Elevate your sailing with the Garmin gWind Mast Head, a precision wind transducer engineered for accurate wind data in light airs and challenging conditions. Built around twin-fin technology and a three-bladed propeller, it delivers reliable measurements where it counts, so you can sail with confidence.

• Three-bladed propeller for more accurate True Wind Speed (TWS) in lighter air.
• Twin-fin design for a more stable True Wind Angle (TWA).
• Optic reading technology provides superior performance at low wind speeds with excellent linearity.
• GND™ 10 black box bridge enables Nexus Network and compatible Garmin chartplotters to share critical NMEA 2000 data, unlocking seamless cross-compatibility between Nexus sail equipment and Garmin gear.
• Easy plug-and-play installation between Nexus, Garmin chartplotters, NMEA 2000 and USB for quick setup and reliable operation.

The gWind transducer’s twin-fin setup with a 3-bladed propeller keeps measurements efficient and steady, while optic reading delivers outstanding accuracy at low wind speeds and excellent linearity as wind increases. This combination ensures precise wind data from light airs to stronger breezes, translating into smoother sailing performance and better tactical decisions.

Included with the system is the GND™ 10, which bridges Nexus and Garmin devices to share essential NMEA 2000 data, enabling synergistic use of Nexus sail equipment and Garmin chartplotters. For added flexibility, two bundle configurations are available (sold separately).
