Whirling Girl once bubbled...
Well, all water in Puget Sound is cold, low vis water.
And let me correct myself, I can't actually remember if it was 130'. It was somewhere between 110' and 130'. My instructors, as I have said many times, were very good and I like them alot. I think they were teaching what they were told they were supposed to teach, and what they were told was safe. I am starting to disagree.
I have not taken 'Deep Specialty' training. Have you? What do they teach you in that specialty? How much class time do you spend? What do you learn about narcosis and PPO2 and all that stuff that's different?
Do you believe that, after taking 'Deep Specialty' training, a diver is safe to dive to 130 feet on air?
I took SSI's "Deep" specialty in my AOW. We learned basically nothing of significance. O2 partial pressures never came up at all. The only real information in the book was "you might want to consider a secondary air source such as a Spare Air."
