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.
New 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 first masthead anemometer that works with rotating masts.
Simple set-up: calibration to the bow of your boat is not required.
Provides a visual indicator of wind direction and wind angle, unlike ultrasonic sensors that have no wind direction arrow.
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.
Better lightning protection if you don't have wires coming down from the top of the mast.
Masthead mount or portable with an L-bracket for walls/posts and 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).
SailTimer made the first masthead anemometer that transmitted to tablets/smartphones, and this is the 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.
