The P39 is Airmar’s mid-size, transom-mount TRIDUCER® Multisensor that combines depth, speed, and temperature functions in one compact housing. Its hydrodynamic design, featuring a rounded nose, reduces turbulence beneath the acoustic face to deliver accurate depth readings even at high speeds. Airmar’s Smart™ Sensors have integrated microelectronics, with signal processing occurring right inside the housing, just millimeters from the transducer element. This allows for precise data transmission through a single cable connected to a compatible network or display. The P39 is available as either an analog sensor or a digital Smart Sensor with output in NMEA 0183 or NMEA 2000® protocol.
