Scuba to tank w/compressed Air

[FragTek]

For maximum results, you should have a 2 or more tank setup.

I have found the best way to get the most air into your HP tank from a scuba setup is to fill your hp tank first to 2000psi off of your first tank, and then switch to the other tank and fill the rest. This will result in higher fills each time opposed to taking as much as you can from one tank.

This of course is if you have access to another tank, or, you have just cut down on the cost of renting, so now all you need to do is rent one tank, and take yours in and have it filled.

If you can get ahold of a second tank, standard practice is to use "top-off" fills.

Use the first tank and then "top off" to higher pressure with the second tank. The second tank will be empties of less volume during each fill, and you'll end up with higher pressure in the tanks on your paintguns. You won't ultimately get more shots per SCUBA tank fill - nothing is free - but you'll get higher pressure on each fill.
