Talking to the Dive Shop, they said it is cheaper to enroll the Divemaster course (plus specialties) rather than paying for avulses courses. He show me the prices and the courses are cheaper when its packaged with the "career plan".
I don't intent to work as a DM neither show off my DM credential. I just like to learn more about things that I like. And if the cheaper path is towards a DM, why not?
Does it make sense? Or I just describe a Master Scuba Diver (MSD)?
A few thoughts:
Enrolling in the DM course, plus a few specialties, because it's "cheaper" is on my list of the top 10 most nonsensical things I've heard from a scuba shop. The "career plan" selling point is also on this list. (Does the "career plan" include a "career offer" of employment?)
The DM course is expensive and time consuming. What do you learn? The best analogy, I think, is...
---> The OW course provides students the basic skills they need to be open water divers. They then use their experience to develop these skills.
---> The DM course provides students the basic skills they need to assist other divers, work as a guide, work as as an assistant to an instructor in a class. They then use their experience to develop these skills.
In that respect, the DM course won't necessarily provide you with better dive skills. It will show you the basics of what you need to know to work in the dive industry. If you're looking for skills you will use when diving, please consider the chorus of responses on this thread that are directing you to courses more relevant to what you want. (Also, your dive shop will tend to direct you toward the classes they teach... not necessarily the classes you need.)
Master Scuba Diver? Not really what you're looking for. It's a marketing ploy, primarily aimed at new divers that want a card that will make them believe they "outrank" those around them. Find courses that will teach you useful skills; avoid courses that have fancy titles of "___________ Diver"
