Re: How many hours from a Prism with 19 cft tanks?

It becomes more about number of dives than duration - it's the descents that chew dil and the ascents that chew O2. I normally run out of dil before O2 - using dil for wing inflation if I'm doing a few dives.

Single dive - then 6+ hours would be completely feasible (If I ever decide I can tolerate a 6 hour dive that is) with a comfortable margin to spare.

Multi dives, then a couple of deep dives is fine for a couple of hours each. Shallower (air dil range) I'll do three dives in a day of an hour or so each. Perhaps a couple of days on the scrubber but normally fill tanks of an evening. Then again I'm a bit cautious and figure that gas in the tanks is a good thing to have. I've got in for a shallow pier dive with 50 bar O2 left, but I'd probably not jump off the boat with this little gas.
