PADI Deep Diver Standards

Mad Dog then says, “there’s four ports and four of us, drop ‘em,” and proceeds to drop his pants about his ankles and paste his hams onto one of the ports. I was amazed as the State Policemen and the O/W U/W Scholar followed suit and then, more to not be left out than as a result of intoxication, I did the same.

This would make a good picture for your avatar. :blinking:

Well, Thalassamania, none of the four of us went quite that far although that's quite an image. The chamber I was in had a camera inside it: I still haven't seen the footage. {edit: probably a good thing}

Part of the purpose of this chamber ride was to compare the functions of 6 different brands of computers placed in two buckets of water. I spent the entire ride from about 90 feet to 200 madly scribbling the results of the computers at 10 ft increments. Suprisingly, when I read my notes afterwards, my handwriting (which is usually illegible) became progressively tiny as the depth increased, right down to micro size at 200ft, yet legible.

It was on the way back up that I noticed I was still narced at 90 ft. That was the eyeopener.

The one thing the chamber made me learn was just how dense air is at depths of 40m+.

Moving your arm around you felt considerable resistance, talking you were squeaky. Breathing you could feel it.

Previously id been at that depth and just assumed my reg wasnt ideal for breathing air at that depth. The chamber made me realise its not my reg, its just air gets very dense at those depths making it harder to breathe and more effort (so more CO2 so increased narcosis and so on).

That's a well known phenomena, the paper and pencil compress.

But wouldn't the writing then expand as pressure decreased making it now a giant font?

No Diving without Snorkel................lol

So what I get from this is that a 12 dive diver shouldn't be taking a course that offers them more experience at a greater depth under Inst. supervision.

I guess they should wait till after their first vacation trip after OW where the DM says "Ok folks here we are at the abc site, the reef starts at 40 ft bottom is 125 ft the boat leaves in 1 hour 30 min be back if you want a ride to the dock".
Then when they get home take the class after they have more experience.

I know these dives and divers happen I did it everyday.

Doing and getting away with, even repeatly doesn't make it a good idea.

The problem isn't in doing them. Anyone can do a 300' trimix dive. Most of the time, everybody comes back. The problem is when things start going wrong. Then, you find out how much you'd like to have good quality training and expierence. The upside for most is things almost always work perfectly.

Even good instructors get narced.

You are right Jim. There should be an experience portion of the class. However, I do feel that taking students to the maximum depth of the cert on a training dive is not a good idea. Most tech training standards will not allow the instructor to take a student to the maximum depth. TDI Trimix course for example says the maximum depth for class isn't to exceed 180 feet, but it certifies the student to 200 feet.

Strange but we did 200ft for my trimix class.

Say, is there a breeze in here?
