Rated 5 out of 5 by from A Snipers Perspective Needed A pair of Bino’s For an upcoming elk trip. Winters in the Wyoming mountains are not for the faint of heart so I know they needed to be durable and reliable among all other things. After testing many many options at the local hunting outfitter I decided on the Diamondback. The clarity was amazing. I was able to glass the snowy peaks for an hour before I needed to give my eyes a break. My uncle (lifelong hunter) asked to use them for a second and immediately said “wow”. He asked me if they were of another brand. (Rymes with Shmarshmoski). I laughed. Goes to show how much tender loving awesomeness goes into these things. Would recommend to a friend 10/10.

Rated 5 out of 5 by from Best Buy for the Budget Hunter. I got these binoculars after searching for months for the best product for my budget. I do some wildlife observations for work as well as a lot of glassing for hunting. The 8x42 are the perfect size and weight, you can wear them all day. The rubberized finish is perfect for holding in cold or wet weather, and it seems to stick to my gloves like glue! I've never had the lens fog up, even when going from my warm vehicle to a cold tree stand. A good few months of not eating out or buying coffee and you can afford these. If not the Crossfires are a good second choice. Best buy for the budget hunter.

Rated 5 out of 5 by from You get more then what you pay for! I picked up a pair of the 8x42’s for work an they are fantastic! I beat the heck out of these things. They are always tossed up in the dashboard of the truck, an often fall to the floor boards when in bad terrain. Been using them for over a year and they still hold up! The glass is often covered in dust, but a quick rub down from a glass cleaning wipe clears them right back up. Had the “vortex 8x42” sticker fall off from the focus knob and had the screws start to come loose, but tightened them back down an she runs good as new! Great bino’s for the price. Decent glass, and extreme durability!

Rated 5 out of 5 by from Great Product I am admittedly a research geek and thoroughly review a product before buying. I listened to several hunting podcasts where regular people were asked to talk about their level of satisfaction with a product and everyone was extremely pleased with their Vortex products. I went to Cabela's and looked at several brands and their features, and walked out with Vortex. As a midwestern deer hunter, I need something that is clear, crisp, won't fog and lets in a lot of light at dawn and dusk. The multi coated optics on the Vortex Diamondback are more than adequate for the hill country of SW Wisconsin. I could've opted for higher end models but the difference was negligible and Vortex's warranty beats them all!

Rated 4 out of 5 by from Better I've had my Diamondback 8x42s for 5+ years. They are as clear today as they were when I bought them. I have a competing brand (they also make cameras) in 10x42 and still prefer to use my Diamondbacks. I can see better at 8x than I can with 10x with theirs. Things I like about my Diamondbacks - durable - smooth adjustments - clear as day - quiet coating - light transmission is spectacular and works great with Vortex tripod accessory. I have a Vortex bino-keeper as well that I love. I can harness the binos close to my body. When I raise them to my face I don't have to worry they fold up skewing my view because the bino-keeper holds them in place. Great product that gives me confidence in the field and incredible warranty. Thanks Vortex.

Rated 5 out of 5 by from Bino newbie totally satisfied! Up until recently, I hadn't found the need for Bino's or more so didn't think I did. After starting more 3D archery shoots I quickly realized they were needed. Everywhere I looked Vortex name kept coming up in every positive review I read (and I am a Review-Monger!) and made the move to buy the Diamondback 8x42 binos, being bowhunting and archery shoots are my passion. I have to say I am very impressed with the clarity of the glass and the weight of these. I know that these binoculars combined with the Vortex Glasspak I got will surpass my expectations for my bowhunts and 3D shoots for many years to come! The piece of mind of the VIP Warranty is the greatest feeling to have, knowing that if something happens with them, Vortex has my back.

Rated 5 out of 5 by from Amazing clarity I bought these in the middle of this season and have been blown away. The clarity is amazing. The structure is solid. I've seen Steve Rinella use Vortex optics on Meat Eater and tout the value in not going cheap on optics. He was absolutely correct. These are great in low light, facing towards the sun, and in normal conditions. The warranty offered by Vortex is also unparalleled. Holding these also makes you understand how they can offer that warranty. These things are solid! Great product overall. Highly recommended!

Rated 5 out of 5 by from My first These are the binoculars that turned me on to the Vortex family! I was being cheap and ended up buying the 8 powers but I couldn't have been more happy with them. I bought the very first pair and they lasted for a while until the eye pieces stopped working and imperfection in the glass showed up. I sent them in for repair but Vortex ended up sending me a brand new pair! They are a great binocular and they will continue to get my business.

IS THE NEW DIAMONDBACK 10 X 50 SUITABLE FOR BIRDWATCHING?  HOW CAN I TELL THE DIFFERENCE WHEN ORDERING I.E IS THERE A DIFFERENT I.D. NUMBER.   IS THERE A NEW VERSION OF THE 10 X 42 ? THANKS

Asked by: Acid
Yes, the 10x50 would be great for birdwatching! The newest Diamondback 10x50's SKU is DB-206, so you will want to look for that model.

I received my Vortex Diamondback 8 x 42 binoculars as a gift last summer. I really enjoy them! A month ago I lost both the raingard eyepiece covers and the tethered outer lens covers while hiking in Mexico. How can I replace these?

What is the difference between Diamondback 8x42 vs Diamondback 8x42 gen2? How new is the gen2 version?

Asked by: Chris
The current version of the Diamondback are optically very similar to the previous version, the main differences are in the cosmetics of the binoculars as we gave them a new look.

What is the light transmission on these?

Asked by: Nicholas
We do not measure light transmission percentage because there is not an industry standard for measuring it.

The binocular articulation joint was very tight, (hard to move) when we purchased them and we thought the joint would loosen with time and use however 1-year later it is still tight, how do we get it to free up a bit?

Asked by: Terry
Give us a call at 800-426-0048 ext 6, we can get you set up to send them in.
