How Sonar Works
How Sonar Works
Sonar technology is based on sound waves. The 600 Series™ Fishfinder uses
sonar to locate and define structure, bottom contour and composition, as well
as depth directly below the transducer.
Your 600 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 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.
3
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 [678c HD])™
Your uses a 200/83 kHz678c HD Fishfinder
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.
How Sonar Works
Down Imaging® Sonar
(Down Imaging models only®
[678c HD DI, XNT 9-DI-T Transducer])
Your uses Down678c HD DI Fishfinder
Imaging® technology. The Down Imaging®
transducer scans the water with razor-thin,
high-definition beams. The beams are wide
(side to side) but very thin front to back.
The Down Imaging® beams can be
operated at two frequencies: 455 kHz (75°)
or 800 kHz (45°). Select 455 kHz for the
best overall image quality and depth.
Select 800 kHz for the sharpest image. See
Sonar Menu Tab: Imaging Frequency for
more information.
The transducer also uses conical beams to
provide data in traditional 2D format (see
What’s on the Sonar View). Select 455 kHz for
a narrowly focused 16° center beam, or select
200 kHz for a wider 25° beam (see Sonar
Menu Tab: Beam Select).
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 [678c HD XD])
Your uses the XD678c HD XD Fishfinder
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 Viewsand for more
information).
Depth capability is affected by such factors as
boat speed, wave action, bottom hardness,
water conditions and transducer installation.
How Sonar Works

Dual Beam Ice Transducer
(optional-purchase XI 9 20 Ice Transducer only)
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° center beam provides the highest
definition, while the 60° beam provides wider
coverage. Depth capability is affected by such
factors as bottom hardness and water
conditions. Whether fishing in shallow or very
deep water, selectable dual-frequency is ideal
for a variety of conditions.

boat speed.
14
What’s on the Sonar Display
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
AReal 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
placement ofthe 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 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
scale. The Wide RTS
Window does not use™
grayscale.
.
15 What’s on the Sonar Display
Sonar Colors and Bottom View
As the boat moves, the unit charts the changes
in depth on the display to create a profile of the
Bottom Contour. The Sonar View displays the
sonar return intensity with different colors.
Strong returns often result from rocky or hard
bottoms (compacted sediment, rocks, fallen
trees), while weaker returns often result from
soft bottoms (sand, mud), vegetation, and small
fish.
The colors used to represent high, medium, to
low intensity returns are determined by the
palette you choose in the menuSonar Colors
option. See Sonar Menu Tab to set the Sonar
Colors.

from a particular area and can be as valuable
for interpretation than the sonar reflected by
the object itself. Use shadows to help you see
the image in 3 dimensions, oriented in space.
You can gain insight into the actual shape of
an object, or the depth to which it has sunk
into the bottom, through shadows on the
display. Objects standing on the bottom cast
a sonar shadow. The longer the shadow, the
taller the object. Fish also cast shadows. You
can use the shadow to interpret how close
the fish is to the bottom.

Understanding the Down Imaging® Display
The images you see on the Down Imaging® display
are produced using sonar technology. Each time the
unit pings, a strip of data representing all the
echoes received by the transducer are put together
on the display to form the image that you see. Like
traditional 2D Sonar, the sonar history scrolls left
across the screen.
Interpreting the Display
Down Imaging® beams “illuminate” the bottom contour, structure, and fish.
The beams are wide (side to side) but very thin front to back.
Use the light and dark parts of the display to interpret the objects under your
boat as follows:
• represent soft returns (mud, sand) or descending terrain.Dark shades
• represent denser terrain (timber, rocks) or rising terrain. ALight shades
very hard bottom may appear as on the display.white
•White Streaks Cloudsor may represent fish on the display.
• are not caused by light but by the lack of a sonar return.Shadows
Objects standing on the bottom cause a sonar shadow to appear on the
display. The longer the shadow, the taller the object. Fish may also cast
shadows. You can use the shadow to interpret where the fish or object
is located in relation to the bottom.

Down Imaging® Sensitivity
Use to control how the sonar returns appear on the display.Down Sensitivity
Increase the sensitivity to reveal weaker returns that may be of interest,
especially in very clear water or greater depths. Decrease the sensitivity to
eliminate the clutter from the display that is sometimes present in murky or
muddy water. See Down Imaging® X-Press™ Menu: Down Sensitivity for
more information.

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:
•678c HD: 0 to 1490 ft, 0 to 454 m (International Models only); Default = 0
•678c HD DI: 0 to 590 ft, 0 to 180 m (International Models only); Default = 0
• 0 to 2490 ft, 0 to 759 m (International Models only);678c HD XD:
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.
NOTE: A minimum distance of 10 feet will be maintained between the Upper and
Lower Range regardless of the manual settings entered.
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.
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.

The available Lower Range settings are determined by your Humminbird®
model as follows:
• Auto to 1500 ft, Auto to 457 m (International Models only);678c HD:
Default = Auto
•678c HD DI: Auto to 600 ft, Auto to 183 m (International Models only);

• Auto to 2500 ft, Auto to 762 m (International Models678c HD XD:
only); Default = Auto
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 shows more information and is preferred by most anglersfaster speed
however, the sonar information moves across the display quickly. A slower spee
keeps the information on the display longer, but the bottom and fish details
become compressed and may be difficult to interpret. Regardless of the Char
Speed setting, the RTS Window will update at the maximum rate possible f™
the depth conditions. Adjust Chart Speed to your personal preference.
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 t
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 V

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.
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 feet
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.

Settings: 1 to 20, where Low = 1, High = 20; Default = 10
Down Sensitivity controls how the sonar returns are displayed on the
Down Imaging® Views.
Increase the Down Sensitivity to reveal weaker returns that may be of interest,
especially in very clear water or greater depths. A high sensitivity setting shows
more sonar returns from small baitfish and suspended debris in the water;
however if the sensitivity is adjusted too high, the display may become too
cluttered.
Decrease the Down Sensitivity to eliminate the clutter from the display that is
sometimes present in murky or muddy water. If the sensitivity is adjusted too
low, the display may not show many sonar returns that could be fish.
DI Enhance
Settings: Press the RIGHT Cursor key.
DI Enhance allows you to adjust your Down Imaging® View in the following
categories: Sensitivity, Contrast, and Sharpness.
Whether you’re searching the Down Imaging® data for fish or certain bottom
contour, the most effective settings will vary with the situation. The display will
update as you adjust each category.
•Sensitivity: Controls how much detail is shown on the display. 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. (1 to 20, where Low = 1, High = 20; Default = 10)
NOTE: The Sensitivity can be adjusted from the DI Enhance dialog box or the
Down Imaging® X-Press™ Menu. The Sensitivity setting is provided here so that

Upper Range
(Advanced)
Settings: 0 to 590 ft or 0 to 180 m [International models
only], Default = 0
Upper Range sets the shallowest depth range that will be displayed on the
Down Imaging® Views. Upper Range is often used with Lower Range.
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 to 600 ft, Auto to 183 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.
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.
M
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.

Lower Range regardless of the settings entered manually.
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.
Afaster 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.
DI Colors
Settings: Blue, Amber 1, Amber 2, Brown, Green, Inverse,
Gray, Green/Red; Default = Amber 1
DI Colors allows you to select which color palette you would like to use for the
Down Imaging® display.
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.
