Dennis, As I wrote, I (and all the other teaching staff) use their own gear for the pool work. Just about everyone has "pool gear" and "OW gear" -- and my "pool gear" is the BCD I bought during my OW class (SeaQuest Balance with AirSource inflator) along with a very simple reg (Scubapro Mk2 & Dive Rite 2nd stage).
The idea is that yes, the pool's chlorine WILL "modify" the pool gear and the "good gear" is kept for real work.
