Configuration "Mode A": Blocked First Stage feeding both solenoid and orifice.

<snip>

Mode A is the "normal" one for anything shallower than about 240 feet.
Just to confirm- the rEvo solenoid can happily run at 9-10bar or more? (Assuming you need 9bar or greater IP (lots of people at 11-12.5bar) to dive orifice equpied MCCR to 240ft just to keep the flow moving?)

While I cannot complain about having two different modes available I think the goal should be to make a safe system- in my mind the safest approach is to have a unit appear to run exactly as a MCCR with the solenoid and software waiting and watching in parachute/watchdog mode to start beeping/buzzing first then firing secondly should the unit for whatever reason fail to dive with MCCR parameters.

To me the ability to alter the unit to run as pure ECCR would be of no interest, better to fix the inherent shortcoming of MCCR (depth ability- higher IP, smaller orifice, if that is what you desire to run ECCR for), also task loading (get a decent HUD) hands free operation (set IP correctly or fit a SNOG ) than to fall back on electronics for the sake of it.

Of course this assumes that the "MCCR paranoia" is what makes them inherently more closely watched, so far apparently safer... not that I wish to reignite that debate
