Would anyone here go on a big game hunt, hike far into the wilderness, hunt hard for days, finally line up the scope on an elk, moose, bear, or whatever, only to find the scope fogged up, or miss because the scope got bumped and changed zero? Then say to themselves, "I sure am glad I didn't spend $300-$400 on the scope for my hunting rig." You don't go out of state on expensive big game hunts? How about wounding an animal on your buddies farm? Scopes have come a long way in a very short time, but in my opinion there are some brands to stay away from, they are all inexpensive.
