[QUOTE="Ded Driver, post: 489963, member: 12692"] I think you've missed the point BigL.. any Techs on here please correct me if Im miss-stating this. A PI machine does not transmit an RF signal like a VLF (that transmits a continuous sine wave of a certain frequency). In a PI machine the Tx pulses energise the coil. The machine then samples & analyses the rise & decay rates of the induced Rx signal . Hence the term "Pulse Induction'. [/QUOTE]
