c) Place the sonar sensor in a plastic bag full of water and then place it
against the hull bottom.
If depth readings appear as “---” while using one of these methods, toss the sonar sensor
directly into the water to verify that the fish finder is operating properly. If it operates
properly when placed directly in the water, reposition the sensor in a new location in the
hull, and repeat methods a, b, or c. These methods DO NOT work on all hulls and you may
have to place the sensor directly in the water for proper operation.
Note:
The fish finder’s advanced sonar could shoot thru the bottom of a boat or canoe hull.
However, the hull must be made out of solid fiberglass, or a maximum of 1/8” aluminum,
and be in direct contact with the water, with no air pockets. The sonar can not shoot thru
wood, plastic, or any composite material.
3. Mount the sonar sensor to the boat hull.
Find a steel slice which is 1 mm thick at least. Drill holes on it and bend it to
a proper angle. Then use it to mount the sensor to a boat with screws. Please
see the figure.
Note:
The slice should be bent properly so that the sonar sensor is
perpendicular to the water after mounted to the boat.
