Many Humminbird® units operate at up to 40 times per second when in single frequency

operation. Due to the limitation of the speed of sound in water, the update rate begins to

slow as depth increases to deeper than 50 feet. In very shallow water (less than 10 feet),

however, update rates as much as 60 times per second can be achieved.

Speed: Speed is the rate at which the boat moves through the water. Boat speed can be

measured as Speed Over Ground or Speed Through Water. Speed Over Ground is

provided by GPS, and is the measurement of the boats progress across a given distance.

Speed Through Water is provided by a speed paddlewheel, and is the measurement of

the flow past the boat, which may vary depending on current speed and direction.

Speed Through Water is most critical for anglers using downriggers, as it impacts the

running depth of the down riggers. Speed Over Ground is optimal for navigation, as

accurate destination times can be derived from this measurement. Humminbird®

products allow for input and display of both sources.

Structure: Structure is a general term for objects on the bottom that present a

discontinuity and are a likely attractor for fish. This includes bottom contour features

(drop-offs, humps, and holes), standing structure (stumps, timbers, brush piles) and a

wide range of other potential objects (sunken boats, reefs). Humminbird® units excel at

showing structure with great detail over a wider area due to unique sonar

configurations developed for the angler.

Structure ID®: Structure ID® is a Humminbird® feature that describes the traditional

grayscale method of presenting sonar information. See Grayscale.

Surface Clutter: Surface Clutter is a phenomenon where sonar returns are reflected off

of tiny objects near the surface of the water, including algae and even air bubbles.

Typically, saltwater environments have significantly greater surface clutter than

freshwater due to continuous wind and wave action that causes aeration at the surface.

The Surface Clutter menu provides manual control to bias the default settings under

extreme conditions.

Target Separation: Target Separation is the measurement of minimum distance that

a fishfinder needs to be able to recognize two very close objects as two distinct

targets (i.e. two fish hanging very close, or a fish hanging very close to structure).

Humminbird® fishfinders provide a very good 2 1/2 inches of target separation in

shallower than 100 feet of depth. Target separation decreases as depth increases

due to the need for longer Pulse Width to achieve greater depth. See Pulse Width.

Thermoclines: Thermoclines are water layer(s) of distinctly different temperatures that

create a sonar reflection due to the density of the differing water temperatures. Typically

a thermocline will appear as a continuous band across the display at some distance

above the bottom contour. Thermoclines are of interest to anglers because fish will

suspend above or below the thermocline as they seek the optimum temperature and

oxygen levels.

Time Variable Gain: Time Variable Gain is a processing step applied to the sonar return

to "normalize" the data so that objects of equal size (i.e. fish) appear to be the same size,

even if they are separated by a good distance. Time Variable Gain is a fundamental

attribute of good sonar, but is often promoted as a feature.

Total Screen Update®: A Humminbird® feature that refreshes and updates all the sonar

information on the display when a range change occurs. Without Total Screen Update®,

only the most recent sonar information would be drawn to the new range, and the old

sonar information would continue to scroll off the screen at the old range.

Transducer: The transducer is part of the sonar system, which mounts on the boat

and is in contact with the water, that converts the electrical energy from the

transmitter into sound energy, and that forms the sonar beam in turn. Internally, the

transducer consists of one or more piezo electric disks that expand by very minute

amounts to create the sound wave. This element also works in reverse, converting

the returned sound energy back into an electrical signal that the receiver interprets.

Transducers are available for many specific mounting applications for the boat, such

as a transom mount, trolling motor mount, etc. Humminbird® offers many

sophisticated transducers, often with multiple piezo electric elements designed to

form specifically-shaped sonar beams, providing the angler with superior tools for

finding and catching fish. See Transmitter and SONAR.

Transmitter: The transmitter and receiver are matched parts of the sonar system that

send (transmit) and listen to (receive) the sonar signals, and work in conjunction with

the transducer. Humminbird® transmitters have an extremely fast cycling design that

_{Download from Www.Somanuals.co}9_m8_{. All Manuals Search And Download.}

can send signals up to 60 times per second, as well as produce the varying levels of

power output needed for different depths and conditions. Additionally, the transmitter

has the capability to create very precise sonar pulses needed for a high degree of target

separation. Humminbird® receivers are extremely sensitive, but within a narrow

"bandwidth" to discriminate against noise from external sources. Additionally, the

receiver offers a wide "dynamic range" which provides the ability to receive very strong

signals alternating with very weak signals, without the strong signal overwhelming the

weak signal. See Transducer and Noise.

