Carson Optical adds a model to its premium XM-HD (High Definition) series -- the 10x50mm XM-HD. With HD light-gathering, performance technology and large 50mm objective, the 10x50mm model lends itself particulary well to dawn/dusk low-light viewing. Building on the XM platform, the 10x50mm XM-HD incorporates features and elements key to lightweight, well-balanced, full-sized binocular design. Fully multi-coated lenses and phase-coated optics ensure crystal clear images with less glare and full range of color. Rubberized armoring offers protection from bumps and dings and provides a positive grip in all weather conditions. The body is nitrogen filled and o-ring sealed-providing excellent water, fog and dust proofing.
