Marine Instrument with Standard 4? LCD

  • Large, easy-to-read black digits and graphs on a white or colour background provides high contrast and high visibility; choose from 7 customisable backlight colours
  • Glass-bonded display with anti-glare lens avoids fogging
  • Fully customisable user profiles for sail or power boating to display most important marine and vessel data
  • Low power consumption (25 mA) with 350 mW (no backlight)/400 mW (mid-level backlight)
  • 5 display configurations plus gauge and graph mode to display depth, speed, wind and 50+ marine and boat parameters

The easy-to-read GNX 20 marine instrument display with black digits on a white or colour background 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 20 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 20 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.
