Is there a UV filter made for the Vortex Razor HD scope?

I want to order the  + couple other items including a UV filter for this scope. I cannot find any information on the thread size, are UV filters available? If so what size do I need, please?




Dear Stephen,
The  will typically not accept filters, nor is there a UV filter made for it. There are threads visible by the objective lens, but these are cosmetic--merely a design feature.

Pros and cons of buying a demo binocular

 I wanted to check with you about the offer you have online of a demo pair of this Zeiss model of binoculars for $849.  I’ve never bought demos before, so I’m not sure what the cons might be (how used?  any change in warranty? return policy?  difference in accessories they would come with, etc).  If there’s no real downside, I would get these demos from Eagle Optics.


Karen S.


Hi Karen,
Thanks for your inquiry.  The demo models we get come from Zeiss and are in excellent condition.  You can expect them to look like a brand new pair of binoculars would after they have been out of the box for a few hours.  The mechanics and optics should be perfect and the rubber armor may show minor signs of handling but no damage or defect.  

Demos aren’t previously owned pieces, but likely binoculars that have been displays at trade shows or something sent to a writer for a review.  With Zeiss, the demos will have the exact same warranty as a new piece and our 30 day return period will qualify on all purchases, including demo models.  

If I were in the market for a Conquest HD, I wouldn’t hesitate to save some money and purchase a demo model.
If you have any other questions or if I can be of further assistance, please let me know.

Best regards,

Need binocular for Alaska cruise

What size binoculars would you suggest for a cruise to Alaska?
So far I have been told 10 x 32 or 10 x 42.

And thank you for posting those videos!  



Hi Bruce,
Thanks for your inquiry, and for watching our Eagle Optics educational videos!  

An Alaska cruise sounds fabulous!  Personally, I would avoid a 10x because it’s not as easy to hold steady—especially combined with the added movement of being on a ship. My suggestion would be to get the best glass you can afford, and choose either an 8x32 or and 8x42.

The difference between the 8x42 and the 8x32 mm binoculars is mostly weight. The 8x32 mm will be lighter (average weight is 19 oz.) and smaller in the hand than the 8x42. The 8x32 won’t be quite as bright at dusk, but it will  have a wider field of view.

Let me know what you’re hoping to spend, and I’ll be happy to list of few favorites,. If you’d like to phone the store, we can talk about options. The number to call is 800-289-1132.

All the best,

Need help fiting Vortex DCA to my camera lens


I have a product question concerning the Vortex Razor Digital Camera Adapter (DCA).  

I have a lens with a 67 mm filter ring that I want to attach to the DCA.  If I remove the 58mm adapter ring, 72 mm is too big for the adapter and 67mm is too small.   

It appears that it will be an odd size, but I am hoping I can get a step up ring from 67mm to ?  Have you looked at this for anyone?

Best regards,



Hi Dean,
Thanks for your inquiry. 

You didn't specify the camera or lens you are using, but there is a possibility that the lens you’re using will not work for digiscoping. We recommend using a 50 mm fixed lens. However, you may be able to find a step ring that will accommodate your needs. We don’t sell one, but you can probably find one at a camera store.

Let me know if I can be of further assistance.

All the best,

How do I determine my IPD?

Hi Eagle Optics,
How do you measure IPD (interpupillary distance)? I sometimes have difficulty with various binoculars - narrow-set eyes and wear glasses. My current compact binos are a tad too wide.

Thank you,



Dear Lee,
Thanks for your inquiry. 
The best way to determine your IPD is to get your it from your eyeglass prescription, or by calling your eye doc for it.
Once you know it, we can help by making binocular recommendations. Simply give us a call.

Yours truly,

Need a lightweight compact for hiking the Appalachian Trail

I am a birder looking for a low-cost pair of small lightweight binoculars to take with me while hiking the Appalachian Trail. Can you give me some suggestions?

Also, I am traveling, so if I decide to order this, I will need to figure out where to have it shipped so I can pick it up en route. Can you tell me how many days to expect for an item to be shipped to Henderson, N.C., for instance.

Sounds like a great adventure! Here are some of my favorites under $250:

Our free shipping method is buy Fed Ex Ground. After it ships from here. it would be about 3 business days to North Carolina. There are options to upgrade to 2-day or overnight for an additional cost, if you prefer.

Best of luck on the trail!

What is the country of manufacture of the EO Ranger ED?

After doing a little research, it appears that your Eagle Optics brand of binoculars is manufactured by a company with facilities in both Japan and China.  Where are the new Eagle Optics Ranger ED 10x42 binoculars manufactured?

On a related note, I would really appreciate it if you would add the country of manufacture on all the products you sell.  For some people, that's a factor in what they buy.  Where the binoculars re manufactured wouldn't necessarily take them out of the running, but it is something I would consider along with all other qualities of the binoculars.

Take care,


Dear Brian,
Thanks so much for your e-mail.

The  is manufactured in China.

It's true that we don’t include the country of manufacture of binoculars on the website. That is because that information sometimes changes, and we’d rather give no information than inaccurate information.

If you have a question about the country of origin of a particular binocular or scope, we’d be happy to let you know if you call our store. The number to call is 800-289-1132.

Best spotting scope style for the seated user?

I plan on purchasing a scope for my wife who uses a power chair.  I've looked at your video on straight vs angled, but I wonder if you have any knowledge of preferences of seated users?
Thank you for your time.
Willard Z.


Dear Willard,
Thanks for your inquiry.

I think the choice of angled or straight would depend on where the tripod would be placed—next to, or possibly straddling her chair.

If the tripod can straddle her chair, a straight –bodied scope would be best, we think.  If the tripod is set up to the left of right of her chair, an angled scope would be easier to use, since the scope can rotate to either side. Most angled scopes have this capability.  If you’re not sure about a particular scope, we’ll be happy to check and confirm this for you.

All the best,

Eagle Optics
