Thought I would try the Thermal Scopes everyone is raving about. I first tried the Digital Night Vision but wasn't satisfied with it. Had issues with seeing things at a distance due to IR illuminators not providing enough illumination, couldn't get things collimated between the NV Scope and the IR. Finally took the plunge and bought Trijicon Thermals, excellent product. Can see a mouse at 200 yards in a cut soybean field. Can see the whiskers on cattle at over 100 yards. First Thermal Double, the second coyote was at 400 yards running, ok ok yes alot of luck involved in that shot, I admit.
