Thank you, EO! - 04/12/2016

by Penny S. from INDIANA

I am 63 and a near-sighted contact wearer. I have used 10x50 binoculars for years because I really appreciate the larger image and amount of light admitted. I have no trouble locating a subject or holding the binoculars steady, supposedly a common issue with 10x50s. I was ready for an upgrade--no complaints with my cheapo 10x50 Nikons other than that the focus wheel would seize up in cold weather. Always had a problem using someone else's roof prisms, but Nina at EO talked me through the proper adjustments and even had me get my inter-pupillary distance from my optometrist to make sure the 'nocs I chose would work for me. Not many companies manufacture 10x50s, so my choices were somewhat limited--not necessarily a bad thing. I'd been considering Opticrons because I know their optics are great, but Nina convinced me to choose the Eagle Optics 10x50 Ranger EDs because of comparable optics and the life-time warranty. My new 'nocs arrived in a day, and I fell in love with them immediately. Super clear, sharp images, light-weight, easy to grip. The only shortcoming seems to be the EO strap. I had trouble with it gradually working free from the clasps, but I am working with different fastening techniques to see if that issue can be solved. A few months after purchase, I accidentally dropped my binoculars getting out of the car. The optics were fine, but one of the strap brackets broke off--very inconvenient. I called service, telling them what happened and that I needed my binoculars back for a birding trip in 3 weeks. I shipped them off to EO for repair on a Thursday and had them back in my hands two days later, thanks to Jody and her expert assistance. Free-of-charge, by the way. We've bought a scope and several pairs of binoculars from Eagle Optics over the years. Why go anywhere else?

Great Value - 12/22/2015

by Steve from New Mexico

Crisp bright image across entire field of view. Focus, eye cup adjusters and all controls work smoothly with just the right amount of firmness.

Case is too small

awesome - 12/03/2015

by Kathy B. from Wadsworth, OH

very happy with this purchase. I volunteer at the Cuyahoga Valley National Park in Ohio-- I wanted a good pair of binoculars for awhile now. Asked several of the park rangers and bird watchers and they all recommended that I check with Eagle Optics. The first day I brought them with me- our eagle decided to give a performance for us-- was awesome to be able to see him so close> As he landed on a branch- I was able to see his eye so clearly with these. they worked out great

Eagle Optics Review - 11/10/2015

by John S. from SE AZ

Customer service was excellent- shipment arrived promptly with no issues.
Binoculars have several issues- narrow field of view (compared to what we are used to), Multiple users had difficulty with focusing, eyepiece does not stay in place after quick hikes up hill or going through brush.Light gathering was not as good as expected, whomever had these was consistently last one to spot game on recent hunt. These were everyone's last choice to use with two different Vortex and a 30 year old pair of Nikon (all in same power range) being preferred.

Best I've ever owned - 11/02/2015

by Leon G. from Athens, GA

This binocular is the seventh middle-market binocular I've used over the last few decades. The others included three Nikons, a Swift, a Bushnell, and another Eagle Optic (12X50). The Eagle Optic Ranger ED 10X50 is superior to all the others by a wide margin. I just spent several days birding on the Outer Banks of North Carolina in strong sun. My other binoculars struggled under those conditions, causing me trouble with a variety of visual artifacts and color distortions. My new glasses handled those conditions without breaking a sweat. The image was sharp and distortion-free throughout and color rendition was accurate. Focusing is fast and smooth and the glasses fit comfortably in my hand. My only complaint, registered by other owners as well, is that once I put the strap on, the glasses would no longer fit in the case. That's a minor flaw, but one that Eagle Optics should have spared me.

EA Ranger ED 10X50 - 05/06/2015

by Richard H. from Winters, CA USA

I purchased this pair of bins to replace a pair of 10X50 that were stolen. The EDs are an improvement over my previous pair because I can see better at dawn and dusk and in low light levels of thick forest canopies. They are slightly heavier than 8X40 bins (which I also own) and because they have a slightly smaller field of view it takes a little getting used to but for raptor and water fowl watching the extra magnification is very useful. These are outstanding glasses and Eagle Optics is an excellent company to deal with. I highly recommend these binoculars, or any other Eagle Optics products for that matter.

