The eye is most sensitive to green; the beam is visible in air showing dust in path, so the beam is easy to see and direct to target. I use it on Marlin 1894 held loosely near shoulder or hip high to hunt feral hogs in brush. Easy point. Sure kill.
Pros: Brightness, Quality CR123 Battery
Cons: Must unscrew front protective cap to adjust w/wrench
