I have never used the Minox or any "big eyes" for that matter, but I live in Missouri and hunt deer here and can tell you I know of no reason whatsoever to use 15x58 sized binoculars doing that. For what it's worth, just yesterday I ordered a pair of the Minox HGs in 10x52, which I think will work just fine for my hunting over large CRP fields from an elevated box blind. Can't see the need for anything more powerful than that here. Just my two cents...
