PUCK STYLE TRANSDUCERS
There are three ways in which a Puck
Style transducer can be mounted. It can be
mounted In-Hull, on an electric trolling
motor, or portable (with a suction cup or on
an arm of some type).
IN-HULL MOUNTING
This method, gluing the transducer to the hull, gets the same
results as if you were using the High Speed transducer only there are
no holes to drill in the boat and there is no transducer on the transom
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 diameter 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.
