I've already commented I'm considering intro to tech too, I will check with the dive shops directly when I'm onsite.DM will not make you a better diver. It is not for that as others have said.
The other consideration is have you considered how many people you will piss off volunteering to work at a shop and dive with people?
Those are jobs that people should be paid to do. You volunteering may mean the difference between a local being able to eat or not.
In some areas it will be illegal to work without a work permit or visa.
It is true that there are segments of the industry that seem to encourage taking advantage of people and using them as free labor under the false pretense of being an "internship" that is really more like indentured servitude.
Working for free or "volunteering" devalues the professional ratings that many of us worked hard for.
It is also why in some areas you can swing a dead rat and hit half a dozen dive "professionals" who have been used, abused, and are now burned out working as bartenders, wait staff, housekeepers, and selling blood and other body fluids to make rent.
Take some tech classes if you want to become a better diver.
I don't think it's so easy to volunteer in Thailand, I will probably do it as a course and not as an internship.
I've found only one place that offers internship and for some reason it's double the price than the course, it kinda defeats the point. Also I would definitely not work illegally.
