ARNING! Do not touch an active transducer during operation, as this may cause
physical discomfort and may result in personal injury in the form of tissue damage. Handle
the transducer only when the power to the fishfinder is off.
ARNING! This device should not be used as a navigational aid to prevent collision,
grounding, boat damage, or personal injury. When the boat is moving, water depth may
change too quickly to allow time for you to react. Always operate the boat at very slow
speeds if you suspect shallow water or submerged objects.
ARNING! Disassembly and repair of this electronic unit should only be performed by
authorized service personnel. Any modification of the serial number or attempt to repair
the original equipment or accessories by unauthorized individuals will void the warranty.
Handling and/or opening this unit may result in exposure to lead, in the form of solder.
ARNING! This product contains lead, a chemical known to the state of California to
cause cancer, birth defects and other reproductive harm.
The WEEE Directive aims to minimize the impact of end-of-life electrical and electronic
equipment on human health and the environment. Therefore, any product bearing the
WEEE symbol must not be included with unsorted municipal waste. Instead, it must be
separately collected, treated and recycled.
For proper disposal of this equipment, please contact the Johnson Outdoors distributor or see

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.

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.

INSTALLATION O ER IEW
Before you start installation, we encourage you to read these instructions carefully
in order to get the full benefit from your ICE Flasher Series™ Fishfinder. You will
assemble your control head first, then assemble and install your transducer. When
you are done with both of these installation tasks, you should perform a final
installation test before operating your ICE Flasher Series™ Fishfinder.
Please make sure that the following parts are included for your ICE Flasher Series™
control head:
• ICE Flasher Series™ control head
• Portable base and handle
• Power cable, battery, battery charger, and connecting hardware
• Flasher Bag (ICE 55 only)
Also, please make sure the following parts are included for your transducer:
• Ice Fishing transducer with 8' of signal cable
• Float, 40" of support cable, and support clip
• Cable clamps.
In addition to the hardware supplied, you will need a Phillips-head and a flat-head
screwdriver for installation and operation.

ICE FLASHER SERIES™ BASE ASSEMBLY
Perform the following high-level steps by following the instructions in each numbered
section to assemble the ICE Flasher Series™ base assembly:
1. Assembling the transducer storage posts
2. Assembling the base and handle
3. Assembling the control head to the base and handle
1. Assembling the Transducer Storage Posts
In this procedure you will install the posts to hold the transducer cable.
1. Slide one spring over each flat-head screw and set aside.
2. Insert a nut into the keyed space of each cable retention arm. Push down on the
nut until it is flush with the surface of the cable retention arm.
3. Slide one cable retention arm over one storage post so that the arm faces out.
4. old the cable retention arm in place, and turn the base upside down.
5. Drop the assembled screw and spring straight into the back of the storage post.
Using a flat-head screwdriver, push down on the screw, and tighten.
6. Repeat steps 2-5 for the second cable retention arm.
