hull materials, including alu-
minum. However, the trans-
ducer is not easily removed
after installation.
Finding the best location
for the transducer before
installation is critical. Choose
a flat smooth spot near the
center of the hull 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 at all speeds. When the boat is
in the water, put about a half inch of water in the bottom
of the boat and hold the transducer in the intended
location. Move the transducer around until you get the best
reading. Mark the spot.
To install the transducer, first 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 inside of 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. It is important that you let the glue dry completely
before turning the unit on.
* If your hull is aluminum, use silicone. This material will flex with
the hull at high speeds and in rough water.
