Help with Scuba Tank Appreciated

[Not_Again]

I am looking at a spare tank for a couple of shots so that I can spud on the go.

The specs are here, and the tank is $90 with valve setup.
Features of this fantastic item include:

* A must have for your dive
* Comes with a yoke design valve
* 6 cu ft.
* Pressure: 3000 PSI
* Length: 10.80"
* Diameter: 3.21"
* Weight with valve: 3.14lbs

My project is a golf ball gun which will sit in my golf bag, (already been done I know), so this tank is about as big as I can fit in my golf bag.

I was looking earlier for posts on scuba tanks and people that adapted them for this use but am looking for more input from the community. Theories, comments, how-to's, are all welcome . Thanks again

sounds good, make sure its from a reliable seller.

first you will need a reg to bring down the pressure so you can use it, you can use a scuba reg or a palmers inline reg configured for high pressure. unless you already have a scuba reg and hoses it would be cheaper to go with a palmers reg. with a palmers you will also need a scuba adapter and a remote line. would also recomend a safety popoff valve.

i would use a high pressure/small chamber design with a QEV possibly to keep it compact enough to all fit in a golf bag.
