Nikon's 8x42 Monarch 7 ATB Binoculars are outfitted with anti-reflection, fully multicoated, extra-low dispersion glass elements and highly reflective dielectric-coated and phase-corrected roof prisms, to produce bright and clear high-contrast images with accurate color rendition and minimal color fringing across the entire field of view. Their 8x magnification brings subjects up close, without sacrificing the field of view or exit pupil, or the noticeable hand shake often associated with higher power optics, while the 42mm objectives boost their light-gathering ability to improve views in challenging light such as during the predawn and late evening hours or in foggy and cloudy weather. With the combination of spacious field of view; glass, prism, and optical coatings; and long eye relief, users can enjoy a comfortable and immersive observational experience in most lighting conditions.Complementing the optical performance are construction details that make these binoculars durable and comfortable to use. They have a lightweight and durable reinforced polycarbonate ATB chassis and are protected by rubberized armor that is accented with indented palm rests to give them a secure non-slip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A one-piece ocular rainguard covers the eyecups as the binoculars hang around the neck and prevent rain and spraying water from filling them, and the objective lens caps are also tethered to keep them safe from being lost on the forest floor. The exterior lens surfaces are treated with a clear armor coating that helps to prevent scratches and abrasions, while allowing dirt, debris, oils, and saps to be more easily cleaned off without leaving residues.
