I have now purchased 3 Vortex Diamondback 8X42 binoculars. The first was for myself, based on a recommendation from a bird-watching friend. The second was for my older sister when she began getting interested in ospreys 2 years ago. The most recent was for my younger sister when we all went to Florida together. We are all now huge fans--my younger sister was transported with excitement at seeing black skimmers, roseate spoonbills, wood storks and scores of other striking species. I never go out without mine, and they have held up through wet, cold and challenging conditions. A wonderful product.
easy, simple, please
jay from florida
my new binoculars are great. reviewing, evaluating and making a decision was easy on the eagle optics website; plus their life-long warranty is an added benefit. so far, I am happy with my purchase, enjoying birding and these binoculars are living up to the claims. i am a happy camper here with my new binoculars.
Dave from Le Sueur MN
Just starting birding and these Binos were purchased to replace a pair of cheap Binos. What a difference, so much clearer and brighter. Great starting Binos for anyone.
Liked it so much bought a second pair for my wife
Donald H. from Kirkland WA
We received a recommendation from a friend to try a Vortex Diamondback 8x42 binocular as a great buy for the money. We bought one and have been very impressed from day one. We were so impressed that we purchased a second pair – also at Eagle Optics. We recently used them to watch Bald Eagles near Squamish BC in nasty weather. There were lots of magnificent eagles and lots of nasty cold rain! The binoculars performed perfectly. My wife and I both wear prescription eye glasses and the adjustable eye cups are a wonderful addition.
Sharon from Denver, CO
I'm very pleased with the binoculars. I use them for birdwatching and wildlife in our backyard and on the golf course. They work very well. I would recommend them for the casual bird watcher.
So nice, I bought it twice!
Gabi C from United States
Love these binoculars. The right blend of quality, weight, and price. Especially love the close focus range. Better than any other binoc in the price range. We used this model in my ornithology class in college. I bought one for myself years ago. I have had the opportunity take Vortex up on their amazing warranty policy. Turn around time is fast. I think I had the replacement/repaired binocs within a week of sending them in. This recent purchase was for my mother-in-law who is just getting into bird watching. Highly recommended.
Best view ever
Ernie from Alpena, MI
I purchased vortex diamondback 8x42,I am so pleased with them.I am thinking of buying a second pair for my grandchildren.
Love these binoculars!
D Moore from Nashville, TN
After considerable research, I decided on the Vortex Diamondback 8x42s and I have found them to be the exactly what I need for birdwatching and all-around viewing. Images are clear, focusing is quick, field of view is great. And, they fit my budget. Our backyard is a natural bird habitat and I reach for my binoculars several times a day -- from bluebirds in the birdbath 10 feet away to the red-tailed or sharp-shinned hawks soaring overhead, these binoculars are the ticket for me.
I think they are excellent value for the money. Incredible warranty. I have just ordered a second pair for my husband so we will not be fighting over these! I considered the 10x50s for the second pair but both of us like the 8x42s so much that we decided to go with what we know. Maybe another time . . .
Edward N. from Michigan
The Vortex Diamond 8 x 42 binoculars delivered everything I needed for bird watching. So far I used the bionoculars in my backyard which includes berry producing shrubs, a wildlife garden backed up by a 5 acre pond. This yards provides habitat for several species including the belted kingfisher, red wing blackbirds, sparrows, and the coopers hawk that ocasionaly perches on the bluebird house. The binoculars provided clear images with quick focusing, frequently at a close range.
Chris Ni. from Pittsford N.Y.
Having looked for quite a while at many different kinds of binoculars for birdwatching, I was shown a pair of Vortex Diamondback 8 X 42 by a fellow birder in the woods this Spring. These were so good that I went home & ordered a pair right away. The bright light gathering with these is extremely good. They are light enough to carry for long periods of time. The center focusing is smooth and easy to operate, & best of all the focus is clear & sharp from very distant objects, to objects a few feet away. I have a pair of 10 X 50's that are great for distance viewing, but cannot focus closer than quite a few yards away. These Diamondbacks are the perfect combination for birdwatching & all viewing in general. These are fully as good in every respect as other binoculars costing much more. I am extremely pleased with every thing about them & highly recommend them.
Tom H. from United States
Bought these for my wife for mothers day to watch her birds with. Quality is outstanding, very bright and sharp. They were on special so the price was great too. Would highly recommend!
Carl W. from All over - full-time RVer
Wow - I've borrowed and tested many types of binoculars and these are the best. Why? The field of view. That is what makes all the difference. Of course clarity, features (glasses on versus no glasses on), life-time guarantee, etc. are wonderful all for a great price. No hesitation, buy these!
