High quality product operating exactly as described. Well built with clear optical performance. It is rugged, balanced, and feels good in the hand. Eye relief is a strong point and something to consider for a future buyer. Shipping was fast and on time. The lifetime warranty is to not be discounted. If anything is defective Vortex will stand behind their product. There is no embellishment from the marketing. The description is what you expect to receive.

For the price point, I don't think you can find a better set of binos. Perfect for east Texas hunting where you are glassing around 250-300 yards out.

Great binos for the price

These are a great set of binoculars. The lenses are clear and it feels sturdy. You won't be upset buying these. The glasspak is great for hunting and the neck lanyard is very comfortable. The only thing I can say is I wish they included the quick snaps to go between the glasspak and the neck harness.

I use these binos while hunting in the woods, or while at home looking at things off of my deck. They are lightweight and easy to use. They come with a nice case to store them in when they are not in use.

Nice Binoculars

I saw a buddy of mine using them over the weekend and decided I need them myself. They don't break the bank and they work as intended. Clear as day, and like the strap , carrying bag And accessories that come with it. A must on the range for anything up to 200

Great Binos

The Vortex Diamondback line is known for its mid-tier affordability. I would say this fits the bill. Binoculars are like scopes--you can spend a few hundred, or a few thousand--and you have to be realistic about your needs. I purchased these as a lightweight hiking option I could throw into my backpack, and also to use at the range when I didn't pack a magnified optic. It was especially useful for those days where I was using a red dot, shooting out at 100 yds or a little further, but wanted to see my impacts on paper without having to walk out there each time. I know there are much higher end binoculars out there, but I think many of the weekend-tactical community ends up buying something way more expensive than they will ever need for logo cred, and personally the Diamondback HD has done everything I've ever needed it to do. I would highly recommend.

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.
