INSTALLATION PREPARATION
INSTALLATION OVERVIEW
display on the control head. It should be installed in contact with the
surface of the water in an area that has smooth water flow - usually on the
transom of the boat. There are several mounting options for the
transducer. Review the following section to determine the method that
works for you and your boat.
Determining How to Mount the Transducer
The 350TX includes a model XT-6-TB-90
transducer. This transducer can be
mounted on the transom of the boat, or
bonded to the inside of a fiberglass hull
boat.
The transom installation, which is the
most widely used, places the transducer
on the outside of the boat hull. This
technique produces the least signal loss,
and provides a way to adjust the
transducer after installation. The
mounting hardware included is designed
to protect both the boat and the
transducer should the boat strike debris
in the water or when trailering.
As an alternative to transom mounting, it is
possible on many fiberglass-hulled
boats to glue the transducer on the
inside of the boat hull. Since
fiberglass has similar sonar character-
istics as water, the sonar signal can
pass through the boat hull with
minimal loss. The hull of the boat
must be single layer construction
(not double-hulled). Also, any air
trapped in the lamination of the
fiberglass would prevent the sonar
signal from passing through.
