Garmin GMI 20 Instrument Display

The Garmin 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 inch colour display with extra large digits is easy to read at a distance and has a 170 degree viewing angle.

A glass bonded lens 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 your having to do a thing. This is especially advantageous to sailors as it allows you to install the unit 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.

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.
