How come SDI/TDI has a good and active presence here and PADI or NAUI don't?
The best presence any agency can have on ScubaBoard are the instructors who have chosen to teach for that agency. In this respect, PADI has some excellent, and very active presence here. Three who come immediately to mind for me, personally, are Boulderjohn, Diver0001 and Peter Guy.
Boulderjohn is one of those people whose posts I notice ... because I have found them to be accurate, informative, and phrased in a way that would make people WANT to hear what he has to say. Respect is earned, he's earned it. PADI couldn't possibly ask for a better presence.
Diver0001 is someone I've known here for years. Back when I had just become an instructor, with a lot of ideals and energy, he was one of a handful of people I would ask to review the material I was creating for my students. His insights were more than helpful ... they often gave me a whole different way of looking at a topic that I hadn't considered before I had read his comments. Any agency would be proud to hold him up as a representative ... and any student would be well-served with the kind of insight he brings to dive instruction.
Peter Guy is new to dive instruction ... but not to diving. He's someone who, by nature, dances to the tune of his own drummer. PADI needs instructors like that ... people who look at every particular and ask "why" ... any agency could benefit from that kind of instructor, because "why" is the most important way to start just about any question involving scuba diving, and an instructor who asks that question will be able to provide a reasoned answer when his students do.
PADI ... like any agency ... is only as good as the instructors who represent it. Sure, there are poor instructors in the organization. But the same can be said for EVERY agency ... even some of the niche agencies whose numbers are small and who purport to a higher standard.
But the agency doesn't teach people how to dive ... instructors do. There are lots of great instructors who frequent this board, and who willingly share insights that most divers will never get from the class curriculum. PADI is well represented by those who I consider the best ... and ScubaBoard would be a much poorer place indeed if they were not here.
You really can't judge the quality of dive instruction by the agency someone is certified through ... you can only judge it through the competence and dedication of the instructors who provide the training.
That's why agency-bashing is such a wasted effort ...
