Ideal for all your glassing needs on land and water, the Alpen Optics 8x42 Shasta Ridge Binoculars feature proprietary PXA phase-correcting prism coatings and HR metallic covered reflective prism surfaces that maximize light transmission and boost clarity and contrast. The prism coatings are complemented by anti-reflection fully multicoated optics which provide bright and clear high-contrast views with accurate color rendition. The 42mm objectives gather all the light needed to keep your wide-angle views crisp and bright in challenging conditions, such as at dawn and dusk, without being overly bulky or cumbersome. Its chassis is nitrogen filled and O-ring sealed to be resistant to internal fogging and waterproof to withstand extreme weather, and textured palm pads on the armor ensure a secure grip in cold and wet weather.
