How Sonar Works  
Sonar technology is based on sound waves. The 700 Series™ Fishing System  
uses sonar to locate and define structure, bottom contour and composition, as  
well as depth directly below the transducer.  
Your 700 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.

531526-1_A - 747c_&_777c2_Man_Eng.qxp 10/2/2006 1:40 AM Page 7  
The sound pulses are transmitted at various  
frequencies depending on the application. Very  
high frequencies (455kHz) are used for greatest  
definition but the operating depth is limited. High  
frequencies (200kHz) are commonly used on  
consumer sonar and provide a good balance  
between depth performance and resolution. Low  
frequencies (83kHz) 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 700 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.

QuadraBeam PLUS™ Sonar  
(with optional-purchase QuadraBeam PLUS™  
transducer)  
Your 700 Series™ Fishing System also  
supports QuadraBeam PLUS™ sonar with  
the purchase of an additional QuadraBeam  
PLUS™ transducer. QuadraBeam PLUS™  
sonar provides an extremely wide 90° area  
of coverage. QuadraBeam PLUS™ starts  
with two fan-shaped 35° 455 kHz Side  
Structure locating sonar beams to spot fish,  
bait and structure to the left and right of the  
boat over an area of the bottom that’s  
always equal to twice your depth. For a  
detailed view below the boat, QuadraBeam  
PLUS™ uses DualBeam PLUS™ technology,  
with precision 20° and wide 60° beams.  
QuadraBeam PLUS™ finds more fish faster,  
and can even tell you where to put your bait  
by showing if fish are to the left, right or  
directly beneath your boat.

WideSide® Sonar  
(with optional-purchase WideSide® transducer)  
Your 700 Series™ Fishing System also supports  
WideSide® sonar with the purchase of  
an additional WideSide® transducer. The  
WideSide® transducer is a specialized "side-  
looking" transducer that is extremely useful for  
bank fishing or looking for bait fish in open  
water. The WideSide® transducer uses three  
different sonar elements that transmit signals to  
the left, right and straight down from your boat.  
The downward beam is 200 kHz with a 24° area  
of coverage. This beam maintains a continuous  
digital depth readout from the bottom directly  
beneath your boat. The side beams are 455 kHz  
with a 16° area of coverage. The side-looking  
elements can be used independently, or  
together to locate targets near the surface of  
the water on either side of your boat.

Universal Sonar 2  
Your 700 Series™ Fishing System supports Universal Sonar 2, a state-of-the-  
art, integrated and protected transducer that is built into the lower unit of  
Minnkota trolling motors. With Universal Sonar 2, all wiring is concealed inside  
the indestructible composite shaft—out of sight and out of harm’s way, with  
no clamps, ties, or exposed wires. Universal Sonar 2 features new temperature  
sensing and the performance of DualBeam PLUS™ technology (available with  
all Humminbird® DualBeam PLUS™ models). An expanded view and greater  
bottom detail gives you a totally new perspective of the water below, along  
with optimal sonar performance to help you find fish.

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 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 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. Red  
indicates a 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.  
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. The  
Wide RTS® Window does not  
make use of grayscale.  
Freeze Frame and Cursor  
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 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.

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.

Side Beam View  
(with optional-purchase QuadraBeam PLUS™ transducer)  
Side Beam View is only available if you have connected an optional-purchase  
QuadraBeam™ transducer accessory and when Transducer Select is set to  
QuadraBeam (see Sonar Menu Tab: Transducer Select). The QuadraBeam  
PLUS™ transducer requires a separate purchase. This view shows sonar  
information from both the left and right 455 kHz beams and the 200 kHz down-  
looking beam in one view. You can customize the way the sonar data is  
displayed in the Side Beam View to suit your personal preferences. Depending  
on the layout selected from the Quad Layout Sonar X-Press™ menu (only  
available on the Sonar X-Press™ menu when in Side Beam View), the display  
will represent the same sonar data in one of the following three layouts:  
Default, Classic, and Slanted.  
Default layout: The top portion of the display presents a historical log of sonar  
returns from the 200 kHz down-looking sonar beam. New information in the  
down beam panel scrolls from right to left. The bottom portion of the display  
presents a historical log of sonar returns from the 455 kHz right- and left-  
looking sonar beams. New information in the side beam panels scrolls from the  
center out.

Simulator  
Use the Simulator to learn how to use your 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 (shown with optional-purchase  
Weathersense® attached)  
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 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  
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 Fishing System off.

