In-Hull Mounting
This method, gluing the transducer to the hull, gets the same
results as if you were mounting the transducer externally, only there
are no holes to drill in the boat and there is no transducer on the tran-
som to get damaged by impact.
Finding the best location for the transducer before mounting is
critical. Choose a flat smooth spot near the center of the bilge and
near the back of the boat. It is a good idea to make a "test run" before
you permanently install the transducer to make sure that you can
indeed get a reading through your hull, and when the boat is on
plane. Put about a half inch of water in the bilge and hold the trans-
ducer in the intended location. Move the transducer around until you
get the best reading. Mark the spot.
To install the transducer clean the spot of mud and oil. Using an
epoxy or silicone glue make a puddle, about the same size as the
transducer, on the hull. Place the transducer in the glue. Press it
down firmly, gently twisting it back and forth, making sure that there
are no air bubbles in the glue between the transducer and the hull. Let
the glue dry completely before turning the unit on.
Run the transducer cord up to the unit taking the same care as you
did when you ran the power cord. Plug the transducer connector into
the back of the unit and screw the retaining ring down tight.
PORTABLE MOUNTING
An optional suction cup bracket can be used to temporarily attach
a transducer to the transom or side of the boat. The cup should be
placed in a location where it will not be torn off when the boat goes
high speed. It is a good idea to tie on a safety rope in case the cup does
let go. An arm can also be used to hold the transducer. Simply attach
the transducer to the end of the arm using cable ties or tape. Plug the
transducer connector into the back of the unit and screw the retaining
ring down tight.
