Thanks Thom, glad you liked it.
For now, the stock handset has been left in place. I just strap the hadset to the dilluent bottle and forget about it. It's disconnected from the o2 cells but the molex are there, tucked between the cells ready to use should something go wrong with either the shearwater HUD or the Pursuit. In this way it's not a secondary or tertiary, it's a back up, not to save the dive but more to save a trip, as you'd need to get back to the surface open the head, and put the batteries in and plug it in to the cells before it would be useful.
Looking back on it, I'd also be pretty comfortable just adding the shearwater HUD to the copis and having a stand alone deco computer. The shearwater HUD is a brilliant piece of kit for the mCCR diver!

Hi Gill,
Nice write up on adding the Shearwater. Did you leave the original PO2 monitoring in place? I saw the cable in your head but didn't see the 3rd wire in any of your molex connectors.
