Diving myths taught for safety?

[swimmer_spe]

Good question - PADI doesn't anymore.

Reviewing my son's PADI OW Manual from 2010 - in Chapter One - page 59 - the following direction is given to setting up your tank: "While holding the SPG away from you, open the valve all the way gently."

Likewise - in my PADI DM slate (2011 version) - Predive Safety Check - The following direction is given during the check: "Valve turned on all the way?"

Maybe someone from the other agencies will chime in too.

Cheers,


Bjorn

My PADI 2007 version has the same thing, on the same page.

ACUC about 3 years ago: open all the way.
SSI about 6 years ago: used to teach the quarter turn back, but they had changed it to open all the way.

So, it sounds like we found a true myth!

Valve fully open is now the rule.

Lets be realistic, 3 simple courses would suffice: Open water, Overhead, and Deep. Name me a real skill that could not be covered in one of those? Caves and wrecks? What do you think is.. overhead? Dive deeper than the no deco limit, thats the deep dive.

Well, here goes as I see it.
1) Overhead is also ANYTHING that prevents you from a direct ascent to the surface...i.e. deco. Overhead does not teach you deco. If you are refering to UTD it is not for deco which is an overhead enviroment.
2) exactly how do you get to, "Dive deeper than the no deco limit," without Nitrox, AOW, Ad. Nitrox and Decompression?

1) Exactly. if you are confined then it is an overhead environment.

2)Nitrox would make sense for the deep part.

The more courses there is the more the various organizations make. Where as, the fewer courses there are, but the more indepth they are, the better the diver will be.

So let me get this right.....you feel that a more "In depth" course at the basic level will make someone a better diver ? The only problem with that thought is.....it used to be that way a longgggggggg time ago but then $$$$$$$$$ got in the way and as you noticed the Certification Organizations realized they could make more money by watering down the courses and "Marketing" all sorts of courses to people like "Zombie Apocalypse Diver" "Reef Fish I.D. Diver" "Boat Diver" "Dive propulsion diver" "Digital Underwater Photo" etc. etc..

My Basic class was 12 weeks twice a week my advanced class (after about 75 dives) was another 12 weeks twice a week each one of these sessions was about 3 hours with 1 1/2 in pool and 1 1/2 classroom = about 36 hours per course.You have to ask how much would an instructor charge for that now and how many people would be willing to pay it and make that type of time commitment.

After my Advanced course I also received a YMCA S.L.A.M. card which is/was equiviliant to the Padi rescue diver.We all received both Padi and YMCA certifications

I am glad I was initially certified when I was (almost 40 years ago).If you ask some of the divers who were certified then I am sure you will see that many received the same amount of training.

Yes I am a dinosaur.

Watered down courses are better?

Maybe you didn't get the implied sarcasm in reference to watered down courses.

How does one find their limit without hitting it? However, I am not going to do anything I know will kill me.

Sometimes what you dont know IS what will kill you. A lot of those "Myths" are there for a reason.

Yeah, if you know what is going to kill you, you will choose to stay out of it's way. I do.
