Re: brownie third lung or hukah
Trained and qualified can be taken many ways. I have taken the advanced class only. Which I can tell you does not prepare one for 160 feet. But I have also done quite a bit of self-teaching. I have read several books on the subject, talked to lots of people. And I worked my way up to it, 60-80-110-120-150. I reccomend it to anyone not who feels they are prepared, but who knows they are. I was well aware of all risks involved. And for the record, I did have an incident. My newish dacor regulator free-flowed! I will NEVER forget that experiance. I am glad that I did do all that reading and other dives past 100 feet. otherwise I may have taken one too many gulps of water while fumbling with my other tank, which had a torn mouthpeice. in the end I borrowed on from a buddy, which happened to be my instructor/friend accompanying me on my first deeper deep dive. In short you are right to be prepared and well informed, but I personally think that a "certification" means nothing. How many people drink their way through college and still get that little peice of paper that say they are smarter then the rest of us??<br />Craig
