The background colors can be customized as you prefer so that the contrast and visibility are optimally adapted to the lighting conditions. It also connects through the NMEA 2000 network to show 2 data fields and a digital wind rose simultaneously to show real and apparent data about the wind, the steering pilot, the speed of the boat and much more. The automatic screen change function allows you to change the data screens without user intervention. Low energy consumption, 350 mW during the day (without backlight) and 400 mW at night (with an average level of backlight), ideal for sailing boats. Customizable configurations include more than 15 important nautical parameters about wind, speed and navigation. It is installed in a simple way, well flush, well recessed. It can even be connected wirelessly with a plotter or a nautical smartwatch with GPS quatix® 3 with GPS to transmit wind data directly to your wrist.
