The Kowa 8x33 Genesis 33 PROMINAR XD Binoculars strike an ideal balance between power and portability with moderate magnification and objective lenses that push them almost into the full-size category. To improve image quality and boost the light gathering abilities are complementary technologies that include the use of PROMINAR extra low-dispersion glass, anti-reflection fully multi-coated optics, highly reflective C3 prism coatings, and phase-corrected prism coatings that work together to produce crisp, clear, and bright high-contrast images with accurate color rendition. Added to this performance is a wide apparent angle of view and a long eye relief, which produce an immersive observational experience for any user. Designed for extensive outdoor use, the aluminum alloy chassis is wrapped in a protective rubber armor, and the body is ergonomically designed to offer a comfortable feel in the hand with a secure, slip-resistant grip. 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. Tethered objective lenses and a one-piece ocular rainguard ensure that the lenses stay protected while being near at hand for fast use.
