Bushnell Marine 7 x 50 Waterproof/Fogproof Binoculars w/Illuminated Compass 
Built to withstand extreme nautical environments. And float in them. We suggest you keep them on board, but made our Marine series binoculars buoyant, 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 armoring 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.
