Science of metal detecting and treasure hunting.

However the fact that average PI metal detector can detect targets deeper under ground than average IB detector, is due to the very high level of the transmitted signals (few hundred volts pulses). With that allowance in their basic principal the PI metal detectors can win almost any competition for depth.
