The Navigator 7x30 Binocular from Steiner was designed and engineered for the hydrosphere, whether the offing or the deep-sea of the salty brine, or a fresh water lake or river or estuary, a shoal or a sound. This binocular has fins and scales; metaphorically speaking of course.Sturdy waterproof construction down to 2m is achieved via special sealing technologies that also keep out the dust, dirt and humidity. A fog-free viewing and moisture protected performance is furnished by the two-valve system of dry nitrogen pressure filling. Makrolon fiber reinforced polycarbonate bodies with rubber armoring make the Navigator rugged, shock resistant and slip-proof. The weight is evenly balanced and the 7-times magnification effectively stabilizes the binocular, providing a firm hold and a stable image. Individual eye Sports-Auto-Focus with diopter adjustment and soft silicone cylindrical eyecups allows comfort and customized viewing. This binocular lives up to the Steiner legacy.
