Just a quick update, the Nikon will range an antelope at 950 yards. It doesn't have the best glass, but for hunting, it works just fine for my needs. I've used it enough that I actually had to replace the battery during 2nd rifle last week. Looks like the battery lasted 10 months with pretty extensive use. I actually use it at work every now and then, and ranged stuff very often during all three hunting trips this season.
The furthest I've gotten mine to read was something like 3,200 yards. It just flashed that distance long enough to get a read, and it was on the side of a building. Thanks for the help everyone. I'm happy with the Nikon unit and would recommend it to others.
