A marine instrument display that clearly shows depth, speed, wind and over 100 other marine and vessel parameters on a large, bright 4" colour glass-bonded lens display with an anti-glare finish.

GMI20's glass-bonded lens prevents fogging and increases contrast. A high contrast colour scheme enhances daylight readability - whilst a choice of red/black, green/black or a normal night mode colour scheme enhances visibility at night. There's also a dimmer control to further increase night-time readability. The extra large digits are easy to read at a distance, and the display has a 170 degree viewing angle.

The screen can be set to auto-scroll, cycling between pages automatically without you having to do a thing. This is a huge advantage as it allows you to install a number of units in a greater variety of locations on your 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.

GM20 also features a dedicated race timer that counts down and up, with an internal beeper.
