Want to drift the thread back to CPI's and TorqueStripes comment of never an inadvertent deployment? Seem a few have not been on the aircraft on RTB in 212man's turf (third-hand rumors and innuendo, both S92 and S76). The really bizarre thing is that they have never been found!!! You have to appreciate the irony of a Crash Position Indicator that deploys but is never found! Give me a PLB with a built in GPS anyday.
