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.
The sound pulses are transmitted at various
frequencies depending on the application. Very
high frequencies (455 kHz) are used for greatest
definition but the operating depth is limited. High
frequencies (200 kHz) are commonly used on
consumer sonar and provide a good balance
between depth performance and resolution. Low
frequencies (83 kHz) are typically used to achieve
greater depth capability.
The power output is the amount of energy
generated by the sonar transmitter. It is commonly
measured using two methods:
• Root Mean Square (RMS) measures power
output over the entire transmit cycle.
• Peak to Peak measures power output at the
highest points.
The benefits of increased power output are the
ability to detect smaller targets at greater distances,
ability to overcome noise, better high speed
performance, and enhanced depth capability.

DualBeam PLUS™ Sonar
(DualBeam PLUS™ models only [778c HD])
Your 778c HD 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.
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.

Xtreme Depth Sonar
(Xtreme Depth Series™ models only [778c HD XD])
Your 778c HD XD Fishing System uses the XD
transducer to provide extreme depth coverage
with DualBeam PLUS™ technology.
The Xtreme Depth sonar beams can be operated
at two frequencies: 50 kHz (74°) and 200 kHz
(20°). The wide, 50 kHz beam transmits at a low
frequency to provide greater depth coverage, up
to 2500 ft (762 m). The narrow, 200 kHz center
beam transmits at a high frequency to provide
maximum detail at shallower depths.
The DualBeam PLUS™ technology allows you to
view the sonar returns blended together,
separately, or side-by-side (see Sonar Menu
Tab: Beam Select and Views for more
information).
Depth capability is affected by such factors as
boat speed, wave action, bottom hardness,
water conditions, and transducer installation.

WideSide® Sonar
(with optional-purchase 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.

Dual Beam Ice Transducer
(with optional-purchase XI 9 20 Ice
Transducer)
Ice transducer
The XI 9 20 Ice Transducer provides
selectable dual-frequency sonar with a
wide area of coverage. Selectable dual-
frequency gives you the option of two
beams, and both beams will cover the
bottom and provide high definition. The 20
degree center beam provides the highest
definition, while the 60 degree beam
provides wider coverage. Depth capability
is affected by such factors as bottom
hardness and water conditions. Whether
fishing in shallow to very deep water,
selectable dual-frequency is ideal for a
variety of conditions.

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 across the screen.
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™ 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 Tab: 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

display depth scale.
The Wide RTS Window™
indicates the sonar intensity
through the use of a bar

plotted return indicates
whether the return is weak or
strong. The depth of the sonar
return is indicated by the
vertical placement of the

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, Split Sonar, Circular Flasher,
and Big Digits Views only)
Settings: Various, see below.
Upper Range sets the shallowest depth range that will be displayed on the Sonar,
Split Sonar, Circular Flasher, 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.
The available Upper Range settings are determined by your Humminbird® model
as follows:
• 778c HD: 0 to 1490 ft, 0 to 497 m (International Models only);
Default = 0
• 778c HD XD: 0 to 3190 ft, 0 to 972 m (International Models only);
Default = 0
Lower Range
Settings: Various, see below.
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.
The available Lower Range settings are determined by your Humminbird® model
as follows:
• 778c HD: Auto to 1500 ft, Auto to 500 m (International Models only);
Default = Auto
• 778c HD XD: Auto to 3200 ft, Auto to 975 m (International Models
only); Default = Auto
Side Beam Range
(with optional-purchase WideSide® transducer,
WideSide® View only)
Settings: 6 to 160 ft, 2 to 50 m [International Models only];
Default = 160 ft
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.
The Side Beam Range option is available when a WideSide® transducer is
connected to the Fishing System and Transducer Select is set to WideSide® (see
Sonar Menu Tab: Transducer Select). This option can only be accessed from the
Sonar X-Press™ Menu in the WideSide® View.
NOTE: The Side Beam Range requires the purchase of the WideSide® transducer.

Chart Speed
Settings: 1 to 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 Window™ will update at the maximum rate possible for
the depth conditions.
Quad Layout
(with optional-purchase QuadraBeam PLUS™
transducer, Side Beam View only)
Settings: Default, Classic, Slanted; Default = Default
Quad Layout allows you to choose how sonar information is displayed in the
Side Beam View. The Side Beam View displays sonar data from the left and
right 455 kHz beams, as well as the 200 kHz down-looking beam. The sonar
data can be displayed in any of the three layouts by changing the Quad Layout
setting (see Views: Side Beam View).
NOTE: Quad Layout is only available when an optional-purchase QuadraBeam
PLUS™ transducer is attached and the Side Beam View is active (see Sonar
Menu Tab: Transducer Select).

