I guess a typical optical scope is useless for archery, even though I've seen some people use it. I have no idea if it's not there just for show, maybe not, though I highly doubt how effective that could be. Anyways, I can imagine how one type of scope can be effective for bow hunting. I'm talking of spotting scopes, of course. And I think of purchasing one. But I'm not sure which one I should get. The Minox MD is one of the best of them, and the cheapest one, but I'm not sure just how good it is. Others are more expensive, and I'm not sure just how much they can offer. Any advice?
