  I highly recommend using compressed air over oxygen. Nitrox 100 (pure oxygen) becomes toxic below 5 meters…

  1.6 bars partial pressure Oxygen is considered unsafe / hazardous.

    Nitrogen also becomes toxic, requiring you to substitute it with helium (or hydrogen).

      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.

        Yeah I feel like at that point ‘just’ invest in a submersible. Stay nice and comfy at atmospheric pressure in your iron lung
