First, I would not be doing it to get rich. I just wanted to know if I could temporarily live in a location and make enough money to buy food, etc. Same thing goes for the liveaboard...just wanted to know if they hire DMs and if they got paid anything. Wouldn't mind working on a liveaboard for a year of so.
So I guess what I'm hearing is that DM training is mostly a stepping-stone to instructor and that there a few benefits in the way of money of actually improving your own dive skills as opposed to improving your demonstration/people/teaching skills.
Do you learn anything more useful like how to fill tanks and use the compressor? How to make minor repairs on gear (suits, regs, bc)? Anything like that?
You do not usually learn about compressor maint/repair or repairs on gear..Has nothing to do with being a Dm..You do learn how to assist in a class and supervise certified divers...and hopefully get to dive at a lower cost-don't even think about making any $$.
Most resorts do not hire someone with only a DM certification unless they can bring something else to the table such as outboard/diesel mechanic-captains license.
They still would much more likely hire an instructor because the instr can function as a DM when needed or as an instr when teaching.
If you do not have a specific LDS that will work with you do not go for SSI, it would be difficult to locate a place that will work with you.
With a PADI certification you would have a better chance at finding a facility that will work with you as a DM and when you become an instructor.
I would also add that you should do your DM course with a facility locally that you would like to work with and from an instructor that has taught at the least 3 DM courses, and the best option would be a IDC staff instructor.This way if and when you go for your instr certification you have a better chance of getting classes there,as they know you .When I owned a facility I would not hire a unknown instructor unless they had vast experience and were known in the local industry, I never used a DM certified elsewhere.
Courses locally go for $500/$800. range and usually do not include any books or boat fees.
Once certified as a DM some instructors may give you a few $ to cover your gas/air fills if you are lucky, I do,but it is not that often that I need a DM.
Feel free to call me if you have any other questions.
