The P79S brings depth intelligence to your boat. Featuring Airmar's Smart Sensor technology, the P79S delivers processed depth data right to the onboard network for multiple displays to use. Smart Sensors have embedded microelectronics—the transducer element and signal processor are only millimeters apart. The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth data is a single cable into a compatible network or display. The Smart Sensor can output in NMEA 0183 or NMEA 2000 protocol.

The P79S includes a plastic mounting base which is aligned to the centerline and secured inside the hull. Then it is filled with non-toxic antifreeze. The transducer is inserted into the base and adjusted for the proper deadrise offset, ensuring the beam will be shooting straight down for maximum echo returns. The eco-friendly coolant provides the best medium to transmit through solid fiberglass and into the surrounding water. The major benefit of an in-hull transducer is no protruding features on the exterior of the hull, making it the perfect choice for trailered or lifted boats. Designed for smaller boats up to 8 m (25') with a solid-fiberglass hull.

P79 NMEA 2000 In-Hull 235 kHz

The P79 in-hull transducer easily adjusts to hull deadrise angles up to 22 °. 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.
