Take your boating expeditions to the next level using the waterproof Konus 7x50 Abyss Marine Binoculars. These binoculars possess all the right characteristics that you want in nautical binoculars: a Porro prism design for enhanced depth perception, center focusing with a large slip-resistant knob, a nitrogen-filled housing to keep it from fogging, and a rubber armor designed to resist impacts and give you a sure grip in wet conditions. In addition to glare-reducing lens coatings, the optical system also offers a generous exit pupil that helps to offset the disorientation of a moving horizon when looking through them on rough and rolling water.
