One of the key questions we address is power vs. objective lens size. Learn how the numerical values like 10x42 or 8x56 translate into real-world experiences, affecting your field of view. Cody also explores the correlation between power and field of view, revealing how higher power can narrow your perspective while lower power widens it, using examples like Vortex Razors.

Dive into the details of the objective lens, the vital component that influences brightness and clarity. Discover the significance of millimeter measurements, from 32 to 56, and how they impact your overall viewing experience. Cody unravels the concept of exit pupils, shedding light on why certain binoculars deliver a brilliantly bright image.

Beyond the technical aspects, Cody walks you through the practical features of binoculars. Learn why it's important to know about eye cap covers, flip-up objective lens covers, center focus, and diopter settings. You'll also discover the versatility of binoculars with a quarter 20 thread, allowing compatibility with various adapters and mounting options.

Whether you're chasing mule deer, elk, pronghorn, or birds, understanding these fundamental aspects of binoculars is crucial. Cody's insights extend to tips for eyeglass wearers, explaining how adjusting eye cups enhances the perceived field of view.

Thanks sir
*Summary:
10x42
10 = 10x optical zoom
42 = 42mm Objective lenses diameter
2nd/1st number (42/10) = exit pupil (lerge number means more light) in nomal light, value 6 is perfect. But if you want to explore night sky you can go as high as possible/you want.*
It was just what I need to know

[UpInSmoke]

Best, quickest and most useful video on binoculars I’ve seen. Thanks for the great info.

[anderspan]

This video is exactly what I was looking for. Thank you sir

[lukejensen]

Incredible video. I've been hunting for 30 years and never new a lot of the things you clarified, thank you for taking the time to make this video.

[pejuangdunia]

I'm a newbie, bought a bino last month i.e 10 X 42 . Love it.
Considering buying an astronomical bino 25 X 70 in the future .
Thanks for the explanation

"Eye Relief" is the "sweet spot" distance for your eye from the ocular lens. It's important for astronomers.
The diopter is for people that have eyes that are a little different. You look through the right side, then adjust the left diopter to match, so you don't get a headache.
15x or more magnification is good for gun scopes, and 8x is better for watching baseball, races, golf, etc.

Thanks so much for doing this video
that's not half an hour long !
Just what I needed to know as a noob .

[frosty]

A good effort. For eyeglass wearers with compact binocs, 8x20 10x25, check the eye relief. some are too short to work with glasses. Most larger binocs do not have that problem.

Also the power does not just effect the field of view but the apparent steadiness of the image you are looking at. A 7 power image looks much steadier than a 10 power, the size and weight of the binocular may help.

The exit pupil for good nigh/low light vison is 7mm. (The standard for night binocs was the 7x50.) The older you get the smaller your eye's pupil will open. This may be more for rifle scopes, but the larger the exit pupil the easier it is to see though the optic as the larger exit pupil will give you a little more "wiggle room" for eye alignment. That dark cresent you see when trying to look though the optic is the missalignment of you eye with the exit pupil.

Optics have gotten really good and the "bang for the buck" is orders of magnitude better than decades ago. If you plan on needing binoculars, go with the best you can get as they will serve you well, perhaps for a lifetime, and will reduce eye strain and make using them for long periods of time much easier.

The joy of quality remains long after the sting of the price is forgotten.

No I do not sell optics, I just dislike trying to use cheap crap that is not worth the effort.

[FreedomstCenturi]

Awesome. Recently got into hiking in the wilderness and decided it was time to buy a pair of binoculars for general viewing. Thanks

[hl]

Purchased my first binoculars last week. Thanks for a complete, easy to understand and calm explanation.

[BeckVMH]

Thanks for focusing on the necessary points. My understanding was a bit blurry, but it’s much clearer now! Haha thanks man, great vid and what I needed.

[johnnywatson]

Never knew what exit pupil was and it makes perfect sense. Awesome to know. Thank you. Good content.

[sheerwillsurvival]

Bigger the objective lens better light gathering capabilities mean better low light vision better early morning late evening viewing only drawback is size and weight especially with good glass oh yeah and cost

[MadCatMaddie]

Fabulous video. Great information for people with 0 knowledge of binoculars like me.

Thank u sir.

[Zach-rxzg]

This is by far the best video Iv watched to learn about binoculars

[russellroberts]

Outstanding job, sir! Told me exactly what I wanted to know without any bull.🤠👍

[AnkushKumar-yyiv]

Thank-you Very Much Sir for your Great clear cut concepts

[Stealthypanda]

Exactly the video I was looking for, background music is a bit loud but thanks for the effort and time you put into the vid! I’m looking to purchase a pair of binos for watching college football

[denisesalles]

This video is amazing, spectacular, and dare I say "eye" catching? Wow, I had no idea about the numbers or exit pupil, etc. You are an awesome presenter and speaker. Thank you!

[cruiserjohn]

I learned something new.
Thanks for sharing this.
