Updated from the original model with a lighter weight and sleeker styling, the Alpen Optics 8x42 New 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. Its 42mm objectives gather all the light needed to keep your views crisp and bright in challenging conditions, such as those 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 an IPX7 rating that enable it to withstand extreme weather.
