Hunters can bank on Nikon's legendary Extra-Low Dispersion glass to deliver astonishing sharpness and state-of-the-art color correction for unparalleled detail resolution in low-light and low-visibility conditions. These top-of-the-line binoculars represent the cutting edge of optical technology and precision. Advanced, fully multicoated nonreflective lenses designed to eliminate chromatic abberations for vivid, high-contrast images with flare-free, razor-sharp clarity. Dielectric-coated prisms produce remarkably brighter views even under dense canopies and cloud cover. The stalwart magnesium-alloy body cuts weight and increases durability, while making it easy to maintain steady, freehand observations for longer periods of time. Ergonomic quadrangle construction promotes balance and fits perfectly in your hands; open-bridge styling comfortable for extended viewing. Horn-shaped eyecups block out peripheral light promoting a clear field of view. Dual focus knob with locking diopter adjustments centralizes focusing functions to increase speed, performance and convenience when seconds count. O-ring sealed and dry nitrogen-filled for unbeatable waterproof and fogproof performance, even during the harshest conditions.
