HOW SONAR WORKS
Sonar technology is based on sound waves. The ICE Flasher Series™ Fishfinder uses
sonar to locate structure, bottom composition, as well as depth directly below the
transducer. Your ICE Flasher Series™ Fishfinder consists of two components: the control
head and the transducer. The control head contains the transmitter and receiver, as well
as the user controls and display. The transducer is suspended beneath the water,
underneath the ice, and converts electrical energy from the transmitter into mechanical
pulses or sound waves. The transducer also receives the reflected sound waves and
converts them back into electrical signals for display on the Flasher Dial.
NOTE: The transducer must be submerged in water for reliable transducer detection. The
bottom of the transducer should be even with the bottom of the ice or hang slightly below
the bottom of the ice.
Your ICE Flasher 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
depth, 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.
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, or signals, are displayed as colored
lines on the Flasher Dial.
Real Time Sonar
Instant Display

When all the echoes are viewed within
the beam, an easy to interpret multicolor
palette of sonar return signals appears
on the Flasher Dial. The ICE Flasher
Series™ Fishfinder plots the depth and
intensity of sonar returns from the
bottom, fish and structure.
The sound pulses are transmitted at
various frequencies depending on the
application. Your ICE Flasher Series™
Fishfinder gives you the power to choose
the frequency and coverage of your
sonar. 455 k z provides narrow coverage
with the greatest definition. 240 k z
provides wider coverage and a good
balance between depth performance
and resolution.
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,
and enhanced depth capability.
2

Your ICE Flasher Series™ Fishfinder uses
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 9 degree center beam provides
the highest definition, while the 19 degree beam
provides wider coverage. Depth capability is
affected by such factors as bottom hardness,
water conditions, and transducer installation.
Whether fishing in shallow to very deep water,
in both fresh and salt water, selectable
dual-frequency is ideal for a variety of conditions.

HOW ICE FLASHERS WORK
Although the sonar part of an ICE Flasher Series™ Fishfinder works in the same way as
any other umminbird® control head, the return signal is displayed differently. The ICE
Flasher Series™ LCD is modeled on the original analog displays and represents what is
happening below the transducer the moment it happens. The Flasher Dial displays a
multicolor palette indicating low to high sonar intensity returns, where red indicates high
intensity and green indicates low intensity. See Color Palettes for more information.
When fish swim into the area below the transducer, the new sonar return signal is
immediately displayed on the Flasher Dial. Depending on the size of the fish and its
closeness to the transducer, the sonar return will be displayed as a weak, medium, or
strong sonar signal.
In the above example, the sonar return signal from the jig is displayed as a weak signal
(green), the fish is displayed as a medium signal (yellow), and the bottom composition
is displayed as a strong signal (red). When the fish swims towards your jig, you can see
the activity instantly on your Flasher Dial. Also, the Active Display shows that the ICE
45/55 Flasher is reading the depth of 18.3 feet to the bottom.

Charging usually requires 8 continuous hours but may vary depending on your
configuration. The LED on the charger will turn green when the battery is
fully charged.
NOTE: Some international models may not include a battery or battery charger.
NOTE: The battery charger uses a yellow LED to indicate it is charging. On some models,
this light might appear closer to orange than yellow. When this happens, the battery is still
charging properly and should be left to charge until the LED becomes green.
CAUTION: Do not pull on the battery or charger cables when you are trying to connect
them to or disconnect them from the battery terminals. Push or pull gently on the spade
terminals instead. If the connector feels tight, use a slight wiggling motion to slide the
spade connector into place on the terminal.

TRANSDUCER INSTALLATION
Perform the following high-level steps by following the instructions in each numbered
section to install the transducer.
1. Testing the transducer
2. Assembling the transducer and float
3. Connecting the cable
1. Testing the Transducer Prior to Installation
Prior to installation, test the transducer to make sure that no damage occurred during
shipping.
1. Connect the transducer to the control head. The slots are keyed to prevent reverse
installation, so be careful not to force the connector into the holder.
2. Drop the transducer into the ice hole. If the transducer is working properly, you
will see the bottom displayed on the Flasher Dial as a red line.
WARNING: Before walking onto the ice, make sure that conditions are safe.
2. Assembling the Transducer and Float
In this procedure you will assemble the transducer and float.
1. Thread the support cable through
the support clip and then clip onto
the transducer.
2. Attach your transducer float to the
support cable by sliding the support
cable through the slit in the float.
NOTE: Attaching the float is optional. You
can also use the storage posts to hold the
support cable in position.

3. Position the float so that the transducer will be submerged in the water, just
below the ice.
NOTE: The transducer must be submerged in water for reliable transducer detection. The
bottom of the transducer should be even with the bottom of the ice or hang slightly below the
bottom of the ice.
4. Once you know where you want to
position your float, place one of the cable
clamps onto the support cable, above the
float. Use the inside, smaller cable hole
for the support cable so that the float will
not move, and so that the transducer will
maintain its position under the ice. Make
sure that the support cable is taut, so that
the transducer hangs straight down (see
illustration).
5. If you would like to keep the support and
signal cables together above the float
stop, attach a cable management clamp
(included) to the support cable (using
the inner, smaller hole) and the signal
cable (using the outer, larger hole).
Make sure that the signal cable has
some slack so that it is not bearing the
weight of the transducer.

NOTE: If you have an ICE 55 Flasher, remove the control head and base from the portable
bag first.
1. Insert the transducer cable into the appropriate terminal slot on the rear of the
control head.
NOTE: The slots are keyed to prevent reversed installation, so be careful not to force the
connector onto the holder.
2. Route the transducer signal cable beneath the control head and secure to cable
clips on the base.
3. Reinstall assembled control head, base, and transducer into portable bag
(ICE 55 only).

TEST AND FINISH THE INSTALLATION
Once you have assembled both the ICE Flasher Series™ control head and the Ice Fishing
transducer, and have routed all the cables, you should perform a final test. Testing
should be performed with the transducer in the water.
1. After connecting the transducer to the control head, and confirming that the
power cable is connected to the battery, drop the transducer into the ice hole to
confirm proper operation.
WARNING: Before walking onto the ice, make sure that conditions are safe.
2. Turn the Power/Range dial to A (Auto) or x1 to power-on the control head.
NOTE: If the unit does not power up, make sure that the connector is fully seated in the
back of the control head, the power cable is connected to the battery, and the battery is
charged.
3. If all connections are correct and power is available, the umminbird® control
head will enter Normal operation, and you should see the bottom on the control
head display.
4. If the bottom is visible on-screen with a digital depth readout, the unit is working
properly (ICE 35 will only display the bottom on the Flasher Dial).
NOTE: The transducer must be submerged in water for reliable transducer detection. The
bottom of the transducer should be even with the bottom of the ice or hang slightly below
the bottom of the ice.
