How far?
How bright?
What size of object do you want to range?
Inside 500yds on a mound of dirt on a moderately bright day, pretty much everything works.
Extend the range, increase the brightness, reduce the size of the target, many rangefinders DON'T work.
I have used Leicas, Bushnell Elites, Swarovski. I have tried other peoples lower end Bushnells, Nikons and the recent small Leupold.
I shoot very far and in the summer. I range on light coloured hillsides and everything has trouble ranging beyond 800yds besides the Swarovski. The S can range to a mile easily. Furthest range was 2000yds.
So it really depends on what you want to do.
Any wind meter will work just fine. Until you start shooting beyond a mile, the changes in ambient conditions have little affect on modern powders and the ammo they can produce.
Most wind meters from the Caldwell through to the most expensive Kestrel will give you a good wind reading but only where you are. You still need to study the wind between you and the target.
