Thread: Which is the best wind meter for wind estimation

Wind meters are great to give you an indication of wind speed at your location. You can use this information to make a slightly better informed decision about the effect of the wind along the bullets entire trajectory.

I have a kestrel 2500... it works well. I didn't bother getting one with all the bangs a whistles and truth be told i tend to use vegetation more than the kestral when judging wind effect. Norway put together a cool video demonstrating using vegetation to judge wind.

Gillie I will bow to you considerably greater knowledge on this matter. My understanding to now has been that wind has the greatest affect on a projectile's flight at the target end where the projectile is travelling slowest and dropping quickest. What I was alluding to above was that a hand held device cannot measure wind at target (unless you happen to be at the target) and that wind variables (speed, direction) could be completely different from those at the shooting position down at the target position. Bill999, however Gillie responds to this (or not) be guided by his advice over my comments.

Although per inch moved yes the wind will deflect the bullet more at the end there are so few inches left to move it doesnt matter as much as the wind when it leaves the rifle. A small deflection when the bullet has 1000m to go makes a bigger difference...

I bought an $18 one from dx,com, its good enough IMHO to get me onto the target....ie tells me the wind is varying 8~12kmh (say) so pick a mean of 10, I know the range so I have a band of MOA to choose from I look downrange and try to judge if it looks stronger or weaker or a different angle and pick a sighting shot MOA from that and off I go....For $18 its helped a lot IMHO...I really wonder that a $100 unit would have helped any more...

The other thing I do is a wander about looking around me and take a reading to try and get my eyes to better judge wind....not getting to far at the moment though.

Jkey should be nervious, I often check out the flag on top of the beehive.....I mean tell an assasin what the wind is doing outside his window why dont you....doh.

It does have the biggest effect, but the least distance to drift away. So say 1moa deflection at 900m, to a 1000m target, so 100m to travel = 1inch off. Say 1/2 the deflaction on leaving the gun, say 0.5moa deflection at 100m to a 1000m target is is 900m to travel how many inches off?
