The Garmin gWind Mast Head is a precision wind transducer built for sailors who need reliable wind data across light air to stronger conditions, delivering accurate measurements that integrate directly with existing Nexus sail equipment and Garmin chartplotters.
-
Twin-fin and three-bladed propeller design: Provides stable True Wind Angle readings and improved True Wind Speed accuracy even in light air.
-
Optic reading technology: Ensures strong performance at low wind speeds with consistent linearity as wind strength increases.
-
GND 10 bridge: Enables NMEA 2000 data sharing between Nexus instruments and Garmin chartplotters for full cross-device compatibility.
-
Plug-and-play installation: Connects via NMEA 2000 drop cable, T-connector, 25 m mast cable, and included mast bracket for quick setup with Nexus, Garmin, and USB systems.
-
Measurement range and accuracy: Tracks wind speeds from 0.8 to 90 knots with angle accuracy better than ±1.5° and speed accuracy better than ±3%.
-
Physical and environmental specs: Measures 13.6" x 24" (345 mm x 610 mm), weighs 260 g, includes a 25 m cable, carries an IPX6 waterproof rating, and operates from 5°F to 158°F on 9–16 V with just 0.33 W power draw.
This transducer supplies consistent wind data that supports better tactical decisions on the water while allowing sailors to combine legacy Nexus gear with newer Garmin displays without extensive rewiring or additional converters.
