Thank you for going back to graphics! I know you have a producer who wants to focus on the podcast format, but teaching things like this, a picture is worth a thousand words: I'd have never gotten this with 10000 words!
Purchasing a fluid head tripod makes it more comfortable when glassing from a fixed position for long periods of time. That's what we do when shooting long-range bean fields in SC.
Have you guys done any videos on aperature reduction modifying discs? Would love to watch a podcast discussing what you gain and lose by installing one. Lets say going from a 42mm objective to a 24mm by installing the reducer, and how that changes the clarity, field of view, chromatic aberrations, depth of field, good light and bud light, mirage, etc.
Thank you for another great podcast! I would love to see you guys do a 10 minute talk on the pros and cons of fixed magnification rifle scopes. Thanks!
For sure! Can definitely look into that! We do have a few that cover Prism Scopes (Ep. 164, LPVO, Red Dot, or Prism for your AR, and a #10MinuteTalk on Red Dots vs Prism Scopes). We also have a podcast all about riflescopes that touches on them as well!
What I need to know is I have 10x50 and I want to buy a pair of either 8x42 or 10x42 why lighter weight than my 10x50 and I would like better glass. Just FYI. I live in Iowa but hunt in Western States for Big Game. Are the Razor 10x42 really twice the Binoculars of the Viper 10x42 ?
To continue this topic you guys should cover the smallest resolution the human eye can resolve like Apple's "retina" concept, but expressed in MOA/degrees rather than pixels.
I still don't understand why apparent FOV is more useful than angular or linear FOV. I want to know whether or not I can see the whole deer at 60 yards with my scope set on 12 power. Angular or linear can tell me that but apparent cannot.
This guy has me more confused than I was before. I wanted to know if there were general design elements of a scope that determines what the FOV is but he just goes into how the image is presented. I understand that you are looking at a 2D image with the size of the screen determined by the objective lens size and the magnification. What goes into calculating FOV? Lens size and distance apart?
Product request, please do wide view scopes. More clearance to mount them, more space to cock a hammer, wider view, and they just look sexier. The supply of old Redfield wide fields is starting to dry up and prices are going way up on them.
Thinner edge vs thick ocular edge: Your brain actually makes up half the stuff you “see” in your peripheral, out of memory and imagination. You nearly only see movement and light in your peripheral. The thin edge just makess it easier for your brain to blend in the made-up stuff with the actual visual info. Like magic your experience is nicer
These numbers are really great unique selling points, specially if yours is better than the competition. I vote to have it on the box, accompanied with a small diagram to say why it’s awesome. First general public will just be “whats that”. All the sales guy has to say is: “it makes you see more better”. BOOM! Scope sold
Needs to be put in terms of relevance to hunting and military situations. You jumped into the weeds too quickly for my limited grasp of the terminology and physical dynamics of this field.
Hey Robert, we appreciate your feedback! Don't hesitate to reach out if you have any questions, we're happy to help clear things up for you however we can!
Another way to state it would have been "1 degree at 1,000 yards in linear feet is 52.5". Technically the conversion is linear FOV to angular FOV and vice versa, which was the point of offering the 52.5 figure.
@@mcdomik I respectfully disagree. Degrees are units of angle, not units of length or distance. 1 degree at 2769 yards "is" 1 degree. It isn't some length of inches or any other unit of length. Not being picky or snooty. It's just better when technical information transfer is done literally, not colloquially. When I first got into shooting and optics in a serious way and was trying to learn from all the different "experts" on UA-cam and from manufacturers' websites, I found it very frustrating trying to understand what they were trying to communicate, simply because they were speaking colloquially rather than literally. Take for example all of the UA-cam videos you can find going into all this detail and talking in circles describing "What is MOA or minute of angle." One even wrongly related it to minutes on a clock, and another related it to a compass. What? Gosh, it's just simply an angle that is one minute in size, one angular minute, 1/60th of one degree. Even so, I greatly appreciate everyone's time and effort being great guys and giving away their knowledge.
@@fog8969 In Sport Optics, there are 3 types of Field of View: 1. Linear 2. Angular 3. Apparent Here are the formulas for computing them: Linear FOV = Angular FOV x 52.5 * Angular FOV = Linear FOV / 52.5 * Apparent FOV = Angular FOV x Magnification * When at 1,000 yards (bins and spotters) - use 5.25 when at 100 yards (riflescopes). When an optic has a linear field of view of 390 feet at 1,000 yards, what we're saying is that the diameter of the circle is that many feet across when observing something at that distance. Think of a drawing of a subtended angle and at some distance draw a straight line across it - it's the linear length of that line. This same linear number can be converted to the subtended angle as you say with the number 52.5. With 390, it's 7.42. If you look at any Sport Optic manufacturer website, you will see you can convert the linear, angular, and apparent using these formulas - I didn't invent them; they're an industry accepted standard. Randomly picking Maven Optics and their B.2 9x45 binocular, they list the following FOV specifications on their product page: Angular FOV = 7.2 degrees Linear FOV = 377 feet at 1,000 yards 7.2 x 52.365 = 377 (industry accepts the rounded 52.5 figure) Note: See page 83 in Sport Optics by Alan R. Hale Let's say you have a binocular that you don't have the FOV specification for. You can set a yardstick 10 feet away from it, note how many inches you can see from one side of the field to the other, and then use a proportion to get the linear FOV at 1,000 yards. The angle is the same all the way out to infinity, but the linear changes depending on how far out one is observing. The 1,000 yards for binoculars and spotting scopes is just a standard distance that was chosen decades ago.
For sure! We don't have a podcast dedicated to that topic specifically. We do touch on it a bit here: ua-cam.com/video/WNb1Ezyylfs/v-deo.html But we'll be sure to get that topic on the list to dive into a bit deeper! Thanks for the suggestion!
Another excellent Midwest 10 min talk. Very interesting, thanks guys!
Thanks for tuning in!

Glad you found it helpful! Will definitely take that feedback and see how we can work more helpful images like this into future episodes.
Amazing discussion around Angular FOV. Learnt a lot from this.
This was always very confusing to me. He explained it with such simplicity I now understand. Great guest today.
Mike's the man! Thanks for tuning in!

When the talk is good the minutes don’t matter
😂 😂 We feel the same way

he took 8 minutes to explain the difference between the angular width of the image being captured, versus the angular width of the image experienced.

Hey Jonathan! Often times things like Field of View are listed on the box of our binoculars 👍
Luv it '' 🙂 💥💥💥💥
I definitely prefer a scope with little or no obstruction around the edge. Its just a better viewing experience.
Video games with radar can help with visualization on some of this conversation.

"10 minute talk"

We tried.
1 degree at 1,000 yards "is" 1 degree. It "subtends" to 52.5 feet.
Yes - that would have been a better way to state it.

Linear FOV is essentially the base of an isosceles triangle, which also has a vertex angle.

Expert?
I'm your Huckleberry.
“Yea it does”. Has no idea what the guy is talking about because he is all over the place. Talking about relative to 360 or 180 degrees. Lol
