The Kowa 10x32 BD II XD Wide-Angle Binoculars provide the performance that avid birders, hunters, and world travelers demand without the bulk of full-sized models. To improve image quality and offset the light-gathering limitations of the smaller objectives, Kowa employs complementary technologies that include the use of PROMINAR extra-low dispersion glass, anti-reflection fully multi-coated optics, and highly reflective C3 and phase-correction prism coatings that work together to produce crisp, clear, and bright high-contrast images with accurate color rendition across the entire spectrum. Added to this performance is an exceptional short close-focus distance, an ultrawide angle of view, and a comfortable eye relief, which produce an immersive observational experience for any user. Designed for extensive outdoor use, the lightweight magnesium alloy chassis is wrapped in a protective rubber armor with a slip-resistant textured grip to provide secure handling in cold and wet conditions. To ensure a compact and highly packable form factor, Kowa utilizes Schmidt-Pechan prisms that allow for slimmer optical tubes but deliver the performance of conventional roof prisms. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature or humidity changes.
