The Airmar ST800PV-N2 is a thru-hull Smart™ Sensor that processes speed and water temperature data digitally within the housing itself, then delivers that data via NMEA 2000 or NMEA 0183 analog output to chart plotters, radar displays, or digital readouts. Its low-profile design protrudes just 5 mm (3/16") beyond the hull surface to keep drag to a minimum. The retractable insert and built-in water valve allow for removal without hauling the vessel, and the sensor is available in either a plastic (P120) or bronze (B120) thru-hull housing to suit different hull materials.
