I breathe underwater without "oxygen tanks" all the time. Been doing it
for years.

You're gonna have to qualify that statement with the infamouse Clinton quote
"I did not inhale". Unless of course, being a PADI instructor, you've been
under water for millions of hours that you've developed gills.

Hardly. You can't even get a regulator onto an oxygen tank without modifying
the valve or replacing it with an air tank regulator and it would be hard to
get filled with air.

Some of us PADI instructors were around when such things were done and
remember melting the lead out of the over pressure valve.
Even today if the subject of older used equipment comes up in this area I'll
warn to check for it.

(My first tank was a CO2 tank with a modified O2 valve.)

Heck, I've got a regulator on my oxygen tank right now. OK, my oxygen tank
is an 80 cf Luxfer, but it does have a regulator on it. Why in the world
would I want to fill my O2 tank with air?

Maybe so, but you weren't a PADI anything back then. I started diving
before PADI was a gleam in its founder's eye. As I recall, so have you.

I probably wouldn't but it would be more likley than going diving with the
oxygen tank that started this.

Yes, but I switched from being a NAUI instructor in 1989.

I went from YMCA to NAUI to SSI. Way back, when PADI first became popular
here, I knew a PADI certified diver who consistently put his tank in the
harness backwards and needed help attaching his regulator. The issue of
certifying unqualified divers is not new and it's been a valid criticism of
PADI from the beginning. These days, it's easy to say that there are more
bad PADI divers because there are more PADI divers, but back then, the
numbers were the other way around and there still appeared to be more bad
PADI divers than were coming from the other popular agencies.

I know a lot of good PADI divers and several good PADI instructors. In my
opinion, however, they are good in spite of PADI's corporate culture, not
because of it. YMMV.

Somebody who never learns should never have passed.
I've only refused to certify a few people. They went to one of the local
NAUI instructors and got their cards.
Most people I just keep working with until they figure out they may not
really want to dive.

I had a Navy SEAL in a class. Or so he said. He just wanted to be certified
so he could buy air outside the area....

Now I have shamelessly stolen a technique that guarantees most students will
get the tank, backpack, regulator thing right the first time about 99.9% of
the time.
But the SEAL fooled me. He put the tank in the pack rotated 90 degrees so
the regulator stuck out to the side...

Somebody once asked me about how to do that when they could not see what
they were doing. I forget why. My answer was, the hold the air comes out
of points at your head. It's the only sure way I know to get it right. In
the day, in the night, anytime at all, you can always tell where the hole
the air comes out of is. The direction of the valve handle used to be a
good way, at least until I met somebody that separated his manifolded tanks.
The left post, of course, sticks out the opposite side.

I currently have a friend who is a very competent rescue diver somewhere up
north who has absolutely no buoyancy or trim skills at all. He spend his
entire diving life walking on the bottom, a technique that probably works
fine where he is, but ensures you spend your dive knee deep in soft mud down
here and is the most certain way I know to ensure you don't get within
spearing distance of any fish.

oxygen tanks? how deep do you dive?

The correct answer should be "I don't know, whenever my gauge shows 33 feet,
I wake up on shore?"
