I currently do (strictly rec) single-tank dives in the Monterey area with HP100 steel tanks filled to ~3442 psi. I have heard that filling LP tanks (2400 psi or 2640 with the + rating) up to ~3500 psi is very common in some places of the world, such as Florida cave country. The result is a smaller tank containing a lot more gas than my HP100's. It's my understanding that this practice is safe for divers (read: nearly no more risk vs diving an HP tank at the same pressure). Rather, it is the tank filling operator who takes on additional risk, since there is a non-zero chance of tank failure during the fill.
My primary LDS's operators don't do this. Are there any dive operators in the Bay Area who do these "cave fills"? If so, I might consider picking up some LP85's (or similar).
Thanks.
