The rugged Cavalry Series is an outdoor binocular designed for hunters, boaters, law enforcement, and military personnel. Engineered to withstand the elements, Cavalry is fully waterproof and nitrogen purged to prevent internal fogging. The housing is protected by durable rubber armor, making the binoculars easy to grip while protecting them from hard use. The olive drab color offers concealment in the field. As an optical instrument, Cavalry offers professional features including high-grade BaK-4 prisms and fully multi-coated optics for superb light transmission. The Cavalry 7x50 binocular features an integrated GPS, digital compass, and reticle. The compass will help you determine the direction of objects in relation to you and the reticle allows you to determine their size and distance away. The Cavalry Series is a useful tool for anyone out in the field or on the water.
