Thru a Boat Hull
The Unit advanced sonar capabilities allows it to
“shoot thru” the bottom of a boat or canoe.
The hull must be made out of solid fiberglass, or
a maximum of 1/8” (3.1 mm) aluminum, and be
in direct contact with the water, with no air
pockets. The unit will not work thru wood, plastic,
or any composite material.
a) place the transducer in 5 inches (13 mm) of
water against the hull bottom.
b) coat the face of the transducer with petroleum
jelly and press it against the hull bottom with a
twisting motion.
c) place the transducer in a plastic bag that is
full of water and place against the hull bottom.
NOTE:
If depth readings appear as " ---" while using
one of these methods, place the sonar sensor
directly in the water to
verify
that the fish finder
is operating properly.
If it operates properly while directly in the water,
reposition the sensor in a new location in the
hull, if it still doesn't work on all hulls and you
may have to place the sensor directly in the
water for proper operation.
