I do not get it why should Tec training be a requirement and what do you learn in a Tec course that in any way make you better qualified to clean parts install O rings disassemble and and assemble a simple mechanical device. Turn an allen wrench to adjust the pressure with a gauge or add or remove shims to adjust the pressure. lube with proper lube where required check for leaks and proper function.
How many of the worker’s in the factory in China even know how to dive?
I bet some of the workers in the factory do not know what the parts they handle are for, what a regulator is, or what it does
Is all the warranty service done by Tec divers?
Is it the requirement for all employee’s at all dive shops to have training in Tec diving before they work on a regulator?
The silly requirements just perpetuate the Gray market of parts and people that truly want to do it right because of a bad experience. They do it any way but often improperly because the cannot get the proper training or part’s from the industry.
