from.
A Through-hull transducer, is the type of the transducer that is mounted on the bottom of the vessel
with the directional 90 degrees beam shaped in a cone pattern.
Through-hull transducers are mounted through a hole drilled in the bottom of the boat and protrude
directly into the water. This type of transducer generally provides the best performance for moving
vessels.
