Nasa Wireless True Wind System c/w Data Box and Tactical DisplayThe Clipper wireless wind is supplied with a wireless masthead transmitter, a base unit and a Clipper True Wind display unit. The wireless masthead transmitter is powered by an internal battery which is charged from ambient light using a small solar panel. A few dull days will not affect performance. When fully charged, it is capable of two thousand hours of full operation in total darkness. The masthead transmitter sends data wirelessly to the base unit, which is powered by the vessel’s 12 Volt supply, the base unit receives wind speed and direction data from the masthead transmitter and sends it to the display.
The Clipper True Wind display is in the industry standard 110mm square case. Exceptionally large and clear display with 60 segments for full 360 degree direction indication. The display shows apparent wind speed and direction and, when connected to a log or GPS, it can also show true wind speed and direction.
