And you didn't read what the op posted. He wanted to know if the PADI course would be a waste of time if the course did not teach any useful skills. I responded that I received useful skills but added a response that made it clear that it depends on the instructor.
No - I read it - clearly YOU didn't.
At the end of his post the OP SPECIFICALLY referenced dive operators permitting him to dive solo:
"...... So that the Captain on an occasional charter trip does not have kittens over the thought of me being interested in a solo dive......."
So EFX stop trying to justify your early panty-twist error.... You were wrong... Move on.
As a PADI MSDT I am fine with teaching the Self Reliant Course, I also teach the SDI Solo course. I've seen dive ops turn away the one (PADI) and not the other (SDI) for solo diving.
So if the OP is saying he may want to dive solo- whether it's accepted is indeed important info.
I, and others, addressed the fact that some operators will not accept the self reliant card, but do accept the SDI Solo card.
