It doesn't really have a good manual so I looked at it first and thought it was a POS, everything was fuzzy and fuzzy. I went through the documentation and decided to just play around with it and see what happens, eventually I found the focus setting and really started to see what I was pointing at. Seems pretty accurate, I checked side by side with my buddy's vortex range finder, Bushnell danced a bit, I ran 150 yards 4 times and got 2 150 yards, 149 yards and 151 yards. It was lighter and faster than the vortex, not as transparent as glass, but it will definitely work for what I want to do with it. I would recommend.
