I serviced this stab jacket and Air2. The air 2 has a factory rebuild kit in it, for the 2nd generation of AIRs, and works like a champ. I've also rebuilt the hose and the hose comes with it. It's a medium, which fits me in a wetsuit. I'm 6 feet tall, 195 lbs, 44 inch chest.
The BC and Air2 work like a champ. I've used them for my summer diving here, but this BC won't fit over a drysuit so I'm back onto Ebay for something a little more adjustable. This BC works amazingly well though.
I'm also going to include a 2nd AIR2 factory rebuild kit as an extra gift. The first one is in the Air2, freshly serviced.
This needs nothing. It looks like AIR2's go for about 100 bucks on Ebay.
100 bucks here gets you the BCD, the AIR2 hose, and the AIR2. Hell, the hose is 30 bucks on Ebay or online by itself. I also put a XS scuba retractor on it to keep stuff from dangling. You can have that for free too.
100 bones OBRO.
