I sell em at work, and the only ones we sell are to guys who basically won't buy anything but Vortex, there are a lot better options, as far as I'm concerned. Sig Sauer Kilo 2000 or 2200 are great options, in the same price range, and will range deer at 1000+ yards. Sig also has a lifetime warranty. They're also coming out with a range finding Bino (Kilo 3000, 10x42) soon. The Vortex has a black reticle, which I found tough to read, vs a red readout on the Sig. Not trying to make this sound like a sig ad, but they do seem to outclass the vortex in most ways. The problem with most rangefinders is that they won't range animals at anywhere near the max distances they advertise. In that respect, neither will the sig, or any other that I know of. But the top end ones will range deer at 1000 yards, or close to it. That may not be a real consideration for most...I know I'm not shooting at anything 1000 yards away....but it is a consideration when you look at performance vs price, in my opinion.
