Great Binocular! - 02/08/2012

by Cindy from Cary, NC

Great binoculars for bird watching. Good clear image and gathers light as well as the much more expensive binoculars. Love them!

Denali 8x42 - 01/31/2012

by John from Modesto, CA

I recently purchased the Denali binocular as a gift for a family member because I have the same binocular which I purchased a number of years ago, and I have been very satisfied with it, in fact, I often comment to my wife about how much I enjoy using my Denali binocular; I use mine daily!

Had to buy two - 01/30/2012

by Jim from Rio Grande Valley Texas

My lady friend bought a pair for herself and let me try them.I liked them so much I bought a pair for myself.Enough said.

good stuff - 12/30/2011

by mike from new hampshire

i have owned 2 different bino's made by Nikon in the same price range as the Eagle Denali's . i was always satisfied with the Nikon's and would continue to own them. the Eagle Denali's were a unexpected Christmas present that are every bit and maybe better than the Nikon's. the clarity is exceptional, the best.
i would recommend them to anyone looking to purchase good glasses.

Great Purchase! - 10/02/2011

by Sue from CA

Would highly recommend this product. Used them for game viewing in Namibia and they were easy to focus. The eye cups were easy and very quick to adjust for users with or without glasses. Several other people in the group tried them out and were impressed with the field of view and good sight picture. Close up was great for good bird viewing.

Our second pair - 09/23/2011

by Angela from Canada

Last year we bought a pair of these binoculars for our oldest son's tenth birthday. He is an avid birder and has really enjoyed his Denali's. (Mom and Dad have enjoyed them too whenever we get a chance to use them when they're not around his neck!) This year, our next son, who was turning nine, requested a pair of binoculars "exactly" like his big brothers for his birthday. And he got them. We are very happy with this product.

Review of Denali 8 x 42 Roof Prism Binocular - 08/05/2011

by Elizabeth from Lansing, MI 48915

I recently made an online purchase of the Denali 8 X 42 Roof Prism Binocular. This I did after reading the online detailed specifications and comparing with the next most expensive binocular (Eagle Optics Ranger 8 X 42 at $299.99 in the same general optical category -- for bird watching use). Overall, I think they are adequate but nowhere as good as the previous binocular I received from Eagle Optics some years ago. (Sorry, I cannot remember what they were other than they carried the brand name "Eagle Optics".)

The good features of the Denali are that they are lightweight, optics easy to adjust and nicely armored. The features which I find less than ideal are: the multiple anti-reflective coatings, the overall optical clarity and the strap (it's a bit too skinny). I wish I could have afforded a somewhat more expensive binocular as I think it's just a matter of using less than stellar components on the Denali. I thank you for the opportunity to provide this review. Thank you -- Elizabeth

Review with Grandson - 08/02/2011

by Larry from Garland, TX

We talked a buddy into loning me his Binoculars to review while my six year old grandson watched everything. I noticed things I like lens which enhance light transmittion due reflective coatings on glass.The roof prisms enhance resolutions.
They have a great shape to avoid hitting the string of a bow. The light mist of rain did not affect the non-slip grip. The eyes of a six year old are better than a 66 year old grandfather;thus the adjustment barrels keep game from observing movement

Nice Denali SuPRIZE - 07/16/2011

by DAVE ARBON from Ontario Canada

Well this is a first for me, I won these from Eagle Optics as a prize for reviews on previous purchases from them.I was able to compare these with a Atlas Radian bought a few months earlier , very similar in spec and performance.
This glass comfirms what a great step up Chinse binoculars have taken over the last few years.No longer do you have to spend a major amount of money to get a very good usable optical instrument,I can,t fault the Denali even if I had paid the full price for it.
In all honestly having too many binocuars in the house I had intended to sell it, however its going to be kept,simply because I like it,and also because of the fact that the good people at E.O. made a lousy week for me so much brighter.

Eagle Optics Denali - 06/22/2011

by Carole from LaPorte, TX

OMG! These binoculars are fantastic. I like to do some backyard bird watching and have always used department store binoculars. I recently went to a bird sanctuary and Eagle Optics was recommended by one of the visitors there. I had no idea what a treat I was in for when I ordered your binoculars. I can see my hummers so clearly and it is so easy to focus in or out. Highly recommend your product. There is no comparison to the department store binoculars.

