It is fitted with a needle valve. The IP of the O2 first stage is fixed, and set in factory to 10 bars, as can be seen on this image taken from the user manual.

I suspect the modification to reach 100 m is a matter of cranking up the IP pressure and probably changing that little red cap so it reads "100m".
Cool thanks for that.
It makes sense now because I am running 11.5 bar with the standard KISS oraface and thats just to give me normal degridation on the PP02 during the dive. I reckon I could get away with 12bar but Id rather have to top up than flush down.
Strange they rate it to a 100 but limit it to 80??
