The Vortex Diamondback HD 10x42 binoculars are built for hunters, birders, and outdoor enthusiasts who demand hard-working, reliable optics with sharp resolution, enhanced contrast, and rugged durability. With 10x magnification and 42mm objective lenses, they deliver exceptional light-gathering capability for use at dawn, dusk, and throughout the day without adding excessive weight or bulk.

The HD optical system uses select glass elements to cut chromatic aberration and provide outstanding color fidelity and edge-to-edge sharpness. Fully multi-coated lenses apply anti-reflective coatings to all air-to-glass surfaces for maximum light transmission, while phase-corrected dielectric prism coatings boost reflectivity to over 99% for bright, color-accurate images. ArmorTek exterior lens coatings resist scratches and abrasions while repelling oil, dirt, and sap for easy cleaning. The argon-gas purged, O-ring sealed design ensures waterproof and fogproof performance across all weather conditions.

Twist-up click-stop rubber eyecups with 15mm eye relief accommodate comfortable viewing with or without eyeglasses. The true open hinge design reduces weight and bulk while improving ergonomics, and a large center focus wheel adjusts both barrels simultaneously. The 4.2mm exit pupil and 330-foot field of view at 1000 yards make tracking moving subjects effortless. The magnesium alloy chassis wrapped in rubber armor provides a secure, non-slip grip and impact resistance. A tripod adapter thread allows hands-free use. The binoculars weigh 21.3 oz and measure 5.7" x 5.1". Covered by Vortex's Unlimited, Unconditional Lifetime VIP Warranty. Includes GlassPak Binocular Harness, Comfort Neck Strap, Tethered Objective Lens Covers, Rainguard Eyepiece Cover, and Lens Cloth. Model DB-215.
