    quick math question.

    Ah too bad about weighty. I have painful neuropathy in my feet for which I take Opiate pain meds. I hike 5-7 miles a day in some kind of pain with each step. Every ounce counts. And size because I use hiking poles to keep some weight off my feet. Boy would I love that kind of FOV though.

    quick math question.

    Oh yeah. OK. :t: BTW what I wrote is true. And they have tablets with modern looking spacecraft on them. Now considering that every culture in history that I've ever heard of has had a creation mythology that basically says "we are the real deal, we are the chosen ones" I find it suspicious...

    quick math question.

    What about the use of a wider peripheral vision for picking up moving objects as in finding birds and then keeping them in view when they are on the move? That's a benefit for a wide FOV. Those little birds can be hard to track and stick with, not to mention butterflies and bees. At three...

    quick math question.

    Many here may think you are joking but I know from translation of the ancient Sumerian cuneiform tablets which are some of the earliest records of human writing that we were genetically created as a slave race to mine minerals for an alien race that still influences us to this day. What that...

    quick math question.

    That's the one. I bought it on a recommendation from Bluespiderweb and WJC. I wouldn't have really listened had it not been for that number 462. That clinched it for me. :t: I hope it lives up to the hype because I'm usually not a porro buyer.

    quick math question.

    I think I've got it.:t: So here's another one. Sometimes they only put the Fov in degrees. 7.1,8.1 etc. How do you get the Ft. Fov from that?

    quick math question.

    Never learned much math. My childhood was too chaotic to be able to pay attention to much at school. I do not remember how I passed any math class but I must have somehow. I can add and subtract, divide and multiply but that's about where it ends. It's amazing with the life I've had how little...

    quick math question.

    It is confusing as sometimes it's listed as 136 ft at 1000m. It makes me nuts sometimes. Look at my meopro. On the website it says FOV 384 ft. A 10x at 384 ft fov give me a break. That's not correct at all. It's something like 354 ft. This is on the Meopro website and also at Sports Optics...
