How Sonar Works  
Sonar technology is based on sound waves. The 500 Series™ Fishfinder uses  
sonar to locate and define structure, bottom contour and composition, as well  
as depth directly below the transducer.  
Your 500 Series™ Fishfinder 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 uses 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.  
How Sonar Works  
2
Download from Www.Somanuals.com. All Manuals Search And Download.  
When all the echoes are viewed side by side, an  
easy to interpret “graph“ of the bottom, fish, and  
structure appears.  
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 Sonar  
Your 500 Series™ Fishfinder uses a 200/83 kHz  
DualBeam sonar system with a wide (60°) area  
of coverage. DualBeam sonar is optimized to  
show the greatest bottom definition using a  
narrow (20°) beam yet can still indicate fish  
found in the wide (60°) beam when the  
Fish ID+™ feature is turned on. DualBeam 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 Works  
Your 500 Series™ Fishfinder also supports GPS (Global Positioning System) and  
chartplotting. It uses GPS and sonar to determine your position, display it on a  
grid, and provide detailed underwater information.  
GPS uses a constellation of satellites that  
continually send radio signals to the earth. 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.  
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.  
The following GPS functionality is currently supported by the 500 Series™  
Fishfinder when it is connected to the included GPS receiver:  
• 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.  
See Chart View and Introduction to Navigation: Add Maps to Your Fishfinder  
for more information.

Hollow Fish Symbol (83kHz, Wide Beam)  
Fish - The Fishfinder displays fish as arches  
and/or fish icons, and can be set to alarm  
when a fish of a certain size is detected.  
When a target is detected, a Fish ID+™  
symbol appears on the display with the  
depth displayed above it. The size of the  
symbol indicates the intensity of the sonar  
return. The unit will clearly show schools of  
Bait Fish as "clouds" of different shapes and  
sizes, depending on the number of fish and  
boat speed.  
Thermoclines - Layers of water with different  
temperatures that appear at different depths  
and different times of the year. A thermocline  
typically appears as a continuous band of gray  
levels moving across the display at the same  
depth.

Understanding the Sonar Display  
It is important to understand the significance of  
the 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.  
The returned sonar echoes are displayed on the screen. As a new echo is  
received, the historical data scrolls left across the view.  
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 Windowupdates 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 Windowplots the depth  
and intensity of a sonar return (see Sonar Menu Tab: RTS Window).  
The Narrow RTS Window™  
indicates the sonar intensity  
through the use of grayscale.  
The grayscale used matches  
the Bottom View grayscale  
The Wide RTS Window™  
indicates the sonar intensity  
through the use of a bar  
graph. The length of the  
plotted return indicates  
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

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.

Inverse is a method where weak returns are  
shown with dark pixels and strong returns with  
lighter pixels. This has the benefit of ensuring that  
weak signals will be clearly visible on the display.  
Structure ID® represents weak returns as light  
pixels and strong returns as dark pixels. This has  
the benefit of ensuring that strong returns will be  
clearly visible on the display.  
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.  
Black (Bottom Black) displays all pixels below the  
bottom contour as black, regardless of signal  
strength. This has the benefit of providing a high  
contrast between the bottom and other sonar  
returns on the display.

NOTE: If the Depth number is flashing, it means that the unit is having trouble locating  
the bottom. This usually happens if the water is too deep, the transducer is out of the  
water, the boat is moving too fast, or for any other reason that the unit can’t accurately  
receive continuous data.

Introduction to Navigation  
Use your 500 Series™ Fishfinder to mark waypoints at areas of interest and to  
navigate to those waypoints via a savable route. A route represents the shortest  
intended distance between waypoints. You can also view and save tracks,  
which represent the actual path of the boat.  
Waypoints, Routes, and Tracks  
Waypoints are stored positions (latitude, longitude) that allow you to mark  
areas of interest or navigation points (i.e. a marker buoy, dock, or fishing hole).  
Your Fishfinder can store up to 3000 waypoints.

