Has any one used one of these or got any Veiws on them. A friend of mine in the forces was quite impressed with the standard windwatch (bright yellow in colour) a few years ago, but I was never overly sure about them.
I have one of these, I use it to measure windspeed at potential windfarm sites when doing bird surveys etc. Everything seems to be very accurate, the impellers are inside a ball that can be swivelled shut to protect them. Altitude and barometer work well when compared to os maps and local weather stations. I'm considering upgrading to the new 'weatherman'
