A method for reducing a delay, between a transition of a transmission of a metal detector and a process of a receive signal received by a receive coil of the metal detector, due to a critically damped time constant 5 of the receive coil, including: introducing a negative capacitance into the receive coil to reduce the critically damped time constant.
