I wish I knew how to save this entire thread, this is really, really good. Thanks to all, the experience on the board is staggering. My very first instructor (who turned out to be a good friend ever since!) once corrected me when I called him divemaster... he jokingly made some comment about being WAY above that, and of course, instructor is certainly.
I see that it very much depends on the lds and the instructor involved. This is what I wanted to know, other experiences. I have always been told I'm a natural teacher and DM will define whether I'm good at teaching scuba or not. I do my ResQ, not this weekend but the following weekend. We do the CPR class on Friday, do the ResQ part on Saturday and Sunday. After this many posts, I'll certainly post on my completion (that's positivity, isn't it?).
I like the idea of getting included on trips for free or for discounts... that in itself would make it worth it for me! More diving!
As a D/M candidate, besides being a tank monkey, tag line monkey, float monkey, errand monkey, etc., your responsibility is to learn the agency's procedures and techniques. You will then eventually begin to demonstrate to students the various drills and work with those having difficulty, with your instructor close nearby. After enough of this, you will ultimately become certified as a D/M.
As a D/M you will practice working with students one-on-one, and you will take pairs of students on tours. And you will watch over the students when he/she cannot, such as when he/she is performing CESAs with each of them.
During the ITC/IDC you would then learn how to teach a class, and how to introduce fresh students to the equipment and to diving.
An instructor would be hard pressed to teach a class without at least one D/M or A/I or T/A or D/C. Therefore there is real value in being a certified D/M (etc.) to the instructor.
You can leverage off this real value by searching for an instructor who would prefer to have you assist him/her for a season or two, in lieu of charging you a class fee for your D/M certification and your DAN O2 class. That would then be worth about $1000 to you, which is a lot more than any store in England or in the USA is ever going to pay you.
Alternatively you can feel free to PUT ANOTHER DOLLAR IN on your own, and not reciprocate with any sort of commitment. However there is really no way around the commitment, because you need the experience after all anyway.
Look around. Find out what your options really are. And don't fall for the first honey-tongued spin meister selling his own program. That is how you would then steer clear of the rocks and shoals that I have dubbed 'the blood sucking vampires.'
