About 6 years ago, I did a dive to 170' on a wreck off Catalina Island. It took me almost two minutes to figure out that in order to run the reel, I had to loosen the T-nut that held the spool down. Real smart. It ranked right up there with the rest of the dive: No buddy, independent doubles, and a Zeagle "Tech" (yeah, right...) BC... Duh. Perry "I got smarter" Armor -----Original Message----- From: Don W. [mailto:donw_s11@sw*.ne*] Sent: Monday, October 11, 1999 12:59 AM To: techdiver Subject: Save me... Okay... so maybe I'm just getting bored with the latest threads on converting the US to metric units... or not. Tom Mount (IANTD) says he's personally comfortable to 170 feet on air. George Irvine says you're stupid to go deeper than 130 feet on air and probably shouldn't go _that_ deep. Numerous people have died trying to push the SCUBA record of deep air to 500 feet or so. Question for all of you... What unexplainable stupid behavior have you seen from your dive partners diving between 80 and 170 feet (on air) that would indicate that they were seriously f____ed and didn't know it? Where are some good chamber studies with less subjective results than a binary win/loss chess game indicating the progressive loss of mental function at high nitrogen partial pressures? Where are some good chamber studies which eliminate the nitrogen and study the progressive loss of mental function at high oxygen partial pressures? The questions are clear, and I challenge all interested academics to produce the citations, or think seriously of the simple indicated experiments... Why does the issue of impairment due to high nitrogen or oxygen partial pressures continue to be an item of debate within the technical diving community? Hope this generates some good discussion, and either gets someone to cite some papers, or do some chamber experiments and write them. regards, Don W. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
