Vortex did a great job with these Diamondback binoculars.

Vortex did a great job with these Diamondback binoculars. I've been super happy with mine. They have great image quality, functionality, and durability. They're also nicely lightweight and easy to carry/use in the field. I don't go on a hunting trip without them. I've never been let down by any Vortex optics product I've tried, and these Diamondbacks are no exception. Would happily buy them again, and would happily recommend them to others in the market. Good to go!

perfect for glassing.

Vortex makes quality products. This is a great starter bino to get into glassing animals for hunting and even wildlife watching. Image quality is decent and has a great zoom. Recommended.

Excellent glass and size

Really great optics and perfect size for a 10 power binocular. Great for elk hunting out west, or glassing whitetail from a tree stand. Perfect size to weight ratio.

Older Eagle Optics Binoculars Replaced

My beloved Eagle Optics binoculars needed repair- Vortex is now covering the warranty for EO. I sent out to Vortex (they supplied a prepaid label) and a few weeks later I receive a brand new pair of Diamondback HD binoculars! Whaat?? Amazing customer service and communication. Looking forward to my next birding adventure with my new binos!

Great for the price

Affordable, Nice Clarity, Hard to justify spending anymore money for minimal additional performance. For the size of the Binos I was underwhelmed with the performance but that has little to do with vortex and more to do with this class of Binos in general.

Voters optics rock

The quality of the optics is second to none. I've tried other optics for scopes and optics, but the difference is simply astounding. Vortex gets my vote every time. Have you ever taken a picture with a lesser quality camera then taken the same picture with a superb camera? I have. The image captured is night and day difference. Vortex is my first go-to always. Furthermore, the support they provide is superb. You can't go wrong with Vortex.

I've relied on the Vortex

I've relied on the Vortex Optics - Diamondback HD 10x50 binoculars for countless hunts and outdoor excursions across Africa and throughout the USA, and they've consistently delivered outstanding performance. These binoculars are a perfect blend of clarity, durability, and ease of use. The HD lenses provide incredibly sharp, bright, and clear images, even in low-light conditions like dawn and dusk when game is most active. The 10x magnification combined with a 50mm objective lens strikes an ideal balance, offering excellent detail without sacrificing field of view or brightness. Despite their powerful optics, the Diamondback HDs are surprisingly lightweight and comfortable to hold for extended periods. The rugged construction means they're built to withstand tough environments-whether it's the dusty plains of Africa or dense forest in the USA. They're also waterproof and fog-proof, giving me confidence in all weather conditions. The focus mechanism is smooth and precise, allowing quick adjustments when tracking moving game or scanning the landscape. The rubber armor provides a secure grip and extra protection against bumps and drops. If you're looking for high-quality binoculars that deliver crisp visuals and durable performance, the Vortex Diamondback HD 10x50 is an excellent choice. They're dependable, versatile, and have earned a permanent place in my gear for every outdoor adventure.

Better than the expensive Binoculars

I purchased the much lauded, expensive Zeiss 8x42. I returned them and bought a pair of Vortex 8x42 for 2/3 less. They are Lighter, Tighter and Brighter! There is a lot of cloud cover this Spring in New England. I think they will be good with their wide angles for a little star gazing. So far, they have been superb looking at the trees and the Atlantic. Where are the striped bass? I hope to see the shore birds swooping down to reveal the bigger fish. I plan some birding too. So far, they are the best binoculars I have ever looked through.

My First Foray into Higher-End Binocular Segment

I hope everyone at Vortex is healthy and happily employed! I purchased the Diamondback HD 8x42 binocular SKU DB-214 last September at the CT Bridgeport Bass Pro - Cabelas store, what I consider an 'investment' buy - as in - a binocular kit FOR LIFE. And I was not disappointed. I already own a dozen binoculars, large 7 to 10x50s, zoom models, intermedate 8x40s, and car glove-box duty 8x25 pieces. All decent stuff, until the Diamondback bit. . . Construction: Very HEAVY for it's size and magnfication class. All adjustments required actual effort, and stayed put until I needed to adjust again. Not a flimsy piece of material anywhere to be found. The ocular shades click between different settings, for regular users and those wearing eye/sunglasses. All lens movement is internalized inside the twin barrels, as in, no external bridge holding the optics to the objective lenses to bend or crush. The VIEWWWW: Stunning, both by day and by night. Bright and crystal clear, I forgot I was looking through them until I lowered them to my chest via the included strap. The Accessories: Handy carry bag, although the neck strap took me no less than 45min. to feed through the various openings to attach it to the carry bag. Lens caps stay with the binocular, but hang out of the way if you take the time to attach them correctly. Quality-feel dust cloth for wiping lenses. Overall: As I previously referred to these as an investment, they are a big step for me into the mid-upper end scale of sports & rec. optics. Approaches Swarovski caliber without the stratospheric price, but still head and shoulders above familiar brands (Canon, Bushnell, Nikon, etc. ) A general statement about binoculars, regardless of one's price point or preferred brands: Among the inventory at the store I purchased the Diamondbacks, I noticed only 3 binoculars with a magnification less than 10X, including this model that I bought. All others were 10X, 12X, or higher, even glove-box sized models with only 20-25mm objective lenses. I realize that people nowadays are of the 'more is better' mentality about just every facet in life: louder speakers, brighter TVs, more air in their tires. And, higher magnefication in binocs and other optics. Not always the case. I find the best experiences with hand-held optics to be at magnification factors of 7 up to 10x, max. Binoculars of 11X and up can be appreciated only via a tripod or other support structure. It just gets too shakey over 10x for practical observing purposes. Please continue to offer binoculars with sensible magnfications, such as 7x to 10x, for us vintage users! And thanks for producing such high quality products.

