Nikon 8x42 Monarch HG Binoculars

Taking their place at the top of Nikon's flagship series - 8x42 Monarch HG Binoculars are engineered with complementary technologies to produce an optic that is built to perform in low light and the harshest conditionsFirst is the use of lead- and arsenic-free extra-low dispersion (ED) glass in the lens elements to correct chromatic and spherical aberrations Next are phase-corrected and dielectric-coated roof prisms - which further limit internal light loss and interference and improve image contrast The optical path is fully multi-coated with anti-reflection coatings - which increase light transmission - image contrast - and sharpness and provide true color rendition Finally is the use of Nikon's field-flattener system - which eliminates the distortion common at the lens edges - producing crisp details along the far periphery of the wide field of view This all translates to bright and clear - high-contrast images with accurate color across the field of view&mdashespecially at low light such as early morning and late evening - and under heavily overcast skiesThe chassis is built with a short bridge design - which presents more gripping surface and helps to reduce the overall weight Made to survive use outdoors - the optical tubes are nitrogen filled and O-ring sealed to make them not only fogproof when moving between extreme temperature changes - but also waterproof and submersible The exterior has textured - rubberized panels that protect against knocks and drops and offers a slip-resistant grip for sure handling in cold and wet conditions Nikon includes tethered objective lens covers and ocular rainguard to ensure they cannot be lost easily and are ready
