[QUOTE="LouBoyd, post: 592225, member: 9253"] The question is how well wind measured at the shooting location correlates to the wind over the trajectory which causes bullet deflection. That correlation depends mostly on how the wind flows over and around the terrain. On flat terrain with no storms and stable conditions the correlation can be fairly good, but a shooter still needs to be able to determine downrange wind conditions by other methods to determine if the correlation is good or not. I'm not advising against buying the meter and calculator. Just don't expect the meter to make your first shot at 1000+ yards have an under 4" error from point of aim in conditions where the uncorrected wind deflection may be several feet. If it doesn't it's not because the wind meter isn't accurately measuring the local wind. All of the long range shooting you do is useful in learning how to make corrections from what you can observe downrange. More important is learning when adequate corrections can't be made from the information that's available. [/QUOTE]
