The easy to read GNX 21 marine instrument has an inverted display with white or color digits on a black background that clearly shows depth, speed, wind and 50-plus marine and boat parameters. Its glass bonded display with anti-glare lens coating provides excellent daytime and nighttime readability with high contrast digits scalable up to 36 mm. The GNX 21 is the first glass bonded marine instrument with a combination of directly driven LCD segments and a dot matrix field to display graphical information. Its low power consumption – (25 mA) with 350 mW (no backlight)/400 mW (mid-level backlight) – is perfect for use on sailboats, and provides a valuable instrument for cruising and fishing. Fully customizable user profiles display wind, depth and speed data. Plus, the GNX 21 includes an auto-scroll feature that rotates through data screens for hands-free operation. It can be installed with the included low profile flush-mount or an optional flat mount for the ultimate glass helm solution and custom look for your boat.
