Diamondback HD 10x42

I have put these binoculars through the ringer for the last 3 years now and could not be more impressed. To start, I love that the focus knob is incredibly easy to use even in frigid temps and with gloves on. I recommend these for anyone looking for a quality pair of binoculars no matter experience level with binoculars. Vortex did great with these binoculars, the price, the warranty, and the customer service is all top notch.

Light weight

Worked great for elk and antelope hunting. I liked that it was lighter than my old ones and focused well.

Crisp and Clear!

I love binoculars, and have mainly used Bushnell Trophy Extreme 10x50 and 8x32, but decided to play around with Vortex as I've heard that they're good. Decided to bite the bullet when there are better discounts throughout the year. And babam, got them for $120. These bad boys make the image crisp and Clear, best bang for your buck! Powerful, better for the day via low light for the most part. Doesn't matter if there's inclement weather, cold, hot, wind, they will outperfuyoir expectations! Great for hunting, bird watching, etc.

Excellent

I've used these binoculars for several years for work and for play. They never have let me down with their clairty and rugged durability getting banged around in my work kit. They provide excellent detail when glassing for mule deer in heavy brush and with the 10x magnification provide a good enough view which is adequate for most hunters and mid range shooters. Only thing I would change on these is if they had a version that had range finding ability.

Excellent Budget Glass

I got these bino's for my kids and they love them. Compact and crystal clear! We were spotting deer well before shooting light with these Diamondback's!!! I wish they made the lens covers fixed so they wouldn't get lost (thanks kids) but other than that, great optics. These would be great for beginners or experts!

I have used these binos in the Wyoming back country for 3years now. From being tossed around in my truck to packing in many miles in a Elberlestock recon harness. They have never given me an issue. The glass is still crystal clear.

Best company in the industry

I had a failure on these glasses and vortex took care of me asap! If all companies stood behind their products and took care of their customers like vortex does the world would be a much better place. I dont why anyone would buy anything but vortex because of their warranty alone. But their quality is also where it needs to be as well.

Good quality

I use these pretty often at work. They're always super clear, very durable and you can feel they're good quality. They don't feel like a toy, or like they're gunna break. 10x isn't really much, but unless what you're looking at is more than a couple hundred yards they should work great.

Great binoculars for the price

Great binoculars for the price point. I haven't had a lot of experience in the field with them, but in my few test runs I am happy with the brightness and sharpness of the image. the included bag and harness are quality and convenient. the binoculars themselves feel sturdy without feeling too heavy. I got a chance to look at the supermoon and the glasses performed well, with a bright image and sharp contrast.

Very clear. Very durable.

I've had mine for almost 4 years now and have hunted with them every year. They're lightweight and small enough I can fit by range finder and binos in my chest pack together. I've never had a problem with them fogging up or getting scratched even through the rough stuff.
