CV7-STBG – Ultrasonic wind vane-anemometer with universal interface

The CV7 ultrasonic wind sensor with the STBG interface is perfect for sailboats equipped with a main navigation system that is not NMEA compatible. The STBG interface converts digital signals into universal signals adapted to all equipment, old or recent.  

SKU: CV7-STBG_M Categories: ,


The CV7 ultrasonic wind vane-anemometer is adapted to sailing constraints.
STBG is an interface that converts NMEA0183 data relative to wind angle and wind speed. This universal interface transmits the data to your new or old equipment in analog format. With the CV7-STBG, you will be able to access all the functions of your navigation instruments.
