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"" 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(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.

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.
