I've gone 3 outings on one tank, approximately 6000 rounds. Razor : : 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
