: i was wonderin how many fills i could expect with like a 70 cf scuba tank at a 3000 pound fill? I understand that the maximum pressure decreases slowly but i was just wondering like a rough estimate on the amount of shots, or fills : THANK YOU THANK YOU It depends on the size of the tank being filled (45ci to 114 ci). If you only have one scuba tank, you'll probably need to fill it every week. With 2 tanks I'd need to fill every 3 weeks or so. The advantage with 2 tanks is that you can cascade - first fill with the lower tank and then the higher - that way you fill the first 1500/2000 psi from the lower tank instead of sucking the pressure down on the high tank just to fill the lower end. If you have a friend with a tank you can get together and do this, it'll help both of you get more fills per scuba. Tom