Excellent Binculars, Outstanding Value - 03/06/2015

by Robert S. from Mukilteo, WA

I've been very pleased with the Eagle Optics new Ranger ED 10x50 binoculars which I've had for about one month. They offer remarkably sharp, bright images virtually edge-to-edge across their field of view. To my eyes there was essentially no noticeable chromatic aberration, or color fringing, even on pretty challenging views like back-lit mountains or the bright edge of the moon. The close focus distance is just over 8 feet which is quite remarkable for binoculars of this size. Construction quality seems very good. The eye cups adjust easily. The locking diopter works well. The lens covers and rain guards stay on securely. The neck strap is quite comfortable. The center focus works smoothly over a range of about one and a half turns providing an effective balance of rapid adjustment and fine focus capability. My only problem with the product as delivered was the case which I found to be simply too small. While the case was quite well constructed, the clasp had become deformed from being stretched in the box and I could not easily get the binoculars in or out of the case. When I called about the issue, the very helpful people at Eagle Optics customer support were able to provide me a somewhat larger case which is quite satisfactory. Many people will not keep these binoculars in their case at all as their well-fitting caps and weather proof construction make it easy to carry them on their neck strap or leave them easily available on a table or hanging on a wall near a window for quick access. I use 10x50 binoculars mainly for star gazing and more distant views and these binoculars are perfect for this. The Orion Nebula, the Andromeda Galaxy, and open clusters like the Pleiades, are spectacular at night, and I was lucky enough to be able to identify Humpback whales breaching at a distance of about two miles in the daylight. These are not small binoculars, weighing 1 lb 13 ozs with their strap, lens caps and rain guards which is the way most people will hold them. Putting them on a tripod, trading stability for portability, will make sense for some situations. Note that tripod adapters for porro-prism binoculars may be too wide for this roof-prism style with its smaller distance between the tubes. I think you'll find, however, that the Ranger ED 10x50's spectacular images, great low-light capability, and impressive close range focus will have you carrying them along on many outings. The excellent product offered at a very competitive price and the very knowledgeable and helpful people at Eagle Optics have made this purchase an outstanding experience which I am pleased to recommend highly.

quality binoculars - 02/09/2015

by Dennis A. from Wisconsin

I've owned a number of binoculars over the past 40 years, Nikon, Pentax,and Bushnell and I have no complaints about them I will continue to use a couple of them. All have been poro prism until I bought this pair of Eagle Optics Ranger ED's, they are roof prism .I don't know if that made the difference since it's my 1st pair or if the optics are so much better than my other binos but whatever the reason they are very clear. There is as much difference between them and my other binos as there is between my Zeiss scopes and my other scopes. Very good quality. And great warranty.

Quality Product - 01/27/2015

by John L. from Wimberley

I am enjoying using the Ranger ED 10x50 binocular. I especially like being able to adjust the Ocular Lens and then lock down the diopter so the setting doesn't change. Then it's simply a matter of focusing for the distance. The image is clear and sharp. I also appreciate the associated instructional videos Eagle Optics makes available.

The ED glass is worth it - 01/16/2015

by Steve P from United States

I've birded with a pair of Ranger 10x50's for many years but they've picked up some scratches and dings and I'd heard that the ED glass model is better in low light. The new 10x50 ED's came in yesterday. They definitely do better in low light, to me the extra cost is definitely justified by the improved performance. They are sharper than my old 10x50's as well but that may just be my rough treatment. Highly recommended.

Good product - 01/10/2015

by daryl b. from United States

Good clear optic for the money with good features. Bag sucks is to small.

Watching whales and fisherman - 01/09/2015

by Thomas R. from Ocean Park Washington

I bought the ED 10x50 as a Christmas present for my wife and I. We live on a bluff on the SW Coast of Washington and caught the end of the latest southward migration of gray whales. However the Dungeness Crabbers have been out the last few week nights and I could clearly see the boats about 1/2 to 1 mile on a moonlit night. I was surprised it could capture that much light, and the visual optics on this are somewhat better than a similarly priced Nikon that I have. I'm looking forward to doing some birding with them.

Fantastic Binoculars!! - 11/05/2014

by Matthew H. from Beaverton, OR

I purchased these for personal use after using them at work. I love the magnification and the light gathering capability. I was able to view Jupiter's moons on a clear morning. The locking diopter is a great feature, helping maintain clarity as the binocular is moved around, stored, and used again. I was nervous about the twist up eye cups but ended up loving them. I've told many of my friends about Eagle Optics and will continue to nudge them in that direction as they search for great quality optics.

Eagle Optics Ranger 10x50 ED - 10/13/2014

by John from New York

Excellent stargazing w/ Eagle's 10x50ED binocs

I had been a satisfied owner of Eagle Optics' 7x35mm and 8x42mm binocs. I used both for birding and the latter also for stargazing. I ordered a pair of the 10x50mm ED binocs for stargazing as soon as I saw they were available.

They arrived in a case that was a bit too small to stay closed: the clasp was so strained it deformed and let go. I called Eagle about it and they immediately sent me a larger case that fit and stayed closed.

I bench tested all three binocs to directly measure their effective aperture (see All measured as Eagle spec'd them. Many binocs do not.

With the 10x50ED under a dark night sky, star images snap into tight focus across the field. There is only the barest perceptible color coming in and out of focus on the edge of the moon. With the binocs braced on a monopod for image stability, I could just split Alberio (beta Cygni), a double star separated by 35", as two very tiny yellow and blue pin points. Contrast is excellent on the brighter galaxies and nebula. A very satisfying piece of optics.
