I am reaching the 800yrd mark but I am horrible at doping wind so thinking about a windmeter. Seems most favor the Kestrel 3500
but was wondering how much more it actually does compared to the 2500? First thing that comes to mind is "wet bulb temp". I don't even know what that is. I am using Shooter on my Iphone if that matters. This is the first and only one that I have used.
