The gWind sensor is equipped with twin fin technology with triple blade propeller, providing more accurate data for true wind speed even in low winds. The twin fin design is responsible for a more stable angle measurement of the true wind. The three-blade propeller is always efficient unlike the usual design. Combined with optimal reading behavior, the sensor delivers superior accuracy at low wind speeds as well as excellent linearity. The included GND 10 blackbox gateway allows you to exchange important NMEA 2000 data between the Nexus network and compatible Garmin chartplotters. Garmin chartplotter owners can use the GND 10 Nexus sailing gear - and vice versa.
