About the Vortex Optics 8.5 Roof Prism

The Vortex 8.5x50 Diamondback binocular's superior quality; high-performance hunting optics can find their way around your neck. Boasting large, light-grasping objectives along with greater viewing power delivered by 8x optics, the 8.5x50 Diamondback lets you close in on details missed by others at this time of day. This Diamondback rattlesnake rugged binocular is striking in how well it detects life in low light. Huge field-of-view enhances fully multi-coated optics, phase-corrected prisms, waterproof/fogproof construction, soft tapered eycups and rugged rubber armor.

You can trust the rock-solid performance of the Diamondback binocular across rocky, sand-carved terrain, or into the high timber of the rockies. The Diamondback's protective rubber coating gives you a sure grip that is easy to handle, even as fingers grow numb in the cold. The retractable Diamondback eyecups feature a soft, tapered style for a more natural fit at your eye - cushioned with rubber for years of relaxed viewing.
