Superior quality full-sized Pentax SD 10x42 WP Binoculars are ideal for the widest range of lighting and weather conditions. Exceptional quality meets high-end expectations. Large objective lenses incorporated in the design allow for contrast-rich, bright viewing under all light conditions. New lens coating is a high-grade, multi-layer coating that reduces reflectance in the visible light spectrum, allowing the user to view crisp, high-contrast images free of flare and ghosting, even under demanding lighting conditions. It gives long eye relief for comfortable viewing with or without glasses. The waterproof and nitrogen-filled (JIS Class 6) is to handle the most extreme weather conditions (submersible to 1m).
