Description
Featuring powerful magnification, a generous objective lens, and a close focus distance of just 5′, the 10×42 Diamondback HD Binocular from Vortex is a versatile optic suited to a wide range of uses. It comes with a Vortex GlassPak harness for comfortable use during hours of observation.
The Diamondback HD renders views with minimal chromatic aberration, exceptional color fidelity, edge-to-edge sharpness, and optimal light transmission through the use of ultra high definition glass, an index-matched lens configuration, XR Plus lens coatings, and dielectric-coated, phase-correcting roof prisms. The lenses are protected from scratches, oil, and dust by ArmorTek exterior lens coatings.
The housing is argon filled and sealed with O-rings to ensure reliable and durable protection against dust, debris, fog, and water. It is rubber armored for nonslip and durable protection and is equipped with a large focusing knob that is easy to use even while wearing gloves. Twist-down eyecups accommodate users who wear glasses. For hands-free use or the steadiest view, the Diamondback HD can be mounted on a tripod using the separately sold tripod adapter. Naturally contoured to perfectly fit your hands, promoting comfort and eliminating user fatigue, the Diamondback HD includes a winning combination of features.
