You know for sure that *if* PADI says it, it has been proven.

PADI recommended the 60ft/min (18m/min) ascent speed. It has never been proven.

PADI also used to kneel on the bottom (like last year). That may indeed have been relevant in the era prior to the bcd. It's nice that PADI now starts to teach things like regulator recovery while hovering. Only with one decade latency. So no, PADI is not the voice of God :| It is a big company seeking to maximize profit.

Their student materials, however... WOW...... the words "stream of consciousness", and "rambling" come to mind. The words "structured", "clear" and "consistent" do not. Not even close.

Tom Mount is a specialist of spiritual healing or something like that :confused:. He is not a mathematician. But he has a point and his words are very worth reading. Once you helplessly look as your buddy slowly but unavoidably goes into panic, then hyperventilates and passes out, you start to appreciate the "mental things".
 
When I look at the PADI manuals with all those big colourfull drawings, I can't avoid the feeling that they treat me like a child. My school books were similar on ... third grade? The theory itself is ok. Nothing wrong with that. I just don't like the looks of it. Some people may claim that PADI is more "pedagogic", so I guess that style may suit many, but I absolutely hate repetition and quizzes and hand-holding litterate people. This is yet another proof of people beeing different and that you'll need to pick a book that you like personally. Diving at recreational level is no rocket science.
A student can be certified at age 10. The instructional materials have to work for all levels of students. You may prefer that this material, which you admit is not rocket science, be written at the rocket scientist level, but that will not be good for everyone.

That is 100% true.

And PADI sold me a book intended for a ten year old :D

Depends on what is meant by "proven." PADI says "no more than" 60 fpm, and that was the speed that was used for ascents when its affiliate, DSAT, tested the recreational dive planner. Given that the RDP has provided reliable results, one could say that 60 fpm is "proven" in the sense that it has been used and found to be reliable.

The current 30 fpm rate that is generally recommended hasn't been proven either. What has been proven is that it can produce smaller quantities of asymptomatic bubbling detected by Doppler equipment. The notion that smaller quantities of asymptomatic bubbling translates into less risk of DCS seems reasonable but is unproven.

On to PADI bashing: one complaint that I have about PADI is that sometimes the questions on their quizzes are defective. But that is a minor nit (and not really bashing).

And back to the OP: Whatever course manual you use, I recommend that you supplement it with The Certified Diver's Handbook by Clay Coleman. It covers most, if not all, of what is in the OW and AOW manuals and more. It is very well written.
 
I will most certainly agree with you on the fact that I don't have the numbers to back up my comment (AND) the fact that neither do you.

Opinions ... everybody has one and at the end of the day it dosent mean a dam thing either way. This is about learning material NOT about who has the biggest check book. Every sun deck on a dive boat, every bar at the resort, every SCUBA shop after hours party, every gathering of SCUBA divers you will ever rub elbows with always ends up at some point in a conversation about what fin is best or who has been deeper, down longer, and has the best mask, ect.ect. YOU WIN, P.A.D.I. is the most Bitchin, Coolest, Groovy bunch of super human people on Earth. Im going to change my will first thing in the morning and leave everything I own to P.A.D.I. But right now at this very moment my sides are still sore from laughing about the most profound statement I have ever read claiming they have certified more people then( ALL) the others combined. WOW They really are Super Human. They are amazing, actually I think (ALL) the others should just throw in the towel and give everything they own to P.A.D.I and be done with it. I never realized until now how incompetent the rest of us are. Ok well enough of this for now, I have to go send a check to P.A.D.I and bow down on my knees until the sun comes up in front of a P.A.D.I flag with my left hand on my heart while pledging my scouts honor.

Than? The old one? Other agencies?

This statement is much weaker in feel, content, meaning.....

<vbg>

Than the old style manuals. The new manual is a odd square shape, on very thin paper (you can see the text on the opposite side through it) and is in big print as if its addressed to hard of seeing people.

The manuals in quality WERE better than any other agency but this "new" OW one is definitely a lot cheaper to produce and feel (but obviously the cost is the same as before...)

In terms of terrible manuals, you cant beat the older TDI ones. Horrific black and white, dodgy images, lacking in info, full of errors. That said, their newer stuff is much better.
The SSI materials are OK now these days as well.

You are evidently unaware of the history of ascent rates. The 60 fpm rate was determined by the U.S. Navy long before PADI existed, and it was still the diving standard when PADI used it for the research that led to the RDP. Research after that supports a 30 fpm rate. PADI`s newest course work says no faster than 60 fpm, but it tells compter users to follow the algorithm of their computers.

Please name any major OW instructional agency that stopped teaching on the knees befoe PADI.
 
I was certified SDI and have SDI solo and PADI DM. Along the way I took specialty courses from SDI, PADI, and SSI. I frequently bought manuals for specialties and read them ahead of time. Later I might take the specialty from a different agency or not take the specialty at all. I have taken at lest 9 specialties plus Rescue. Sometimes I liked the PADI manual. I am reading PADI search and recovery at the moment and it seems informative. However, for Rescue I liked the SDI manual better than PADI. It seemed to me to have more content. Read both PADI and SDI DM Manuals.

