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” color display with extra large digits is easy to read at a distance and 170 degree viewing angle. The easy-to-read Garmin GNX 20 marine instrument display with black digits on a white or color background clearly shows depth, speed, wind and 50-plus marine and boat parameters.

The Garmin GNX 120 provides a flush mount glass mast look, and its glass-bonded high-contrast monochrome LCD display avoids fogging. Low power consumption of 0.36 W daylight with no backlight and 0.4 W nighttime with mid-level backlight preserves your batteries
