- Description
The easy-to-read GNX 21 marine instrument features an inverted display with white or color digits on a black background, clearly showing depth, speed, wind, and more than 50 other marine and boat parameters. Its glass-bonded display with anti-glare lens coating provides excellent readability day and night, with high-contrast digits scalable up to 36 mm.
The GNX 21 is the first glass-bonded marine instrument to combine directly driven LCD segments with a dot-matrix field to display graphical information. Its low power consumption — just 25 mA, using 350 mW (no backlight) or 400 mW (mid-level backlight) — makes it ideal for sailboats. Customizable user profiles allow you to display wind, depth, and speed data the way you want, while the auto-scroll feature rotates through data screens for hands-free operation.
Installation options include the included low-profile flush mount or an optional flat mount, providing a glass helm solution and custom look for your boat.
Note: Color backlight is not visible in daylight.
