Since I'm feeling particularly lazy, but also particularly curious, and I'm SURE than some physics geek out there will just DELIGHT in this sort of question... Knowing that PV=nRT, and given a 122ci 3K psi tank, and a 80cf scuba tank, presumably also at 3K psi, and assuming a perfect fill , that is, absolutely no lost air from hoses being released and whatnot, and a best pressure in the paintball tank after the fill(presumably the optimum pressure will drop slightly with each fill).... I would like to know what the pressure in the paintball tank would be after each successive fill, and how many realistic fills one could get from a full scuba tank. Any takers?  I mean, people say they can get ~7 paintball tank fills off a scuba tank fill, so I would like to know if it's honestly worth it for me to get a scuba tank and the appropriate fill gear.  And no, I don't want someone to TELL me it is.  I want to see the numbers... so, if you would like to do this, please respond with a list of numbers for pressure after each successive fill of the tank.

Any takers?  I mean, people say they can get ~7 paintball tank fills off a scuba tank fill, I've seen these numbers on a website before (sorry can't remember...yahoo search maybe?) but anyway you can't, according to them, get 7 complete fills. I think it was more like 2-4 complete fills, 2-3 2K+ fills, then 3 or 4 1500psi fills....... hope that helps....even if only a little. They were recommending the cascade deal with two tanks. T

get the fireman 4500 psi tanks..2 of them will fill 3 guys all day long for 2x out.
