Take your deep seas' explorations to the next level using the waterproof Bushnell 7x50 Marine Binocular with Compass. This binocular possesses all the right characteristics that you find in a nautical binocular beyond its class: a Porro prism design for an 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.
