PADI has been so successful precisely because their standards are so low.
PADI has been successful, because they have paid attention to the market and adjusted the program to fit what a typical consumer is looking for. The quasi-military Instructor attitude started slowing down in the early 80's, when PADI eliminated some of the 1/4 mile swims in the beginning class and focused more on training Joe the plumber to dive, instead of teaching him to become a lifeguard.
I also see skindiving as a lot of fun, but some people don't get it. That's OK, the skindiving in the past isn't what is being promoted now, so those people don't drop out of the class because they can't do something they don't see as relevent toward scuba diving.
PADI's entire marketing scheme was to take a course name that was in use (and considered standardized) by other agencies and tag a course one or more levels down with the that name. That's why the PADI AOW was the same as the NAUI Sport Diver, and the PADI Master Diver was, rather than a true badge of expertise, nothing more that a sales gimmick for specialty courses.
PADI had an Advanced plus course that was the same as NAUI's Master Scuba Diver and it fell on it's face. After a few years, it was taken out of the mix. If it doesn't work, don't try to force it down someone's throat. All of the other agencies have had to abide by certain monikers that PADI placed on courses. That's smart marketing on everyone's part.
Look, people aren't stupid, but s/he can be led down the primrose path. If something is working, why try and fix it. Snow Skiing doesn't require lessons and lots of people try it every year. The marketing done in that industry is always upbeat and positive. Perhaps people in this industry should take a hint from that.
At the entry level diver PADI sliced out time consuming and onerous, but essential, items (rescue, gas management, etc.) thereby making the course cheaper (and easier) for the LDS to "crank'em" on out.
They did relocate that information. Beginners don't know if they'll like this sport and the time they spend on the basic skills can be taxing to some of them. At the beginning level, those people have enough to think about to take care of themselves, much less another diver.
In skiing, that's why you have Ski Patrol. In diving, that's why you have divemasters.
Frankly I think that this approach has been counter productive for the LDSs, divers, and the industry as a whole. The only beneficiary were the owners of PADI (at the time a for profit corporation, more or less run by the head of U.S. Divers).
At the time that PADI was owned by the head of U.S. Divers, they were a non-profit organization. Although that changed when he retired and took they reins at PADI. Mistakes were and are currently being made, but at least they aren't sitting on their laurels like most of the other agencies. You learn and grow from both the good and bad.
What divers needed was better and more complete training so that they were comfortable going out diving. What shops needed was the same thing, divers growning and purchasing more advanced and expensive gear (e.g., dry suits and such).
What divers need is to get more dives, to increase their experience. Just like skiers need to get out on the slopes to get better. I've learned a lot more by actually diving than by taking certain classes.
However, for the typical consumer who's going on a cruise, my prime objective is to keep them diving after that cruise. That can be challenging, with all the other things to try in todays society.
What the owners of PADI lusted after was more case, that is to say more c-card and materials sales. So PADI cheapened (in terms of time required and quality) their certifications and made lots of money.
For every dollar that (insert agency here)__________ makes, the Instructor needs to make one also. The amount of time spent on teaching a class (depending on which one) can far too often be a loss leader. It has been that way in the past and things need to change to make it a win/win for all parties.
I don't see cost as a measure of either desirability or quality.
Really! A lot of great Instructors have been lost, because the time they put in to a course couldn't justify the lack of money they were making.
