The Garmin P79 is an in-hull smart transducer designed to deliver depth data directly to a NMEA 2000 network — no fishfinder head unit required for basic sonar output. A 235 kHz operating frequency and narrow 11° beamwidth provide focused bottom readings, and the transducer handles hull deadrise angles up to 22°, making it a practical fit for a wide range of monohull vessels.
