The Garmin gWind transducer features twin-fin technology with a 3-bladed propeller for accurate TWS in lighter air while the twin-fin design gives a stable TWA. The 3-bladed propeller, unlike a cups design, is always efficient. Combined with optic reading this transducer provides superior accuracy at low wind speeds and also provides for excellent linearity.The includedGND 10black box bridge enables theNexus Networkand compatible Garmin chartplotters to share critical NMEA 2000 data. The GND 10 enables Garmin chartplotter owners to use Nexus sail equipment and vice versa.FeaturesThree-bladed propeller for accurate True Wind Speed (TWS) in lighter airTwin-fin design gives a stable True Wind Angle (TWA)Optic reading technique for superior performance at low wind speeds with excellent linearityGND 10 black box bridges NMEA 2000 data to Nexus Network and enables Garmin-compatible chartplotters to integrate with Nexus sail equipment and vice versaEasy plug-and-play installation between Nexus, Garmin chartplotters, NMEA 2000 and USBSpecificationsUnit Dimension, WxH: 17.7″ x 11.8″ (610 x 345 mm)Weight: 260 gCable Length: 25 mWaterproof: Yes (IPX6)Temp Range: From 5F to 158F (-15C to 70C)Storage Temperature: From -4F to 176F (-20C to 80C)Voltage Range: 9-16VPower Usage: 0.33WTypical Current Draw at 12 VDC: 28 mACompass Safe Distance: N/AAccuracy Angle: Better than 1.5Speed: Better than 3%Wind Speed Range: 0. 8-90 knots (0. 4-50 m/s)NMEA 2000 Load Equivalency Number (LEN): N/AWireless Connectivity: NoIn the BoxgWind transducerGND 10NMEA 2000 drop cable (2 m)NMEA 2000 T-connectorMast cable with female connector (25 m)Nexus female field-installable connectorMast bracketMounting hardwareDocumentationDownloadsInstallation Instructions Technical Reference for Garmin NMEA 2000 Products .input-wrapper a { text-decoration: none; / Removes underline / background-color: transparent; / Ensures no background color / } .input-wrapper a:hover { text-decoration: underline; / Adds underline on hover / background-color: transparent !important; / Removes grey highlight / }
