I have a Bushnell Conx, as well as the older ARC 1600. Also a Leica 1600. The Leica has great glass, to the point that I occasionally leave my binos at home when hunting. Both bushnell's range better than my Leica though, and I have never had the issues that some in this thread have had. No doubt some of that is luck, as lower priced items tend to be hit or miss.
However, I wonder if those of you who can't hit the broad side of a barn with your Bushnell LRF's, have checked them for beam accuracy/divergence. If your beam is hitting off to one side or another, you can't expect to get hits on realistic targets at longer ranges. If your LRF has this problem, Bushnell will swap it for a new one very quickly.
For the money, I think the CONX is incredibly tough to beat. A far as the new Terrapin goes, I am curious to see it, but a friend of mine has already tested it, and found it severely lacking compared to the older models. He has a bunch of high end models to use at work, but chooses a CONX for personal use.
