The Garmin GMI™/GNX™ Wired Sail Pack 52 delivers a complete wired instrument system for sailors who need reliable, real-time wind and water data. The bundle combines the GMI™ 20 color display instrument, GNX™ 20 monochrome instrument, gWind™ wired transducer, and Airmar DST810 thru-hull smart transducer — covering depth, speed, temperature, wind angle, wind speed, and vessel attitude across a single NMEA 2000® network.

GMI 20 Marine Instrument

The GMI 20 centers on a 4-inch color glass-bonded lens with an anti-glare finish that prevents fogging and enhances contrast. Three selectable night modes — red/black, green/black, and standard night — pair with dimmer control and a 170-degree viewing angle for around-the-clock readability. Over 100 marine and vessel parameters display in extra-large digits, and auto-scroll pages allow flexible mounting positions throughout the vessel. Default profiles include powerboat, sailboat, fishing, engine/fuel, and user-defined configurations, all powered directly from the NMEA 2000® network.

GNX 20 Marine Instrument

The GNX 20 uses a glass-bonded monochrome LCD with an anti-glare coating, presenting black digits on a white or color background. Digits scale up to 36 mm for clear day and night readability, with access to water depth, boat speed through water, water temperature, and more than 50 marine and vessel parameters.

gWind Wired Transducer

The gWind transducer combines a 3-bladed propeller with a twin-fin design and optical reading technology. Unlike a cup-style anemometer, the propeller geometry sustains efficiency across all rotational speeds, yielding superior accuracy at low wind speeds and strong linearity. The twin-fin layout produces a more stable True Wind Angle (TWA), while the 3-bladed propeller improves True Wind Speed (TWS) accuracy in light air.

Airmar DST810 Thru-Hull Smart Transducer

The DST810 is a multisensor thru-hull transducer that outputs depth, speed, and water temperature data along with attitude sensing for heel/trim and pitch/roll — all transmitted over the NMEA 2000® network. Maximum readable depth reaches 330 feet, water speed signal output runs at 5 Hz, and the operating frequency is 235 kHz with a fan-shaped 10×44-degree beamwidth. Bluetooth® connectivity enables DST810 calibration via Airmar's Cast app, and advanced speed calibration accommodates multiple heel angles and speeds.
