You must install the sonar module in a location with adequate
ventilation where it will not be exposed to extreme
You should mount the transducer in a location where it will
not be jarred when launching, hauling, or storing.
You should mount the transducer in a location where it is not
behind strakes, struts, fittings, water intake or discharge
ports, thru-hull transducers, or anything that creates air
bubbles or causes the water to become turbulent. Turbulent
water may interfere with the sonar beam.
You should mount the transducer as close to the center line
of the boat as possible.

greater deadrise can cause the boat hull to interfere with
the sonar beam , and can cause inconsistent detection on
the opposite side of the boat

in the path of the propeller.
On twin-drive vessels, you should mount the transducer
between the drives, if possible.
You should mount the sonar module in a location where the
LEDs are visible, where the cables can be connected, and
where the device will not be submerged.

Cable Considerations

the cable, or cause cable fatigue due to repeated rotation of the
You should use black electrical tape to secure the cables above
and below the rotating joint. If you secure the cables with zip
ties, do not over-tighten the zip ties.
You should secure the cables above and below the pivot joint of
your trolling motor.
You should create a service loop at least 25 cm (10 in.) long in
the cables, with the rotating joint centered on the loop.
You should use the included tool, a flathead screwdriver, or a
blunt knife to separate the cables.
