Hi
When I was making the decision to go CCR I added up the costs honestly and I estimated I could easily save £900-00 pound Sterling per year on gas bills
5 years later I have a free Inspiration and I am in profit.
It's nice to win sometimes.

I basically did the same.
The real kicker for me is when you've filled several sets of doubles, stages, etc. for a deep live-aboard that gets blown out. Now what? Do I dump the gas because my next series of dives are only half as deep or do I dive a hypoxic mix on a shallow dive?
