In general I'm also not a big fan of Cressi regs, but as fleet regs, what could be possible a problem with the AC2-XS2?
They are cheap, strong and reliiable (here my customers got them for 105,-US$, 1st & 2nd stage).
They can be adjusted to the same 1,0inch/h2o as similar models of SP, Oceanic, Spirosub and others.
The 1st stage IP can be adjusted with a very exact with a nice screw system.
I never ever had to repair an AC2 1st stage orifice, it's an incredible hard orifice, but I had to repair hundreds of other 1st stage orifices like the MKII.
For me personally is the breathing comfort of the SP (R....) and Oceanic (Alpha......) 2nd stage models in general a bit better, but on the Flow Bench the Venturi is better balanced as in other models (no massive Venturi Override).
The grid in the cover of the XS2 breaks a lttle bit too easy, but spare parts are cheap with Cressi.
So when servicing the AC2-XS2 I'm also testing them, but of course I can see only over time how reliable they are, and for me they are reliable.
They don't come more often on my workbench than other brands.
I'd like to know how the reliability was tested just to have an idea how one can come to the conclusion that all Cressi equipment is not reliable and substandard.
I haven't found out of which regulator model Burhan is writing, I personally had a lot of problems with the Eclipse 2nds, I don't like them, but what could be a problem with the AC2-XS2 Cressi Sub regulator?
For me it's a great value for the price.......
I also like BCDs, fins and masks from Cressi, how have they be tested to come to the judgement that they are substandard?
I understand that one maybe cannot publish the exact number of tests, but I would be interested just to know how the test procedures were conducted, that should not be a secret, right?
