It's not that I have eagle eyes. Just the opposite actually. As some of you know I still hunt the timber. Some hunters will use low power binos for still hunting, but over the years ive gotten pretty good at spotting parts of game showing behind tress, rocks etc. with my eyes only.
So, i'm always in iron sight range. If I can't spot the game with my eyes. I sure can't hit it with iron sights.
Sorry, to be off topic. I just thought i'd mention the other side of glassing.
