EXACTLY what I needed! - 10/08/2015

by Dawn from Marietta, Ohio

I needed a binocular for my office windowsill—nothing fancy, nothing expensive—to show me the birds in the treetops 100 yards away. These bins will never be used outdoors, and only between 8 a.m. and 6 p.m. They will never experience rain or granola bar crumbs or high humidity. These Atlas Radians are EXACTLY what I was looking for. The clarity is perfectly good; they're not too heavy; they focus easily; and they were exceedingly affordable. Thanks for the good advice, Tom, Adrian, and Ben! I'm grateful that you didn't try to up-sell. I am a very happy customer!

Great binoculars - 06/03/2015

by Linda from Saint Paul, Minnesota

I love my new binoculars. I enjoy birding, and these are just right for me because they have all the features I wanted and they were very reasonably priced. Couldn't ask for more!

Great! - 06/02/2015

by Cynthia D. from Florida

Finally treated myself to new binoculars for casual bird watching, and I really like them! I needed close up focus as well as distance, and these do a good job. Easy to focus.. They are a comfortable size, not too heavy.

I am glad I bought these binoculars - 06/02/2015

by Sally from Rhode Island

I bought these binoculars for birding. I am very happy with them. The view is very clear. I decided to buy them after reading the reviews.

Great Bins for the price - 05/30/2015

by Melodie from Marion, IN

Great bins for the money. Use them for birdwatching. Would recommend them to anyone. Did great even on an overcast day. Color and sharpness were very good.

Great Product!! - 05/25/2015

by Erica from New York

The binoculars I purchased were incredible. They got me comfortably through 2 weeks of an intensive field ornithology course and were easy to use and navigate for a first time birder. The optical quality was great; I did have to wipe down the optics often but that could have been my preference for complete clarity (comes with a re-usable wipe). The focus knob was easy to use. Thank-you for a great product!

Quality at a great price - 04/28/2015

by Elton C. from United States

I purchased these as a birthday gift for our 12 year old grand daughter who is interested in birding. My wife and I have Eagle optics 10 x 42 rangers. I think these are very comparable for the price.

Super value for the money. You won't be disappointed. - 03/03/2015

by Rick from Temecula

Highly recommend! Excellent quality, especially for the price. The image is crisp and clean, no spurious glows around the object being viewed. (I noticed this in my old, hi-quality binos only after comparing with the Atlas Optics Radian.)Reasonable weight. Special features: Comes with cup covers for front and rear lenses, a carrying case... plus focuses in on objects as close as 6 feet. Super value for the money. You won't be disappointed.

8x42 Binocs - 02/18/2015

by David from St Louis MO

The 8x42 Binocular - it's a workhorse binoc for birding. We discovered them through our high school - standard issue for all ornithology classes. Rugged, easy to use, crystal clear viewing. Great, solid instrument. Understandable why the high school selected this manufacturer. We bought two, based on school's recommendation.

Very satisfied customer - 01/11/2015

by Kathy from Florida

I am so pleased with my Atlas Radian 8 X 42 binoculars! Everything about my experience with Eagle Optics has been exceptional. I was looking for a spare pair of binoculars in the $100 range. I am an intermediate birder on a budget. I also teach middle school students and take them on monthly birding walks and I wanted an extra pair that were student friendly. These binoculars have exceeded my expectations! The person I spoke to at Eagle prior to ordering was so helpful and recommended these Atlas binoculars . I love these bins! They are easy to focus , light weight and give me a great view. They are an excellent value for the price.

Project FeederWatch - 01/06/2015

by Elizabeth O. from Staten Island, NY

These binocs have enhanced my feeder watching. The up close focus is way better than my old ones.