NOTE: When two or more waypoints overlap, or are displayed close together on a  
chart view, the screen will automatically declutter—waypoint names will shorten  
and the waypoint icons will change into small gray icons.  
To view a Decluttered Waypoint at full size, use the 4-WAY Cursor Control key to  
move the cursor onto a decluttered waypoint icon. When the cursor snaps onto the  
icon, the full-size waypoint name and icon will be displayed. You can also press the  
ZOOM+ key until you can see the individual waypoints on the screen. See  
Navigation Menu Tab: Waypoint Decluttering to turn off this feature.  
Routes link two or more waypoints together to create a path for navigation and  
are used in trip planning. You can link individual waypoints together by using the  
GOTO key. A route represents your intended navigation and shows the shortest  
path from each waypoint to the next. As you travel a route, staying on the route  
line is the most efficient way to get to your destination, although you should  
always look out for obstacles not shown on the chart. Your 500 Series™  
Fishfinder can store up to 50 routes that can each contain up to 50 waypoints.  
Tracks consist of detailed position history and are displayed as a breadcrumb  
trail of trackpoints. The Current Track shows the position history since the unit  
was powered up (maximum of 20,000 trackpoints displayed). You can clear the  
Current Track or save it at any time. Your 500 Series™ Fishfinder can store up  
to 50 saved tracks, each containing 20,000 trackpoints. The current track  
represents your actual path so far.

Simulator  
Use Simulator to learn how to use your Fishfinder before taking your boat on the  
water. The Simulator is a very powerful tool that provides a randomly-updated  
display which simulates on the water operation.  
Simulator  
We recommend going through this  
manual while using the Simulator,  
since all of the menus function and  
affect the display in the same way as  
they would in Normal operation. Any  
menu changes you make will be saved  
for later use.  
NOTE: It is important to select Simulator  
manually from the Start-Up Options  
Menu as opposed to letting the  
Fishfinder enter Simulator automatically  
(as it will if a transducer is not connected  
and you do nothing during power up).  
A message will appear often on the display to indicate Simulator mode.  
To exit Simulator, power off your Fishfinder.  
System Status  
Use System Status to view system connections and to conduct a unit self-test.  
After you select System Status from the Start-Up Options Menu, press the

GPS Diagnostic View shows a sky chart and numerical data from the GPS  
receiver. The sky chart shows the location of each visible GPS satellite with its  
satellite number and a signal strength bar. A dark gray bar indicates that the  
satellite is being used to determine your current position. A light gray bar  
indicates that the satellite is being monitored, but is not yet being used.  
This view also reports the current position, local time and date, and other  
numeric information. The current GPS Fix Type is reported as No Fix, 2D Fix, 3D  
Fix, or Enhanced. An Enhanced fix has been augmented using information from  
WAAS, EGNOS, or MSAS. A 3D or Enhanced Fix is required for navigation.  
HDOP (the Horizontal Dilution of Precision) is a GPS system parameter which  
depends on the current satellite configuration. HDOP is used to calculate the

User Mode (Normal or Advanced)  
Menu options can be simplified or expanded by setting your Fishfinder User Mode  
to Normal or Advanced.  
Normal Mode is the default setting when you first power on your 500 Series™  
Fishfinder. Normal mode is provided for users who want greater simplicity and  
fewer menu choices.  
Advanced Mode is provided for users who want the highest level of control over  
the Fishfinder. Several menu settings are added to the Main Menu when the  
User Mode is changed to Advanced.  
To change the User Mode setting:  
1. Press the MENU key twice to access the Main Menu.  
2. Press the RIGHT Cursor key until the Setup tab is selected.  
3. Press the DOWN Cursor key to highlight User Mode on the Setup main  
menu.

NOTE: Any changes made while in Advanced Mode will remain in effect after you  
switch back to Normal Mode.  
For example, the Select Readouts menu option is available when the User Mode is set  
to Advanced. If you change the Select Readouts settings while operating in Advanced  
User mode, the Select Readouts you choose will continue to display on the screen even  
if you switch back to Normal User Mode.

Sensitivity  
Settings: Low = 1, High = 20; Default = 10  
Sensitivity controls how much detail is shown on the display and will adjust  
the sensitivity of all sonar frequencies.  
When operating in very clear water or greater depths, increase the sensitivity  
to see weaker returns that may be of interest. If the sensitivity is adjusted too  
high, the display may become too cluttered.  
Decrease the sensitivity to eliminate 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.

