One look at the Viper compact binocular will convince you that few other binoculars of this kind can deliver low light performance with such bright, crisp images with exceptional colour transmission and still be lightweight.

Pick up the award-winning optics of the Vortex Viper in a tough, compact size - reliable in all conditions. XD (extra-low dispersion glass) objective lenses further enhance resolution and deliver the true-to-life colour accuracy so essential for identifying your subject.

The resolution of this premium, single-hinge compact will keep you scanning the landscape time and time again.


  • XD Lens Elements: Extra-low dispersion (XD) glass increases resolution and colour fidelity, resulting in crisp, sharp images.
  • XR Lens Coatings: Vortex proprietary XR anti-reflective coatings, fully multi-coated on all air-to-glass lens surfaces, increase light transmission for maximum brightness.
  • Dielectric Prism Coatings: Multi-layer prism coatings provide bright, clear, colour-accurate images.
  • Phase Correction: Used on roof prism models only—coating enhances resolution and contrast.


  • Roof Prisms: Valued for greater durability and a more compact size.
  • Waterproof: Optics are sealed with O-rings to prevent moisture, dust, and debris from getting inside the binocular.
  • Fogproof: Argon gas purging guarantees superior fogproof and waterproof performance.
  • Rubber Armour: Provides a secure, non-slip grip, and durable external protection.


  • Adjustable Eyecups: Twist up and down for precise, intermediate settings to maximise comfortable viewing with or without spectacles.
  • Center Focus Wheel: Adjusts the focus of both binocular barrels at the same time.
  • Right Eye Diopter: Adjusts for differences in a user's eyes. Located on the right eyepiece.
