How do I get sand out of my binocular eyecups?

Have a question about cleaning them my new Eagle Optics Ranger ED binocular.  Yesterday I went on a bird survey on a long sandy beach which took over nine hours.  Part of the survey is examining dead birds which means sitting down on a log or the sand.  I am wearing them on a harness but still I managed to cover the end you look through (can't remember what you call each end) with sticky sand.
The eyecup was extended all the way out and there was sand stuck in the grooves. Took me a long time to clean it all out - well, I think it's all out now though I sometimes hear the cracking of sand as I move the eye relief around.  

I used the brush end of a lens pen, a microfiber cloth and blew on them.  Hesitated to use canned air in case I pushed the sand further in, also thought about dunking the ends in warm soapy water to try and float it off but I wanted to check with you to see what your recommendations are for cleaning sand off as I am sure this will happen again on a regular basis.

Any advice would be welcome.



Dear Carol,
Thanks for writing! You’re talking about the ocular lenses. I would use the canned air. Not water.  Also, you might want to keep the ocular lenses covered with the  as often as possible when on the beach. Keep them tethered to your neck strap, and get in the habit of putting it over the lenses whenever you’re not viewing through the binocular.

Sand is a bugger on binocular lenses and under eyecups.  If you can’t get it out satisfactorily this time, you’ll have to send them here for cleaning—with the Eagle Optics warranty, there is no charge for this service. Be warned though, it would mean you’ll be without your binocular for 2-3 weeks. Maybe once you’ve had to endure being without your binocular that long, you’ll opt to use the rainguard more diligently.

All the best,

Need binocular with good close focus and narrow IPD

Hi folks, 
I am looking for a new pair of binocs for birding and close-focusing on insects.  My husband's (Eagle Optics Ranger) focus to 3 feet, so I'd like something similar: waterproof, lightweight, etc.  My problem is that my eyes are close together.  I don't see any information in the specs on your web page about the interpupillary distance.  What is it for the Vortex Viper HD  8 X 32?

My Nikon, not roof prism, is about 55mm for that interpup. distance.

Thanks a lot,

Kitti R.


Thanks for your inquiry.  The IPD on the 8x32 Viper HD is 58mm.  Depending on what exactly you need, this may be a bit too big. It’s hard to find a roof-prism model with a narrower IPD.  The offerings are limited but I have a few suggestions that may work:

8x32 Zeiss Conquest HD: 53mm IPD and close focus of 4.2 feet.

Atlas Intrepid ED 7x36: 54mm IPD and close focus of 5’

Opticron Verano 8x32: 55mm IPD and close focus of 4.9’

The Verano is very similar to the Viper HD while the Zeiss Conquest is certainly a bit of an upgrade.  The Intrepid is a less expensive alternative with a narrower IPD.

If you have any other questions or if I can help you further, please let me know.

Best regards,

Will an Opticron eyepiece fit my Kowa scope?

Dear Informed Staff,
I currently have a Kowa TS612 scope with a 27x wide lens. Since this is a fine lightweight scope I would like to take it into the field more often. I would like to add a zoom lens. Many birding forums have suggested the Opticron HDF 20-60x zoom. It appears that it screws into the lens cover on the 612. Do you know if the Opticron that you are selling does this?

Also, can you suggest a lightweight tripod for the scope? The tripod would need to fold down to 26" in order to fit into my suitcase, but extend to at least 60" for scoping since the 612 is a straight angle scope and I am 5' 11".Your advice will be appreciated.

Ron Becker


Hi Ron,
Thanks for your inquiry.  I don't have a Kowa 612 available to test the fit of the Opticron zoom eyepiece, so I'm sorry to say I can't confirm this for you.  Your email is the first I've heard about this possible adaptability.  It's unusual but not unheard of for scope bodies and eyepieces from two different manufacturers to be compatible. 
Regarding a tripod, I would recommend the Manfrotto 190 Go tripod legs:
The recommended tripod head for this would be the Manfrotto 128RC:

If there is anything else we can help you with, just let me know.

Best regards,

What eyepiece comes with a Kowa TSN 82SV?

Hi EO Team,
I am planning to order the Kowa TSN 82SV 82mm Angled Spotting Scope.   Does the 25x extended eye relief come with this scope?  If not how would I get one? 



Dear Jerry,
Thanks for your inquiry. With Kowa, the scope body and eyepiece are sold separately. However, the Kowa 60/66/82SVmm Scope 25x Long Eye Relief Eyepiece can be ordered and will fit the Kowa TSN 82SV 82mm Angled Spotting Scope.

If I may be of further assistance, please let me know.

All the best,

Need a small binocular with good close focus

I'll be going on a nature-related trip soon and need a lightweight binocular for viewing birds and wildlife, and with a good close focus for insect and butterfly watching. What can you suggest?




Dear Nan,
Thanks for your inquiry.

In regard to a small binocular with a good close focus, you could consider, in order of optical quality:

Pentax Papilio II 6.5x21 Binocular This binocular is known for having the best close focus of 18".

Kowa BD 8x25 Binocular (Green) (6 ft. close focus) A very nice compact binocular. Good value. 

Eagle Optics Ranger ED 8x32 Binocular  (4 ft. close focus) Sharp and bright, with ED glass, and better light gathering with the 32 mm objective lens. No fault warranty, too.

If you have any questions, don't hesitate to call.

