The traits that earn Steiner binoculars such respect in combat - incredible toughness, exceptional clarity and reliable optical performance - are found in the civilian Steiner Military-Marine series. And, they feature Steiner's Sports-Auto-Focus system for crisp, sharp images near and far without constant adjustment. Just set the focus to your eyes once, and you'll have a constant, clear view of objects from 20 yd to infinity. Higher magnification and larger objectives are ideal for open terrain and hilly country, and for spotting game in low-light conditions.
