Just wanted to say hi and what a great site! I'm new to rebreathers, in fact I've just completed my class and will be doing my checkout dives at the end of the month. I'm looking for some input on Drager Dolphin(s). I think it should be just right for my needs. Anyone with tips, tricks, cautions, etc. would be great. Thanks, FD.

Welcome to Rebreather World. I dove a dolphin for a year or so. Just tried it again for old time sake. Still works pretty well.