Best we've ever had - 06/01/2011

by Robert from San Antonio TX 78210

A serious birder recommended Eagle Optics and a roof prism binocular that had a quotient of 5 or more when the first number is divided into the second, 42/8=5.2. We chose the Denali which was within our price range. With it we are able to spot birds in the bush and on the wing easily. It is the best binocular that we have ever owned.

Good Binos - 05/12/2011

by Danny from Boulder,CO

These Binoculars are great! Basic and simple to use with excellent clarity! I do recommend them! They also come with an excellent carrying pouch and sturdy lens covers!

Excellent optics and ergonomics - 03/27/2011

by Dan Wiley from Caliornia

I was interested in finding an alternative to my clunky 10X50s. Those are great for astronomy work, but literally a pain in the neck for extended walks during the day. I wanted something light and compact, but with good image quality.

After much online research, I decided that 8x42s would be the perfect size for bird watching, hiking, and other outdoor activities. I also wanted to find binoculars with a roof prism since they are more compact than the Porro prism type.

I discovered the Eagle Optics Denali 8x42s were quite affordable, lightweight (half a pound less than my 10x50s!) and received many glowing reviews.

When I received my Denali's, I was very pleased. Everything about them seems to be rugged and well made. The optical quality is superb: high-contrast images, sharp from edge to edge, and very little colored edges.

But along with the excellent image quality, it is the ergonomics which make these a real winner. At only 21.9 oz, they are very comfortable around the neck. The shape fits my hand perfectly with a nice cushy feel- not to big and not too small. The focus, eyepiece spacing, and diopter adjustments are very smooth with no backlash, and just stiff enough to stay put.

A huge plus for me is the diopter adjustment knob design. It is almost impossible to accidentally knock it out of adjustment, unlike my other binoculars. There is nothing worse than trying to quickly see something only to discover one eyepiece is completely out of whack.

The eye relief is excellent as well. I am a glasses wearer, and I find I can hold the eyecups a good half inch from my glasses and still focus fine.

I have discovered that I can easily operate these binoculars with just one hand. I am frequently holding my dog's leash with the other hand. If I spot something of interest, I can quickly and easily hold the binoculars up to my eyes and focus rapidly with the same hand, all with very little shaking. Nice!

Eagle Optics sells these with their unlimited, unconditional lifetime warranty. I don't recall seeing this kind of guarantee with other binoculars I evaluated.

All in all, I am very happy with this purchase. I carry them with me any time I'm outside enjoying nature.

Eagle Optics Denali 8x42 Roof prism binocs - 03/15/2011

by Lois from MT

GREAT binoculars at a very reasonable price. Great service from a great company. This is my second pair....we got tired of sharing!

Great all-around binocular for all levels - 02/15/2011

by Clay from Pennsylvania

About a year and a half ago, I ordered many of these for use by students in my department (Biology). I was initially attracted to them by the price, generalist magnification and objective. We use them in several courses including Field Ornithology, Vertebrate Zoology, and Wetlands Ecology. Hence, we have put them through the ringer and they have withstood some amazing punishment. Students love them; several have purchased the same model since using them in class. They come in a rugged yet soft case and are a great size for backpacks and in the hand. They are solid but not too heavy to carry for long periods of time. The relatively large central focus adjustment is easy to use with one hand and delivers a quick, sharp image. The diopter ring is nice and tight and not easily disturbed during general use. I am surprised by the quality of them given the very affordable price and the weather resistance. There is only one really negative thing about them and that is while the neck strap is comfortable, the straps tend to unravel. Hence, I would recommend, either burning or binding the cut ends of strap or the tying a securing half-hitch around the strap adjuster. All-in-all a great product.

Denali binoculars great for the budget - 02/03/2011

by Lesley R. from Jacksonville, FL

We purchased some Denali binoculars from Eagle Optics. The binoculars are used by people new to birding that don't have any or good optics. What a surprise for me. I currently use Nikon Monarchs, and these Denali binoculars are very good. I highly recommend these binoculars.

Very good quality for the price - 01/04/2011

by Carol C. from Lakeland, FL

I bought these as a Christmas gift and wanted a good quality binocular but didn't want to spend a fortune. I used my own Equinox binoculars which cost about twice as much as a guide because the gift recipient had used them and really liked them. When I received the Denali's I compared them to mine before wrapping them up. They were just as clear and even a little brighter and definitely have more contrast! The receiver of this gift is ecstatic and now I am thinking of buying another pair for myself and just use my Equinox bins as a backup. This Eagle Denali binocular is definitely a good product for the money and worth getting to keep or give!

