Please refer to the following table to help you identify and correct some of the
common troubleshooting scenarios we encounter.
Problem
Possible Cause
Solution
Display won’t
turn on
The 1-amp in-line fuse is
broken
Replace the 1-amp fuse found near the end
of the power cord
No probe data
appears on the
display
The probe is out of the water
The batteries in the probe
are dead
The transducer is not placed
correctly on the transom
The Gain adjustment is set
too low
The probe is too close to the
boat
The probe is only on when in the water
Replace with fresh alkaline AA batteries
Locate the transducer in a spot on the tran-
som where bubbles are minimized. Do not
locate the transducer near a kicker motor.
Make sure the transducer face is level with
the water’s
Press the SET button on the display. The
default setting is 15, use the arrow up key
to increase the gain. The Gain may need to
be set higher in water deeper than 150’ or
with cannon balls
The probe needs to be at least 5-feet under
the transducer
The probe
temperature on
the display reads
3.8 - 4.0
The thermistor tubes on the
probe have been damaged
To prevent this from ever happening,
remove the probe from the downrigger
cable when not in use, or secure the probe
tightly to the downrigger with a bungee.
Unfortunately there is no way to repair the
damage, the probe must be replaced.
Probe numbers
on the display are
erratic
Sonar interference from a
50 or 83 KHz transducer lo-
cated next to the Fish Hawk
transducer (70 KHz) on the
transom.
The fastest way to eliminate this is to turn
off the 50 KHz or 83 KHz beam on your
fish finder ad. You can also try reducing
the Gain setting on the Fish Hawk display
by pressing the SET button and then the
arrow down key, or separating transducer
cables if tied together. The permanent
solution is relocating the transducer away
from other 50 or 83 KHz transducers on
the transom.
Surface and
probe numbers
on the display are
erratic
Electrical interference from
the boat
Run the Fish Hawk display power cord di-
rectly to the boat battery and not through
a fuse panel
The Fish Hawk
display turns on
or off when you
start the engine.
There is an open ground in
the power system
Replace the standard spark plugs with
resistor value spark plugs
