MPF (Multi Period Fast) technology incorporates extremely fast Pulse Induction switching between Transmit (Tx) and Receive (Rx) detector signals. Therefore minimal residual transmit signal is present during the receive cycle, enabling clear sharp detection of very small gold.

MPS Technology Logo

MPS (Multi Period Sensing) is Minelab’s advanced Pulse Induction (PI) technology that transmits pulses of different time periods. MPS also samples the receive signal at multiple time periods allowing target signals and ground signals to be separated. This effectively removes the ground signal from even the most highly mineralised ground while still being sensitive to both small and deep gold. This achieves superior depth in extremely mineralised ground.
