Nitrox vs. advanced Nitrox

[Gaucho]

Are these one course or certification level with different names or are they fundamentally different?

Basic Nitrox certifies you to dive with EAN mixtures to 40% (Typical mixes are EAN32 and 36, 32% O2 and 36% O2 respectively, where normal air is 21%))

Advanced typically takes you to gas mixes with greater than 40% oxygen. And this course would eventually lead you to mixed gas diving where during the dive, you would be changing gas mixtures, especially during deco. As an example, 100% oxygen can be safely breathed at a 20 fsw and this would greatly increase the off gassing of nitrogen.

Looks like TexasMike answered the question for you. And he is absolutely right. The average recreational diver won't use the skills/theory that's taught in Advanced Nitrox. Typically it's the tech diver or aspiring tech diver that would take this course right before either an extended range course, or a entry level trimix course.


Sea you in the Deep Blue!

 

[TexasMike]

Hey! I actually got one correct!

 

[Gaucho]

Thanks for the clarification. This considered, Nitrox is all Im interested in...

 

[Vettster]

I gotta ask.
Who offers the advanced nitrox course?

 

[Warhammer]

IANTD does and I'm sure there are others. Here are some other tech agencies. I don't know if they offer it or not, but you can look and see if your interested.

ANDI
NACD
NSS-CDS
PSA

 

[DiverDave]

TDI also offer this course.

These are two completely different types of courses. Nitrox is simply a class that teaches you to dive with an air mix of more than 20.9% oxygen. Advanced open water in SSI (SCUBA Schools International) consists of four specialty courses. Nitrox is one of these courses. In SSI you can take each specialty course at leisure and recieve a card for each. Then, once you have four of them, we issue you your advanced open water diver card.

Are these one course or certification level with different names or are they fundamentally different?

how exactly is advanced nitrox like advanced open water? advanced nitrox is obviously a beginners tec course...
