Garmin GMI & GNX 20 Wired Sail Pack 52 - 0100124890


With a GMI/GNX Wired Sail Pack 52, you’ll have all the equipment you need to know what’s going on with the wind and water.

GMI 20 marine instrument

The GMI 20 digital marine instrument display is perfectly designed for both power and sail. Designed to clearly show depth, speed, wind and 100-plus marine and vessel parameters, its large, bright 4-inch colour display with extra-large digits is easy to read at a distance and 170-degree viewing angle.

A glass-bonded finish lens on GMI 20 prevents fogging and increases contrast. Daylight readability is enhanced with a high-contrast colour scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode colour scheme along with a dimmer control. Screens can be set to auto-scroll — cycling between pages automatically without you having to do a thing. This is especially advantageous for sailors as it allows you to install the unit(s) in a greater variety of locations on the vessel. Default profiles can be customised for powerboat, sailboat, fishing, engine/fuel plus several other user-specified profiles. Power is supplied by the NMEA 2000® network.

gWind transducer

gWind transducer features twin-fin technology with 3-bladed propeller for more accurate True Wind Speed (TWS) in lighter air while the twin-fin design gives a more stable True Wind Angle (TWA). The 3-bladed propeller, unlike a cups design, is always efficient. Combined with optic reading, this transducer provides superior accuracy at low wind speeds and also provides for excellent linearity.

GNX 20 marine instrument

The easy-to-read GNX 20 marine instrument display with black digits on a white or colour background clearly shows water depth, boat speed through the water, water temperature and 50-plus marine and boat parameters. Its glass-bonded display with anti-glare lens coating provides excellent daytime and night-time readability with high-contrast digits scalable up to 36 mm.

Airmar DST810 thru-hull smart transducer

DST810 combines precise depth, speed and temperature data with attitude sensing for heel/trim and pitch/roll inputs — which it provides to the NMEA 2000® network and GNX 20 instrument. This multisensor transducer can read depths to 330 feet, offers fast 5 Hz water speed signal output and has an operating frequency of 235 kHz with a fan-shaped beamwidth of 10 x 44 degrees. Additionally, wireless connectivity to devices with BLUETOOTH® technology enables DST810 calibration directly through Airmar’s Cast app. Advanced speed calibration allows for calibration at multiple heel angles and speeds.
