The Viper HD a premium-quality binocular packed with everything you need and nothing you don't. Rugged, compact and lightweight (one of the lightest full-size binoculars to date), it's easy to see why the Vipers are award winners. Add in HD (High Density) extra-low dispersion glass for impressive resolution and color fidelity and the Vipers change more than the game. They change the results, too.
HD (High Density) extra-low dispersion glass delivers impressive resolution and color fidelity, resulting in High Definition images. XR Plus fully multi-coated premium proprietary coatings deliver the highest level of light transmission with multiple anti-reflective coatings on all air-to-glass surfaces for maximum brightness. Dialectic prism coatings provide bright, clear, color-accurate images.
A magnesium chassis decreases weight and increases strength. The O-ring seals prevent moisture, dust and debris from penetrating the binocular for reliable performance in all environments. Argon gas purging prevents internal fogging over a wide range of temperatures, while ultra-hard, scratch-resistant coating protects exterior lenses from scratches, oil and dirt.
