BUILT TO WITHSTAND EXTREME NAUTICAL ENVIRONMENTS - AND FLOAT IN THEM. We suggest you keep them on board, but made our Marine series binoculars bouyant, waterproof and corrosion resistant, so a little dunking won't deep-six your day. You'll appreciate the ultra-bright, crisp views granted by their multi-coated optics and premium BaK-4 prism glass. Rugged rubber armouring provides a sure grip, absorbs shock and keeps them from sliding in rough conditions. They're essential equipment if you spend much time on deck and aren't fazed by a little time off it.

A floating neck strap is included - just in case!!
