A few more questions: Do I need a special inflator hose and/or corrugated hose for the AIR2 or SS1? Which one works with regular hoses?
I've done some reading on these units, and it seem the SS1 is considered a good breather, and the rest are considered poor. Is that still the case? How does the current (4th generation) AIR2 perform?
How deep is it safe to take these things?
The SS1 comes with three different size adapters so that it will fit virtually any corrugated hose.
I have been down to 105 ft with My SS1. I like them better than the AIR2 that I had on my ScubaPro Knighthawk BC. I switched the Air 2 for the SS1 while I still owned the Knighthawk BC.
I lost 53 lbs and needed to by a new BC. I came down to either the Knighthawk or the Aeris ATMOS XT. The ATMOS XT fit better so I went with IT. We simply switched the SS1 over to the ATMOS XT and put the AIR2 back on the Knighthawk that I will be selling.
I really like the fact that it breathing capability is close to the Atomic B2 regulator I use. I also like the fact that it makes it a no-brainer to rinse out the inside of the BC at the end of each dive day since you simply unscrew it and pour fresh water in through the corrugated hose.
Also, the SS1 only needs to be serviced once every two years or 300 dives (which ever comes first) while the AIR2 needs to be serviced every year and carries a 1 year warranty. ScubaPro provides free parts if you have it serviced every year, Atomic does not. The Atomic warranty is for two years and is fully transferable while the ScubaPro warranty is limited to the original purchaser.
My daughter was certified last May and uses an SS1 and my wife will be starting her OW classes in January and she will also be using an SS1.
The purge button on the SS1 is also much large that the one on the AIR2.
My local LDS has not had any SS1 units that had to come back for servicing within the two year warranty period.
My understanding is that the engineers that started Atomic actually came from ScubaPro.
