Thanks for the info...
It would seem that the Inspiration and Evolution then are in the minority of production eCCRs (don't know about the Prism) in that if you jump in with handsets off they will not come back on again due to a pressure / water switch.
Given that there must be power running to the handsets to allow the "soft" switches to work I wonder why APD went down and have subsequently stayed on this path?
I personally would prefer to see the handset switching on automatically... and other than maybe it burning through batteries faster is there any other reason why they might not have provided this function?

Hello Steve, FWIW, the Prism has a hard on off switch, which can and is used underwater by most of us when we fly manual. But the passive/analogue 2dry will show PO2 at all times as it's powered directly off the cells, nothing to turn on there. So jumping in without powering up is not a problem as long as you check your 2dry and switching on the unit underwater takes less than a second and the solenoid fires twice on powering up. The switch is a big magnetic reed switch that's usually mounted on the BC inflater, easy to find.
IMHO, if the unit is not able to be turned on and injecting within a second while underwater, it should definitely have a wet switch. If you jump in without powering up, you shouldn't have to scroll through a bunch of screens to get your PO2 and start the unit injecting... -Andy
