With a magnification-objective lens configuration favored by outdoor enthusiasts and outfitted with a wide field of view and generous eye relief, the Kowa 10x42 SV II Binoculars provides reliable performance from dawn through dusk and in all weather conditions. To deliver its performance, Kowa employs anti-reflection fully multi-coated optics, phase-correction prism coatings, and oil-resistant exterior lens coatings that work together to keep the lenses clean and produce crisp, clear, and bright high-contrast images with accurate color representation. Added to this performance is a wide angle of view that allows you to see wide swaths of the landscape before you without having to turn your head while also reducing the appearance of the distracting hand shake often associated with holding high-power optics such as these. Complementing the optical performance are construction details that make this binocular durable and comfortable to use. It has a lightweight polycarbonate chassis and is protected by rubberized armor that gives it a secure non-slip grip even in cold and wet conditions. 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 binocular hangs around the neck and prevents rain and spraying water from filling them, and it attaches to the included neck strap to prevent it from being lost on the forest floor.
