Hi Skyewright,
I’m interested that you seem to be seeing higher start up speeds on your Vortex than I do.
Mine turns in a barely perceptable breeze and I see readings down to 1.2 KM/h which is 0.75 MPH.
I’m using the new HB wind board.
Very very happy with results and Vortex and E-Vane. The combination of these instruments and the HB 1-wire board works brilliantly.