All the best,

Eagle Optics

What current model compares the the discontinued Vortex Fury?

Question: My wife has a pair of Vortex Fury 8X42. I really like them and was going to buy the same but note that they are discontinued. What is the equivalent? I like the 5 foot close focus possibility.Also, I prefer eyecups that twist up and down like the Fury's did.




Dear Gary,
Thanks so much for your inquiry. It’s true that the Fury is discontinued, and has been for a few years. I’d say the current equivalent would be between these two models:

Vortex Diamondback 8x42 Binocular ($219.99) Close focus 4.5’

Eagle Optics Ranger ED 8x42 Binocular ($329.99) close focus 5.2’

The image through the Ranger will be noticeably brighter and sharper than the Diamondback, but physically, the Diamondback looks more like the Fury did, and is a couple ounces heavier than the Ranger.  I suppose the decision will rest with your budget, though. Both have no-fault warranties, and both have twist-up eyecups.

If you click on the “media” tab on the product page, we have a 1-minute video showing the features of each of the binoculars, including the eyecup mechanism. Click on the above links to view each of the binoculars and their videos.

If I may be of further assistance, please let me know.

Yours truly,

Want to use the Sony Alpha 6000 for digiscoping


I have a Swarovski 65mm ATS spotting scope. I am wanting to use the Swarovski TLS - APO Digital Camera Adapter for ATM/ATS/STM/STS for pictures. Do you know if it is compatible with a Sony Alpha 6000 mirrorless camera?

Jeff M.


Hi Jeff,
Thanks for your inquiry. Swarovski TLS - APO Digital Camera Adapter for ATM/ATS/STM/STS works well with most small-bodied point-and-shoot cameras with a low optical zoom (4x or less). So I would think it’d work with the Sony Alpha 6000. Mirrorless cameras often work with either of the two Swarovski adapters.  With the Swarovski TLS - APO Digital Camera Adapter for ATM/ATS/STM/STS , you would also need the Swarovski T2 Adapter Ring (Sony) plus an E mount T ring which we don’t carry, but you could find online or at a camera store.

Our 30-day return policy enables you a generous amount of time to try either of the adapters.

If you have any questions, don’t hesitate to ask.

All the best,

Can the Vanguard Endeavor binocular be mounted to a tripod?

Does the  have a tripod mount?

Thank you,


Dear George,
Yes, the Endeavor has a 1/4"x 20 threaded hole in the front of the hinge.  To mount the binocular to a tripod, you would need the Vortex Binocular Tripod Adapter or similar adapter.

All the best,

Needing upgrade advice

I am looking for a good piece of glass  for birding, preferably 10x42.  I have been in the field as an observer for ten years and have used both Nikon and Vortex.  

I think keeping it under $500 is a good idea, as we don’t tend to make too much money in the environmental education field, but I would be willing to spend more if it’s a deal I just can’t say no to.
I would be very happy with the EO Ranger ED, but I have been in the game so long that I would appreciate a significant upgrade from my Monarchs.  So, I am willing to spend money on a solid piece of glass, but I don’t have much.

Anything EO is willing to do is very appreciated.

Enjoy the long summer days,

Joshua T.


Hi Joshua,

The challenge is finding a binocular that represents a “significant upgrade” from the Nikon Monarch around $500.00. Do you know which generation of Nikon Monarch? Which Vortex binocular have you used? 

Truth be told, some of our staff see little difference between the New Ranger ED 10x42 ($339.99) compared with the Vortex Viper HD 10x42 ($599.99). Depending on the Nikon Monarch model you have, I’m not sure either of these binoculars would represent a “significant upgrade.” 

On the other hand, something like the MeoptaMeoPro HD 10x42 ($899.99) would, in my mind, represent such an upgrade. But then the question becomes are you willing to pay that much for what I define as the upgrade I think you’re looking for? Another $200 or $300 doesn’t really buy the end-user much in terms of optical performance, but this is a somewhat subjective position based on my experience in looking at optics every day. 

I might ask how much of a “wow” factor are you looking for, but that’s also difficult to ascertain via words. Having said all of that, the New Ranger ED is an excellent choice.

Digiscoping adapter questions for my Vortex Razor scope

I purchased the Vortex Razor HD 16-48x65 Angled Spotting Scope last year. I am interested in purchasing an attachment for my  to allow me to digiscope with it. 

On your web site it appeared that you had an adapter that was suitable for this camera.  I wanted to check with you before I ordered the adapter. 

Also, I have also read  that there is a digiscoping adapter for iPhones.  I have iPhone 6 -- do you sell these adapters?  Do you know that they can provide good pictures?




Dear Jeri,
Thanks so much for your inquiry.

For digiscoping, a point-and-shoot camera needs to have an optical zoom of 4x or less. While I'm not familiar with your Canon Powershot, I looked its specs up online, and it has an optical zoom of 30x. While it might be a fine camera, it will not work for digiscoping, unfortunately.

The iPhone 6 will take amazing photos! It is great for digiscoping. You have two choices for iPhone 6 adapters that I am aware of. First is the Kowa TSN IP6 iPhone 6 Digiscoping Bracket which will fit your Razor.  The second is to go to Phoneskope also makes an iPhone 6 adapter that will fit the Razor scope.

If you have any other questions, please don't hesitate to ask.

All the best,

Eagle Optics
