Installing the Fishfinder Unit
Selecting a Fishfinder installation Location
Select a Fishfinder installation location that allows you to
view and operate it easily while operating the vessel. Select
a mounting surface strong enough to support the weight
of the Fishfinder and protect it from excessive vibration or
shock. DO NOT mount the bracket in a location where the
Fishfinder is exposed to extreme temperature conditions.
When installing the mounting bracket, be sure to allow
room to connect and rout the power cable.
