Rated 5 out of 5 by from I can see clearly! I bought these on clearance so for my cost they are phenominal. I consistently have friends amazed by the low light clarity when glassing coastal blacktails and elk . We compare binos side by side. Great eye relief too. The challenges to them? Very few! A bit heavy. The size inhibits smaller bino chest packs. I took them to eastern Oregon and was a bit chained on magnification for mule deer but I did expect that a bit. If you're hunting low light and poor conditions in timber and clear cuts these binos are the ticket.

Rated 5 out of 5 by from Great clarity, very ergonomic I have had these binoculars for just over a year now. They are great for the money! These binos did not break the bank and performed better than I expected them too. The clarity is awesome. The 8.5x shows very little wiggle while using them without a rest which is great when glassing off the road or while walking. I was also extremely impressed by the low light performance. The adjustable eye cups are another great feature. There's no struggling to find the "sweet" spot just set them up once, and you are ready to roll.

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 African guide approved These binoculars awesome. They are great in low light and have great clarity. I recently took them on a safari in Africa. Our guide kept borrowing my binoculars and telling me how nice they were. He thought they should of cost twice as much as what I paid for them. With all of the clients he gets over the years and all the different binoculars he has seen it speaks volumes to the quality of this product that he liked them so much.
