A portable, pocket-friendly design

Along with providing a crisp, close-up view of your surroundings, Celestron's Cavalry 8 x 42 monocular will keep you on track. A built-in magnetic compass with an in-eyepiece display shows your subject's direction relative to your position. Plus, an integrated range-finding reticle lets you estimate the distance and size of objects within your field of view. The monocular's compact design makes it easy to take along wherever you go.

The Cavalry's high-grade BaK-4 prisms and fully multi-coated optics offer superb light transmission for outstanding low-light performance. Its long eye relief and folding rubber eyecups provide added viewing comfort, whether or not you wear eyeglasses. The monocular's wide field of view makes it easier to acquire your subjects quickly, and follow them when they move. A waterproof and fogproof design, along with a rubber-armored, non-slip housing make them ideal for boating, hunting, and other outdoor activities. Plus, Celestron includes a neck strap and carrying case for greater portability and protection.
