Binoculars are for glassing & spotting.
Spotting scope is for judging, evaluating, observing, and can be used for spotting.
Using your high power rifle scope as a way to avoid either of the above can get you shot at. Or maybe killed.
Yep, I have shot at sheep hunters, (no not to hit them). If someone is in a seated position, wrapped up in the sling, elbows on his knees, looking through his variable hi-powered rifle scope, mounted on a magnum rifle, and it is pointed right at me.
Remember that firearms safety rule, yea the one about don't point the firearm at something, unless you plan to shoot. Well the guy your aiming at knows the same rule.
Your rifle scope is NOT a substitute of BINOCULARS. The life you save may be yourown........
