Product Overview
Viper® HD delivers outstanding clarity, rugged durability, and the versatility to keep up with hunters and guides who embrace tough, unpredictable conditions. With sharp resolution that brings every detail into focus and a lightweight, ergonomic build that won't wear you down, Viper® HD gives you the upper hand — ready to glass longer and move farther without missing a thing.
High-density, extra-low dispersion (ED) glass elements deliver genuinely improved colour fidelity and resolution over the Diamondback HD tier, backed by phase-corrected and dielectric-coated prisms and XR fully multi-coated optics for maximum light transmission. ArmorTek scratch-resistant coating protects the exterior lenses from scratches, oil and dirt.
Built on a lightweight polycarbonate chassis — a genuine, honest tradeoff of some rigidity for a real weight saving — the 10x42 is argon-gas purged and O-ring sealed for waterproof, fogproof performance. A locking diopter and true open hinge round out a binocular genuinely trusted by serious hunters and guides.
