Modern components for a reliable display
Garmin GMI20 & GNX20
Garmin GMI20 GARMIN's brand new GMI20 multifunction instrument displays data such as log, water depth, temperature, wind, GPS data, tank contents and much more, both manually and automatically. It features a 4" colour display that is easy to read even from a distance and in bright sunlight. The device is compatible with the NMEA2000 data format and can therefore be integrated into most existing on-board networks.
Garmin GNX20 The GNX 20 marine instrument features an easy-to-read display with black digits on a white or coloured background. It allows you to easily read depth, speed, wind and 50-plus marine and boat parameters


Airmar DST810
The DST810 plastic thru-hull transducer reliably and precisely measures depth, speed and temperature readings in the water. Thanks to NMEA2000 and Bluetooth connectivity, data can be displayed in a variety of ways. The sensor can also be calibrated quickly and easily via the Bluetooth interface using the Airmar Cast App. The device can measure depths up to 100 m, speeds up to 45 knots and temperatures up to +40 °C. A 5 Hz signal output ensures smooth playback on your display device.
Wireless connection via Bluetooth also allows easy calibration of sensor data via the Airmar Cast app.
gWind Windsensor (wired)
The gWind-transducer uses Twin-Fin technology with a three-bladed propeller to provide more accurate data for true wind speed at very low wind levels. The twin-fin design provides more precise data about true wind speeds, and the three-bladed propeller ensures greater, constant efficiency.
