Do you have specific (like an Arduino or specific coils) already? Inside The Metal Detector: Overton, George, Moreland, Carl
Circuits that use balanced coils to cancel out the primary transmitted signal, only triggering an alert when a target disrupts that balance.
The dominant technology in modern coin and relic hunting, including in-depth explanations of ground balance and motion filtering to eliminate ground interference.
The book bridges the gap between complex electromagnetic physics and practical, open-source benchtop engineering. Do you have specific (like an Arduino or
