what do the standards say?

[bent]

Demonstrated clearly here, there is some freedom afforded in the use of the term, note in particular the loose term "an authority"

A dive certification is not a "permit from an authority" or a "official permission". I could start my own agency tomorrow, I call it "Bents Deep Diver Gang". I get myself a little C-Card printer and start to sell training... some agencies actually started out like this. Most of the people that started this way had more street cred than I though.
To be an authority you have to have power over something more than a printer. The NACD is basically a private club.
Slüdge said pretty much what is says in the quote you posted.

Okay, from a cave/trimix instructor point of view, taking an Intro student into LOG (whatever agency cert and whatever mix they're diving) is nothing short of moronic. Just my opinion as always...

Safe diving,

Rich

I would also add Hendleys to that statement

I'm with you on taking an Intro diver to Lower Orange Grove, Hendlys or the Nest. Doesn't make sense.

NAUI requires AN/Deco as pre-requisites for Cave 2 and as far as I can tell by reading the TDI Standards you can combine AN/Deco with Full Cave but all required dives from from standards have to be met.

There are some other Certs that can be combined with AN/Deco.

Tony,

I talked with TDI last week about this very issue. I have a student that is interested in progressing to full cave, and needed to complete AN/DP, and although DP is clearly stated as being allowed to be incorporated in full cave, there was no mention of AN, so I asked if they could be combined. Here is what they sent me:

Yes, you can also incorporate AN into a full cave program, I would suggest
conducting 4 dives specifically focusing on AN/DP components in addition to
the full cave course (crediting 2 dives from full cave to the AN/DP
portion). This is, of course, a minimum and if you feel additional dives
are needed, that is your discretion.

At the end of the day, the student and I opted to just focus on AN/DP at this time and we conducted all of the dives in what is essentially open-water (OG basin for skills development and then Hudson Grotto for the 130' dives). The student still owes me a skill before he's finished, which will be conducted in OW at some future point.

There are options...

So exactly what is learned in an "Advanced Nitrox" course?

When I took it my instructor took me on the Henleys jump but I had to stop and hold position at a certain depth. I dont recall what depth.

What a stupid question! You learn to breathe advanced nitrox!

Likely best answered by somebody who knows details but I think that course teaches you how to breath mixes that have 41% oxygen or higher as nitrox is only up to 40%.
Or maybe that is the point where they finally release the top secret "T" formula so you can figure out your MOD for yourself instead of using a chart! Lol.

The stuff everyone should have learned in a regular nitrox course, but probably didn't.
