Diamondback® Classic 8.5x50 Roof Prism Binocular

Superior quality, high-performance hunting optics can find their way around your neck for a surprisingly affordable price. Boasting large, light-grasping objectives along with greater viewing power than delivered by 8x optics, the 8.5x50 Diamondback lets you close in on details missed by others at this time of day. Taking its lead from the Diamondback rattlesnake, this rugged binocular is striking in how well it detects life in low light. Huge field-of-view—the largest in its class— with enhanced fully multi-coated optics, phase-corrected prisms, waterproof and fogproof construction, soft tapered eyecups, rugged rubber armor. It's all there. Now you can use "wow!" and "thank you" in the same sentence.

Rated 5 out of 5 by from Great for Glasses Wearers Great product! I bought these because of the long eye relief since I wear glasses, and their overall performance is impressive. Bought another pair on clearance just in case. They are perfect for the deer stand at reasonable ranges. I just got back from a plains game hunt in South Africa, where these were subjected to a lot of dust and rough handling. I just rinsed them off, cleaned the lenses, and threw them back into the truck. A little bulky for stalking, but by that time, I trust the PH's eyes and glass.

Rated 3 out of 5 by from Oddball bino Overall the Diamondback binocular is a good binocular for the money when it is on sale or clearance. Otherwise overpriced. This model is heavy compared to other similar quality name brand binoculars. Adjustable eye pieces are made material (aluminum) that bends causing to stop utilization of adjustment. Plastic parts and rubber eye protecters poorly glued on. Optic clarity is decent. Overall good product, but another product not made in America. This pair will need to be returned for warranty work.

Rated 5 out of 5 by from This is the best pair of binoculars I've ever used I am extremely pleased with this product and I would buy another vortex product without hesitation they are the best optic company I have used so far in my hunting career. I have used this product for scouting only 2 times but I know without a doubt that these binos will last a lifetime. Even If they do break the vortex warranty is great. I definitely suggest saving your money for nice glass like vortex. I would say it is at least as good as Swarovski or zeiss and it's not even a 3rd of the price.

Rated 5 out of 5 by from Great tool for scouting Used this extensively on my last spot and stalk hunt for aoudad and mouflon in west Texas. The glass clarity and brightness helped me to pick out animals at distance without the use of a spotting scope(next on my list of optic purchases). They are not small, nor are they light but these were not issues for my particular hunt. The quality was showcased and confirmed by my hunting buddy in early/late low-light conditions. His pair of binos could not hold a candle to the Vortex Diamondback.

Rated 5 out of 5 by from Great Value Option I bought my Diamondback binos after hunting elk with cheap ones. The new Diamondbacks came with me on a DIY public land antelope hunt in Eastern Montana. We spent the day before the opener glassing multiple herds, including one that was using a hay field adjacent to a butte that would provide ideal stalking opportunity. We came back before sunrise on opening day. The Diamondbacks allowed me to confirm they were already in the hay field so we started our stalk before sunrise. During our stalk we noticed a half dozen trucks with hunters driving by - we were not the only ones that had found this honey hole, but we had beaten them to the spot. My friend and I both ended up with nice bucks - mine at an easy 100 yards and his at 350. We might not have succeeded without optics that could see in low light.

Rated 5 out of 5 by from My friends have bought many since using mine I bought this from Cabelas when I needed a new pair to replace some old ones. This is my first Vortex product and after one and a half seasons it won't be my last. For the price, the quality is amazing and they are extremely durable. That backed with the unmatched warranty it has since been the go to product for many of my friends. A great product to stock up on and have one in the house and vehicle.

Rated 4 out of 5 by from sub par eye pieces I have had to bring my bino in for repair. The rubber eye cups came loose from the metal under them. The customer service was awesome, but the repair only lasted a few weeks. These binoculars are very good for my type of whitetail hunting, I thought they were a little under powered for my antelope hunt. I would definitely buy another set even with the eye cup issue I am having.

Rated 5 out of 5 by from Couldn't believe the quality. After using a low budget pair for years, I decided to pull the trigger on a better pair of binoculars. I couldn't believe how clear they were. I've test drove a few really high dollar pairs at a sporting goods store, and two tell you the truth, these were comparable. I'm happy with my purchase. I can see me buying more Vortex products

Rated 5 out of 5 by from 100 Percent Amazed Bought these 85x50 Diamondback after Cabela's the sales staff recommended them. I have hunted with them in Alaska and am truly impressed with the clarity and light gathering capabilities. No problems with fogging. I thought you could only get this quality with the expensive brands. With vortex same quality at a fraction of the price.
