Wow, you really contradict yourself there dude. You said you would not take a chance on using "life support" equipment that was not maintained. You said it was not worth the risk.

But then later you talk about regulators that you worked on where you were not sure, so you decided to dive with them to make sure. Well, that sounds even more foolish than diving with undermaintained gear.

You did not answer my question, I was not looking for your opinion or assumptions. Again, here is my question:

"Anyway, what I was wondering is there any certifing agency or any regulations on who can call themselves regulator tech's?"
