If I was not confused before I am now. Thanks guys. I think when I get to South Florida I need to sit down with some well experienced Rebreather divers. and an instructor. i will be there in a few weeks. Help clear out the fog before I lay out a lot of money.
Join the Florida South Coast Rebreather Underwater Bounders (S.C.R.U.B), the world's largest and most active rebreather dive club, for some dives while visiting South Florida. We allow bubble blowers on many (though not all) of our dive outings. That will give you a good chance to observe the real world of rebreather diving.
Talk to our members, whose experience levels range from "just certified" all the way through experienced technical rebreather divers and instructors. You will also have a chance to see a good variety of rebreather models in action.
Read Jeff Bozanic's Book, which is sold under the titles Mastering Rebreathers or sometimes Understanding Rebreathers. Order Back Issue 25 of Advanced Diver Magazine, and read my article, "Transition to Rebreather Diving." Attend a "demo day" to try out some rebreathers under the supervision of an instructor.
If you do these things, you will be in a good position to decide if a rebreather is the right choice for you.
