Jim,
Welcome to Rebreather World!
You came to the right source for a wealth of Rebreather Information.
Read as much as you can, and by all means do not hesitate to ask questions. Plenty of great Rebreather Folks here on the board more than willing to answer your questions. And who knows, maybe sooner than later you find your self strapping on a rebreather and give it a try!
Again, Welcome aboard!
RBN