TripLog: TripLog is a Humminbird® feature that provides an on-screen counter for

Elapsed Time, Average Speed and Total Distance traveled, and requires a speed input to

activate the feature. TripLog appears on the Big Digits View, and can be reset to zero

through the TripLog menu.

TrueArch®: TrueArch® is a Humminbird® feature that provides true fish arches, not

artificial arches or symbols. Humminbird® units are capable of producing fish arches due

to the wide 60° sonar beam of DualBeam PLUS™, an extremely sensitive sonar receiver.

See Fish Arch.

Viewing Angle: Viewing Angle is an attribute of an LCD that characterizes visibility of the

display when viewing from off the central access, such as when standing to the side of

the fishfinder. Wider viewing angles are better because the information remains visible

even when viewing from the side.

WhiteLine®: WhiteLine® is a Humminbird® feature that highlights the strongest sonar

return on the display using a very light gray band. This is preferred by some anglers who

have grown accustomed to the feature on paper graph chart recorders.

WideSide®: WideSide® is a Humminbird® sonar configuration used in an optional

transducer. WideSide® uses three sonar beams pointing to the left, right and down.

Beams pointing to the left and right are effective for spotting fish and structure near the

surface or on the bank. The downlooking beam provides depth information directly

below the boat.

X-Press™ Menu: X-Press™ Menus are a Humminbird® feature that make the most

commonly-used menu selections available with one press of the MENU key. Items

that appear on the X-Press™ Menu are related to the current view, and present the

most logical choices for that view. Sonar View X-Press™ menus will differ from Chart

View X-Press™ menus, etc. X-Press™ menus are one of the principal reasons that

Humminbird® products are easier to use.

Zoom: Zoom is a feature that focuses in on a smaller area of the bottom to provide

enhanced resolution. With enhanced resolution, the angler can more easily see fish

hanging in structure or multiple fish hanging close together. Split screen zoom divides

the display into the full range view on the right, and the zoomed view on the left.

Humminbird® offers One-Touch® Zoom which allows the zoom feature to be easily

accessed from the regular sonar view with just one key press, eliminating the need to

use menus to access the feature.

Zoom, Bottom Lock: Bottom Lock Zoom is a feature that focuses on a smaller area just

above the bottom to provide enhanced resolution. Unlike regular zoom, it continuously

graphs the bottom at a constant point on the display regardless of changes in depth.

This "flattens" out the bottom contour, but is effective at showing fish on or near the

bottom, and is preferred by many saltwater anglers.

GPS & Navigation Terms:

Acquisition Time: The length of time that a GPS receiver typically takes to determine a

position from at least three satellites. Humminbird® GPS receivers provide very fast

acquisition times (under one minute), permitting users to get out on the water faster.

Alarm, Arrival: The audible alert that sounds when the boat is equal to or less than the

alarm setting (25 feet–3000 feet) from the location of the destination waypoint.

Alarm, Drift: Drift Alarm is an audible alert that sounds when the boat is equal to or over

the alarm setting (25 feet–3000 feet) from the location where the alarm was turned on.

Alarm, Off-Course: Off-Course Alarm is an audible alert that sounds when the boat’s

distance from the intended Track, (Cross Track Error), is equal to or over the alarm setting

(25 feet – 3000 feet). See Track and Cross Track Error.

Altitude: Altitude measures height above sea level. Altitude is a measurement that can

be provided by GPS.

Bearing (BRG): Bearing is the direction to a destination waypoint measured in degrees

from North (i.e. 321°, where 000° is North, 090° East, 180° is South, 270° is West).

Chartplotter: Chartplotter describes a navigation device that shows Present Position on

a Map, along with Tracks, Waypoints, and Routes. All Chartplotters are also considered

Trackplotters. All Humminbird® GPS Combo units are Chartplotters. See Trackplotter.

Cold Start: Cold Start refers to the procedure that a GPS receiver must perform when it

does not have historical information regarding its current location. This procedure

typically lasts for several minutes, and may be experienced upon first power up of the

receiver, or if the receiver has been moved a great distance.

Course Over Ground (COG): Course Over Ground is the current direction the boat is

traveling measured in degrees from North (i.e. 321°, where 000° is North, 090° East, 180°

is South, 270° is West). When the Course Over Ground is equal to Bearing, the boat is

said to be “On Course” and will arrive at the destination in the most efficient manner.

