No need to buy the whole thing

The Davis 6410 Anemometer is a replacement anemometer with mounting base for wireless and cabled Vantage Pro2 and Vantage Pro weather stations. Includes both wind speed and wind direction sensors, mounting hardware, and 40 ft. (12 m) cable. Rugged components stand up to hurricane ‐ force winds, yet are sensitive to a light breeze. Includes sealed bearings for long life. The range and accuracy specifications have been verified in wind ‐ tunnel tests. In areas where icing of the anemometer is a problem, drip rings deflect water from the joint between moving parts.

The anemometer measures and displays wind speed and direction. The data is used to calculate other wind-related information such as wind run, wind chill, and the temperature-humidity-sun-wind index. This anemometer can be used with EnviroMonitor or any Vantage Pro2-compatible system.