Bottom Range
(Sonar Zoom View only when Bottom Lock is On)
Settings: 10 to 60 feet, 2 to 10 fathoms, or 3 to 20 meters
[International Models only]; Default = 15 ft
Bottom Range allows you to control how much of the water column, measured
up from the bottom, is shown in the Sonar Zoom View. Choose a small value to
see low-lying bottom structure or details of the bottom return. Choose a larger
value to see large structure in deeper water.
NOTE: It is possible to set the Bottom Range to be greater than the depth. In this
case, you may see surface clutter in a wavy band that mirrors changes in the
depth.
Bottom Lock
(Sonar Zoom View only)
Settings: Off, On; Default = Off
Bottom Lock changes the mode of the zoomed view in the Sonar Zoom View.
Bottom Lock continuously graphs the bottom at a constant point on the display
regardless of changes in depth. This “flattens“ out the bottom contour, but is
effective at showing fish on or near the bottom.
Zoom Level
(Sonar Zoom View only)
Settings: 2x, 4x, 6x, 8x; Default = 2x
Zoom Level sets the magnification level for the Sonar Zoom View. Use Zoom to
see more detail in the bottom sonar returns that might be displayed close
together, such as those caused by fish suspended close to the bottom or within
structure.
Zoom Level is only available on the X-Press™ Menu from the Sonar Zoom View.

Choose Max Mode to see only raw sonar returns on the display. When Max
Mode is selected, you will see the maximum sonar information available within
the transducer beam, so more fish arches and better jig tracking are shown.
Choose Clear Mode to see less clutter and more fish size accuracy on the
display. When Clear Mode is selected, the clutter is filtered, and sonar returns
are interpreted to provide more details about the objects within the transducer
beam, regardless of their location. In other words, a large arch on the display
means a large fish has been detected.

Fish ID+™
Settings: Off, On; Default = Off
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.
In the 778c HD, targets detected in the 200 kHz narrow beam are represented
as orange fish symbols, and targets detected in the 83 kHz wide beam are
represented as blue fish symbols.

Blue Fish Symbols
Orange Fish Symbols
In the 778c HD XD, targets detected in the 200 kHz narrow beam are
represented as orange fish symbols, and targets detected in the 50 kHz wide
beam are represented as blue 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.

High 3 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: Various, see below.
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.
The available Max Depth settings are determined by your Humminbird® model as
follows:
• 778c HD: Auto to 1500 ft, Auto to 500 m (International Models only);
Default = Auto
• 778c HD XD: Auto to 3200 ft, Auto to 975 m (International Models
only); Default = Auto
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. The Water Type menu option is
available when User Mode is set to Advanced (see Main Menu: User Mode).
NOTE: Make sure that the Water Type is set accurately, especially in salt
water, as this 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.

transducer (XNT 9 20) and optional-purchase Universal Sonar 2.
NOTE: To purchase transducers, visit our Web site at humminbird.com or call our
Customer Resource Center at 1-800-633-1468.
Ice Fishing Mode
Settings: Off, On; Default = Off
Ice Fishing Mode controls how information is displayed in the Circular Flasher
View. When Ice Fishing Mode is off, the Circular Flasher View displays Real
Time Sonar (RTS™) data in a traditional flasher format.
When Ice Fishing Mode is on, the Circular Flasher View displays the data in
flasher format with additional features including Zoom and Depth Cursor. Also,
the fishfinder’s sensitivity settings are adjusted automatically to accommodate
ice fishing conditions. These settings will apply to the other Sonar Views until
you turn off the Ice Fishing Mode. See Views: Circular Flasher View for more

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.
Fishing System Doesn’t Power Up
If your Fishing System doesn’t power up, use the Installation Guide that also
comes with it for specific confirmation details, making sure that:
• The power cable is properly connected to the Fishing System control
head.
• The power cable is wired correctly, with red to positive battery terminal
and black to negative terminal or ground.
• The fuse is operational.
• The battery voltage of the power connector is at least 10 Volts.
Correct any known problems, including removing corrosion from the battery
terminals or wiring, or actually replacing the battery if necessary.
Fishing System 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.
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.
