Take your deep sea explorations to the next level using the waterproof Bushnell 7x50 Marine Binoculars with Compass. These binoculars possess all the right characteristics that you find in nautical binoculars beyond their class: a Porro prism design for enhanced perception of depth, individual focusing, an O-ring-sealed nitrogen fill for fogproofing, and a thick rubber armoring designed to resist impact and corrosion from saltwater. In addition to the clarity and brightness of full multi-coatings, the optical system also offers wide 50mm objectives lenses and some protection from harmful UV rays. To set itself apart as a truly marine binocular, it allows you to make accurate nautical measurements and notes with its built-in analog compass and an illuminated range-finding reticle.
