|The P79 is a 50/200kHz fishfinder transducer that mounts inside a hull - no hole is needed in the hull. The active element mounts in a small round tank (included) which is epoxied to the hull and filled with antifreeze. This transducer is for use with solid fiberglass hulls only. Cored hulls will impede the signal. This unit cannot measure water temperature.
This item consists of the P79 transducer with a fixed 6M NMEA 2000 drop cable ending in a standard NMEA 2000 male connector.
Although most P79s are now made as a generic 'mix and match' (MM) transducer with a brand-specific adapter cable, this unit has a different internal circuitry and a permanent fixed 6M cable and cannot be used with MM adapters.
