Review: Best of low tech - This anemometer is so easy to use. Did have to read instructions to set units, but no problems. Reliable and tough with accurate wind readings. The temps seem to be a little slow when removing from the vehicle and reactive to wind readings, hence the 4 stars.
Review: Good for a Quick Check - Works very well as a relative air flow measurement tool. Though the instrument has a nice internal absolute air flow computation, in practice the accuracy isn't very good. Use it as a comparison tool and you'll be very happy.