Thanks - 12/27/2014

by Barbara C. from Montello

I purchased these binoculars for my husband on the advice of a friend, Daryl. My husband used them yesterday on a hike and was MOST pleased. He said he could even see the individual needles on branches. And, was able to spot birds much more quickly, without removing his eyeglasses. Daryl had said this was a big feature.

good binos - 12/20/2014

by orv from Va

Very sharp view, excellent value

Excellent value for beginning birders. - 12/10/2014

by Trinidad R. from Pittsburgh, PA

Since Eagle Optics was out of an Celestron 8x42 I originally wanted, they suggested these instead. I'm quite happy with them and couldn't tell the difference in quality between these and a Celestron 8X32. I got them for a great price, and I love them. Some off-lighting issues every once in a while (I don't know the technical term) that doesn't interfere with my birding. Easily adjustable for my eyeglasses. Not heavy and can hold them still without tiring (have gone on all-afternoon birding sessions). Smooth focusing mechanism for near or far sighting. Lens covers are attached to the binocs or through the strap. A nice protective case, too. A good investment for beginning birders and will still be useful when you're ready to upgrade. Great customer service by Eagle Optics, too. Glad I went for the x42 instead of the x32. Would I buy them at their full price of $300? Not on my budget. But with a good sale, I think beginning birders will find this to be a good investment. My plan is to save up for good camera equipment for birding.

Christmas present - 12/07/2014

by Brian J. from Kent, Ohio

good gift

Excellent - 12/02/2014

by JR from Texas

This is the best binocular that I have ever owned, anywhere close to the price that I purchased this pair for. These 8x42 Radian's are clear, easy to focus, built well & have the only snap on objective lens caps I have used....that really stays snapped on. I have owned & used binoculars that cost 2-3 times the price of this one, that are outshined by this 8x42 Radian. Very good value, & the best quality that most people will ever need. Liked my first one so much, I ordered another pair. For the price & quality, you can't beat it.

Very happy with our Radian binoculars - 11/26/2014

by Steve from Massachusetts

We are casual binocular users but after using several different inexpensive types over the years I decided to try to find a good quality pair for a reasonable price. I did all the research, learning about binocular characteristics on the Eagle website as well as 4-5 others, mostly related to birding as the 8x42 is very popular for that purpose. We've had these for a few weeks now and are very happy with them. The magnification and brightness are very good, allowing us to see deep into the trees behind our house to watch for wildlife. The field of view is just right for our needs.

We have a bird feeder 10-12 feet from the house so getting a nice, clear closeup of the songbirds has been a treat. We are not birding experts, but what we thought was a Fox Sparrow was really a White-throated Sparrow thanks to the clear close-up provided by the Radians. And we are very happy with the eye relief - we both wear glasses and we're able to have a full view at the same setting. There are no local stores to check out optics so we're glad we were able to find a nice pair online. The 30-day money back guarantee and lifetime warranty sealed the deal.

Atlas Optics 8x42 Binocular - 10/14/2014

by David B. from St Louis MO

IF.... you're looking for a good, solid quality binocular with a great price point, strongly consider the Atlas Optics Radian 8x42. Our high school has made these standard issue for the ornithology class. Reliable, excellent optics, very rugged. For these reasons, Eagle Optics is a great purchase!

Sturdy Optics - 08/29/2014

by David F from Washington

Pros: Sturdy, well constructed binoculars. All movement is smooth and controlled. Great clarity and easy focus, I'm using for bird watching and the definition is first rate.
Cons: I find they are a bit narrow for my big head so I have to have them positioned correctly to be able to see out of both eyes. I also haven't been able to use them with my glasses on effectively, not a major concern as the independent focus allows me to compensate.
Others: These are weighty, surprising so on first use.

