Using a Garmin gWind Transducer Installed on a Rotating Mast

Can Garmin gWind transducers be used on a rotating mast and are most often found on catamarans, trimarans, and racing sailboats? Garmin does not offer a gWind wired or gWind wireless transducer capable of calculating the rotational movement of a mast. Garmin gWind transducers are secured and fixed in place, referencing the vessel's bow to calculate True and Apparent wind data. Mounting a Garmin gWind transducer on a rotating mast will cause inaccurate wind data.  

Compatible Garmin chartplotters can utilize third-party wind transducers to calculate the mast's rotational movement. The third-party wind transducer must use the NMEA 2000 network and operate PGN 130306.

Compatible chartplotters include:

• GPSMAP 74xx / 76xx

• GPSMAP 84xx / 86xx

• GPSMAP 7x2 / 9x2 / 12x2

• GPSMAP 7x3 / 9x3 / 12x3

• GPSMAP 10x2 / 12x2 (push button)

• ECHOMAP Ultra 10x / 12x

• ECHOMAP UHD 6 x / 7x / 9x

• ECHOMAP PLUS 7x / 9x
