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
