Choosing Between Various Nitrox Classes

[Dive Hawk]

I must admit that I have never heard of or seen anything about a PADI "Discover" Enriched Air Nitrox class. Is there really such a thing?

I don't believe there is such a thing. I just did the PADI EANx Diver class a few days ago, and I don't remember anyone mentioning a "Discover Nitrox" class.

PADI's EANx Diver allows you to use enriched air up to 40%. It seems stupid that SSI would make you take two classes just for Enriched Air... It's really pretty simple stuff...

It seems ridiculous that an agency would see fit to split courses up based on 22-32% and 33-40%. It has to be solely a money issue, because it is really an unnecessary additional layer.

Teaching students to just follow a preset composition of gas seems completely ridiculous, too. I am just glad that I am "allowed" figure out my own best mixes and where available get fills that can utilize them. If I were you I would look for a different course, perhaps like the SDI course that was recommended by H2O 70.

Which courses teach following preset compositions of gas? The PADI course I took taught you how to figure out which mixes of gas would work in/for certain situations from 22% to 40%. It's just that the two most common types of EANx are EANx32 and EANx36.

Are we on the same page here, or am I way off base? :cool2:

I just took the SSI, no option of levels, covered 32 and 36 and the tables. Basically, analyze the gas or witness it, and plug it into your computer. And understand the dangers and the limits.

Hi,

SSI decided some time ago to split the EAN course into 2 - Level 1 up to 32% and Level 2 up to 40% oxygen (about the same as PADI is doing with Discover Enriched Air and Enriched Air). So either the SSI EAN Level 2 or the PADI EAN is what you want to go for. Both SSI and PADI do offer advanced Nitrox clases as mentioned, SSI as part of their TXR programm, PADI with the TecRec.

I took the claimed SSI split to be more of teaching to presets. What is the real difference between the ranges of gases, not that much if you already know how to calculate the MOD, EAD, etc, etc. Since they teach up to 32% then have another course for the upper range <40%. HOWEVER, I just looked at the SSI page and don't see any split for EAN training, so I dont know if the original claim is true or not.

Sorry if I confused anyone :-/

seriously? Is it too late to get your money back?

No need. Covered Nitrox diving fine. Did tables for 32 and 36, and the book and the class covers mods and and things thoroughly.

So no formulas or anything like that covered?

...Yeah, I was just thinking that same thing. They only covered the 32 and 36 tables?

Covered all the tables and converting from air tables, it was fine. Would have liked more time with the analyzer, but I an comfortable with the training.

So you did not just work with 32 and 36 tables? Did you learn the formulas behind the tables? Personally I never got tables in my nitrox class (other than air tables).
