Hoping to compare optics at High Island, Texas event


I live in Texas. EO always has a ‘shop’ at the High Island Audubon reserve during spring warbler migration where EO displays binocs and scopes. There is always a very knowledgeable man representing EO there, too.

My question:

Is EO planning on displaying a Zeiss Victory 10 x 42 T HT binoc at High Island, Texas this year?

Red/green colorblindness has always been an issue for me in bird identification and now my 64 year old eyes may be dimming as well. I need all the light gathering I can afford. My reading says the Zeiss Victory HT binocs do a good job at that. I’d like to compare them to my $500 Nikon Monarchs. Honestly, I’m not sure I want to spend $2300 for binocs, but then again, it might be the best thing I ever did for myself, but the proof would be in the pudding.

While we are at it, do you have an EO binoc (more affordable for me?) that you would put up against the Victory?

Thanks for your help.

Dear Larry,
Thanks for your e-mail message.  EO Manager Ben Lizdas will be at High Island again this year! It sounds like you have met and talked with Ben before.  He will most certainly have the Zeiss Victory HT with him there, and it would be a great time to try that wonderful binocular.

The Victory HT is known to be one of, if not THE brightest binocular on the market.  It has a great feel in the hand as well.  There is nothing in the Eagle Optics brand that would compare to it, though the closest would be the Eagle Optics Golden Eagle HD 8x42 Binocular ($589.99) 

Another thing to consider is, 8x is easier to hold steady and has a wider field of view than 10x, and it’s also brighter in low light. That would be another good comparison to make at High Island.

If you don’t want to wait that long, we do ship free, and you can try it out during our 30-day return period.

Thanks for your business!

All the best,

Questions about Steiner Skyhawk Pro binocular

1. I would be so grateful if tell me between binoculars "steiner skyhawk pro 8x32" and "steiner skyhawk pro 10x42" which ones are more suitable for nature observation.

2. In your website, why have not you  mentioned where these two binoculars were made?(aren't they German made binoculars?)

3. Since these two binos are not fully multi-coated and ED, are their image quality inferior to some of low price binos, which are ED and fully-multi-coated like Vanguard Spirit ED,...

Best Regards 

Ebrahim K.


Dear Ebrahim,

Thanks for your e-mail.

We don’t carry the Steiner Skyhawk Pro binocular, and as far as I can tell, it isn’t offered for sale in the U.S.  I found a comprehensive review of that model here:  My assumption is that it’s made in China; as most binoculars under $500 (U.S. currency) are sourced out of China.

That being said, I can speak in more general terms about choosing a binocular size and magnification for general nature observation. 

8x is easier to hold steady, and the 8x32 would be smaller, more lightweight, and have a wider field of view than the 10x42.  Both would be about the same brightness in low light. 

According to the review I linked above, this binocular probably does have fully multi-coated lenses. However if it's in your budget, a binocular with ED or HD glass would be a better value and give better performance.

All the best,

Eagle Optics

How is Field of View determined?

Dear Eagle Optics,
Can you tell me how they figure out the feet at 1000yds on binoculars.
For example 7 X 50 equals 376 ft at 1000 yds. How do they get the 376 Feet.


Conrad A.


Hi Conrad,
Thanks for your inquiry.  The figure you are looking for is referred to as “field of view”.  This measurement can’t be calculated simply by knowing a binoculars size.  It’s possible to have 3 different binocular models all of the same size, with different specifications for field of view.  

The field of view is determined by a number of different factors based on how a particular model is designed.  Things that will influence field of view can be eye-relief, objective lens diameter, and magnification.  In general, lower power binoculars will have a wider field of view.

Like the weight of a binocular, field-of-view is one specification that you just need to find out for various makes and models.  If there is a particular model or models you would like this figure for, please give us a call.

Best regards,

Eagle Optics
