IANTD quality and acceptance of their certs?

Madison is also pretty shallow.

I dove it on 1/6ths the first time I was there and raced out to not rack up deco.

I don't know anyone who has gone through full cave without at least advanced nitrox, most of them completed deco procedures either during or prior to full cave.

I never took either of these courses. We learned about deco in Open Water, and exactly what do you learn in "advanced" nitrox? My nitrox course was pretty thorough.

You know, Advanced Nitrox. The course that "Allows" you to use more than 40% nitrox.

To me it was more about getting O2 fills than being "allowed" to use O2. My local shop insisted on a card before filling O2. Their DSAT course was way too expensive and led down a training path that I did not want to go so I took the TDI course somewhere else.

I just went to a doctor friend who wrote me a prescription for oxygen - I went to the oxygen store and got a T-bottle, and fill my cylinders from that. I've been doing that since 1996.

I ran into the same problem, the LDS wanted an "Oxygen Provider" card. I thought for a couple minutes, and pulled out my pilot's license. I told them that all pilots had to know how to use O2

I did the Rec. Trimix course and use that as my training for Deco, I had wondered what particular training may or may not have been done for Deco in Cave, but being the new kid on the block, had kept my mouth shut. On the Aviator O2 thing, I gave up and just fill my aircraft O2 bottle off of a welding bottle, local morons can't get past the prescription thing. At least in Albany Ga., the source of ALL O2 is LOX, there is nothing different form medical and Aviator O2 or welding O2. It could be argued maybe that they bottles are cared for differently, but the source is the same. No "moisture" is added to the O2 for any O2, nor removed. I assume that liquefying O2 has a tendency to remove any moisture.

Exactly how backwards does that sound to a layman?

...the source of ALL O2 is LOX, there is nothing different form medical and Aviator O2 or welding O2. It could be argued maybe that they bottles are cared for differently, but the source is the same...

The only issue is when a welding O2 tank has been allowed to run almost empty, and then acetylene can get into it. Even worse would be if the torch flashed right about the same time, then there would be CO in it

Aviation O2 is safer, since nothing but O2 ever gets into the tanks.

I have never had to show a card for an oxygen or trimix fill, or even to get bottles from the supplier.



Okay, wait, that's not true. I have had to show my AmEx and MC...