Great binoculars.

These binoculars have very clear glass, are easy to focus and are a compact size for the power. Great for nature watching while on a hike or just looking out your back door. Comes with usual neck strap and lens covers but also comes with a nice case to help protect when not in use. Would recommend to anyone looking for a pair of binoculars on the compact size end with a good amount of magnification.

Trust Vortex products and unsurpassed warranty.

I just returned a pair of Vortex binoculars that my wife purchased for my birthday at least 12 years ago. I had great use from these but about two months ago, I was not able to use them as the right side was completely fogged up and not functional. I contacted Vortex and I was told that Vortex would either fix them or issue me a new pair. About two weeks later I was sent a new pair of Diamondback HD 10 X 42 binocular. I love these binoculars and love the company even more. Vortex is true to their warranty. I did not even have to pay for shipping as they sent me a shipping label. You can bet that any future purchases of binoculars or scopes or any product I can use that Vortex offers, I will only purchase from Vortex. Great products and a true lifetime warranty.

Better than I hoped for

My first replacement for a 15+ year old pair of 16x50 Bushnell I use for bird watching on the lake. Very surprised at how clear it is with good light. Above average at low light. The adjustable eye cups allow me to keep my eyeglasses on which greatly improves image. And despite the the reviews if I remain sitting the shaking is minimal. Great for deer or hog size slow moving animal spotting at 500 yards.

I bought these binoculars about a month and a half ago and I?ve used them several times, and I love them! They are great quality for the price !!

How can you elevate your outdoor viewing experience With the 12x50 Diamondback HD Waterproof Roof Prism Binocular, you can immerse yourself in the beauty of nature with unparalleled clarity and precision. This high-performance binocular is meticulously engineered to redefine the balance between cost and quality, outperforming its competitors in delivering a superior optical experience.

The Diamondback HD is equipped with an advanced HD Optical System, carefully optimized with select glass elements to deliver exceptional resolution. This system significantly reduces chromatic aberration and provides outstanding color fidelity, ensuring every view is a vivid spectacle. Experience edge-to-edge sharpness and superior light transmission that brings your surroundings to life.

Each air-to-glass surface of this binocular is fully multi-coated with multiple anti-reflective coatings, significantly enhancing light transmission for brighter, clearer images. The dielectric multi-layer prism coatings further amplify image quality, ensuring bright, clear, and color-accurate visuals.

The exterior lenses are safeguarded by ArmorTek, an ultra-hard, scratch-resistant coating that protects against scratches, oil, and dirt. This ensures your binoculars maintain their high-quality performance, even in challenging environments. The rugged rubber armor construction offers a secure, non-slip grip and durable external protection, making the Diamondback HD a reliable companion for all your outdoor adventures.

Featuring waterproof construction with O-ring seals, this binocular prevents moisture, dust, and debris from penetrating, ensuring reliable performance in all environments. It's also shockproof, with a rugged construction that withstands recoil and impact. Fogproofing is achieved through Argon gas purging, preventing internal fogging over a wide range of temperatures.

The roof prism design adds to the binocular's durability and compact size. Adjustable eyecups twist up and down for comfortable viewing with or without eyeglasses. The center focus wheel simultaneously adjusts the focus of both binocular barrels, while the diopter adjusts for differences in a user's eyes, located on the right eyepiece.

For added convenience, the binocular is tripod adaptable, compatible with a tripod adapter for use on a tripod or car window mount. The included GlassPak binocular harness keeps your binoculars close at hand, ready to deploy at a moment's notice. It provides protection and significantly more comfort than traditional neck straps.

Whether you're birdwatching, hunting, or observing wildlife, the 12x50 Diamondback HD Waterproof Roof Prism Binocular is your perfect partner, offering high-powered, waterproof, and rugged performance. This bundle also includes a portable telescoping stool/chair and a cleaning cloth, ensuring you're fully equipped for your next outdoor adventure.
