gWind™ Wired Wind Sensor
Three-bladed propeller for more accurate True Wind Speed (TWS) in lighter air
Twin-fin design gives a more stable True Wind Angle (TWA)
Optical reading technique for superior performance at low wind speeds with excellent linearity
GND™ 10 black box bridges NMEA 2000® data to Nexus Network and enables Garmin-compatible chartplotters to integrate with Nexus sail equipment and vice versa
Easy plug-and-play installation between Nexus, Garmin chartplotters, NMEA 2000, and USB
The gWind transducer features twin-fin technology with a 3-bladed propeller for more accurate TWS in lighter air, while the twin-fin design gives a more stable TWA. The 3-bladed propeller, unlike a cup design, is always efficient. Combined with optic reading, this transducer provides superior accuracy at low wind speeds and also provides excellent linearity.
The 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. Available in 2 bundles (sold separately).

GDT™ 43 Depth & Temperature Transducer
This thru-hull transducer can read water depth and water temperature. It can retrofit an existing Nexus and Silva 43 mm thru-hull transducer (TH43). When bundled with the NMEA 2000® adapter, the GDT 43 can connect directly to the NMEA 2000 network, and the information can be displayed on a compatible Garmin chartplotter or instrument display. This transducer has a 0-20 degree deadrise.
The GST 43 is a thru-hull transducer that can read water speed and temperature. The transducer can retrofit an existing Nexus 43mm thru-hull transducer (TH43).
Bundled with the GST 10, the GST 43 can connect directly to the NMEA 2000® network, and the information can be displayed on a compatible Garmin chartplotter or instrument display.
In The Box:
2 GMI™ 40 marine instruments (two if that version is selected)
gWind™ wired wind sensor
GND™ 10 black box bridge
GDT™ 43 mm thru-hull depth and temperature transducer
GST™ 43 mm thru-hull speed and temperature transducer
Field-installable mast cable connector
Mast bracket
Mast cable with female connector (25 m)
