Product Overview
Made for hunters who demand hard-working, reliable optics, the Diamondback® HD 12x50 delivers sharp resolution, enhanced contrast and rugged durability. The combination of 12x magnification and a large 50mm objective genuinely suits plains game and open-country viewing where distance and detail both matter.
The HD optical system is optimised with select glass elements to deliver exceptional resolution, cut chromatic aberration, and provide outstanding colour fidelity, edge-to-edge sharpness and light transmission. Dielectric prism coatings and phase correction combine to deliver bright, clear, colour-accurate images at extended distances.
Built around a magnesium composite chassis wrapped in rubber armor, the 12x50 is argon-gas purged and O-ring sealed for genuinely superior fogproof and waterproof performance, with a hydrophobic ArmorTek coating protecting the outer lens elements from scratches, oil and dirt.
