Magnifying life does, indeed, include sea life. And these are just the binoculars to do it. Our legendary 7x50mm Marine binoculars are a premier choice for spotting marinas, deadheads, or the fisherman's best friend, feeding birds. Built to withstand the conditions that come along with the nautical world, they are nitrogen-purged to provide reliable waterproof/fogproof performance. Impressive light transmission from BaK-4 porro prisms, multi-coated optics and large UV-coated objective lenses brighten images from dusk-to-dawn. And, all models not only float, but easy-grip rubber armoring protects and provides a secure hold should things get rough. Always nice, should an unexpected swell or throttle burst take you by surprise.
Specifications for this Bushnell binocular include:
- Magnification: 7x
- Objective lens: 50mm
- Field of view at 1,000 yards: 350 feet
Tech Talk
Objective Lens: The diameter of the objective or front lens. The larger the objective lens, the more light that enters the binocular, and the brighter the image.
Field of View (F.O.V.): The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide angle binocular features a wide field of view and is better for following action. Generally, the higher the magnification, the narrower the field of view.
Porro Prism System: In porro prism binoculars the objective or front lens is offset from the eyepiece. Porro prism binoculars provide greater depth perception and generally offer a wider field of view.
Product Description
7x50mm Digital Marine Features a built-in 3-axis digital compass for true heading. Built to withstand extreme nautical enfironments. And float in them. The U.S. Coast Guard suggests you keep them on board, but we made our Marine series binoculars buoyant, waterproof and corrosion resistant, so a little dunking won't deep-six your day. You'll appreciate the ultra-bright, crisp views granted by their multi-coated optics and premium BaK-4 prism glass. Rugged rubber armoring provides a sure grip, absorbs shock and keeps them from sliding in rough conditions. They're essential equipment if you spend much time on deck, and aren't fazed by a little time off it.
