[QUOTE="jmden, post: 600098, member: 1742"] Beam divergence is a key factor in rangefinder performance. Your Swarovski has a round shape beam with a larger beam divergence (wider angle so it gets bigger [the beam width, that is] the further away from you it gets. A wide, round beam and cause problems quickly, especially on flat ground as the bottom of the beam could be ranging at 500 yds and the top at, say 800 yds with your target likely somewhere in the middle and good hits on the target tough to get. I think many folks like a small beam (narrow angle so the beam doesn't get so big way out there so you can be more confident the beam is on your target and not a bunch of other stuff) that is retangular with the horizontal dimension longer than the vertical dimension--more in line with the shape of the body of an big game animal minus the legs and head. But small beam divergence (narrower beam than wider) is, I think, a good thing in most instances.
