Product Overview
When you are glassing big country, you need reach and you need clarity. The Diamondback® HD 15x56 is built for exactly that. With 15x magnification and a large 56mm objective, this setup gives you the power to break down wide, open terrain without automatically reaching for a spotting scope.
The HD optical system delivers sharp detail and natural colour, with phase-coated and dielectric-coated BaK-4 prisms improving contrast and light transmission. Built for hunters who want serious reach without unnecessary bulk, the 15x56 rewards patient glassing with genuine long-range detail.
Built around a magnesium composite chassis wrapped in rubber armor, the 15x56 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. Pairing with a tripod is recommended for the best glassing experience.

Genuine strength and reduced weight for a binocular of this power.
