The B&H Binocular Buying Guide

Featuring a high-definition optical system, a lightweight magnesium alloy housing, and powerful magnification for distant details, the 10x28 Diamondback HD Binoculars from Vortex are a versatile optic suited to a wide range of uses.

The Diamondback HD renders views with minimal chromatic aberration, exceptional color fidelity, edge-to-edge sharpness, and optimal light transmission through the use of high definition glass, an index-matched lens configuration, XR Plus lens coatings, and dielectric-coated, phase-correcting roof prisms. Minimum focus is a birding-friendly 6 feet. The lenses are protected from scratches, oil, and dust by ArmorTek exterior lens coating.

The housing is argon filled and sealed with O-rings to ensure reliable and durable protection against dust, debris, fog, and water. The binoculars are rubber armored to make them nonslip and offer durable protection. They are equipped with a large focusing knob that is easy to use even while wearing gloves. Naturally contoured to perfectly fit your hands, promoting comfort, and eliminating user fatigue, the Diamondback HD binoculars include a winning combination of features.
