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

Set Sail with Ease

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

In addition, the GMI 20 also features a dedicated race timer that counts down and counts up, with an internal beeper. Included are 2 trim snap piece cover options which allow you to match the GMI 20 with the new GPSMAP® 500/700 series, GPSMAP 8000 Glass Helm series or legacy Garmin chartplotters.

Two Options

When selecting your GMI, there are 2 bundled versions to pick from: one includes a GWS™ 10 wind transducer and the other, a DST800 thru-hull smart transducer and GWS 10 transducer. The wind transducer records speed and direction, air temperature and barometric pressure. The thru-hull records water depth, water temperature and boat speed.
