P79 NMEA 2000 In-Hull 235 kHzThe P79 in-hull transducer easily adjusts to hull deadrise angles up to 22 Adeg. This ensures that the beam is vertically oriented to receive echos, resulting in accurate depth readings. Unlike traditional "puck" type transducers, our P79 consists of a base that is bonded to the hull and filled with liquid. The separate transducer then attaches to the base with a twist lock. The sound waves travel more efficiently though the liquid, giving the best possible performance. The unique adjustable-angle design ensures the beam is vertically oriented for maximum echo returns and the best possible performance. Because the transducer is mounted inside the hull, it is the perfect solution for rigid inflatable boats (RIBS) and racing sailboats.
