Vortex 10x50 Diamondback Roof Prism Binoculars

The Vortex 10x50 Diamondback Roof Prism Binoculars provide superior optical performance with rugged waterproof construction. These binoculars feature a lightweight and tough rubber armored build along with Vortex Optics' fully multi-coated glass lens design to deliver some of the highest performance images on the market for an amazing low price. This pair of optics offer up to 10x magnification and ultra-wide field of view of 315 feet at 1,000 yards – making them suitable for large to mid-range activities. These binoculars will bring you closer to the action than ever thought possible.

Optical Features

The 10x50 Diamondback utilizes an HD Optical System which is optimized with select glass elements that deliver an exceptional resolution with reduced chromatic aberration to give you true color fidelity with edge-to-edge sharpness. The multiple anti-reflective coatings increase light transmission giving you detailed imagery even at low-light surrounding. Diamondback Binoculars have a multi-layer dielectric prism coating that provides bright, clear, color-accurate images while phase correction coating enhances the roof prism's resolution and contrast.

Sturdy Construction

The Vortex 10x50 Diamondback is extremely lightweight yet tough enough to last through the harshest elements. Thanks to O-ring seals and Argon gas purging, these binoculars offer complete waterproof and fogproof performance. O-ring seals prevent moisture, dust, and debris from penetrating the binoculars’ barrel for ultimate protection, while Argon gas purging prevents internal lens fogging at varied temperature. A rubber armored exterior ensures a secure, non-slip grip for maximum comfort.

Convenient to Use

Vortex 10x50 Binoculars feature adjustable twist-up eyecups that maximize your comfort even when you are wearing eyeglasses, while a diopter located on the right eyepiece adjusts for differences in a user's eyes. The center focus wheel lets you simultaneously adjust the focus of both binocular barrels. For added convenience, you can also mount these binoculars on a tripod or car window mount using an optional tripod adapter.

Vortex 10x50 Diamondback Roof Prism Binoculars SKU: DB-206

Rated 5 out of 5 by from Very happy! I bought these as a gift and am totally happy with the quality of this product, the fast shipping and pleasant interaction with this comapny. !00% recommend!

Rated 5 out of 5 by from Excellent Optics!! Excellent performance and ergonomics. Tack sharp images with little to no chromatic aberration over the entire field over view. Excellent low light performance. I use these binoculars for serious birding under low/poor lighting and they deliver every bit of the same performance as the Razor HD models for less money investment. I'm very hard pressed to see any difference between these and a competitor's ED binoculars. These will be used for bird watching during the dawn and dusk hours as well as for some astronomical viewing of the brighter deep sky objects. A fantastic addition to my binocular collection!!

Rated 5 out of 5 by from Great Binos I have used these for two seasons and they work really well for scanning heavy cover out to 300 meters particularly in low light situations.

Rated 5 out of 5 by from So nice I bought 2 My wife and I decided to go to Alaska on a land and sea cruise. We went to our local big box outdoor store and looked at the options. We had planned on sharing a "really nice" set of binoculars. After comparing our options, we walked out with 2 sets. When in Denali, on a tour, we watched a grizzly bear and her 3 cubs clearly eating blueberries. We were also able to make out Dahl sheep at extremely long range and seals and otters in glacier bay. I cant speak to the warrantee because I haven't had any issues, but as for the clarity of the optics, it is exceptional for the price.

Rated 5 out of 5 by from The. Best. Not only are the 10x50's giving you amazing views, their warranty ain't too bad either!! My binos fell off of a shelf and they landed on the strap loop, cracking it off. When I called, the woman was so helpful and I sent them back for possible repair. A week later, they sent me a NEW pair because they couldn't fix the strap loop. Worth every penny!!

Rated 5 out of 5 by from Great product We had a pair of vortex and lost them in a devastating house fire. We eagerly replaced our binoculars with more vortex and this site made it a quick and easy process.

Rated 5 out of 5 by from Prompt and honest The 10x42 Diamondback HD is everything it advertised it would be. Focus Camera is an honest dealer. Delivery was almost instantaneous and all the parts were complete. I recommend Focus Camera to all 100%. Thanks. I wish your company success!
