VORTEX 12X50 DIAMONDBACK HD BINOCULARS DB-217 + PROFESSIONAL CLEANING KIT Vortex 12x50 Diamondback HD Binoculars Featuring powerful magnification and a large 50mm objective lens for bright, detailed viewing even in low light conditions, the Vortex 12x50 Diamondback HD Binoculars are a versatile optic suitable for birding, nature observation, and outdoor exploration. They include a Vortex GlassPak harness for hands-free carrying and can be mounted on a tripod using an optional adapter. The Diamondback HD delivers superior optical performance with minimal chromatic aberration, exceptional color fidelity, edge-to-edge clarity, and optimal light transmission. This is achieved through ultra-high-definition glass, an index-matched lens system, XR Plus coatings, and dielectric-coated, phase-corrected roof prisms. The ArmorTek coating protects external lenses from scratches, oil, and dust. The housing is argon-filled and O-ring sealed for waterproof and fogproof performance. Its rubber armor provides durability and a non-slip grip, while the large central focus knob ensures easy adjustment even when wearing gloves. Twist-down eyecups make it comfortable for users with or without glasses. Ergonomically contoured for comfort and reduced fatigue, the Diamondback HD combines performance and reliability.
