Inside the Hull Transducer Installation
In-hull mounting generally produce s good results in single-thic kness 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.
WARNING! 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.
NOTE: In-hull mounting requires an installed and operational depth sounder.
1. Locating the Transducer Mounting Position
Decide where to install the transducer on the inside of the hull. Consider the following to find the best location:
•Observe the outside of the boat hull to find the areas that are mostly free from turbulent water. Avoid ribs, strakes and other protrusions, as these create turbulence.
•As a general rule, the faster the boat can travel, the further aft and closer to the centerlineof the hull the transducer has to be located in order to remain in contact with the water at high speeds.
