Hey everyone,
I'm interested in eventually doing the DM course. Even if I don't end up working in the industry I definitely wouldn't mind the new knowledge I learned and the chance to travel and dive (a lot) somewhere new!
If you want diving knowledge, take your Rescue and Intro to Tech and read Deco for Divers, by Mark Powell, and The Six Skills, by Steve Lewis.
If you want to travel and dive a lot, then travel and dive a lot. You don't have to pay someone to give you training in order to travel and dive a lot.
If you want to improve your diving skills, take Advanced Nitrox and Deco Procedures, or GUE Fundamentals. I would push towards AN/DP, because nothing in diving is so freeing as being properly educated and trained so that you are no longer bound by NDLs.
If you do all that and your traveling and come home and decide you want to actually work in the industry, THEN do a Divemaster program wherever it is that you want to work.
Well, that's a different approach. My guess would be that if you are able to complete the course logically you would be prepared to jump right into working.
I don't think that is a valid conclusion. Based on the actual standards and requirements to obtain a Divemaster certification, I think it's entirely feasible to meet all the requirements without actually being well prepared to jump right into working. I think it just means that you are now prepared to learn how to work in a particular place.
From what I can tell, there are (at least) two different approaches to certifying DMs. Some shops do it "old school" where you actually do what boils down to an internship as part of your DM training. You get the training you need in order to meet the DM cert requirements while at the same time you are getting practical (basically, on-the-job training) experience in how to actually work in the industry.
But, the other approach is places that separate the two things. They provide the training to meet the DM cert requirements to people who take their DM course. And then they have a separate "internship" (aka OJT training) for DMs who they want to actually have work for them.
For places like the latter, I don't think it's safe at all to assume that a person who has just completed their DM cert is ready to jump right into working.
