The P79 is an in-hull depth transducer. The active element mounts in a small round tank (included) which is epoxied to the hull and filled with non-toxic antifreeze. This transducer is for use with solid fiberglass hulls only. Cored hulls will impede the signal. The P79 cannot measure water temperature.

The P79 is shipped as a generic 'Mix and Match' transducer plus a brand-specific adapter cable. If you change fishfinder brands in the future, you can continue to use the transducer with a new adapter cable.

This FISO version of the transducer is for ST40 and ST60 instruments.
