Second, is the quality of the 2yr/300 dive hour maintenance service the factory performs (if you choose to send it back to the factory that is). It's not the cheapest, $62.50/yr compared to the $50/yr my wife pays to have her Scubapro serviced at the LDS. A little more if your reg. is enviro sealed. But what they do to it is ridiculous, in a good way of course. You basically get back a brand new looking reg. Everything from the purge cover to hose strain reliefs are replaced.
So the factory overhaul is $125.00? How much for a 2nd stage only, or a SS1?
I just want to say that offering a factory overhaul should be the deciding factor in purchasing a new reg for anyone not actually working at a dive shop. It means that the company (Atomics) unlike any other company making scuba gear, will actually be availing themselves of the real world testing done on scuba gear every day, by actual divers. I am assuming that that was what got them to put the castle on the diaphragm retaining ring, for instance. Their own techs got to experience the joy of trying to make the soft purge cover grip the sand locked retaining ring to get it out. And so they updated the design to make it easier to disassemble.
By comparison, other manufaturers put teardown procedures in place when introducing the gear brand new, and teaching the gear tech classes with gear that never gets wet, and never have to deal with the fact that those tear-down procedures just do not work on reasonably worn gear, or sand-jammed threads. Which forces gear techs into grinding their own removal tools, etc etc.
(I still don't get why Atomic does not make a spider tool for the SS1 exhaust valve, though, which also gets sand-jammed. At least use the same pattern as the Air2 so we can use that spider tool without having to hold our breath that we do not rip out the spiders with a needle nose.)
And as a side benefit, factory overhaul means that maybe, just maybe, some stolen gear will find its way home.
(I bought my mk15/g250 twice. Once direct from SP, once from a local dive shop that sold my stolen reg back to me.)
