David P:narced out of your gourd at 100 feet? I have heard of very few PADI classes that take the students below 100'
gas supply management is something the student should be doing their very first dive during certification
losing the ascent line, they are with the instructor right?
LOL. You haven't read some of the deep AOW dive incident reports around here, have you? He's talking 130 feet where you can easily get narced out of your gourd, especially if you have a current on the wreck and have to fight it. I'm sorry, but AOW doesn't prepare one to dive 130 foot wrecks. There is no "gas management" in the PADI AOW manual, much less for someone who doesn't have a clue have quickly you run through gas at 130 feet. Doubles makes sense at that depth.
