Two Great Products, One Price
You can get the new Air Link for $99 if you want to get the data OUT of your wired NMEA network to your smartphone apps. Or, you can transmit from the wireless SailTimer Wind Insrument™ to the Air Link to get wireless wind data IN to your chartplotter.
Best features, lowest price: SailTimer developed the first-ever sailboat Wind Instrument that could transmit to smarphones, a decade ago. This is a mature product. It comes with lots of innovative features: lithium battery, the only anemometer that remains equally accurate whether upright or heeling over, carbon-fiber pointer. You can even raise it on a halyard without needing to climb or lower the mast. Transmit to the Air Link for your plotter, or to your phone/tablet to use with lots of apps. This also appears to be the only masthead anemometer with a digital compass right in the wind direction arrow. That means easier installation (no calibration to the centerline of your boat), and it even works on rotating masts. Order direct from the manufacturer for just $399.99.
