[QUOTE="XLOOX, post: 675846, member: 16174"] Conductivity switch on TDIs latch in each position, High, All, Low. In the High / Low position they cut off the Top/Bottom of the signal wave form. It is a rudimentary but effective form of iron discrimination. It works in a bit different manner to the VLF machines type of discrimination so a TDI will mask and see different objects to a VLF. its not necessarily better, just different, which is often enough to find you that piece that others missed.
