..the 130' limit was before triox, so maybe they are reworking some of the standards and procedures since, IMHO, it doesn't make sense to have triox at 120' and then tech 1 at 130'. Then again, triox doesn't teach deco...who knows?

Our final dive of Tech 1 was to 165'.
The card we received from GUE says, among other things:
Tri-Ox (150ft)
Shane and I dive to 165'.

Once again the DIR crowd has taken over a thread. The original questions posted by cadet diver have nothing to do with what DIR considers to be acceptable depth limits for their Tech 1 class.
Cadet diver asked if:
1. A dive to 200 fsw for 15 min. on 21/35 with a single deco gas of 50/50 has been common for anyone else on the board.
2. If anyone has had problems getting appropriate sized stage bottles in the Bahamas.
The first question was answered well in that the depth/time seem about right and the use of just 50/50 may be preferable to 80/20 or O2 if only one deco bottle is available. Also that 21/35 may be a little hot, but fits within TDI guidlines and has been done by others on the board.
No one has given any info regarding the second question.
While I have nothing against DIR and those whose choose to adhere strictly to DIR principles, I do have a problem when every post on this board turns into a DIR discussion.

While I am truly sorry for the distress this has caused you... it is quite common for threads to meander off of the original topic, especially after several pages... and since we have quite a few folks on this board who are interested in DIR that topic does come up in a lot of threads. I think you will find that accepting that fact will go a long ways to relieving your angst.
BTW.... if you have an answer for #2 please feel free to contribute.
No I do not have an answer to question #2. I'm going on the trip with cadet diver.

The answer is that you'll probably have trouble getting 40s but 80s will be available pretty much anywhere. To some extent this will depend on exactly where you'll be. There may be a few places where 40s are available.

I kindof meandered the thread because the question of what the "acceptable" mix was for a normoxic cert diver. It had nothing to do with DIR, nor did any of the responses. The depth question was, again, in response to mix content and was actually directed at a shop owner for his input.
I didn't even notice the part about the tanks.
BTW, you might want to get a rather thick wetsuit to protect that fragile skin of yours. And no, I am not "DIR", but thanks for asking...

I wondered as much... are you also a cadet? What kind of cadets if so?
Ahh, you're good...you're really good :mean:
OP
I just want to say that I think you guys answered my question and I appreciate the help. I don't care if people are DIR or not, whatever floats your boat.
