Ill add my .02 and that is listen to what shooters is saying. However most of us will not be able to afford a 10k$ vectronix. Any rangefinder manufacture besides vectronix WILL NOT range on soft targets, such as game, what is stated on the box. At best you will get 3/4 of the stated ranging capabilities. I myself shoot and deer hunt in the same location so I pre-range everything and have most memorized past 700 yards.

Just a side note, make sure your caliber has enough energy to kill before you go shooting at animals. Paper and steel is a different story

Only accurate rifles are interesting.