Upper Range  
(Advanced: Sonar and Big Digits Views only)  
Settings: 0 to 790 ft or 0 to 257 m [International Models  
only]; Default = 0  
Upper Range sets the shallowest depth range that will be displayed on the Sonar  
and Big Digits 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). Greater detail will be shown  
for the 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.  
Lower Range  
Settings: AUTO, 10 to 800 ft, 3 to 260 m [International  
Models only]; Default = AUTO  
Lower Range sets the deepest depth range that will be displayed by the unit.  
Auto: The Lower Range will be adjusted by the unit to follow the bottom  
automatically. Auto is the default setting.  
Manual: You can adjust the Lower Range to lock the unit on a particular depth.  
“M” will be displayed in the lower right corner of the screen to indicate the unit  
is in Manual mode. Adjust the Upper and Lower Range together to view a  
specific depth range, especially when looking for fish or bottom structure.  
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, which allows 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.

Chart Speed  
Settings: 1-9, Ultra, where 1 = Slow, 9 = Fast, Ultra =  
Fastest; Default = 5  
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 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 Windowwill update at the maximum rate possible for  
the depth conditions.  
Bottom View  
Settings: Inverse, Structure ID®, WhiteLine™, Bottom  
Black; Default = Inverse  
Bottom View selects the method used to represent bottom and structure on the  
display. See What’s on the Sonar Display: Bottom Presentation for more  
information.

TVG  
Settings: On, Off; Default = On  
TVG (Time Variable Gain) adjusts the sonar returns on the display to show less  
clutter and more fish size accuracy. In other words, when TVG is On, a large  
arch on the display means a large fish has been detected.  
When TVG is off, the Fishfinder shows only the raw sonar returns on the  
display. While the raw data may create more clutter on the display, it also  
reveals more arches and better jig tracking on the screen.

Fish ID+™  
Settings: Off, On; Default = On  
Fish ID+™ uses 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 sonar models represent targets detected in the 200 kHz narrow  
beam as Shaded Fish Symbols and targets detected in the 83 kHz wide beam  
as Hollow Fish Symbols.  
200 kHz, Narrow Beam  
Shaded Fish Symbols  
83 kHz, Wide Beam  
Hollow Fish Symbols  
When Fish ID+™ is turned off, the Fishfinder 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.

Fish ID Sensitivity adjusts the threshold of the Fish ID+™ detection 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+™. Fish ID+™ must be  
On for Fish ID Sensitivity to affect the ability of the Fishfinder to identify sonar  
returns as fish.  
Real Time Sonar (RTS™) Window  
Settings: Wide, Narrow, Off; Default = Narrow  
RTS Windowsets the RTS Windowto either Wide or Narrow, or turns it off  
in the Sonar View. The RTS Windowalways updates at the fastest rate  
possible and only displays returns that are within the transducer beam. See  
What’s on the Sonar Display for more information.  
NOTE: The Wide RTS Window™ does not use grayscale.

Noise Filter  
(Advanced)  
Settings: Off, Low, Medium, High1, High2, High3;  
Default = Low  
Noise Filter adjusts the sonar Noise Filter to limit interference on the display  
from sources such as your boat engine, turbulence, or other sonar devices.  
The Off setting removes all filtering. Low, Medium, and High1, High2, High3  
settings add progressive filtering of the sonar returns. High1, High2, and High3  
are useful when there is excessive trolling motor noise, but in some deep water  
situations, the High settings may actually hinder your unit’s ability to find the  
bottom.

Max Depth  
(Advanced)  
Settings: AUTO, 10 to 800 ft, 3 to 260 m [International  
Models only]; Default = AUTO  
Max Depth controls the maximum depth of operation. When Max Depth is set  
to Auto, the Fishfinder will acquire bottom readings as needed (within the  
capacity of the unit). When Max Depth is set to match your fishing maximum  
depth, your Fishfinder will not attempt to acquire sonar data below that depth,  
so more detail will be shown on the screen.  
NOTE: If the bottom is deeper than the Max Depth setting, the digital depth readout  
will flash, indicating that the Fishfinder cannot locate the bottom.  
Water Type  
(Advanced)  
Settings: Fresh, Salt (shallow), Salt (deep); Default =  
Fresh)  
Water Type configures your unit for operation in fresh or salt water. In salt  
water, you can also choose the shallow or deep setting.  
Water Type affects the accuracy of deep water depth readings. In salt water,  
what would be considered a large fish might be 2 to 10 times bigger than a  
large fish in fresh water (depending on the type of fish you are seeking). The  
salt water setting allows for a greater range in fish size adjustment to account  
for this difference.

