On our side of the pond there is/was a device called the "Polar Toneohm". It used a hall effect device to translate the current flowing in a track to a tone - rising pitch, higher current. These could be very effective in finding shorts in power rails etc, also in multi-layer boards. Google "Toneohm" and you will see.
