I recently contacted my LDS Owner (from a PADI shop, though he was just certified as an SDI/TDI instructor) and told him I would be in the shop in a couple of days to pick up a Nitrox book for something to do in the off-season, being PADI certified, I assumed I would pick up their version. He stated that he would order me a TDI Nitrox book as he believed it would be more valuable. My question is simply, what are the major differences in TDI's teaching of Nitrox, and PADI's teaching. I understand the differences in recreational and technical. But don't understand how there could be a large difference between the two. Are the formula's the same?
Now, I have not taken a nitrox class, and I am not by far a tech. diver, but I do enjoy math, and I have browsed the Boards long enough to understand the theory and usage of nitrox, so please keep the terminology simple.
Thanks!
On a side note: I am looking to becoming a DM in the near future...not a zero to hero kind. (I need way more dives). Is there major differences between PADI and SDI/TDI DM's, or as a DM does it not really matter what your certifying agency is.