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,  
455 kHz Balance or Wideside Sensitivity) which allow you to adjust the level of sensitivity for  
one specific beam at a time.  
Sensitivity at Medium  
Sensitivity at Low  
Sensitivity at High  
To adjust the Sensitivity:  
1. Highlight Sensitivity on the Sonar X-Press™ Menu.  
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or  
decrease the Sensitivity setting. (Low = 1, High = 20, Default = 10)

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™ Menu.  
2. Use the LEFT or RIGHT 4-WAY Cursor Control keys to increase or  
decrease the Upper Range setting. (0 to 1490 feet or 0 to 497 meters  
[International Models only], Default = 0)

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™ Menu.

Side Beam Range  
(WideSide® transducer: WideSide® view only)  
Side Beam Range sets the deepest range that will be displayed in the  
WideSide® View. The range must be set manually to keep the bottom visible on  
the display. If the Side Beam Range is set too deep for current depth conditions  
the sonar information will become compressed on the display and valuable  
detail will be lost. A WideSide® transducer must be connected to your Fishing  
System. Side Beam Range menu choice is available when Transducer Select is  
set to WideSide® (see Sonar Menu Tab: Transducer Select) and can only be  
accessed from the WideSide® view.  
NOTE: The Side Beam Range requires the purchase of the WideSide® transducer. You can visit  
our website at www.humminbird.com to order this accessory online or contact our Customer  
Resource Center at 1-800-633-1468.  
To adjust the Side Beam Range:

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 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)  
Quad Layout  
(with Optional-Purchase QuadraBeam PLUS™  
Transducer, Side Beam View only)  
Quad Layout selects the method used to represent the sonar information from  
the two side-looking beams plus the down-looking beam to be presented on  
the Side Beam View, and is only available when an optional-purchase  
QuadraBeam PLUS™ transducer is attached and the Side Beam View is active.  
Use Quad Layout to change the way the Side Beam View is displayed. See Side  
Beam View for more information.  
To adjust the Quad Layout:  
1. Highlight Quad Layout on the Sonar X-Press™ menu.

Beam Select  
Beam Select sets which sonar returns from the  
transducer will be displayed on the screen.  
When set to 200/83 kHz, the returns from both beams are blended by  
starting with the 83 kHz wide beam return, dimming it, and then overlaying  
it with the 200 kHz narrow beam return. The darker 200 kHz narrow beam  
sonar returns will stand out from the paler 83 kHz wide beam sonar returns.  
The Split Sonar View continues to display the sonar returns from each beam  
in their respective windows. The blended information is shown in the Sonar  
View, Sonar Zoom View and the Big Digits View. The RTS® Window in the  
Sonar View and the Circular Flasher View will only show the returns from the  
200 kHz narrow beam.  
When set to 200 kHz, only the returns from the 200 kHz narrow beam will be  
displayed in the Sonar View, the Sonar Zoom View, the Big Digits View and  
the Circular Flasher View. The Split Sonar View will continue to display returns  
from both beams in their respective windows. The RTS® Window in the Sonar  
View will display the returns from the 200 kHz narrow beam.  
When set to 83 kHz, the returns from the 83 kHz wide beam will be displayed  
in the Sonar View, the Sonar Zoom View, the Big Digits View and the Circular  
Flasher View. The Split Sonar View will continue to display returns from both

Fish ID+™  
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 PLUS™ sonar 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.  
83 kHz, Wide Beam  
Blue Fish Symbols  
200 kHz, Narrow Beam  
Orange Fish Symbols  
When Fish ID+™ is turned off, the 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+™

Fish ID Sensitivity  
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 Fishing System to identify sonar returns as fish.  
To change the Fish ID Sensitivity setting:

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.  
700 Series™ Doesn’t Power Up  
If your 700 Series™ 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 700 Series™ 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.  
700 Series™ Defaults to Simulator with a Transducer Attached  
A connected and functioning transducer will cause the newly-started Fishing  
System to go into Normal operating mode automatically. If, when you power up  
the 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 Fishing System,  
check to make sure that the transducer cable is securely connected to  
the Fishing System. Reconnect if necessary, and power up the 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.

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 Isolation  
Other electronic devices  
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.  
Cavitation from the boat’s  
propeller  
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:  
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.  
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 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.

531526-1_A - 747c_&_777c2_Man_Eng.qxp 10/2/2006 1:42 AM Page 88  
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. 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. 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 PLUS™: QuadraBeam PLUS™ is a Humminbird® sonar  
configuration that uses four sonar beams for a more detailed bottom image.  
QuadraBeam PLUS™ 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. 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.  
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 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.
