6 weeks????
My OW course in 1975 was SIX MONTHS long...
Ok, probably too much..
But even today a FIPSAS-CMAS course is three months here!
I do not agree with you that it was a good idea to demolish these well-featured (and task demanding) OW courses to the point of releasing a diving certification in a weekend.
Sorry for being "old school" on this.
And personally I think that the continuous reduction in number of new divers is also due to the fact that it has been made too easy.
For a youngster it is not presented as a difficult, task demanding activity, as it was for me in the seventies.
If it is a sport suitable for a 60 y.o. fat lady, who cannot even swim without fins, it cannot be something exciting for a youngster...
