Hi Mike,
Welcome to Rebreatherworld.com
Nice pic, you guys look like one happy bunch having a great time on
Guam.
Well, you sure came to the right place to scope out what breathers are around these days. Plenty of people here on board who are willing to help and share information. Keep those questions coming, and sooner or later you will be joining the "dark side" of diving!
Again, welcome on board!
Enjoy,
RBN
