IMHO the proper fix for this is for the controller firmware (for eCCRs anyway) to insist on validation of the sensors on some rational schedule (e.g. weekly) before it will permit the setting of hyperbaric PO2s for control purposes.
However, to the best of my knowledge there is no current production unit that does, so this leaves it to diver dilligence.
So Karl, ket me see if I have this. You are anti training and feel that our training system has completely failed to make Rebreather diving safer so you would rather make the RB units themselves idiot proof and they will be designed to protect us from ourselves.
Building idiot proof rebreathers will just create superior idiots don't you think?
