    You need to seek SDI guidance on what they would accept. The BSAC equivalence table lists what BSAC accepts to do a BSAC course.

    You’d mostly need to do the Advanced Adventurer thing, and Rescue. Also TDI Deco Procedures, but nobody really does that without Advanced Nitrox and those two are quite an intense course. It really depends on what diving you want to do now, pretty fishes then the Advanced and Rescue, stuff like you used to do then TDI AN/DP is the current fashion for that.

    contact head quarters (sdi) they will set you straight , or just look up centers or instructors in your area then interview them before deciding

    Is the TDI advanced nitrox course normally the same price as SDI nitrox? I was just quoted 175 for one and 500 for the TDI advanced which was a bit of a shock though I do think the later requires a couple dives. I am beginning to question some prices at my LDS the sound quite high.

    If you're looking for the TDI "basic" nitrox course, that would just be TDI Nitrox.

    Advanced Nitrox is for mixes 50% and higher. Pretty much for deco. It's often combined with Deco Procedures into one course.

    The basic TDI Nitrox course is for mixes up to 40%.

    I I may have gotten confused about these after rereading. I recalled this thread and thought TDI Nitrox was the more in depth which I was is what was stated. I think I dot TDI advance Nitrox and TDI Nitrox confused and asked the advance price. Not planning deco so no need there. But if a course for the same price offers more in depth training I would prefer it. I need to rephrase what I wanted to the LDS, TDI Nitrox vs SDI Nitrox. Now If they say the price is 500 and 175 respectively something will seem off.

    Both the SDI and TDI Nitrox courses are for recreational divers, nitrox up to 40%.

    SDI Nitrox is the basic recreational diver course, pretty much "computer nitrox."

    TDI Nitrox is for recreational divers, but has the math, while the SDI NItrox course does not.

    So, if you want a recreational nitrox course with the math, you want the TDI Nitrox course.

    ETA: At my LDS, the SDI and TDI basic nitrox courses are the same price. TDI Adv Nitrox is $400.
