The Swarovski 15x56 is the most favored 15x binocular by serious hunters, hands down. It is quite literally the 15x glass that serious hunters think of when this magnification range and even long range, tripod-mounted optics come up in conversation.
WIth a recent update, the 15x56 SLC is incredibly compact and offers more performance than ever. If you see a marked improvement in your Western hunting success, this is an incredibly powerful starting point.
