● Wireless: no wires to install down the mast adding noise and weight.
● Solar-powered renewable energy; can run day & night indefinitely.
● The first wind cups designed for sailboats; the innovative blade shape maintains equal accuracy when sailing heeled over (unlike standard cup, ultrasonic and propeller anemometers).
● The most advanced features at the lowest price, on sale for US $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.
● 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.
● The first-ever masthead anemometer with crowd-sourcing of live wind maps.
● Amazing mounting options to raise the anemometer after your boat is in the water, without having to lower or climb the mast.
