SDI/TDI Prerequisites?

[scadreau]

I have clicked through the website but cannot find prereqs for any of the courses.

In particular, I was looking for the prereqs for the Tech course circuit. (Adv N, Deco, Ext Range, Trimix and Adv Trimix)

TIA,

Scott

You can work backwords - either Trimix or Extended Range is the prereq for Advanced Trimix. The two courses are essentially the same, one just has added Helium.

Both Advanced Nitrox and Decompression Procedures are required for ER and Trimix.

You can do Decompression Procedures with any AOW style certification, you do not need to do Advanced Nitrox. But the course is limited in the gasses you can use if only qualified to dive air or recreational nitrox.

Advanced Nitrox has a prereq of basic Nitrox.
