It is a very precise beam. It seems, however, to be about 3moa at 100yds. It carries the same sharpness throughout the distance that you use it, excepting some ghost images below 100. I see some extra dots sometimes around 30-40 yds. Problem is, I think, that the beam is hitting something with facets that reflect it differently. It might also be something in the air. Every time I've been out to check it lately, it's been a tad misty. It's not hard to tell which dot is the wrong one, as it is larger and diffused. I know which is right for sure because I'm looking at it through the Photon and the crosshairs are right where I want it to be. I told you I was putting shots in the 10 ring at 100 yds. I am not sure that I wasn't influenced by the Photon cross hairs. I do seriously believe it could be done via the laser alone as all you have to do is shoot to the center of the laser dot.
I wouldn't be afraid to use it out to 200 yds, and I'm the kinda guy that absolutely won't take a shot on game unless I'm sure of a killing hit. As much as I hate coyotes, I want to kill them, not just hurt them.
