I had to go through the whole Tech Deep course ...I then had to do all the other stuff to become an instructor (skills, passing the exam, etc.). Where is the zero to hero you are talking about?
Just that.... but for recreational instructors of zero prior tech experience.... who go through that whole process in a fortnight...with only the bare minimum prerequisite of deco dives...
You really seem to be saying that if a PADI instructor learned to dive first first from a different agency, they are much better than if they were initially trained from PADI.
What I am saying is that the 'first generation' of PADI (DSAT) tech instructor trainers crossed-over and typically brought vast amounts of tech experience with them. Subsequent 'generations' of tech instructor trainers were developed in-house... knowing only the DSAT/TecRec syllabus. Each successive generation suffered a skill fade.... (
in general, of course).
This also recognizes that, in recent years, technical diving has become much more 'mainstream'.... and desirable (re: profitable) on the IT and instructor resume.... in turn, acknowledging that a percent age of 'pros' made a decision to quickly 'train up' in technical diving merely to add to their teaching repertoire..... rather than having any deep passion or interest in technical diving for themselves.
I've met a dismaying number of technical instructors and tech instructor-trainers who
only ever put on technical diving rig when they have a rare and occasional tech course to teach.... and what they
do teach is limited entirely to the contents of the manual/syllabus (
because they know zero beyond that....)
Since it is possible the people YOU are training right now will go on to become instructors, that means the people you are training are inferior to people trained by other instructors in other agencies. Why is that? What are you doing as an instructor that is producing these inferior divers?
Where do I fall in the mix? I was a technical diver (TDI) for years before I became a technical instructor (DSAT, then TecRec), who also qualified to teach tech with ANDI (but, neglected to cross-over tech instructor to BSAC and SSI)... and have done in excess of 2000 technical dives, often with divers from other agencies (IANTD, GUE, UTD, RAID etc...)...
The point being, my experience and knowledge is not limited to sum content of a single agency syllabus and manual....and neither are my training courses.
A diver.... trained by an instructor.... trained by an instructor trainer... all of whom have a sum experience from a single agency manual/syllabus is pretty limited in may facets. That's true of any agency, not directed specifically at PADI.