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.  
Fishfinder Doesn’t Power Up  
If your Fishfinder 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 Fishfinder 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.  
Fishfinder Defaults to Simulator with a Transducer Attached  
A connected and functioning transducer will cause the newly-started  
Fishfinder to go into Normal operating mode automatically. If, when you power  
up the Fishfinder, 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 Fishfinder, check  
to make sure that the transducer cable is securely connected to the  
Fishfinder. Reconnect if necessary, and power up the Fishfinder 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.  
There are no fish  
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.  
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.  
Troubleshooting

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.  
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.  
The boat’s engine  
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.

Glossary  
Sonar Terms:  
Beam (Sonar Beam) The wide, cone-shaped projection of sound waves formed as sound  
travels underwater. See Cone Angle.  
Bottom Contour The profile of the bottom graphed to the display as the depth changes.  
Bottom Hardness The density (or composition) of the bottom. Varying levels of hardness  
can be determined by interpreting the “thickness“ of the main 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 The effect of air bubbles created as the propeller rotates and the boat moves  
through the water.  
Cone Angle The angular measurement of the sonar beam at a specific dB down point  
(i.e. -10 dB). See dB Down Point.  
Dead Zone 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 The measurement for sound pressure level, or “intensity”of the sonar return. See  
dB Down Point.  
dB Down Point 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 (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.  
Frequency 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 The use of varying shades of gray to represent the strength of the sonar signal  
on the display. Traditionally, the strongest sonar signals are represented in black, and  
progressively weaker signals are represented in progressively lighter shades of gray.  
Noise The 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. Many Humminbird® products have a Noise Filter menu setting that allows the user  
to clear the screen of noise that is difficult to eliminate (also, see Troubleshooting).  
Pixels The “picture elements“, or small square blocks, that make up the image on the LCD.  
Measured as a vertical by horizontal number (i.e. 640V x 320H), this key specification  
typically indicates the quality of resolution. In fishfinders, the total resolution (vertical  
multiplied by horizontal) is often less important than the “Vertical Pixel“ resolution because  
a greater number of vertical pixels provide finer resolution of targets detected by sonar.  
Sonar information on the horizontal axis can vary greatly, depending on boat speed and the  
Chart Speed setting.  
Power Output The amount of sound energy emitted into the water by the transducer’s  
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) 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.  
Second Return 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 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.

SONAR (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.  
Sonar Update Rate The number of times per second that the transducer’s  
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 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 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).  
Surface Clutter 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.  
Target Separation 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 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 (TVG) 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.  
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. See SONAR.  
Zoom A feature that focuses 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.  
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.  
Altitude The height measurement above sea level. Altitude is a measurement that can be  
provided by GPS.  
Bearing (BRG) 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 A navigation device that shows Present Position on a Map, along with  
Tracks, Waypoints, and Routes. All Chartplotters are also considered Trackplotters.  
Cold Start 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) 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) 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) A system used 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 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) 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 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 (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. See How GPS Works.  
Heading 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 Refers to a particular survey of the earth’s surface that was referenced when  
creating a chart (i.e. WGS84). 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 (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. MMC is the  
same format that many digital cameras use. See SD.  
North, Magnetic 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 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 Magnetic North. See  
Magnetic North.

Present Position 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 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 (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 (SA) 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) The measurement of the boat’s progress across a given  
distance and 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) The estimated time required to reach the destination waypoint. TTG is  
calculated using the SOG and DTG. See SOG and DTG.  
Track 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 planned line of travel between two waypoints, and it 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 and Course Over Ground.  
Trackplotter A navigation device that shows Present Position, along with Track, Waypoint,  
and Routes, but NO MAP in the background. See Chartplotter.  
Trolling Grid 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.  
UTC (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)).  
WAAS (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 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 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 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.
