The Garmin GNX Wireless Sail Pack 43 is a complete sailing instrument bundle engineered around 43 mm thru-hull fittings, making it a clean drop-in upgrade for any vessel already running Nexus TH43 transducers — no new hull penetrations needed. Wind, speed, depth, and temperature data flow across a plug-and-play NMEA 2000 backbone shared with compatible Garmin chartplotters, while the gWind Wireless 2 masthead transducer cuts mast wiring runs entirely on spars up to 50 feet tall.

Specifications:

• Bundle includes: GNX Wind instrument, GNX 20 marine instrument, gWind Wireless 2 masthead transducer, GDT 43 thru-hull depth transducer, and GST 43 thru-hull speed and temperature transducer
• Transducer fittings: 43 mm thru-hull; direct replacement for existing Nexus TH43 installations with no additional hull drilling required
• Network: NMEA 2000 plug-and-play integration; each transducer includes an adapter for data sharing with compatible Garmin chartplotters and instrument displays
• GNX Wind display: glass-bonded backlit monochrome LCD with customizable backlight colors; simultaneously shows 2 data fields plus a digital wind rose
• GNX Wind data parameters: true and apparent wind, steering guidance, boat speed, and 15+ marine parameters covering wind, speed, and navigation
