Engineered with proprietary high-definition anti-reflection fully multi-coated optics and phase-corrected BAK4 prisms, Barska's black 8x42 Level HD Waterproof Binoculars present users with clear and crisp high-contrast views with accurate color representation with a field of view that approaches wide-angle. Complementing the optical performance are argon-filled and O-ring sealed optical tubes that provide water and fogproof performance in all temperature and weather conditions. To withstand the rigors of the trail, the chassis is wrapped in a protective rubber armor that is textured to ensure a secure slip-resistant grip. The combination of optics and construction details make the Level HD binoculars an ideal addition to your kit, whether you're in the woods, on the range, at the stadium, or sightseeing around town.
