Speaking of old chestnut...

Some people are concerned about the additional connection (to breath on-board O2 as OC) to be a potential failure source. If the loop is intact but all O2 is lost, then the unit is potentially useless (unless you could plumb in off-board deco gas = another connector failure source)...

And so on, and so on...

And they are right to give it consideration. I did.
The Dil and O2 go to a gas switching block which feeds my BOV. It is default switched to the dil for sanity breaths. If I need it at 6m then a quick switch. If the BOV or GCS to the BOV fails then I only loose the dil. Ho hum.
Failure of the pipework to the switch block or the switch block itself is an acceptable one to me. Then its off to the stages and out of the water sharpish.
I dont think hanging a reg off the inboard o2 is a good idea without a flow stop. Even then, I prefer my way because the pipes are short and well protected in this little frame thing I have.
