Very well, then I suggest you contact the three dozen agencies and explain how they should pay for this "screening" in order for you to feel more secure about the training that you`re seeking. Once again, I don`t think this is a problem that is rampant in the industry. Does this mean we also test at home where they are most likely to partake in this behavior? I can understand the desire to bring a "wholesomeness" to the sport but to add this expense onto an already struggling recreation and to combine that with the number of independent instructors out there that aren`t even affiliated with a dive store, this would become a very difficult (and costly) task.
