Hi Stuart,

great article.

My comments:
Bailout via open loop as prefered method.
I doubt that open loop breathing, which has higher WOB than a BOV or normal regulator, can be used in case of a CO2 hit. In case of a CO2 hit you will initially overbreath even the best regulator. Any extra WOB is not wanted and will increase the problem. For me a BOV is the preferred solution.

eCCR as a parachute only (flying it manually)
Flying an eCCR manualy has a higher task load than mCCR. Manualy operating the eCCR certainly needs to be practiced as a skill in case something happens to the solenoid, but as SOP?

You don't have the continous flow that you get with a mCCR. Therefore, there wil bel more deviations from the setpoint, since more manual interventions are required. So, if you are diving without integrated deco computer, how valid will your deco profile be?

I bought rebreathers for deep filming. In my case, manual operation is almost impossible. I have only two hands and both of those are on my camera. But even without camera, I run my Vision on automatic (except during long deco stops). It allows me to enjoy my dive more.
