are you going to keep the old pony?
I am pretty sure I will keep the 19cu ft for shore dives and travelling....I am 90% sure I will be taking this with me when I go in August to South Africa.

As I didn't want to run the risk of voiding Nems "warranty" I couldn't establish the exact cause of the failure but just checking the IP (Intermediate pressure or the pressure of gas that is delivered by the 1st stage to the 2nd stage) revealed that things were not good.
The IP was creeping with no upper limit, I purged the reg before the IP reached 18bar to prevent damage to the IP gauge and hoses.
When the reg was breathed the IP dropped by almost 6 bar (which is an absurd drop). This was the reason for the laboured breath whilst submerged but not the cause.
So there are a few likely causes for this and I'll wait till Nem hears back from the supplier rather than speculating.
It is a very good example of why divers shouldn't be treated like children by the dive industry and be provided with the knowledge on how to check the "dive readiness" of their gear, these checks involve no disassembly or adjustment. Remember these regs of Nems were straight from a shop! For the cost of an IP gauge ($30) and the knowledge of what to look for Nem would not have had this unpleasant experience. (thankfully he was shallow, as depth would have exacerbated the problem and the reg most likely would've "locked" deeper than 20m, and thankfully he also had attentive buddies..)
Don't assume that handing money to someone guarantees they will do a good job!
