Nikon 8x42 ProStaff 3S Binocular features silver-alloy-coated roof prisms and anti-reflection multi-coated optics that produce bright and clear high-contrast images with true color rendition across the entire field of view. Its 8x magnification brings subjects up close, but without the noticeable hand shake often associated with higher power optics, while the 42mm objectives boost its light-gathering ability to improve views in challenging light such as at dawn and dusk or in foggy and cloudy weather. With the combination of prisms, optical coatings, a respectable angle of view, and an exceptionally 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 this binocular durable and comfortable to use. It has a lightweight and durable reinforced polycarbonate resin chassis, and is protected by black rubberized armor that is accented with textured palm pads to give it a secure non-slip grip. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and submersible, as well as resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A tethered one-piece ocular rainguard covers the eyecups as the binocular hangs around the neck and prevents rain and spraying water from filling them, and the objective lens caps can clip onto the neck strap to keep them safe from blowing overboard or being lost on the forest floor. Whether you're hunting or birding, boating or watching your favorite team, this ProStaff will quickly become indispensable for all your outdoor activities.
