Garmin's GNX 20 is the first glass-bonded marine instrument with a combination of directly driven LCD segments and a dot-matrix field that directly displays graphical information. Its low power consumption makes it perfect for use on sailboats, and is also ideal for cruising and fishing.

The Garmin marine instrument displays black digits on a white or colour background that clearly displays depth, speed, wind and over 50 other marine and boat parameters. The glass-bonded display has an anti-glare lens coating and offers excellent daytime and night-time readability, with high-contrast digits scalable up to 36mm. If you'd prefer an inverted display, check out Garmin's GNX 21 Marine Instrument.

Fully customisable user profiles display depth, speed and wind data. Furthermore, an auto-scroll feature rotates through data screens for hands-free operation. The marine instrument can be installed with a low profile flush mount (included) or optional flat mount for the ultimate glass helm solution and custom look for your boat.

Key Features:

5 display configurations plus a gauge and graph mode that display depth, speed, wind and over 50 other marine and boat parameters.
Choose from 7 different backlight colours, or even create a customised colour.
Fully customisable user profiles for sail or power boating to display important marine and vessel data.
Glass-bonded display with anti-glare lens avoids fogging.
Large, easy-to-read white or a choice of seven colour digits on a black background for high visibility in low light or darkness.
Low power consumption: 25mA with mW (no backlight), 400wW (mid-level backlight).
