A friend of mine that is a rabid bowhunter (with no apparent limit to his bowhunting budget) likes the Leupold. He says that he can see into the dark areas and shadows better with it. He did spend some time with the other popular models but to his eyes the Leupold was the winner. I am more of a rifle hunter and normally use a Leica, but I do have a couple of SIG rangefinders that I like..
