    The GNX 20 marine instrument is an easy-to-read device with a 4” LCD display and black digits on a white or colour background that clearly shows depth, speed, wind and 50-plus marine and boat parameters. The display is also viewable in both day and night environments thanks to its glass-bonded display with anti-glare lens coating and high-contrast digits scalable up to 36 mm. Perfect for use on sailboats, the GNX 20 provides fully customisable user profiles, auto-scroll, easy installation and also proves to be a valuable instrument for cruising and fishing.
