The easy-to-read GNX 21 marine instrument has an inverted LCD screen with white or colored numerals on a black background that clearly displays depth, speed, wind and more than 50 sailing and boating parameters. The bonded glass screen with anti-reflective coating provides excellent readability, both day and night, thanks to high-contrast numerals with a maximum height of 36 mm.

The GNX 21 is the first bonded glass screen with a combination of directly controlled LCD segments and a dot-matrix section for displaying graphic information. The low power consumption - (25 mA) and 350 mW (without backlight) / 400 mW (medium backlight) - is perfect for use on sailboats and makes the screen a valuable tool for boating and fishing. Fully adjustable user profiles provide information on wind, depth and speed. In addition, the GNX 21 includes an auto-scroll feature that automatically switches between data screens for hands-free use. Flat mounting is possible with the included bracket, or you can use an optional flush mount bracket for the ultimate "glass helmet" look for your boat.
