A novel pulse‐induction (PI) metal detector (MD) is proposed to decrease the saturation time of the output voltage and increase the detection depth. The proposed MD utilises a receiver with a time‐domain bucking circuit. The bucking circuit decreases the output voltage significantly without a target, so that the output voltage can be amplified more before becoming saturated. To demonstrate the performance of the proposed MD, it has been fabricated and measured. The measured output voltage shows that the saturation time is reduced and that the detection depth increases in comparison with a conventional PI MD.
