Normoxic trimix

Like I say check with an instructor but it certainly used to be the case that provided you had 'A' decompression qualification, 'A' Nitrox qualification and proof of experience diving in a suitable depth range, you could enter IANTD Normoxic at the instructors discretion. In a similar manner you could go from BSAC Basic to IANTD Technical provided you held a decompression qualification (Dports Diver or better). It is while since I had any interest in this so maybe the nanny state has caught up with them.

BUT......................

Can you do a normoxic trimix course having completed Adv' nitrox or do you still need to have done an ERD.

Speak to Mark Powell, he is both a BSAC tech instructor and TDI instructor.

SOrt of but dont forget you need decompresion procedures as well.

So the entry level for Normoxic Trimix is

TDI Advanced Nitrox

TDI Deco Procedures.

OR, IANTD Tech Nx - 2 TDI courses for the price of 1!

GUE Tech 1 ;]

Using the term ERD is confusing as the BSAC and TDI courses of the same name are not equivalent.

BSAC ERD is considered equivalent to TDI Deco Procs.

So to do a TDI or BSAC Normoxic Trimix course you would need

BSAC Adv Nitrox and BSAC ERD

or

TDI Adv Nitrox and TDI Deco Procedures

For someone with just an Adv Nitrox cert it is possible to combine the ERD/Deco course with the Trimix course but obviously this extends the course.

I am not an instructor! - just trying to highlight another option...

You are right that IANTD Tech Nitrox is equivalent to either the TDI or BSAC routes.

However, I'm not sure about your 2 courses from the price of 1. My experience is that IANTD Tech Nitrox is often only slightly cheaper, if at all, than a combined Advanced Nitrox and Deco Procedures course.

So you could say that it's 1 course for the price of 2

But of course I wouldn't recommend choosing a tech course based on price alone.
