Bushnell has been the industry leader in high-performance sports optics for more than 50 years. The company's guiding principle is to provide the highest quality, most reliable, and most affordable sports optics products on the market. Bushnell product lines enhance the enjoyment of every outdoor pursuit, including nature study, hunting, fishing, birding, and stargazing. Indoors, the company's binoculars bring the audience closer to the action in fast-moving sports or the fine arts at theaters and concerts. Built to withstand the conditions of the nautical world, Bushnell's Marine series of binoculars provide all the features a captain needs. Independent focus eyepieces, a hermetically sealed nitrogen-purged body for waterproof reliability, easy-to-grip shock resistant rubber armoring, and an optional compass make these a real workhorse. The BaK-4 porro prisms, multi-coated optics, and large UV-coated objective lens all work together to provide impressive light transmission and bright images from dusk to dawn. Both models come in the marine-standard and Coast Guard recommended 7x50 size. The optional compass model easily helps you find your heading with the built in compass. The compass is internally stabilized and provides a readout on an illuminated LCD in the left eyepiece. The compass does not obstruct your field of view.
