How Sonar Works
Sonar technology is based on sound waves. The 100 SeriesTM Fishing System uses
sonar to locate and define structure, bottom contour and composition, as well as
depth directly below the transducer.
Your 100 SeriesTM 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.

2
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.

Single Beam Sonar
Your 100 Series™ Fishing System uses a 200 kHz
Single Beam sonar system with a 20° area of
coverage. The 20° beam is focused on the bottom,
to show you structure, weeds and cover.
How GPS and Cartography Work
Your 100 SeriesTM Fishing System also supports GPS and chartplotting, and uses GPS and
sonar to determine your position, display it on a grid, and provide detailed underwater
information. The Global Positioning System (GPS) is a satellite navigation system
designed and maintained by the U.S. Department of Defense. GPS was originally
intended for military use; however, civilians may also take advantage of its highly
accurate position capabilities, typically within +/- 10 meters, depending on conditions.
This means that 95% of the time, the GPS receiver will read a location within 10 meters
of your actual position. Your GPS Receiver also uses information from WAAS (the Wide
Area Augmentation System), EGNOS (the European Geostationary Navigation Overlay
Service), and MSAS (the MTSAT Satellite Augmentation System) satellites if they are
available in your area.
3

GPS uses a constellation of 24 satellites that continually
send radio signals to the earth. Your present position is
determined by receiving signals from up to 16 satellites
and measuring the distance from the satellites.
All satellites broadcast a uniquely coded signal once per
second at exactly the same time. 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.
The GPS Receiver included with your 100 SeriesTM Fishing System, allows you to combine
easy-to-useFishingGPSTM chartplotter and navigation capabilitieswith advanced fishfinding.
The following GPS functionality is currently supported by the 100 SeriesTM Fishing System:
• 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.
Your unit also comes with a built-in Uni-MapTM with a more detailed map of North
America (Domestic models) or a more detailed map of Europe and Southeast Asia,
including Australia and New Zealand (International models).
Your 100 SeriesTM uses the GPS Receiver to determine the position of the boat
automatically, and uses the zoom level settings on a particular view to select the best
chart to display. See Viewing Cartography for more information.

What’s On the Display
The 100 SeriesTM can display a variety of useful information about the area under and
Timer - elapsed time with Temp/Speed Accessory
or GPS Receiver.
Depth - water depth; can be set to alarm when the
water becomes too shallow.
Speed - if a Temp/Speed accessory or GPS Receiver
is attached, the 100 SeriesTM 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
Longitude of the cursor position is shown,
be marked at the cursor position for later
Bait Ball

Rocky Bottom
Distance - distance traveled with Temp/Speed
Accessory or 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.
Temperature - water surface temperature.
Average Speed - average speed reading with
Temp/Speed Accessory or GPS Receiver.
Cursor - available in Freeze Frame and can

adjacent to your boat, including the following items:
the display and the depth of the bottom directly below the cursor. In addition, the Latitude and
the distance to travel to the cursor position and the bearing to the cursor position. A waypoint can
retrieval and use.
RTS® (Real Time Sonar) Window
Soft Bottom
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 gray levels
moving across the display at the same depth.
Fish - fish are displayed as arches and/or fish
icons, and the unit can be set to alarm when a
fish of a certain size is detected. When a target is
detected and Fish ID+TM is on, a Fish ID+TM symbol
with depth is displayed. The size of the symbol
shows 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.
200 kHz, Narrow Beam Shaded Fish Symbol
is connected to the 100 SeriesTM Fishing System. If both devices are connected, then only the
be positioned in the Sonar View to provide
below the cursor.
Structure - where fish may be hiding.

Views
The views available on your 100 SeriesTM Fishing System are:
Sonar views: Navigation views:
• Sonar View • Bird’s Eye View
• Zoom View • Chart View
• Big Digits View • Combo View.
• Circular Flasher View.
NOTE: When you change any menu settings that affect the sonar, the view will update
immediately (i.e. you don’t have to exit the menu to apply the change to the screen). For
instance, by switching between "Inverse" and "Structure ID®" from the X-PressTM menu, it is
possible to quickly alternate between the two viewing methods.
Sonar View is the default view. When the VIEW key is pressed, the display cycles
through the available views. When the EXIT key is pressed, the display cycles through
the available views in reverse order. Any view can be hidden or displayed as part of the
view rotation using the Views Menu tab.

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

Understanding Sonar History
It is important to understand the significance of
the 100 SeriesTM Fishing System 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
AReal 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 grayscale.
The grayscale used matches
the bottom view grayscale
setting used in the sonar
history window (i.e. Inverse,
StructureID®, WhiteLine®,
Bottom Black). The depth of
the sonar return is indicated
by the vertical placement of
the return on the display
depth scale.
The Wide RTS® Window in-
dicates 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.

10
Freeze Frame
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 the Sonar and Sonar
Zoom 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.
The sonar returns from the bottom, structure and fish can be represented as either
Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See Sonar X-PressTM
Menu: Bottom View for details on how to set the bottom view.

Inverse is a method where weak returns are shown
with dark pixels and strong returns with lighter
pixels. This has the benefit of ensuring that weak
signals will be clearly visible on the display.
Structure ID® represents weak returns as light pixels
and strong returns as dark pixels. This has the
benefit of ensuring that strong returns will be clearly
visible on the display.
WhiteLine® highlights the strongest sonar returns in
white, resulting in a distinctive outline. This has the
benefit of clearly defining the bottom on the display.
Bottom Black displays all pixels below the bottom
contour as black, regardless of signal strength. This
has the benefit of providing a high contrast between
the bottom and other sonar returns on the display.
Any targets such as fish, structure and thermoclines
will be shown using the Structure ID® method.

12
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-PressTM 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.
