A monoloop coil uses a single winding that functions as both the transmitter and receiver — unlike DD coils which use separate transmit and receive windings in a D-configuration. Monoloop coils offer better depth and small-target sensitivity in moderate conditions, and are the standard configuration for pulse induction gold detectors in prospecting use. The tradeoff is more susceptibility to ground mineralization effects than DD coils — in heavily mineralized conditions, DD performance can exceed monoloop performance. For goldfield PI work in the conditions where PI machines are used, monoloop round coils are the established standard.
