Per the OP, please keep to the subject. This conversation has nothing to do with what you think about the viability of an Air2.
......perhaps those AIR2 thingy's SHOULD be made illegal though ???
As strange as it may be, we occasionally run across these things here in the U.S. For example; Laguna Beach, CA has an ordnance requiring divers to have a snorkel. Lifeguards are authorized to issue a citation and prevent water entry if you don't have one.I've never heard of this either, I can't imagine any government would start to make laws about specific pieces of diving equipment.
Do you think there's a country that could make jacket BCs illegal? I'd be tempted to make a small political donation.....
