What I'd like to know from those of you that use a meter for reference is:
What brand and model?
Accuracy (compared to local weather station data)
Type of meter (vane, cup, hotwire)
1) Skywatch(tm) Explorer 2
2) 0 to 150 km/h (93mph)
3) Claimed "precision" plus or minus 3% but I haven't got round to comparing this with another source (annoyingly I was once using it at an airfield but did not have my scanner to listen to the reported winds).
It needs to be pointed directly into wind and does not show well sudden large changes in windspeed ,due to a low update rate (twice a second) and possibly also,the time needed to speed-up or slow-down the impeller.
It is interesting to be able to put numbers to what you are experiencing but,as has already been said here,it can be of little if any practical use in most circumstances.
