4 Selecting a Transducer Location 1. The transducer must be placed in a location that has a smooth flow of water at all times. If the transducer is to be mounted inside the hull, then the chosen location must be in the water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will s ...

11 Epoxy the transducer to a solid portion of the hull. For example, some (but not all) manufacturers use a layer of fiberglass, then a core of balsa wood, finishing with an outer layer of fiberglass. Removing the inner layer of fibergla ss and the balsa wood core exposes the outer layer of fiberglass. The transducer can then be epoxied directly to ...
