Product Overview
Razor® HD binoculars are a cut above the rest, featuring unparalleled optics and uncompromising durability. Advanced optics combine with low-dispersion glass, multi-coated lenses and a coated prism to provide the clearest, sharpest, most colour-accurate image below flagship-tier pricing.
The apochromatic (APO) optical system and HD glass give exceptional colour sharpness, while extra-low dispersion glass increases resolution and colour fidelity. Multiple anti-reflective lens coatings maximise light transmission, and multi-layer prism coatings deliver crisp, colour-accurate images across a genuinely wide 362ft field of view at 1000 yards.
Ideal for long, tough hikes, the magnesium chassis, ArmorTek lens coating and rubber armor provide excellent protection in a compact design. A true open hinge and thumb-contoured barrels make one-hand operation genuinely comfortable, and the binocular is argon-gas purged for waterproof, fogproof performance in any conditions.