Gift of binoculars. - 12/30/2010

by Nancy from Churchville, NY

The clarity of looking close up as well as far away is very sharp. Easy to handle and use. Thank you.

Excellent Binocular - 12/21/2010

by Tracy from Palm Coast, FL

I am new to bird watching and started with a cheap pair of Bushnell Falcons. I learned about eye relief for eye-glass wearers from our local Audubon Society and began looking online for the best options for the best price. I know I've found just what I was looking for. Today, I went out birding and my vision was never better. Wearing glasses does not hinder the experience at all, and I no longer have to remove them and see blurry birds! They are compact, comfortable to grip, easy to focus quickly, and lightweight, making bird watching a pleasure. The case is a nice canvas bag with a comfortable strap. Lens cups allow the option of hanging from the binocular, or removing them entirely while out in the field. I opted to purchase a harness rather than use the neck strap that comes with it although it also looks well-made and comfortable. Overall, I would purchase these again and would recommend these to any birder wanting binoculars that will provide excellent vision without paying the price.

Good buy - 12/12/2010

by Carol from Tillamook, Oregon

These binocs are a good buy. They are a good starter pair, or like me, if you need a spare while others are being repaired.They would be a good choice for children. I like the lens covers. It would be good if the right eye fine focus adjuster locked in place.

great buy - 11/09/2010

by L. M. from mesa, az

I have these binoculars, fit my hand well, light weight,and can see things well. Great price.

Best Bins for the price! - 11/08/2010

by Michael A. from Jamestown, ND

Got a pair for my wife, We really like them. Very clear, good colors, great in low light.
I will buy more when my kids are old enough.

We bought a gift for our daughter - 10/30/2010

by Gloria from Clinton WA

We already had a pair of binoculars from Eagle and really like them so we decided to buy a pair for our daughter who lives on a lake in California. There aare lots of beautiful birds in the water and around the lake. She really enjoys the clarity of the glasses. Thanks for a good product.

Satisfied with binocs, but case needs work - 10/28/2010

by Jim from Cedar Rapids, IA

The binoculars exceeded my expectations, but the case that comes with them is too small. Once I put the American Birding Harness strap on the binoculars... the strap + binoculars does not fit in the case.

Great Product - 10/27/2010

by Joan from West Bend, WI

I was very pleased with the reviews of the product regarding the binoculars. I wanted a comfortable strap, soft case, easy adjustments of lens and light binoculars that were easy and comfortable to use. Also easy to return if not satisfied and quick receipt after order placement. So far the company and product has met my expectations 100% and I am completely satisfied and have already recommended them to a couple of friends.

Happy with purchase - 10/21/2010

by Amy from New Orleans

I bought this binocular based on the good reviews I read. So far I am very happy with my purchase.

Great binocs for the price - 10/12/2010

by Sandy from Hilton Head Island, SC

I bought these binoculars because I needed a pair for a Master Naturalist class I was taking. They are light enough, easy to focus, and great for viewing birds, and nature. The price was attractive and I am very pleased with this purchase.

Very nice product! - 10/03/2010

by R Rogers from California

I am very happy with my Denali 8x42 binoculars. My first priority was binoculars that focus clear and easily with my glasses on, and these work great with glasses. I tried a couple of other brands with similar twist up and down eye pieces for use with or without glasses, but none of the others worked well for me. Next priority was binoculars that were light weight with a bright clear field of vision and a reasonable price tag. Again these binoculars do it. The construction seems very sturdy and the focus is easy to use and smooth. Even in low light situations these binoculars are bright and clear. In stores I tried a few pairs of very expensive binoculars and these stand up very nicely next to those. These are really nice quality binoculars and I would definitely recommend them to anyone.

Eagle Optics Denali 8x42 Roof Prism Binocular - 09/23/2010

by auntiestrophe from Marin, CA

I used these at dusk to watch Great Horned Owls in West Marin. Very happy overall with the sharp detail and lighting. Focus knob easy to manipulate. These were much better than a horrible pair called Parks Wave that I bought from a SF scope store as part of my newbie errors in this new hobby. Image was totally blurry with those. Also, I love the return policy. Overall, I would recommend these to other newbies who are looking in spend in the 150-175 range.
