I need supplemental oxygen at less than 1 fathom under water, if I stay there long enough...
I highly recommend using compressed air over oxygen. Nitrox 100 (pure oxygen) becomes toxic below 5 meters...
Nitrogen also becomes toxic, requiring you to substitute it with helium (or hydrogen).
Interesting talk on the subject: https://youtu.be/skL5EQa8DFY
It's why I'll always remain happy with recreational diving at depths less than 40m :) Tech divers are a bit crazy imo. Sure, there's nice views to be had (if you bring a lot of light), but it's not worth the risk for me.
