adv. nitrox

[matt_unique]

Basically ditto from my experience. I chose to take TDI Deco Procedures first then Adv. Nitrox the following summer. Adv. Nitrox was nothing like the first Nitrox course. You can look at the TDI website for course details, gear, etc.

nautical adventures in cookson, ok. just 15-20 minutes away is sdi/tdi, but im not sure if there is a tdi instructor there. I would think there is since it is tdi. haven't really asked about it. just started looking into it.

advanced nitrox is esentally the equavalent to the open water class for tech divers
and yes is usually tought with deco.
depending on your instructor alot of extra stuff will be tossed in for skills not required my the certifing agency.. those are the instructors you want. because those skills keep you alive...

As everybody said - it's great but difficult course.
I did with IANTD, 4 days, a lot of lectures and minimum 2 dives every day.
Really loooong days.

I'm an IANTD advanced nitrox instructor and do basically the same program as Rick above. In IANTD it "qualifies" you to have up to 15 minutes of deco with a EAN 50 mix. Basically, it is an introductory "tech" class, teaching you fundamentals of deco diving, reels, lift bags, etc while stressing "spot on" technique issues like trim, neutral buoyancy. It can be taught with a single tank and stage bottle or with doubles, based on the instructor and the participants. It is a great course and one I would highly recommend to anyone, even if they don't plan on doing a lot of deco diving, because it will simply make you a better diver.

I agree with what has been said above.

I would add that if you are considering these classes I would suggest that you have already begun working with tech gear some time beforehand. In addition you should already have a basic knowlege of the skills, techniques and planning (math) that will be required in the course. 100% O2 is a tricky thing.

Working on your gear configuration in advanced will make it easer to soften the blow of both the learning curve and the astronomical expense in store for you.

Should you decide to go tech you have a great world in store for you.

But, the cash you gave to PADI (or whoever) was just a down payment on the diving jones you will have to feed.

Is the advanced nitrox class like the basic nitrox class. Does it require dives, or is it taught with other courses such as decompression?

It depends. I took ANDI CSU, which is an "advanced nitrox" course, but it taught everything up to, but not including deco. The course covered diving with two nitrox mixes (upt to 50%) and doing a gas switch, but the line was drawn at deco. Courses from other agencies vary. We learned a lot in the class, but we also learned a lot in the water, which for me is a key distinction between a basic nitrox course and an advanced nitrox course.

Just wondering,what is the point of doing a gas switch if you are not in deco? Is it just a super safety stop??

 

[PerroneFord]

You would do this if you were staging. This is also how it was used in my class. Basically we did 1/3 of the dive on backgas, switched to the stage which gave us the idea of storing the long hose, deploying the stage, etc. Then we switched back to backgas for the ascent. It was a good learning experience.

Good question. Finishing a dive on 50% could be considered a "super safety stop". When I carry a 40 cf sling, I usually use it as a stage to extend my dive when I'm diving with one of my buddies who's using doubles, but occasionally, I use it for redundancy on a deep dive. If the dive site lends itself to a multilevel dive, usually I have 40% or 50% in the sling so I gas switch when we ascend at the end of the dive - always planned in advance. I'm sure that makes anti-pony zealots cringe, but frankly, I don't care. I like diving with a sling and when I get to the point where I need it for deco, I'll be well-versed to using it properly.
