IN FACT, i have plan to order either a great white 97cu tank or Tiger Shark 72cu from (Joe) http://www.airtanksforsale.com/ ,,,, but still haven’t made my decision ,,, but i have to buy this tank,,instead of buying an air compressor as you said,,, it is better ,,,you are right,,,
My dear Hemn…
I own a steel 150 cu ft steel dive tank. It is half again as large as the 97 cu ft tank. If you check Ebay, you can sometimes find a 150 cu ft scuba tank in steel for 200 USD. I believe Faber is the brand.
The smaller scuba tanks will need filling much more often. Depending on the gun’s air tank volume, I can get about 30 fills from my tank.
A much better solution, in my humble opinion, is to purchase a carbon, or glass fiber tank, of the largest size you can afford. Since it can be filled to 4550 psi, it will offer many more refills than my steel tank, be much lighter, and will be less expensive than buying/maintaining an air compressor at home. That is true only if you have easy access, at an affordable price, to a station that will fill the 4550 psi tank.
A glass fiber tank is expensive, but it is in the middle of the price of buying a large steel scuba tank and buying your own compressor.
