Here's another one, if your not into downloading the necessary ap and interfacing with a smart phone and also save a few bucks. Plus it plays cool music...or maybe that's just the video.
If I'm shooting from the bench for my best group or score card, I have never used a wind meter. I use several flags and a windprobe. A wind meter in the field is great if you want to know the wind speed. Other than that, you need to be able to read your surrounding conditions. With windflags and a windprobe you will gather much more information before taking your shot.
