This updated 2018 version of the Vortex Viper HD 12x50 Binoculars get upgraded with a significantly wider field of view, angle of view, and interpupillary distance adjustment range from the previous iteration to make views more spacious and viewing through them easier and more comfortable for a wide variety of users.

Optically, these binoculars benefit from proprietary XR anti-reflection fully multicoated optics that maximize light transmission through the light path and improve contrast and color rendition across the entire visual spectrum. The compact roof prisms are dielectric coated. Phase-corrected coatings limit internal interference, light loss, and diffraction while maximizing light transmission through the prism system. These features work together to produce bright, sharp, and clear high-contrast views with accurate color fidelity and crisp resolution. The powerful magnification is designed for observing large game at extreme distances such as in the wide-open spaces of the American West. Large 50mm objective lenses draw in generous amounts of light to offset the dimming that can happen with high-power optics and maintain bright and crisp images even when conditions are less than ideal.

Complementing the optical performance are construction details that allow the Viper HD to withstand the rigors of the trail. The optical tubes are argon filled and O-ring sealed to be waterproof and resistant to internal fogging if the weather turns or they take an accidental spill in a stream or puddle. Protecting the optical components is a polycarbonate chassis that is lightweight and durable as well as resistant to the expansion and contraction that metal suffers from and which can lead to fuzzy views over time. Vortex includes a GlassPak binocular harness case that protects the optic when not in use while keeping it close to your body, preventing swinging and swaying as you move or climb over rough and rocky terrain. Objective lens caps and a one-piece ocular rainguard protect the exterior lens surfaces. To keep the caps and rainguard safe during use, they are tethered to the body and strap, respectively.
