This is how it works the Pelagian, with a needle valve you can reach and regulate during the dive.
In the voyager the flow is pre-set at surface. You are teached that you cannot change it during the dive.
Yes, that's correct.
I agree.
No, i tested how the needle valve works at the surface with flowmeter and manometers for showing a friend that he was teached wrong, so i know how does it works, but i didn't used it in water, because i don't like in this machine.
if you isolate the reg from pressure it is a kiss...
I am sure that when they say scr/ccr it means that one can add a cape to the reg to get a fixed MP and dive the rig kiss style.
it must be certified as a SCR and divable as a kiss with a discreet modification.
the system you discribe can't be dived CCR, if the diver can't reduce the flow rate going down the ppo2 will sky rocket unless one tunes the flow rate to nearly nothign clos the surface to reach 1 liter minute at the botton whcih is stupid because this near the surface that we need the flow rate to be as close as possible to our methabolic consuption.
you also mentionned that the flow rate could vary from 0.5 to 25lt/minute...it looks like a scr flow rate...I'd like to read the certification, it must be a scr certification.
