  • Our take on the Vortex Viper HD 10x42 Roof Prism Binoculars

    The Vortex Viper HD 10x42 is a roof-prism binocular built for hunters and general outdoor use. It pairs HD extra-low dispersion glass with XR Plus fully multi-coated lenses and dielectric-coated, phase-corrected prisms for bright, color-accurate images and solid low-light performance. At about 25 oz with 17 mm of eye relief and a 6.5 ft close focus, it sits between budget glass and top-tier alpha binoculars, and owners generally rate its optics well above its class. The trade-offs are a narrow 6.5-degree field of view and a focus wheel some users find stiff when new.

    • Focus wheelMixedSome owners find the focus wheel stiff when new, though most say it smooths out with use.
    • Build and weather sealingPraisedUsers describe it as rugged, waterproof and fogproof, holding up in rain and cold.

    About the Vortex Viper HD 10x42 Roof Prism Binoculars

    The Vortex Viper HD 10x42 is a roof prism binocular with 10x magnification and 42 mm objective lenses. It uses HD (High Density) extra-low dispersion glass for resolution and color fidelity. XR Fully Multi-Coating is applied to all air-to-glass surfaces to increase light transmission, and the prisms have multi-layer dielectric coatings and a phase correction coating for brightness, color accuracy, resolution and contrast.

    Waterproof O-ring seals keep moisture, dust and debris out, and argon gas purging prevents internal fogging over a wide range of temperatures. ArmorTek, a hard, scratch-resistant coating, protects the exterior lenses from scratches, oil and dirt. The rubber-armored body gives a non-slip grip, and the short-hinge design is meant to improve handling and ergonomics.

    The eyecups move up and down and stop at intermediate settings, so the binoculars can be used with or without eyeglasses. A center focus wheel adjusts both barrels at once. A locking diopter on the right eyepiece adjusts for differences between the user's eyes. The binoculars can be mounted on a tripod or a car window mount with a tripod adapter.