I found the PADI DPV book not worth very much. However, the course was great. It was taught by an experienced cave diver and we got to try out a variety of DPVs from lightweight recreational ones to big long black cave torpedoes.

The solo course was also excellent again because of the different experienced instructor.
 
Ok So be it. I am breaking my own rule about even reading threads that start out with, Whats the best fins, or whats the best BC or whats the best tires for my car or whats the best oil for my tractor, ect...ect... I never fails, every forum regardless of topic has to hash out this stuff. I have been all over the world traveling to SCUBA related destinations and have met people that have been certified by agencies I haven't even herd of..... snip.....

I'm reading a lot of frustration and anger here but not much in the way of actual facts.

One thing I do agree with is that there is generally some "tension" between the needs of instructors to create skilled, competent divers who enjoy the sport and the needs of shops that need people to buy things in order to survive.

However, I, in no way, see a lack of common ground. For example, when I teach OW, I do (if I do say so myself) a good job of preparing people to dive safely and enjoy themselves. The LDS also gives me more than enough room to do this. I also push new students to become and to remain active. This is important for them, especially in the beginning, to get experience for their own safety and development, and also for the shop that will be more than willing to facilitate them by offering gear that suits their needs.

In other words, as an instructor, I don't sell gear. I never have. I make it clear to my students what options they have and I SELL becoming an active diver because this is what I believe in. It turns out that the shop I work for likes this approach because they can sell con-ed and stuff to divers. We also have a retention rate well above the industry baseline. Why? because people took a diving course because they thought it was going to be fun... and we make damned sure they're having fun. It's really that simple.

As for money; yes, at helicopter level money is important, but it isn't "all mighty" in the diving industry. What I see around me is that the diving industry is FULL to the brim of enthusiastic people who love this sport and are trying to make work out of their hobby. The reality is that they need to make a certain amount of money in order for them to continue doing what they love. But NOWHERE in the diving industry do I see anyone, at any level, thinking that making money is a goal in and unto itself.

I don't know what you do for work but I used to work in finance and believe me when I say that companies that see making money as their primary goal will not involve themselves in an industry with such thin margins. The real "money" people are all about swindling, deception, and even fraud, right from the lower executive level and up. If you spend much time with these managers, you'll also realize that there is something really wrong with them. It seems as though the finance industries attract sociopaths like flies to ****. Lots of good people work for things like banks and insurance companies but they work to support the greed of their executive. I think if many people who work at banks actually met and spent much time with their executives that they would probably quit out of fear of getting infected with the same disease. Personally, I'll never work in finance again because I don't believe that stealing from the poor and giving to the rich is right. That's real greed, and nothing even remotely like this happens in the diving industry....at all.

You seem to be seeing greed, but I would submit that what you're seeing is low-level panic, the panic of knowing that it will only take 1 or 2 bad seasons to make your business go tits-up. Some people do strange things because of that, but at its root, it's not cynical, it's fight or flight. The primal instinct to survive.

Second YOU stated that PADI was "no friggin way" the largest in scuba market share - YOU said it. So-Where's your proof? I cited what's out there- what data do you have that contradicts?

The numbers may lie but they would seem to suggest that PADI controls 75% of the recreational market. That would make them bigger in terms of numbers of certs in any case, than all of the other agencies combined.... and by quite a margin at that.

Being the biggest doesn't necessarily mean that you are the best, however. If you were to objectively compare PADI's OW course with the GUE or the scripps method then I don't think PADI would come out on top. However, they are probably the only recreational agency that makes good on their mission statement...."the way the world learns to dive".

PADI recommended the 60ft/min (18m/min) ascent speed. It has never been proven.

Let me qualify this. When the RDP was developed it was tested with a representative cross-section of people.... Old/young, thin/fat, fit/unfit. They used 18m/min as their ascent rate and during testing there were ZERO incidents of DCS.

It was real research, done by real scientists and it proved that this ascent rate was reasonable when using the tables.

I think what you meant to say is that it wasn't proven that 18m/min was the BEST ascent rate. I think that's probably true. But they did prove that it worked.

Tom Mount is a specialist of spiritual healing or something like that :confused:. He is not a mathematician. But he has a point and his words are very worth reading. Once you helplessly look as your buddy slowly but unavoidably goes into panic, then hyperventilates and passes out, you start to appreciate the "mental things".

I don't know him except for exchanging a few posts online over the years. I didn't want to give anyone the impression that the IANTD books are useless, but they're a dense and difficult read (at least the versions available when I did my training). Tom Mount may be an outstanding individual (I do get this impression) but as someone with a basic understanding of educational theory who makes his living "communicating", I can safely say that he should have hired an expert to write for him.
