Every time I use my range finder, I'll range a tree at the same height I am then I'll move down to the base of the tree and range is again to find the difference, it's never more than a half a yard to one yard depending on how far it is. I generally don't get to high in the tree though...16-18ft so I really don't see the need for it for my type of hunting.

I agree those numbers are way out of wack.
