2023 model.

I bought these back a few years ago thru expertvoice. Vortex is definitely in a class of their own. Twice these have taken major spills amd vortex was more than happy to check them out and fix what is broken. These are tough built model. I hunt washington and idaho. I dont have any issues with early morning fogging or dusty lenses. I love the diamondback series.

Vortex Diamondback 12x50 Binoculars

I have loved these binoculars. I have glassed multiple times with these and have loved it each time. Obviously since these are the lower quality binoculars at times at greater distances they can be SLIGHTLY blurry but I mean barely noticeable. The glass is super clear and I will definitely be using these as long as I can. They are great. The harness is honestly comfortable to wear as well. These are great starter binos.

Vortex customer service rocks.

I lost my eyecup to my 4 or 5 year old Vortex binoculars. I called. Talked to an actual person who actually helped solve my problem without being transferred four times. Parts arrived in a week. Amazing. Vortex customer service rocks.

Fantastic Glass

When in comes to value in optics- Vortex is tough to beat. Bought these nocs for hunting and work use. Crystal clear optics, comfortable to use and small enough to stow in a pack. Fantastic item.

Vortex has always had good

Vortex has always had good glass at a very competitive price point. Purchased these as a back-up to keep in my truck. The clarity of the glass is very good considering the price compared to other brands. The warranty doesn't hurt either.

Compact, well built

Pros: I really like how these binos are a little bit smaller and lighter than other 10x42 binos. At the same time they're very sturdy and well toleranced. The rubberized covers for the lenses are among the best I've used and do a good job keeping the lenses clean. The eye cup adjustments are well indexed and satisfying. The picture is clear and bright. The neck strap and chest harness are comfortable. Cons: The plastic pieces on the neck strap webbing broke after about a year, meaning now I have the neck strap tied to the loops on the binos themselves. The depth of field of these is not as good as some other similarly priced binos I've used. I have to more finely tune the focus when using these for subjects 25-100ft away.

Great Binoculars

Shipped in a timely manner from Votrex. These are perfect binoculars for a sub-$500 set of eyes. I wish I could say I was surprised by their quality, but I expected this from Vortex. They have great glass and let in a lot of light. I highly recommend.

Good quality for the price

Clear glass perfect for hunting east of the Mississippi. Weight isn't too heavy. I don't love the bag/rig for it. It isn't bad just don't love it. But hey you don't buy them for the carrier

The Diamondback® HD 15x56s are powerful, clear, and sturdy. They're great for long-range glassing, especially with a tripod, and I think they're a great value for the performance.

Excellent optics at an excellent price

I'm an ornithologist. Sometimes I don't need my big expensive binoculars. These are great for walking trails in the neighborhood and also for birders who want a great value. The weight, clarity, and build of these optics are incredible. I've recommended them to many birders.

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 !!

Enhance your outdoor viewing experience with the 12x50 Diamondback HD Waterproof Roof Prism Binocular. Engineered to redefine the balance between price and performance, this binocular delivers an unparalleled optical experience that outshines its competitors.

The Diamondback HD is equipped with an HD Optical System, meticulously optimized with select glass elements. This advanced system delivers exceptional resolution, reduces chromatic aberration, and provides outstanding color fidelity. Experience edge-to-edge sharpness and superior light transmission, making every view a vivid spectacle.

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

The exterior lenses are protected by ArmorTek, an ultra-hard, scratch-resistant coating that guards against scratches, oil, and dirt. This ensures your binoculars maintain their high-quality performance, even in challenging environments.

Constructed with a rugged rubber armor, the Diamondback HD offers a secure, non-slip grip and durable external protection. Its waterproof construction, featuring O-ring seals, prevents moisture, dust, and debris from penetrating the binocular, ensuring reliable performance in all environments. The binocular is 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, making it a convenient companion for all your outdoor adventures.

The Diamondback HD also offers adjustable eyecups that 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 GlassPakTM 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, making your viewing experience even more enjoyable.

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.
