That's SO helpful, thank you! I'll definitely modify my schedules (and my diving style) to be more trendy like you. Let's see, lower PO2 and higher He at intermediate stops by using bottom mix, better for you - I think I've got it! It's so simple and obvious!

learning how to dive on the internet is a bitch.
 
maybe they came up with a cool mnemonic and needed an "n"

They were probably going out of their way to avoid "BOTOX" and this is the best they could come up with!

I believe ageddiver was one of the guys that dove the Portland this year. I would hardly classify him as an internet diver, but that's just me.

Just you.
 
Bob Foster aka ageddiver and team did a great job on that 08' Portland expedition......a very rare opportunity of adventure.

Thats nice.

Doesn't have any bearing on his current knowledge of decompression though. (ergo the "thats so 90's comment")

But you knew that didn't you?
 
That is a ridiculous comment. Unless you have intimate knowledge of the plans for those dives AND are doing those dives yourself with better and safer results you really don't have a leg to stand on, do you?

LOL..You have a serious reading comprehension problem.

I have his comments in this thread. The ones we wanted clarification for.

LOL Too Rich.
 
Interested in understanding and comparing pros and cons of the gas switching protocols taught by various agencies.

DSAT teaches the NO TOX mnemonic:
N - Name - Is this my tank?
O - Observe the MOD marking and current depth - can I breath this mix?
T- Turn on the valve
O - Orient the regulator - ie deploy reg/hose make ready to exchange
X - Exchange and examine - switch regs and examine your team mates to ensure they are breathing a correct mix

What are others teaching?

You've got the N and the O wrong:

"N" = note marked mix/MOD
"O" = observe actual depth

There is no "Name/Is this My Tank?"
