| Re: How many hours from a Prism with 19 cft tanks? This sounds like a good question for your instructor. He will know the specifications of the unit based on the scrubber material your using. However, with 19cf bottles, your scrubber should be the limiting factor, regardless of depth and temperature. Any dive greater than 30ft I would recommend bailout.
