I bought this a couple months ago. I have only played with it around my house, but I have ranged deer a little over 900 hundred yards on normal mode. Trees over 1500 so far. If I put it on ELR mode I can range rocky cliffs ( free hand) on the mountain side, the furthest so far is 3782 yards. I have the ranger 1500 and the Razor has better glass and brighter and the readings are a lot faster. Best part is it has a life time warranty.
