Solar-powered and connected by Raymarine's Micronet Wireless technology, the Vertical Wind Station Transmitter Sensor accurately measures apparent wind speed and direction. Designed for high-performance racing boats, the extended vertical height of the wind station transmitter keeps wind direction and speed sensors away from the upward flow of the boat's main sail, improving accuracy and responsiveness. The vertical wind station transmitter can be interfaced wirelessly with other Micronet-compatible instruments and sensors or to a wired SeaTalkng network via an optional Wireless Micro-Talk gateway. Carbon fiber, extended height mast for increased accuracy and responsiveness Compatible with Raymarine Wireless instrument displays Built-in solar panels keep internal battery charged and ready Micronet Wireless network connection for easy wireless installation Fully waterproof, maintenance-free design Compatible with traditional wired SeaTalkng instruments via optional Micro-Talk Gateway (E70361)
