About this product

Model:  cel_cvlry_mon_8x42_71215
Part Number:  71215

The rugged Cavalry Series monocular is 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 monocular easy to grip while protecting it from hard use. The olive drab color offers concealment in the field. 

As an optical instrument, Cavalry offers professional features including a high-grade BaK-4 prism and fully multi-coated optics for superb light transmission. Several models in the Cavalry Series, including the 8x42 monocular, have an integrated 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.
