iantd advanced nitrox vs. tdi advanced nitrox

[mannydib]

It's all about the instructor. Find yourself a good one, won't make a difference which card you get. The difference is all about the instructor....Good Luck...

NAUI, IANTD, and TDI all teach very similar courses for advanced nitrox.

You will learn the major formulas for technical nitrox, rather than using tables like you did in basic nitrox, and you will be qualified to use all nitrox mixes up to 100% oxygen as a deco or diving mix.

There will typically be 3 to 4 open water dives in your advanced nitrox class, and you may or may not sling a stage tank on one or all of the dives, depending on the instructor.

Ask your potential instructors what you will do in the course, and compare them. Then pick the instructor who gives you the most.

Another thing to be careful about is to see how highly qualified your technical instructor really is. The highest certification is as a cave diving instructor. The next highest certification is as an advanced trimix instructor.

Some instructors are only rated to teach basic norm-oxic trimix to 200 ft.

Some instructors are not yet rated to teach trimix at all.

Pick the instructor who is the most qualified from among your choices because he/she can then take you as far as you might want to go.

Manny, in my opinion they are both worse... look into GUE as they have the highest standards and teach a standardized curriculum.

just because the instructor teaches cave doesn't mean they are qualified to teach trimix classes.

all it meas is that they can teach OC cave..

in agencies that teach CCR rebreathers, the highest rating is a CCR-trimix instructor, cave is just a "specialty". There are cave instructors without equivalent advanced trimix ratings... It varies with the agency

CCR gas theory is much more advanced than OC gas theory, if done right..

If someone is teaching CCR trimix cave, now thats an advanced class... or an equivalent advanced wreck penetration class.. each has its own dangers just because you are an expert in one enviroment doesn't mean you are in the other..

advanced wreck exploration and Cave both have different skills and procedures that have to be learned..

Take whichever one you want...it really doesn't matter. IMHO, the advanced nitrox is beyond worthless unless you take a deco procedures class (or equivalent) also.

Are you really going to be doing that many shallow dives on >40% nitrox?

If you are going the deco route, then instructor choice gets really important really quickly. Choose wisely..

IANTD Adv. Nitrox certifies you to use up to 50% EAN, not O2. Technical nitrox is covered in trimix class.

Manny, in my opinion they are both (Editor's note: referring to both IANTD and TDI) worse (sic)... look into GUE as they have the highest standards and teach a standardized curriculum.

Really? Both?:wacko:

Here we have a classic example of the "shoot from the lip" style that so infuriates a lot of other divers when it comes to certain members of the GUE who can ABSOLUTELY be called
"cultists!":whack:

I said that he should look into GUE "as they have the highest standards and teach a standardized curriculum".

Which part of the above statement is false?

I don't see a falsehood personally, but can understand how that might piss other people off. From my experience with TDI and GUE (multiple classes from each), GUE's standards were much higher.
