Garmin GNX 21 - marine instrument display

The GNX 21 is a Garmin digital marine instrument that shows key voyage parameters on one screen - including depth, speed and wind data, as well as much other information from the boat's onboard systems, over 50 parameters in total. The device works on an NMEA 2000 network, so it reads data from connected sensors and other Garmin devices installed on board.

Readable display

The screen is made of composite glass that reduces glare and stays readable both in full sun and after dark. The digits are displayed in an inverted layout - light on a dark background - and their height can be adjusted to your needs, up to a maximum of 36 mm, which makes reading easier from a greater distance at the helm.

Installation on board

The instrument is designed for permanent mounting in a dashboard or cockpit, next to other yacht instruments. The plastic housing is suited to conditions at sea.
