Power On the Unit
How Sonar Works
Sonar technology is based on sound waves. The 500 Series™ Fishfinder uses
sonar to locate and define structure, bottom contour and composition, as well
as depth directly below the transducer.
Your 500 Series™ Fishfinder sends a sound wave signal and determines
distance by measuring the time between the transmission of the sound wave
and when the sound wave is reflected off of an object; it then uses the reflected
signal to interpret location, size, and composition of an object.
Sonar is very fast. A sound wave can travel from the surface to a depth of
240 ft (70 m) and back again in less than 1/4 of a second. It is unlikely that your
boat can “outrun“ this sonar signal.
SONAR is an acronym for SOund and
NAvigation Ranging. Sonar 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.
How Sonar Works
2
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.

How Sonar Works
DualBeam PLUS™ Sonar
(DualBeam PLUS™ models only
[587ci HD, 597ci HD])
Your 587ci HD/597ci HD Fishfinder 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 sideby-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.

45°
800kHz
(Down Imaging™ models only
[597ci HD DI, XNT 9-DI-T Transducer])
Your 597ci HD DI Fishfinder uses Down
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
Down Imaging™ X-Press™ Menu:
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.
5
How Sonar Works
Ice transducer
Dual Beam Ice Transducer
(optional-purchase XI 9 20 Ice Transducer only)
Your Fishfinder supports the optionalpurchase XI 9 20 Ice Transducer which
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.
How Sonar Works
6
How GPS Works
Your 500 Series™ Fishfinder also supports GPS (Global Positioning System) and
chartplotting. It uses GPS and sonar to determine your position, display it on a
grid, and provide detailed underwater information.
GPS uses a constellation of satellites that
continually send radio signals to the earth. The
GPS receiver on your boat receives signals from
satellites that are visible to it. Based on time
differences between each received signal, the GPS
receiver determines its distance to each satellite.
With distances known, the GPS receiver
mathematically triangulates its own position. With
once per second updates, the GPS receiver then
calculates its velocity and bearing.
GPS was originally intended for military use; however, civilians may also take
advantage of its highly accurate position capabilities, typically within +/- 4.5
meters, depending on conditions. This means that 95% of the time, the GPS
receiver will read a location within 4.5 meters of your actual position. Your GPS
Receiver also uses information from WAAS (the Wide Area Augmentation
System), EGNOS (the European Geostationary Navigation Overlay Service), and
MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.
The following GPS functionality is currently supported by the 500 Series™
Fishfinder when it is connected to the included GPS receiver:
• View current position
• View current track (breadcrumb trail)
• View precision speed and heading from your GPS receiver
• Save tracks, waypoints, and routes
• Travel a route and navigate from one waypoint to the next
See Chart View and Introduction to Navigation: Add Maps to Your Fishfinder
for more information.

How GPS Works
What’s on the Sonar Display
The 500 Series™ Fishfinder can display a variety of useful information about the
Depth - (water depth) can be set to alarm when
the water becomes too shallow.
Temperature - Water surface temperature.
Timer - Elapsed time with Temp/Speed
Accessory or GPS Receiver.
Distance - Distance traveled with Temp/Speed
Accessory or GPS Receiver.
Average Speed - Average speed reading with
Temp/Speed Accessory or GPS Receiver.
Speed - If a GPS Receiver or Temp/Speed
accessory is connected, the Fishfinder can
display the speed of the boat and can keep a
Triplog of nautical or statute miles traveled.
Second Sonar Return - When the sonar signal
bounces between the bottom and the surface of the
water and back again. Use the appearance of the
second return to determine bottom hardness. Hard
bottoms will show a strong second return, while soft
bottoms will show a very weak one or none at all.
Cursor Dialog Box - Indicates cursor depth on
the display and the depth of the bottom directly
below the cursor. The Latitude and Longitude of
the cursor position, the distance to travel to the
cursor position, and the bearing to the cursor
position is shown with a GPS receiver. A
waypoint can be marked at the cursor position
for later retrieval and use with a GPS receiver.
NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either device
information from the GPS receiver will be displayed on the view.
What’s on the Sonar Display

High Sonar Intensity Return
Bait Ball
Cursor - Available in Freeze Frame and can
be positioned in the Sonar View to provide
depth of a sonar return and bottom depth below
the cursor.
Fish - The Fishfinder displays fish as arches
and/or fish icons, and can be set to alarm
when a fish of a certain size is detected.
When a target is detected, a Fish ID+™
symbol appears on the display with the
depth displayed above it. The size of the
symbol indicates the intensity of the sonar
return. The unit will clearly show schools of
Bait Fish as "clouds" of different shapes and
sizes, depending on the number of fish and
boat speed.
Thermoclines - Layers of water with different
temperatures that appear at different depths
and different times of the year. A thermocline
typically appears as a continuous band of
many colors moving across the display at the
same depth.
RTS (Real Time Sonar) Window™
Structure - Where fish may be hiding.
Low Sonar Intensity Return

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 3dimensional 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
placement of the return on the
display depth scale.
What’s on the Sonar Display
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.

