The Garmin GNX Wired Sail Pack 43 delivers a complete wired sailing instrument bundle built around 43 mm thru-hull transducers, making it a clean retrofit for any vessel already fitted with Nexus or Silva TH43 hardware — no additional hull penetrations required. The pack includes the GNX Wind instrument, GNX 20 display, gWind Wired transducer, GDT 43 depth transducer, and GST 43 speed/temperature transducer, all networked over NMEA 2000 for seamless integration with compatible Garmin chartplotters and instruments.

GNX Wind Instrument

A glass-bonded backlit monochrome LCD presents two simultaneous data fields alongside a digital wind rose, covering true and apparent wind, steering guidance, boat speed, and more than 15 marine parameters. Backlight color is user-configurable. ANT connectivity links the instrument directly to the gWind Wired transducer and extends compatibility to a quatix GPS marine smartwatch or Garmin Nautix in-view display for live wind data streaming.

gWind Wired Transducer

Nexus twin-fin technology paired with a 3-bladed propeller ensures accurate wind speed measurement and stable True Wind Angle (TWA) even in light-air conditions. Wind data transmits via ANT directly to the GNX Wind instrument or a compatible GPSMAP chartplotter.

GNX 20 Marine Instrument

A glass-bonded display with anti-glare lens coating presents high-contrast digits scalable to 36 mm, remaining readable in both bright sunlight and low-light conditions. The GNX 20 displays water depth, boat speed through water, water temperature, and more than 50 marine and boat parameters over the NMEA 2000 network. Five display configurations — single, dual, triple function, gauge, and graph modes — support both sailboat and powerboat profiles with fully customizable page layouts.

GDT 43 and GST 43 Transducers

Both transducers use 43 mm thru-hull fittings for direct replacement of existing Nexus or Silva TH43 hardware. The GST 43 measures speed and temperature; the GDT 43 measures depth. Each GDT 43 ships with an NMEA 2000 adapter so depth data is immediately available across the network to compatible Garmin chartplotters and displays.
