Not Really
All a windmeter tells you is what is going on where it is sitting. That is not of much use down range.
But, these little devices are a neat way to see just how bad things are. At several Matches last year, John Horn had a little hand held thing that told the velocity ebb and flow. At Seymour, I remember it would gust from 10 to 25 mph in a matter of seconds. That explains some of the groups that were shot........jackie
