Dang, I nearly missed these.......wow!
Imagine being narc'ed and donating gas with this setup (focus on the bottle trapping the hose)

wow impressive, I am especially happy to see good trim, buoyancy, and buddy awareness emphasized along with depth, time and air.
that's right right up there with this one:

And I thought TDS was entertaining. Thanks, Tortuga! This is a riot.
Tough crowd..
Gary was my Normoxic Trimix instructor. While I believe he has a great deal of knowledge he is also living in the past. After class I learned a lot of what he taught was very out dated. I also do not understand how he could condone such high PP O2 as he does not use or teach O2 for deco because of the high PP?
OP
Wow, what a nice bunch of opened-minded, considerate, friendly people we have here in this thread
On the last dive - which is the only ****ing one that anyone wants to talk about apparently - we each carried 2 6l stage bottles, one with 50% and one with 100%
We had decompression hangs at 6m on 100% O2 lasting from 5 to 12 minutes, depending on the depth, so going to the surface would be a great way to get bent. As above, we carried our own deco gas. PSAI call it a safety bottle, go argue with them
You would put 100% O2 deeper than 6m? Interesting. We don't get "low or out of gas" because we have a minimum turn pressure of at least 100 bar on double tanks
The run-time for the 73m dive was 36 minutes BTW. The shallower dives had bottom times of 15-20 minutes. There were skills throughout the dive, information was recorded on a slate... Of course if you read the thread you would know this already

FYI with a 7' primary hose, you route it under the stage bottle, just like in the photo
FYI part of the course dive plan is doing an s-drill donation at 1m prior to the descent, so it was working just fine
Yes, it is impressive buddy awareness isn't it? The photo shows Simon So from LBC doing a 360 degree buddy check on me prior to the descent, making sure I don't have any leaks, that my hoses are routed correctly etc etc. This is part of the course dive plan too, and is done in vertical trim
Yeah, stupid me thinking I could make a thread about deep air without every moron on SB jumping on the bandwagon. You should be proud of yourself, you're the biggest one with your assumptions about people you know nothing about, your open mind, your friendly nature. You're only here to insult people, get bent and I mean that literally
Tortuga, I'm glad you took a class you enjoyed, and that you felt you got value from.
It is not a class I would take, or that I would recommend. And although some of the responses you have gotten have fallen far short of tactful, I believe the people are raising some very legitimate issues about the relevance of such a class in the day of trimix diving. You have perhaps learned some useful things about diving in very limited circumstances while significantly impaired, but there is no need to BE that impaired on a deep dive any more. In fact, cost and availability are the only arguments, really, for diving to 200 feet on air, and folks have observed (perhaps with excessive acerbity) that using cost as a determinant for your strategy for very deep diving is something which is generally regarded as unwise.
Your class, and your equipment configuration, are unusual in today's (at least US) technical diving, and nobody has a lot of enthusiasm for it. If you keep an open mind and think through the comments, and still make the decision to dive the way you are doing, you have every right to do that. We all make risk assessments in this sport, and all I ask is that people make them with enough good information to make the decision, even if it isn't MY decision.

Thanks for your well-worded thoughtful post. As always you are the voice of reason and politeness TS&M. Many people could, and indeed have, learned a lot from you here
Cost had nothing to do with taking the course, and the intention of both the course and myself is not to go out and replicate the course dives, a I mentioned earlier. "Why do it then?" everyone yells. To learn to manage narcosis, hence the name of the course. You don't have to agree
I made this thread because I thought people would be interested to hear some details of the course. Personally as I've said I enjoyed the course and found it worthwhile, but it's up to other people to decide for themselves if they want to take it or not. Hopefully after reading this thread they can make that decision more easily.
Naturally I expected to get bashed, but the attitude of several posters has been most disappointing to me, and not in line with the usual friendly open nature of this board
I also think people are focussing too much on level 6, there are levels 1-5 as well, in fact as I said that's the 'real' course, level 6 is an extra for those who choose to do it
