Sirs I have just started taking real long shots seriously [>600yds]and my mentor suggest a windmeter. It must at least display the following information: Wind speed Altitude Barometric pressure Temperature To benchmark, I think a Kestrel 2500 matches the requirement but am happy to consider other units. What have you got kicking about in a draw or cupboard or at the back of the gunsafe you don't use or need anymore? Thanks for reading. HP P.S. I am happy to pay postage/shipping to the UK.
