One of my instructors warned me that some technical divers over-pressurize their tanks routinely and then sell them on ebay before they will fail their next hyrdrostatic test. I haven't encountered that myself, though, so I can't be sure if that's just legend or if such unethical cavemen do in fact exist.

I would say its more legend than truth. First, it's pretty difficult to know when a tank is going to fail hydro. Second, as Diver0001 pointed out, tanks are heavily over engineered. And third, consider the pressures used to hydro a tank. Typically, they use pressures of 150%-166% over the rated pressure. So, for a 3,000psi tank, they develop pressures of 5,000-4,500 psi. In crosshairs case, with HP100's, they'd pressurize to 5,740-5,160 psi; still far higher than he pumps his tank. And lastly, at the pressures that would make a tank fail hydro, the diver would probably be damaging his regulator.One of my instructors warned me that some technical divers over-pressurize their tanks routinely and then sell them on ebay before they will fail their next hyrdrostatic test.
