What are 32 and 36% if not standard gasses?Scuba_Steve:So much for teaching standard gases, and an easy to use EAD formula so you can use your air table you already know anyway........
Yes I know the look well. I get it every time I teach a tech class to a PADI nitrox diver. I usually have to spend and extra hour getting them up to speed. I teach PADI, ANDI and TDI but have never taught a PADI nitrox course because I don't believe it adequately covers the subject.Mothball:BC, I took the PADI EANx course about 4 years ago and they taught me to use the 32% & 36% tables, an EAD table and CNS % clock table along with the formulas for EADs, MOD & contingency depth, O2PP @ depth. After my girlfriend took the class last year I immediately noticed that glassy eyed look on her face when I talked with her about EANx. I finally figured out last month that PADI no longer teaches the formulas, but only the tables (32% &36%, EAD, O2PP) to basic EANx students. I was told that the course I took was more like an "instructor" level course :icon5: :icon5: :icon5: Since I took my course I have read manuals from IANTD, TDI, PADI TecRec and Trimix and have furthered my knowledge (especially in the math department) which further disgusted me about her "laziness" to apply her knowledge of EANx. I just didn't realize that laziness was not the problem, they did not teach her, a problem that I have now fixed. The tables are, in fact, adequate, but...:icorolley :icorolley :icorolley Semper Fi Dave
I suspect that the level of detail in the PADI course depends on the quality of the instructor. I took the class in March this year. It included the use of 32 and 36 percent tables, an EAD table and an oxygen exposure table. We also covered the formulas to calculate everything except oxygen exposure without needing a table. The test required us to use the formulas as well.Mothball:BC, I took the PADI EANx course about 4 years ago and they taught me to use the 32% & 36% tables, an EAD table and CNS % clock table along with the formulas for EADs, MOD & contingency depth, O2PP @ depth.

beezwax:You can buy the IANTD tables separately (all the nitrox mixes, trimix, etc). Check them out at:

I'll let ya know later next week, after I take the TDI course I just paid for.Scuba_Steve:So much for teaching standard gases, and an easy to use EAD formula so you can use your air table you already know anyway........
Dive planning made seriously simple, and no hand-helds, 6 flip-charts on a key-ring etc.........
Sad to see niether TDI nor Padi by standard yet teaches this
