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 Awesome binoculars! I’ve had my eyes on these for about sixth month before I bought them, and I’m so happy I did! I was looking for a pair of vortex, because of the VIP warranty and the quality and versatility of vortex products. I used a pair of vortex cross fire binoculars as a sage grouse researcher for five months, and was impressed with how well they held up to the dirt, dust, weather and abuse I put them through. I wanted a pair of personal binoculars for birding, hunting and wildlife viewing. Friends and colleagues recommended the diamond backs. I love how durable the feel in my hand. I bought these pair right before a winter trip to Yellowstone and the worked awesome! Thy helped me see five members of one of the wolf packs in the park, as well as moose elk, and eagles. They didn’t fog up in the cold temperatures ranging from 8 to 20 degrees Fahrenheit. I can’t believe how clear the field of view is. I’m excited to continue to use these for years to come.

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!