COG is often confused with Heading. See Heading.

Cross Track Error (XTE): Cross Track Error is the straight-line distance of the boat from

the intended Track. XTE measures how far the boat is off course, and also triggers the

Off Course Alarm. See Track.

Differential GPS (DGPS): Differential GPS is a system to improve the position accuracy

of the Department of Defense GPS through the use of secondary “correction signals”

broadcast from ground stations around the coastal United States and on some inland

waterways. These correction signals are provided by the USCG and received by an

auxiliary Differential Beacon Receiver (DBR) that connects to the GPS receiver. The

advent of WAAS has largely negated the need for the added expense of a DBR in the

United States.

Distance To Go: Distance To Go is the straight-line distance between Present Position

and the Destination Waypoint. DTG and SOG (Speed Over Ground) are used to calculate

Time To Go. See Time to Go and Speed Over Ground.

Estimated Position Error (EPE): Estimated Position Error is a calculation that indicates the

potential position inaccuracy the user may experience due to a variety of GPS factors

which include satellite position in the sky, signal strength and others factors.

Fix Type: Fix Type indicates whether the GPS receiver is providing 2D fix or 3D fix. A 2D

fix requires only three satellites and provides only latitude and longitude. A 3D fix

requires four or more satellites, and provides latitude, longitude and altitude.

GPS: GPS is an acronym for Global Positioning System. GPS provides accurate position

(latitude, longitude, altitude) information virtually anywhere on the earth through

satellite technology and personal receivers on the ground. A series of geosynchronous

satellites broadcast a unique signal toward the earth once per second. A GPS receiver,

101

Download from Www.Somanuals.com. All Manuals Search And Download.

such as that included with many Humminbird® products, receives the signals from

these satellites and is able to determine position based on very slight differences in

the time each signal is received and the receiver’s knowledge of the location of each

of the satellites.

Heading: Heading describes the direction the boat is pointing and is measured in

degrees (i.e. 321°, where 000° is North, 090° East, 180° is South, 270° is West). Due to

wind and waves, the boat is often traveling in a slightly different direction than it is

heading, and therefore Heading is often confused with Course Over Ground. See

Course Over Ground.

Map Datum: A Map Datum refers to a particular survey of the earth’s surface that was

referenced when creating a chart (i.e. WGS84). Since the earth is not flat, and not even

consistently round, a mathematical model must be used to translate coordinates from

the sphere of the earth to the flat surface of a chart. This mathematical model is the

Map Datum. Historically, many different Map Datums have been used around the world

to create maps; often a reference to the Map Datum can be found in the legend of a

paper map. It is important to select the correct Map Datum setting in your fishfinder

when comparing GPS position to a paper chart to avoid slight position inaccuracies.

Almost all electronic charts use the WGS84 Map Datum and therefore, they do not

require setting changes.

MMC: MMC is an acronym for Multi Media Card. An MMC is a postage stamp-sized

memory device used to store electronic data such a maps, waypoints, routes and other

information. MMC is a very rugged format suitable for the marine environment, but it is

not waterproof. The MMC is removable from Humminbird® products, and can be used

in a PC that is equipped with an appropriate card reader. MMC is the same format that

many digital cameras use. See SD.

North, Magnetic: North is the principle reference point of the compass (i.e. North is

000°). Magnetic North relies on the earth’s magnetic field to align a metal pointer

generally towards True North. However, due to local variations in the earth’s magnetic

field around the globe, the difference between True North and Magnetic North can be

greater than 10°. See True North.

North, True: North is the principle reference point of the compass (i.e. North is 000°).

True North uses the axis of the rotation of the earth as the reference for North and is

constant for all points on the earth. Most GPS units default to True North as the setting.

The GPS heading may vary from the boat compass heading because the compass uses

102

Magnetic North. Humminbird® GPS units provide the option of selecting True or

Magnetic readouts by using the North Reference menu. See Magnetic North.

Present Position: Present Position is the current location (latitude, longitude)

determined by GPS. The Present Position is indicated on-screen by a directional boat icon

if the boat is moving, or a round symbol if the boat is stationary.

Route: A Route is series of waypoints linked together in a specific sequence to define

a navigation path between two points, and saved in the fishfinder’s memory. Routes

are often used when frequently traveling between two or more locations because it

is a faster and more accurate method than repeatedly selecting individual waypoints

each time one travels through the same area. Routes consist of a Start Waypoint, an

End Waypoint, and a series of waypoints in between. Users can begin navigation at

the beginning, the end (to run the route in reverse) or at any waypoint in between.