Exactly What I Wanted from a Pair of Binoculars - 08/26/2014

by Austin from New York State

• Reasonably wide field of view
• Very clear and sharp. -- When looking at a distant ridge it was easier to distinguish deer with these, than with a similarly priced pair of 10 x 50 binoculars, from another manufacturer.
• Well-balanced weight -- They're light enough to be well suited to long hikes, but have enough substance that they are very steady in the hand
• Bright enough for almost any light conditions
• Good value for the price -- I paid $130 for these and think they're worth every penny -- You can pay more for higher quality optics, but as I am more of a nature/outdoors enthusiast than an intense birdwatcher, these are more than sufficient. Also, I don't feel obligated to baby these binoculars, as I might with a more expensive pair.
• Fantastic customer service and warranty -- I was recommended this pair by a representative of Eagle Optics, who was extremely patient, thorough and accurate, when answering the deluge of questions I had as a first-time optics buyer.
Neutral points
• You spin through most of the focus dial between two and 80 yards, which was a bit unsettling testing them in my backyard, But they still focus reasonably at much greater distances
• There is a tiny bit of blurriness at the very bottom of the field of view, but it's so small as to have no impact in real world situations.
• My gut reaction after using them in the field was that I wish the rain guard had a flip design similar to the objective lens covers, but I didn't realize you could tether it to the neck strap, so I'm going to try this on my next outing.

Great binoculars - 08/26/2014

by Mimi from West Coast

I watched a lot of reviews and information videos on binoculars, and then decided on these for our safari in Africa. I was very happy with them. They worked very well, and they were fairly compact for carrying around - an important consideration. Eagle Optics gave me great service and helped me choose. I felt very confident in using them for my purchase. I've had a few friend now who have bought the same binoculars and also been very happy with them.

Excellent - 06/27/2014

by Elle from United States

I had Eagle Optics Shrike previously, and brought the Radians after gifting my Shrike to my sister. The color of the Radian is definitely a bit more vivid than the Shrike. The barrel length is also shorter, so it is nice and compact, which makes up for the slightly heavier weight than my previous pair. I read a LOT of reviews online, and for a pair of binocs under $150, this is one of the biggest bangs for your bucks you can get.

Backyard Birder - 06/25/2014

by S Hinojosa from Texas

Prompt service, great quality and fast follow-up!

Great binocular for the price. - 06/11/2014

by Mark S. from Dubuque, IA

I stopped by the Middleton Wisc. showroom to purchase a set of binoculars for an upcoming trip. The salesman presented me with four models that matched my criteria. The Atlas Optic Radian 8x42 was my choice. The fit in my hands, the light transmission and color resolution really set these apart from the others. Plus the unconditional warranty was an added bonus. I am very pleased with the Atlas Optic Radians.

First Timer - 03/05/2014

by Vicki from Ohio

This was my first pair of "real" binoculars (I don't think my grandmother's mother of pearl opera glasses count!). I purchased them for an Amazon River adventure and they were great, easy to focus and great depth of vision. I was able to see the birds and animals that were pointed out and began to locate some of them on my own. I was surprised at how easy they were to use and how comfortable they felt when I wore them, good magnification at a reasonable weight and price.

Great but heavy - 03/04/2014

by Mdonohue from Oregon

These are great, easy to focus, but they are heavy.

Excellent quality and value - 02/25/2014

by Lisa from Boise Idaho

These binoculars were the first pair I have owned that were not compact. I was looking for a higher quality binoculars at a reasonable price and I have been extremely pleased . Some of the details such as ease of focusing and the sturdy carrying case and lense covers made all the difference. As a novice to bird watching these binoculars are perfect for hiking and scenic drives. Also very nice for my husband and me to each have our own set of binoculars instead of sharing. These binoculars are well worth the price.

No complaints - 02/08/2014

by Benjamin V. from United States

Well I needed a new pair of binoculars and did some serious comparison shopping between this and many other roof prism 8x42s of the same price range. These seemed to have all the lens coatings and other features of the Eagle Optics Denali and Vortex Crossfire at a lower price. They have fully lived up to my expectations, although they're not as bright or true in color as the Nikon Monarchs that I had before. However, this is acceptable for the price range. We'll see how they hold up in the long run!

My new binocs - 02/01/2014

by Donna r. from California

These binoculars are excellent..and for a great price!
Easy to focus and no problem with wearing my glasses.
The only minor flaw was that the logo / strength metal gizmo on the focusing barrel fell off...almost immediately.
