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.

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.

Great quality, great value - 01/23/2014

by Kyle from NH

I have had the Atlas Radian 8x42 Binoculars for about a year and a half, and I must say they have proven to be a great quality at a great value. They provide awesome clarity and field of view. They have withstood many, many birding outings in weather conditions ranging from gale force storm winds to -20 degree cold. They are a reasonable weight, and a very comfortable grip.

Can't beat that lifetime warranty, either!

I would certainly recommend for the casual and extremely active birder.

What a deal - 01/21/2014

by Peter A. from Orem, Utah

These are a very impressive binocular. I would suggest them to anyone as a birder,hunter or even to watch sporting events like football.

Great bargain - 01/13/2014

by Steve V. from United States

I bought these for my father as a Christmas present. I helped to get the strap on and had a chance to look through them and was impressed with the quality. They felt solid and were easy to hold up.

Couldn't be happier! - 01/11/2014

by Robert C. from Tempe AZ

These Atlas bins were on sale for $99.00 and I bought a pair for a young, new birder. I can't believe the quality for this price. I have Zeiss and Brunton glass just for comparison. And Eagle Optics went way beyond extra in the service department by covering the extra shipping costs for weekend delivery.

Eagle is awesome. I've purchased a lot of products from them and it's always the same solid value and service.

fabulous! - 01/10/2014

by Emily F. from philomath, oregon

Very satisfied with product. the atlas optics radian 8x42 binoculars were a gift to my mom. They exceeded her expectations. Easy to use. Excellent depth of field.

A Very Happy Camper - 01/10/2014

by B Ford from San Antonio Tx

I am a beginner bird watcher and my budget was $100 or less.
Did considerable online research. Final decision came down to the Atlas and a popular well know brand.
The main reasons I chose the Atlas Optics Radian:
. price was $99 and free shipping;
. Eagle Optics Platinum Protection unlimited, unconditional
lifetime warranty;
. fully multi-coated lenses, eye relief 17.5mm, close focus;
. it included the accessories & case.

The Radian serves my needs perfectly. Works very well with glasses, easy to focus, light weight, excellent clarity, wide field of view.

Would definitely recommend and purchase again

Atlas 8x43 Binocular - 01/08/2014

by Roger V. from The Villages, Fl

I'm very pleased with the quality and price of the binoculars.
These are my first binoculars for bird watching and they fill all of my expectations. I would recommend these to a friend.

Good binocs - 01/07/2014

by Tonya G. from Mason City

I was looking for something nicer for the kids since they are progressing with birding as a hobby. These are durable and easy to use. Kids are 11,9,7.

Impressive binoculars - 01/05/2014

by V P from USA

The field of view and amount of light is exceptional. Clarity is great as well. The eye-pieces have two discrete lockable positions, which is clever. The compact size enabled by the roof prism makes using this pair of binoculars very convenient. The build quality is solid and the binoculars are an exceptional value considering the price ($100 at time of purchase).

I used the binoculars for birding. My professional birding guide was so impressed that he wanted to buy mine on the spot because good binoculars came at a premium in the country we were visiting. I sold it to him for the same price as I bought it for but I wish I hadn't as the price has gone up. I would buy another pair again.

Novice Sees Light - 01/03/2014

by roger h. from western mass

Eagle Optics(the company) was suggested by an experienced birder whom i had asked for binocular advice. When i called their toll-free number, a person answered on the first half-ring. No Prompts. And the two or three women and men i spoke with on different days were professionally engaged: i.e. knowledgeable, experienced, helpful. I purchased a sale item- Atlas bins-from an Eagle Optics email. Uncharacteristically, i did no research prior to ordering. They arrived quickly (either the next day or day after and no shipping/handling fees) and have exceeded my expectations as eye-openers and even more impressively as light enhancers. Atlas Binoculars 8x42. I now know the company(Eagle Optics) is in Wisconsin, manufactures and services Eagle Optics Brand, but also offers other quality lines. What made me an instant appreciator of Eagle is their respect for your time and your role in the dynamic of exchange. Product exceeded expectations and personal contact points were supportive. They're there on site. They understand and speak english and don't waste your time 'over-thanking' you for submitting to security questions etc.
My only disappointment comes as a result of trying to submit this review. I am always sorry to see the unneeded 'stasi' like 'captcha' security (i'm always rejected at least once) as i have been today. Still, it's an unqualified 5 Stars for Eagle optics because i trust if i wrote to them about the annoying captcha they would either explain why they use it or recognize it's wrongness.
MBA alert: this is a company getting it right in the 21st century.

Great value for gift; Would have kept them. - 01/02/2014

by Roz K. from San Francisco

These are a great value, not too heavy, perfect for a birder who likes to do a lot of hiking, and doesn't want to carry too much weight. If they weren't a gift for someone who was living with "monoculars" having broken his, I would have been happy to keep them.

Atlas Radian 8x42 - 01/02/2014

by LARRY from Tennessee

Got these fine binos at an EXCELLENT sale price for my grandson's first pair of "real" binos. I was impressed with the quality and clarity. I own the Eagle Ranger 8x42 the Atlas comes close to them in every way.... Just not quite an EAGLE!
Great starter pair for a kid!

The Amazon River Never Looked so Beautiful - 12/27/2013

by Jerry S. from Boston, MA

My wife and I just took my new Atlas Radian 8x42 binoculars along for a week long excursion on the Amazon River, travelling with a guide and 15 fellow adventurers, departing from Iquitos, Peru. I was impressed with the quality, style and optics of the new binoculars, which allowed me to quickly and clearly capture the images of many (often fast-moving) birds, monkeys, and river dolphins, and butterflies. My fellow travelers shared my amazement that a pair of binoculars could produce such a clear image at such a fantastic price. The fact that they were waterproof was a must in the humidity and rain of the Amazon basin, and the attached lens caps were a real plus. Even my guide was impressed, and asked me for the Eagle Optics website so he could recommend these fantastic binoculars to future clients. My wife wants her own pair! We'll never travel without them.

Incredible Value - 12/06/2013

by John K. from Hayward, Wi.

I recently bought two pairs of these binoculars based on the reviews for two of my grandsons for Christmas. The will be used for bird watching, Deer hunting and viewing sporting events. I personally have Eagle Optics ranger binoculars in 10 x 42 which I could not recommend more and use daily and also Pentax 8 x 42 DCF WP my old standby which I also feel are very sharp. I opened a pair up and checked them out at close and long range. I was astounded at the clarity as well as the sharpness. These binoculars are a incredible value and definitely worthy of your consideration!

Good binoculars for birding - 11/23/2013

by Bill K. from Daytona Beach

My problem is that I am nearsighted with stigmatisms. These binoculars a have a wide bright field that make it easier to spot birds and focus in on them.

atlas optics radian 8x42 binoculars - 05/01/2013

by gary o. from lutz,fla

I had met a couple at the beach who were bird watching.Talking to them they showed me the pair of binoculars purchased from eagle optics. They impressed me so much I came home and looked up the sight and ordered a pair of my own.The clarity is excellent and the warranty can't be any better.

I am very happy with my purchase. Great quality and the price was right. I am an occasional birder so I did not wish to spend too much money.

Great Buy - 04/04/2013

by Mitchell S. from Monroe, WA

Bought these for casual bird watching. They have exceeded our expectations in clarity, focus, and ease of use. Great value.
Don't see anyone being disappointed.
