  • Phase-Corrected and Dielectric Coated
  • XR Fully Multi-Coated Optics
  • Scratch-Resistant ArmorTek Lens Coating
  • Wide 66° Apparent Angle of View


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 maximise light transmission through the light path and improve contrast and colour rendition across the entire visual spectrum. The compact roof prisms are dielectric coated. Phase-corrected coatings limit internal interference, light loss, and diffraction while maximising light transmission through the prism system. These features work together to produce bright, sharp, and clear high-contrast views with accurate colour 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 rigours 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.

Key Features:

Optical Performance
  • Powerful 12x magnification brings subjects in for close observations at extreme distances
  • Large 50mm objective lenses help maintain image brightness at long range despite the high power and provide generous light-gathering capability for improved vision in challenging conditions
  • Compact roof prism light path enhances performance while helping to keep the weight and bulk down
  • Phase-correcting prism coatings eliminate internal interference to improve colour and contrast
  • Dielectric prism coatings boost internal prism reflectivity to greater than 99% to maximise light transmission through the prism with minimal loss and diffraction
  • High-density (HD), extra-low-dispersion (ED) glass lens elements reduce chromatic and spherical aberrations for increased contrast and improved colour rendition and sharpness without distortion across the entire field of view
  • Proprietary XR anti-reflection fully multi-coated optics increase light transmission for accurate colour fidelity and improved contrast and clarity
  • ArmorTek exterior lens coatings resist scratches and abrasions while allowing oil, dirt, and sap to be cleaned off without leaving smudges or residue
  • Wide 66° apparent angle of view helps to reduce the appearance of the distracting hand shake that is common when holding high-power optics such as this
  • 288-foot field of view at 1000 yards
Use and Handling
  • Closed bridge configuration provides a solid platform for the internal focusing mechanism
  • Large slip-resistant centre focus knob is easy to manipulate in cold and wet weather or while wearing gloves
  • Locking right eye dioptric correction lets you compensate for individual eye prescription for tack-sharp views
  • 56-75 mm interpupillary distance range allows easy viewing by a wide variety of users
  • Twist-up click-stop rubber eyecups for comfortable use with or without eyewear
  • Tripod mountable with an optional adapter for hands-free use to reduce vibration and arm fatigue
  • 16mm eye relief reduces eye strain to make for more comfortable viewing, especially over extended periods
  • 4.1mm exit pupil will completely cover most pupils as they open and dilate in low light to ensure the whole scene remains in view without vignetting
Construction Details
  • Lightweight and impact-resistant polycarbonate chassis
  • Chassis material is temperature resistant, limiting the expansion and contraction that can occur with metal materials. preventing optical components from moving out of alignment over time
  • Rubber armouring provides protection from bumps and impacts while offering a positive slip-resistant grip in cold and wet weather
  • Argon-filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature or environmental conditions
  • Tethered objective lens caps and one-piece ocular rainguard protect the lens surface without the fear of losing them when not in use
  • GlassPak binoculars harness holds the optic close to your body to keep them safe and secure without swinging or hanging when moving or climbing over rough terrain
