INSTALLATION PREPARATION
INSTALLATION OVERVIEW
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 105SX includes a model XHS- 6-24 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.
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 characteristics 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.
Inside the hull installations require
no holes be drilled into the boat and
through experimentation, high-
speed operation comparable to
transom mounting can be achieved.
Two part, slow cure epoxy (not
included) is required to glue the
transducer in place.
