The Kowa 6.5x32 BD II XD Wide-Angle Binoculars have a lower magnification than you typically see, but therein lies their strength: The lower magnification helps to produce the long eye relief and wide exit pupils that are usually short and narrow, respectively, resulting in a more comfortable user experience with brighter and clearer views in low light. 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, bright high-contrast images with accurate color rendition across the entire spectrum. Added to this performance are an exceptionally short close-focus distance and a wide angle of view, which produce an immersive observational experience for every 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 binoculars utilize 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.
