Ready for the rigors of the sea, the Marine Series 7×50 Binoculars from Bushnell offer a corrosion resistant and 100 percent waterproof performance with optics optimized for the open water. Thanks to hermetic sealing, the Marine Binoculars will remain water and fog free even if completely submerged. The durable, non-slip, non-skid rubber armor helps to ensure the binoculars stay comfortably in your hands, but also adds buoyancy should you or the binoculars go overboard. The Coast Guard recommended 7x magnification, 50-millimeter objective lens configuration with the Porro prism system delivers a wide field of view, ideal for the open water. Meanwhile, the premium BaK-4 prism glass and fully multi-coated optics with UV protection offer the clarity and light transmission you are looking for. Includes lens cleaning kit
