Thinking about 130cf tank (X8-130), please help me confirm what i'd need?

A local scuba shop has this tank for $360 so it's a half way decent deal.  130cf, 3440psi, $7 per fill up.  I'll go check out the tank this coming Monday'ish.

It's a Worthington X8-130.  http://www.leisurepro.com/p-xsshp/xs-scuba-worthington-cylinders-hp-steel-3442-psi-230-bar

Based on what you guys have mentioned, and just looking at the valve from the pics, seems like I would need the "DIN Charging kit" from here?? http://www.airhog.com/A9_Charging_Kits.html ??

and then get the "Foster Female Quick-Disconnect to 1/8" BSPP Male, 5000 PSI" of some brand to connect to the gun?

would that be it? or am I missing something?

What do you plan to use it WITH?  If you plan to fill a 3000 psi rifle you'll get very few fills.  Each time you fill a gun you deplete the tank a bit.  You also need to take into consideration the volume of the gun you're filling - more volume means less fills.

can you tell me what "very few" means if I plan to fill the MRod and Disco? For the MRod, I only plan one session per day, taking 30 shots.  probably bring the psi down from 2800 to 2200 (i'm hoping?, might need that BLT tune)

I know it's only 3440psi but I was hoping the 130cf means there's a lot of air inside so it would be equivalent to a 40cf scba tank that is 4500psi, no??? if that's the case, that'll give me one fill per day for a month.  That's 7 * 12 = $84 per year for fills

You can use the calculator here:

It seems if you actually get the tank filled to 3440 pounds - depends on who fills because after filling it will have to sit awhile to cool down and equalize temp to the surrounding temp so the pressure gauge will read correctly.  Don't be surprise if it reads close to 3440 when you leave the fill place and it's down to 3200 when you get home.  What I'm saying is that you can't rely on getting it to it's max fill every time.

I have a 4500 psi CF 100 ci tank.  When I took it to get filled the gauge read 4500 when they handed it back to me and then was really around 4200 or so by the time I got home.  Air heats up when compressed and pressure readings change.  I don't have that issue now as I fill my own tank, allow it to cool and then top it back off.

But assuming you do get a 3440 fill, using the calculator above it seems you could get about 76 marauder fills using 215cc reservoir, fill to 2800, refill at 2200 before the 3440 tank gets to 2800.
