This isn't going to help but... I have tried the cheaper sensors in the past and they gave too many false positives.
I have never drilled through a pipe, but I have drilled through a cable which was running diagonally through a wall. Additionally, I once cut through a lighting cable with a wall chaser at my own home (first floor). There was nothing on the ground floor to indicate that there was a cable- that said, if I had gone up to the loft I would have seen the cable.