J Sjoberg from Reno, NV
Wanted an upgrade from some old Tasco 10x50's and after trying my brothers Vortex 8x42's decided to get a pair. Very impressive for the price. I can't really see spending over $1000+ more for something my 70+ eyes probably couldn't see anyway...mayby a bit more for the HD version but not at this time. Close focus is a great feature. I'm tall and I don't have to get on my knees to see some of the small wildflowers that we have here in the desert. Delivery was very fast(2-3 days). The semi hard case is a bit bulky but could also hold a few other small items when packing for a trip. I'll probably try a harness carrier as they are a bit heavy with the neck strap...same goes with most of the others I checked.
I can see clearly now...
Doug J. from Hickory, NC
Thankfully, my backyard has become a bit of a sanctuary for birds of many varieties. I have put out feeders, houses, water sources, etc. over the past year or so and didn't realize how much fun watching these fury little jewels would become. Wanting to better see and understand them, I decided to seek out a good set of binoculars and spent many, many hours researching various websites, etc. After much reading of product reviews, birding advice sites, and blogs written by avid birders, I determined that 8x42 would be a good place to start. Since most of my use will be in my backyard, I also wanted a binocular with a very close focus as well as one that could reach further out for hiking and nature walks. I went to several local suppliers who have binoculars on open display to try out in the store and really liked the feel of the Vortex sets I handled. I stopped in at our local Wild Birds Unlimited and asked for the owner's advice on birding binoculars. "Here's what I use," he said, and produced a pair of Vortex 8x42 Diamondbacks from the back room. He then let me go out back and watch one of his bird houses with them. Experiencing the detail and clarity of these binoculars was simply amazing! A Mockingbird family was nesting in a house that was some 40 yards away and it seemed as if I could reach out and touch them. I asked what the owner thought of Eagle products in general and he advised it is the best selling line he carries and sited the VIP guarantee. He just happened to have a pair of the 8x42 Diamondbacks in stock and I bought them on the spot. I have to say that I am totally enamored with these binoculars. They are sturdy, feel great in hand, and work perfectly both with and without my glasses. The ability to focus on at less than 5 feet away is incredible and really allows you to see every tiny detail. The instructions are well written and help to get you started off with perfectly focused binoculars straight from the box. The right eye diopter was a bit difficult to turn at first, but I appreciate its tightness because it should prevent this feature from having to be reset frequently. The focus turns very smoothly and is positioned intuitively so that transitioning between distances is simple and effective without fumbling. All-in-all I can't imagine being more pleased with any of the other sets I researched and couldn't recommend them more highly!
Taylor M from Texas
Excellent buy, highly recommended
8x42 diamond back Binocular
Jack W. from Washington State
These are the second set I have purchased. Clarity of view is excellent, focus is fast, covers for lenses and carrying case are excellent.
Broke my first set. Returned for repair more than a year later. Was sent a new pair with the explaination that a repair satisfactory to mfg. could not be made.
Customer service is really great. Called, asked about warranty, told they warrant what they make. Asked for how long. The answer was "eternity".
Will now being looking to buy my next rifle scope here rather than Leupold.
Vortex Diamond 8x42
Rick F. from Racine, WI
A very nice binocular for the price. Has a very close near focus and a very wide field of view. Has a very nice feel and is rubber-coated. Images are very crisp. The eye cups screw out for eyeglass wearers. The only drawback was that the right eyepiece diopter did not easily move to adjust for the eye. In fact, I had to use a pliers to loosen it up.
Great glass for the money, quality control could be better
Fred from New Jersey
I am very pleased with the image from this pair of binoculars. And the service from Eagle is terrific. The only problem is quality control: the openings to attach a strap or harness are too narrow, limiting their utility. I have not seen any other binocular with this problem. Also, the objective lens cap does not fit, always falling off. But, Lindsay from Eagle sent me at no charge, rings, cable ties, and a better fitting objective lens cover. In the end, I am happy with this purchase. A very good image in a relatively compact size for a great price. If I were looking for an additional pair of binoculars now,I might look at another model, but I would definitely buy from Eagle.
Vortex Diamomdback binoculars
Doro from Tinley Pk IL
Received my Diamondback binoculars 8x42 from Eagle Optics I am very impressed with the binoculars. They are very well built and talk about the clarity I will be taking these with me to Montana this summer when we go fishing !!!!
