Inside the Hull Transducer Installation
In-hull mounting generally produces good results in single thickness fiberglass-
hulled boats. Humminbird® cannot guarantee depth performance when
transmitting and receiving through the hull of the boat, since some signal loss
occurs. The amount of loss depends on hull construction and thickness, as well
as the installation position and process.
NOTE: In-hull mounting requires an installed and operational control head.
NOTE: The integral temperature probe will not work with in-hull mounting, so you
may either want to consider purchasing a Temp Sensor or obtaining a different
transducer. Humminbird® offers a transducer exchange program to swap the NEW
and UNASSEMBLED transducer, accompanied by mounting hardware, for one
without an integral temperature probe. Call the Humminbird® Customer Resource
Center at 1-800-633-1468 for details, or visit www.humminbird.com for more
information.
This installation requires slow-cure two-part epoxy. Do not use silicone or
any other soft adhesive to install the transducer, as this material reduces
the sensitivity of the unit. Do not use five-minute epoxy, as it has a
tendency to cure before all the air bubbles can be purged, thus reducing
signal strength.
