Vortex 8x42 Diamondback HD Binoculars Featuring a generous objective lens, a wide field of view, and a close focus distance of just 5 feet, the Vortex 8x42 Diamondback HD Binoculars are a versatile optic suited for a wide range of uses. They include a Vortex GlassPak harness for comfortable, extended observation sessions. The Diamondback HD delivers sharp, bright, and color-accurate views with minimal chromatic aberration, thanks to its ultra high-definition glass, index-matched lens configuration, XR Plus lens coatings, and dielectric-coated, phase-correcting roof prisms. The ArmorTek exterior lens coating protects against scratches, oil, and dust. The argon-filled and O-ring-sealed housing ensures waterproof and fogproof performance, while the rubber armor provides a durable, non-slip grip. A large focus knob enables easy adjustments even when wearing gloves, and twist-down eyecups make it comfortable for eyeglass wearers. For hands-free use or extra stability, the Diamondback HD can be mounted on a tripod with an optional adapter. Its ergonomic design ensures a natural fit and reduced user fatigue.
