The Garmin gWind Transducer features twin-fin technology with three-bladed propeller for more accurate True Wind Speed (TWS) in lighter air while the twin fin design gives a more stable True Wind Angle (TWA). The three-bladed propeller, unlike a cups design, is always efficient. Combined with optic reading this transducer provides superior accuracy at low wind speeds and also provides for excellent linearity. Included GND 10 black box bridge enables the Nexus Network and compatible Garmin chartplotters to share critical NMEA 2000 data. The GND 10 enables Garmin chartplotter owners to use Nexus sail equipment and vice versa. GND 10 Black Box Bridge The GND 10 black box bridge seamlessly integrates Nexus instruments and sensors with the Garmin family. It converts data between the Nexus Network and NMEA 2000 to provide compatibility between Nexus and Garmin products, including gWindT, gWindT Wireless and gWindT Race transducers. Simple plug-and-play installation between Nexus and NMEA 2000, with USB connectivity, eliminates the need for user setup and system configuration. GND 10 allows PC applications, such as NexusRace, Expedition, Adrena or SeaTrack, to communicate sailing-specific functions between Nexus and NMEA 2000 networks. It also enables GND 10 software updates over NMEA 2000. Existing NexusRace PC application can be used to update software, configure and calibrate Nexus devices over USB using the FDX protocol.