Wow..I will enjoy these for some time
Dave from Erie,Pa
I am a hobbyist birder and figured I needed some nice optics to motivated myself to go birding more often. I was on a budget and after spending some time researching this vortex binocular fit the bill. The image and sharp and the colors are pretty much what you see, I haven't noticed warmer colors as of yet. Thanks Eagle Optics for a great product and fast shipping. Keep up the good work. Dave
best for what I could afford...
John from Southwestern Idaho
I have reached the point where I don't want to hunt anymore but still value spending time outdoors. My Leupold 8x30s were old and I could no longer adjust the diopter on the right eye for clarity. I have been going for walks with my pup and seeing wildlife and raptors and game birds and wanted a set of binoculars to view the wildlife. A friend suggested Vortex Optics (over his Monarch) and I went to a local dealer and fell in love the Diamondback series. They had both the 8x42 and 10x42. I spent last weekend checking out both magnifications and just could not decide. So yesterday, I took my friend's 10x42 Monarch on my walk and could not hold them steady - and after resting a bit, I still was not able to hold them still. As much as I value the extra magnification, it doesn't appear that I can benefit from it - unless I sit in my vehicle and don't move. So I bought the 8x42 set and went out this evening and watched some Barn Owls close to home - and started to really appreciate the wide field of view. Very nice for the bucks I spent - the colors are consistent between what I see with the naked eye and with the glass. The light gathering ability over the 8x30s was a marked change for the better and the clarity or sharpness of image was wonderful (real descriptive terminology!)- for my left eye. With my glasses on, the field of view appears narrower to me but the distortion was resolved. The feel of the binocular is appealing, especially the serrations in the rubber armor towards the objective lens. Now...are there things I don't like - not much. I like the Talon HD in 8x42 but was not enchanted with the price. And I wish I could use the 10 power for more resolution, but my age seems to preclude this. Regardless, I love these binoculars and recommend that you try them.
Vortex Diamondback 8X42
Gary from MN.
I purchased the Vortex 8X42 Diamondback bins for my wife to use as a grab and go bin for birding. The Vortex Diamondbacks are a very good value for the money. I compared these with Nikons, & several others in this price point, & concluded the Vortex exceeded in quality, the optics are very good, & the adjustable eye cups work great, with plenty of eye relief for eyeglasses. I would recommend these as a great value binocular, you won't be disappointed.
Hard to beat for the price
Lindell from Missouri
I ordered from Eagle optics and received my diamondback binos in 3 days. I was needing a pair of hunting binos that worked good in low light situations. I took them out, when I could barely see with the naked eye and low and behold I could see clearly through the diamondbacks. I am impressed. They are everything they say they are. The warranty with Vortex is also a selling point with me. Highly recommend these to the hunters out there.
Carolyn from New York
Everything fine except the larger lens covers are not securely attached. Any suggestions to avoid losing them?

Great Glasses for Deer Hunting
Mike from Reno, NV
Just got back from my deer hunt using my new Vortex Diamondback 8x42 Bino's. I purchased a four point harness, which is more comfortable than the traditional neck harness. They are the perfect size when hiking through rugged terrain, and the optics are simply incredible. I used them in both normal and low light and found them to be crisp and clear. I would highly recommend this product.
Johnny from South
I will be using them for hunting. Out of the box, they are crisp and clear. They are easy to focus. I wish the neck strap with easier to attach to the binos. It takes a little time which will be an issue when I change over to the bino system on my hunter safety system for hunting. Overall, I like them very much.
Happy with new binoculars
Bancroft from Chagrin Falls, OH
Thank you for the new binoculars. They were recommended by a friend and I am very happy with them.
Good all around binos
Sergio from Miami, Fl
I was in the market for a relatively inexpensive pair of binos that could do a little bit of everything. I am glad to say that these Vortex Diamondbacks fill the bill quite nicely. I used them at the zoo where they got me much closer to the animals. The views were crisp and clear and they were also really comfortable. I also got to use them during my recent vacations to Canyonlands National Park where I did a little bit of binocular astronomy. I would recommend these to someone like myself who is not a hard core birder and is looking for an all around good pair of binos for many applications. Can't wait to use them at Miami Dolphins games.
one wasn't enough
patricia from cooperstown, ny
This is, in fact, the second Vortex Diamondback I have bought from Eagle. The first pair were for me, and they were perfect. I never left home without them. Of course, when I took them to the shore to visit my sister and watch ospreys, I was the object of much envy. Everyone agreed they were dramatically better than any binoculars previously experienced, and so easy to use. So these were purchased as a 65th birthday present to my sister, who was overjoyed.
