With the compact 10x28 Diamondback binoculars, light doesn't find its way in so much as it's grabbed, bound, gagged, and made to serve your will.

•Phase corrected prisms (increasing light transmission by 7%) deliver sharp, greatly contrasted images.
•BaK-4 prisms provide sharp images from one edge of the broad viewing field to the other.
•Fully multi-coated optics increase light transmission for higher image quality in all lighting conditions—enhanced for 2009.

A rock-solid performer

Whether your adventure takes you across rocky, sand-carved terrain, or into the high timber of the Rockies, you can trust the rock-solid performance of the Diamondback binocular. The Diamondback's protective rubber coating gives you a sure grip that is easy to handle, even as fingers grow numb in the cold. In addition, 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.

•Complete waterproof protection keeps dust and water out of the optical system with tight O-ring seals.
•Complete fogproofing of internal lenses with argon-purged optics presents clear views in spite of sudden temperature changes.
•Diamond checker pattern in protective rubber armor provides a solid-grip surface.

Argon gas purging
This advanced process protects your Diamondback binocular in the following ways:
•Argon gas does not absorb or react chemically with water.
•Argon gas eliminates internal fogging.
•Argon gas maintains its protective properties over a wider temperature range.
•Argon gas does not diffuse as quickly as other elements, extending the service life of the optics longer.

Included with the Vortex Diamondback 10x28 Binocular:
•Rainguard
•Tethered objective lens covers
•Comfort neck strap
•Deluxe padded carry case
•Vortex VIP Lifetime Warranty