SwitchFire™
SwitchFire™ controls how the sonar returns are displayed in the Sonar Views.
SwitchFire™ settings are available in the Sonar Menu Tab.
To see the maximum sonar information available within the transducer beam so
more fish arches and better jig tracking are shown, choose Max Mode.
To see less clutter and more fish size accuracy interpreted from the transducer
beam, choose Clear Mode. See Sonar Menu Tab: SwitchFire™ for more
information.
Freeze Frame and Active Cursor
Freeze Frame and Active Cursor - Press any arrow on the 4-WAY Cursor Control
key, and the screen will freeze and a cursor will be displayed. Use the 4-WAY
Cursor Control key to move the cursor over a sonar return, and the depth of the
sonar return will be displayed at the bottom of the screen in the cursor dialog box.
The RTS Window™ continues to update in Freeze Frame. To return to a scrolling
display and exit Freeze Frame, press the EXIT key. Freeze Frame is available in
the Sonar, Split Sonar, and Sonar Zoom Views.
Instant Image Update
Instant Image Update - You can change a variety of sonar menu settings (such
as Sensitivity or Upper Range), and the adjustments will be shown instantly on
the screen.

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.

The sonar returns from the bottom, structure, and fish can be represented as
either WhiteLine™ or Structure ID®. See Sonar Menu Tab: Bottom View for
details on how to set the bottom view.

Structure ID® represents weak returns in blue and strong returns in red.
WhiteLine™ highlights the strongest sonar returns in white, resulting in a
distinctive outline. This has the benefit of clearly defining the bottom on the display.

What’s on the Down Imaging™ Display
Down Imaging™ uses its unique transducer and sonar technology to provide
definition profiling beams produce the detailed sonar data that you see on the
can interpret the structure and bottom contour, including the following items:
Depth - (water depth) can be set to alarm when
the water becomes too shallow.
Temperature - Water surface temperature.
Bottom Return- Use the appearance of the bottom
return to determine bottom hardness. Rock and
gravel provide a clearer sonar return than
mud and sand because hard objects reflect
sonar better than soft objects.
Topography Changes - The light part of the
display shows where the beam is hitting hard
bottom or rising terrain. The dark part of the
display indicates soft bottom (sand, mud) or
descending terrain.
Speed - If a GPS Receiver or Temp/Speed
accessory is connected, the Fishfinder can
display the speed of the boat and can keep a
Triplog of nautical or statute miles traveled.
NOTE: Entries in this view that list (with Temp/Speed or GPS Receiver) are available if either
the information from the GPS receiver will be displayed on the view.

Upper Range
Clouded Area may indicate a bait ball and
White Streaks may indicate fish.
Shadows- Result from a lack of reflected sonar
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:
• Dark shades represent soft returns (mud, sand) or descending terrain.
• Light shades represent denser terrain (timber, rocks) or rising terrain. A
very hard bottom may appear as white on the display.
• White Streaks or Clouds may represent fish on the display.
• Shadows are not caused by light but by the lack of a sonar return.
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 Imaging Sensitivity to control how the sonar returns appear on the
display. Increase the sensitivity to reveal weaker returns that may be of interest,
especially in very clear water or greater depths. Decrease the Imaging
Sensitivity to eliminate the clutter from the display that is sometimes present
in murky or muddy water. See Imaging Sensitivity or Down Imaging™
Sensitivity for more information.
Freeze Frame and Active Cursor
Freeze Frame and Active Cursor - Press any arrow on the 4-WAY Cursor Control
key, and the screen will freeze and a cursor will be displayed. Use the 4-WAY
Cursor Control key to move the cursor over a sonar return, and the depth of the
sonar return will be displayed in the cursor dialog box.
Zoom: Use the zoom feature on your control head to see the returns near the
cursor location at a higher magnification. See Views: Down Imaging™ View
for more information.

What’s on the Down Imaging™ Display
Views
The sonar and navigation information from your Fishfinder is
displayed on your screen in a variety of easy-to-read views.
There are many views available on your Fishfinder.
• Default View: When you first power up the 587ci HD/597ci HD control
head, Sonar View will be the default view. When you first power up the
597ci HD DI, the Chart/Down Imaging™ Combo View will be the default
view.
• Cycle: When you press the VIEW key repeatedly, the display cycles
through the available views on your screen. When you press the EXIT
key, the display cycles through the available views in reverse order.
• Customize: You can display or hide any view to suit your fishing
preferences. See the following pages for more information about each
View.
To customize your views rotation:
You can choose which views are hidden or visible in your view rotation.
