wheelietaco:I guess i should have made it clear. it was ow cert that gave me tables. i am just looking for which agency to take it with. I like tables. i also use a computer that is nitrox compatable. i was going to take it through SDI and i would just like to be able to get the tables to.
I've got basic nitrox through TDI, the tech arm of SDI. I'm assuming you mean you wish to take the TDI course because I don't think SDI has a separate nitrox class. The TDI crew pack comes with a table. It's better than the PADI tables in some ways. One side has EAD for air table depths 30-140 feet for all mixes 21-40% in one percent increments. This side also has the MOD for PO2 of 1.4 and 1.6 at each of these O2 mixes. The other side of the table has the PO2 time limits for the same mixes, 21-40% in one percent increments, for desired max PO2 exposure from 1.0-1.6 in 0.1 increments. Very concise and handy. The drawback is that it's not the thicker, rigid style of slate, but a thinner, flexible coated plastic.
