Garmin GNX 21 Multi Function Display

The easy-to-read GNX 21 marine instrument has an inverted display with white or colour 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 customisable 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.