See Waypoint.

SD: SD is an acronym for Secure Digital. An SD card is virtually identical in function to an

MMC; however, the speed at which information can be accessed is generally faster, the

storage capacity is generally larger, and the card has security features which can be used

to prevent extracting the data from the card. SD is the same format that many digital

cameras use. See MMC.

Selective Availability: Selective Availability (SA) is a GPS system “feature” that can be

implemented by the U.S. Department of Defense (DoD) to degrade the accuracy of GPS

positioning information. With SA active, the GPS is accurate to within 100 meters 95%

of the time. With SA inactive, the GPS is accurate to within 45 meters 95% of the time.

Currently, SA is inactive and the consumer can enjoy the greater precision GPS provides;

however, the DoD reserves the right to activate SA at any time.

Speed Over Ground (SOG): Speed Over Ground is the measurement of the boat’s

progress across a given distance, and is the speed measurement provided by GPS. An

alternate, Speed Through Water, is provided by a speed paddlewheel, and is the

measurement of the flow past the boat, which may vary depending on current speed

and direction. Speed Over Ground is optimal for navigation because accurate

destination times can be derived from this measurement. Humminbird® products allow

for input and display of both speed measurements.

Time To Go (TTG): Time To Go is the estimated time required to reach the destination

waypoint. TTG is calculated using the SOG and DTG. See SOG and DTG.

103

Track: A Track is a series of saved points that define the past path of the boat. These Track

Points are saved at regular time intervals. Tracks are a useful and quick method to see

where you’ve been, and an easy guide to follow to get you back to the starting point.

Generally, all GPS units have a limited number of Track Points that can be saved before

the unit runs out of memory and begins erasing the first track points saved. Because of

this, the user can adjust the Track Point Interval menu to increase the amount of time

between when points are saved, and thus extend the distance covered by a track. Tracks

can also be permanently saved to memory, and re-displayed at the user’s option.

Track Line (TRK): The Track Line is the desired line of travel between two waypoints, and

represents the most efficient path between the two points because it is a straight line.

The TRK is measured in degrees (i.e. 321°, where 000° is North, 090° East, 180° is South,

270° is West). See Cross Track Error, Course Over Ground.

Trackplotter: Trackplotter describes a navigation device that shows Present Position,

along with Track, Waypoint, and Routes, but NO MAP in the background. See

Chartplotter.

Trolling Grid: Trolling Grid is a Humminbird® feature that displays a precise reference

grid around a waypoint. This grid is used as a guide pattern for trolling around a specific

area to assure a more efficient and complete coverage of that area. Trolling Grid

resolution be changed by zooming in or out on the chart. The Trolling Grid can also be

rotated on the display to orient it for optimal boat course for wave and wind conditions.

UTC: UTC is an acronym for Universal Time Constant. UTC is the “standard time” used in

navigation, and is the local time in Greenwich England. (UTC is equivalent to Greenwich

Mean Time (GMT)). To display the correct Local Time in a Humminbird® GPS unit, the

user must use the Local Time Zone menu and select the time zone (i.e. EST, CST).

WAAS: WAAS is an acronym for Wide Area Augmentation System. WAAS is

complementary technology to GPS that provides enhanced accuracy through correction

signals broadcast from Federal Aviation Administration WAAS satellites stationed over

the USA. These secondary signals are automatically received by the standard

Humminbird® GPS Receiver. With WAAS signal, GPS accuracy is improved to within 3

meters 95% of the time. Outside the United States, regional governmental coalitions

have created similar systems such as EGNOS (Europe) and MSAS (Japan).

Waypoint: A Waypoint is the saved location (latitude, longitude) of a point of interest

that is stored in a GPS receiver’s memory. This can include a marker buoy, dock, fishing

104

hole or anywhere else the user may want to return to. Humminbird® products offer the

ability to name and assign a symbol to the saved location. Depth, Date and Time of Day

when the waypoint was created is also saved.

Waypoint Target: Waypoint Target is a Humminbird® feature that displays a precise

“bull’s eye” around a selected waypoint. This bull’s eye is used to easily monitor boat

position relative to a waypoint, and is useful for fishing over submerged structure. With

Waypoint Targets, a quick look at the screen lets you know how far off the waypoint the

boat has drifted.
