Rated 5 out of 5 by from Eye opening The first time I used these binoculars it was as if the gods themselves bestowed vision to a blind man. Growing up in s family of hunters who viewed high end binoculars as whatever you grabbed off the shelf at Walmart I can truly say these changed my life. When I first used them it was like the first time I saw a HD TV. The picture is clear and crisp but the smoothness of the focus sets these binoculars apart from all the rest. The adjustment on the binoculars is so smooth you can easily see your objective and adjust without any movement. Once again these are the best I have ever used.

Rated 5 out of 5 by from Excellent quality and very clear optics. I purchased this product about a year ago to serve as my binoculars that I carry with me during archery tournaments. I wanted something was lightweight, small form factor, and had clear image. The 10x28 Vortex Diamondback met all the of these needs. I was surprised how bright the image was with the 28 mm lens even in low light. I am very impressed with the Vortex products I have used this far and I will definitely be turning to Vortex to serve my optics needs in the future.

Rated 4 out of 5 by from Good Binoculars for Specific Situations I was looking to purchase my first set of quality binoculars and went with the Diamondback 10x28. I took them out antelope hunting and enjoyed the clarity and quality. There were times I struggled to keep still enough to focus if I wasn't resting my arms on something. I think this had more to do with my eyesight than the product. I ended up trading them in and upgrading to the Diamondback 10x42, which have been excellent as well. I wouldn't hesitate to use these 10x28's for bowhunting or turkey hunting or when the ultra compact size is a benefit.

Rated 5 out of 5 by from Great for me Got em on a discount at the local B&M. I don’t know anything about anything. Dumb as I am, these are perfect. I don’t hunt hard. I don’t hunt heavy. I just needed something I could use in regular weather under regular circumstances and these are perfect for that. Only needed to see a couple hundred yards and they served that purpose well.

Rated 5 out of 5 by from Fantastic quality and price! I bought these binoculars 3 years ago and I’ve never regretted it. Wearing glasses makes it difficult to find a pair of Bono’s that allows me to see clearly and be comfortable to use. Vortex has made a great product with an amazing warranty that anyone should be ecstatic to own! They will have my business for all my optics needs!

Rated 4 out of 5 by from Archery Hunting I bought these specifically for archery hunting. They are nice, small, and lightweight. I hunt some brushy areas and sometimes it's critical to look at some sticks to see if there are antlers hiding in them. I've spotted multiple elk and deer with these binos and am not disappointed. Great for the price.

Rated 5 out of 5 by from Clean, clear and rugged. Perfect for my bow hunts Bought these for the Vip warranty and was blown away by the clear and sharpness of the view I got. Nice and light and easy to pack when chasing game through the brush. Opened my eyes to vortex. Will be making more purchases no doubt. Quality is back.

Rated 5 out of 5 by from Great buy I recently bought Vortex Diamoundback binoculars, and couldn't be happier. Excellent clarity and quality. I current own 2 other Vortex products the Diamoundback scope and Strikefire II red dot. Another great addition to my Vortex collection.
