A wind, speed and depth system with NMEA 2000 connection. The wind signals from the Nexus twin vane masthead transducer are converted into NMEA2000 data via the GND10 box. Speed, depth and temperature data from the DST800 transducer is fed into both the GMI20  multifunction instrument via the NMEA2000 backbone.

The wind transducer features renowned Nexus twin-fin technology with 3-bladed propeller providing more accurate TWS in lighter air and more stable TWA. Optic reading provides superior accuracy and excellent linearity.

The GMI 20 digital marine instrument display is perfectly designed for both power and sail vessels. Designed to clearly show depth, speed, wind and 100+ marine and vessel parameters, its large, bright 4" colour display with extra large digits is easy to read at a distance and has a 170 degree viewing angle. A glass-bonded lens prevents fogging and increases contrast. Daylight readability is enhanced with a high contrast colour scheme. For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode colour scheme along with a dimmer control. Screens can be set to auto-scroll, cycling between pages automatically without your having to do a thing. This is especially advantageous to sailors as it allows you to install the unit(s) in a greater variety of locations on the vessel. Default profiles can be customised for powerboat, sailboat, fishing, engine/fuel, plus several other user-specified profiles. Power is supplied by the NMEA 2000® network. In addition, the GMI 20 also features a dedicated race timer that counts down and counts up, with an internal beeper. Included are 2 trim snap piece cover options which allow you to match the GMI 20 with the new GPSMAP® 500/700 series, GPSMAP 8000 Glass Helm series or legacy Garmin chartplotters.

The Airmar plastic smart thru-hull mount transducer provides depth, speed and temperature data to the NMEA 2000 network. This 100 W transducer has a depth of 100 ft and operates at a frequency of 235 kHz. This frequency has been selected to eliminate interference with other echo sounders that may be fitted to the boat. The embedded digital signal processor ensures accurate speed from the paddle wheel even a speeds below 5 knots. The transducers skin fitting has a self-closing valve that minimises water flow into the boat when the transducer is removed.
