Bushnell Marine 7x50 with Compass. A premier choice for spotting marinas, deadheads or the fisherman's best friend, feeding birds. Built to withstand rugged nautical conditions, they are nitrogen-purged to provide reliable 100% waterproof/fogproof performance. Hermetically sealed to prevent moisture from creeping in. Impressive light transmission from BaK-4 porro prisms, multi-coated optics and large UV-coated objective lenses brighten images at dusk and dawn. They float and the easy-grip rubber armoring protects the binocular and provides a secure hold if things get rough.
