RE: Range finders ??
I have the Bushnell Scout 1000. I like it a lot. I don't think I would be too worried about how well it does on animals. I have ranged deer out to about 300 and cows to close to 600, but I have never ranged an animal that I have shot. Most of the time you are ranging objects for reference for when the animal you are pursuing walks in, not the actual animal.
