While it can be amusing to see where these "PADI vs Agency X" threads eventually go, I think the basic point that got lost in the last few pages is that at this stage the OP doesn't
need to commit to any particular agency -- especially if he doesn't know where he's going to be living in 3 years. As StreetDoctor put it (perhaps a bit too bluntly
), he can get out and dive without having to worry about which agency he'll ultimately affiliate with. In the process, and particularly once he gets to the DM level, he'll discover that there's a difference between diving for pleasure and diving for a living...and hopefully find that both have their own rewards.
I've done all my training with PADI, not because I think PADI is superior or because I have anything against NAUI, but rather because NAUI has virtually zero presence here and PADI's local support is fantastic. If I had the opportunity, however, I would have trained with multiple agencies just to experience different instructors and teaching methodologies. Assuming that OP can locate good instructors from different agencies, there's no reason why he couldn't do, say, AOW with one, rescue with another and DM with a third...and based on those experiences, consider which one best suits him for OWSI. Even at the OWSI level, you're not committed for life to that agency and are free to cross over to other agencies without forfeiting your membership.
Robert00: I say ask all the questions you want, but take the answers with a grain of salt (foot of sea water?). Divers seem to have strong opinions on everything -- just wait til you get involved with the DIR crowd -- but despite what some claim, one agency isn't universally "better" than another since that's entirely subjective. What you'll find is that one may be a better fit for you based on things like location, language, local support, mentors, teaching philosophy, etc. If you have the skills, discipline and motivation, you can be a great instructor with any agency.
