padi diver to ccr diver!!!

cameron

my girl wants a kiss, but she dosn't want to go through the bullshit and equipment investment to get the "advanced nitrox" card, you know, doubles and all that. I know for a fact that she has NO interest in deep diving and deco but wants lots of bottom time. She has a very good understanding of the theory behind diving, so class room stuff isn't going to be a problem. So the question is, how can she get her trainning done? Are there ways around the requirments, or is she stuck in doubles to get the stupid card??

Does Naui have a Kiss course? I got certified on my Prism with basic nitrox as the only prerequsite. If they have a Kiss course, it should be the same.

The adavnced EANX can be done in conjunction with the CCR diver training and there is no need to buy any additional OC gear other than stages it can all be done on a breather.

ANDI's CSU (nitrox) class will do for NAUI and ANDI CCR user training.
The resulting certifications are for air dil, no deco diving within rec depth limits.
And ANDI is finishing up the textbook for KISS training.

Or as Chris said, many instructors/agencies offer a combination of the two classes.
Personally I think it's easier getting through CCR theory and math if you have the
nitrox stuff down, but it should be managable. Especially if you're prepped for the class.

You can do the IANTD deeper diver course in conjunction with the KISS CCR course.
But let me tell you one thing...
If you think that Adv. Nitrox course is bullshit, then i believe that you are getting yourself into troubles. I understand that you might not want to purchase alot of extra OC stuff. the sling you will need anyhow, so there comes an extra reg as well.
But if you dont get the theory behind pressures, mixes, decompression. Hazards of O2 etc etc etc you could cause alot of problems for yourself and people around you.

Hello caveseeker, all. I can imagine some reasons why advanced nitrox would be good to have as a prerequisite for recreational Rebreather, but is it really necessary for plain old recreational no stop CCR diving? Do you have to have advanced nitrox for operating an O2 CCR? Other than understanding your mod and the concepts of cns and otu's, how much training do you need to operate something as simple as an O2 CCR? Don't get me wrong, I enjoy learning things. But the logistics of training can be very difficult and expensive. I don't mean to sound like such a sceptic...Andy

Well Andy let me answer a few things for you there...
in a CCR you are using one diluent bottle, which contains some kind of breathing air.
It can be:
normal air. 21%O2 and 70%N2
high mix
or low mix
and any kind of helium mix
These are tought to you in Adv. Nitrox course and not in basic nitrox

Also you will have one O2 bottle... this bottle contains 100% pure O2. Well medOx which i use contains about 99.9995% i believe it is... correct me if i am wrong. But anyhow you need to know how to deal with high pressure O2. And that is tought in Adv Nitrox. Basic Nitrox certifies you to use High persentage oxygen mixes in a tank up to 40%

Then there are some tables, dive planning, bailout planing... etc etc i am not going to run through the whole thing right now. And i do not really remember all the things that was in the course. But i believe it is vital for your safety.

Hi,

I am lead to believe that it is possible, though uncommon, to do the Advanced Nitrox course without a twinset, ie single and stage. So, that being the case there is a minimal outlay for equipment.

Personally, I would suggest that the Adv. Nitrox training is essential before operating a breather due to the equipment, physiology, task loading etc and just getting your head round the whole thing. It really does take a while. Thats probably why its a pre-requisite..!!

Without wishing to hype it up, a move from no-stop recreational air diving with a single cylinder to mixed gas CCR is a BIG step, not to be under-estimated. About the only bit that is the same is the breathing bit.

...on the other hand, if you follow all the rules taught on MOD1, does it actually make any difference knowing about MODS, %'s etc when you are in the water? (For non-deco, air dil, simplistic stuff).

You'd need to know why you can't breathe O2 > 6m but from a purely operational side, as long as you follow the rules, where's the problem?

Just make sure the girlfriend isn't feeling pushed into something to keep up with you... Training usually helps...

Personally, I think basic skills like bouyancy control are more important than having muscled twins.
Why require deco and than tell people you are not allowed to do deco dives.
Sorry, but that's when my BS alarm goes off.

Either require deco and then do and certify for it during CCR training or bugger off.

Adv Nitrox and O2 CCR? I don't know, I don't have either.

Took ANDI's CSU class to fill the CCR requirement:
"May use Nitrox mixtures of 22% to 50% to 40m/132fsw performing
No-Decompression-Required profiles with 2 cylinders and 2 gases.
Depth limited to gas mix and OW diver certification limit."

That's straight from the card. I thought it would be a good class as a primer
for rebreather as mixes went to 50% and it included the use of a stage.
Which was provided by the shop/instructor I did the class with.

As I said before, materials and classes were very good. I learned a thing or two I didn't know.
And I didn't have to haul around twins to take it, much less buy any of that junk.
Said it before and say it again: If I need twin cylinders, there better be a rebreather in between.
