| Re: How many hours from a Prism with 19 cft tanks? I think I need to specify more assumptions. The 19s will be full to their maximum rated capacity (not short-filled), I will have no bail-out bottle (so I need to surface with an emergency contigent reserve), and my drysuit and buoyancy bladder have no separate supply (just use gas from the diluent tank). Then, the next question will be, well, how much more time will I get if I do bring a separate bailout bottle? |
