Solar-powered renewable energy; can run day & night indefinitely.
Innovative wind cup blades maintain equal accuracy when sailing heeled over.
The best features, and also the lowest price on the market, on sale for US $350. (Customers outside North America: the hardware is just $150 with any customs duty, tax and fees only on that. Another way we are lowering your costs. Your cloud server activation is $200, for a total of $350.)
The first masthead anemometer with a digital compass right in the wind direction arrow.
That means you even get wind direction while docked or swinging at anchor, when GPS heading is not available.
With new features in app updates on iOS & Android, the Wind Instrument actually becomes more useful over time.
2016 version shown above adds an off-switch for storage, new antenna arrangement for tall masts, and incredibly thin tail electronics with solar panels 40% thinner and rest of trailing edge just 3.5 mm (0.13"). Full details.
The only masthead anemometer that works with rotating masts.
No base unit required.
For sailboats of all sizes, from keelboats to centerboard racing dinghies and even small multihulls (no 12-volt battery required).
Small vertical design rather than the common horizontal structure, to deter large seabirds.
Masthead mount or portable with small adapter for 1/4" tripod / Gorillapod / GoPro mount.
Battery uses advanced design for unusually wide temperature range from tropical heat down to -40 degrees (C/F).
We made the first-ever masthead anemometer that transmits to mobile devices, and this is our newest version.
Designed to work with third-party apps and hardware using the industry-standard NMEA 0183 format.
Accessory for plugging in to on-board wired marine electronics.
Wind direction equally sensitive all the way around; no dead band at the end of the rotation as in wind direction sensors with potentiometers.
Transmits every second: twice as fast as our previous version.
