A method for detecting metal using an electronic article surveillance (“EAS”) system. The EAS system includes a transmitter and a receiver. An EAS interrogation signal is transmitted to establish the interrogation zone. The EAS interrogation signal is used to detect EAS markers and metal objects within the interrogation zone. The EAS signal is received and a metal object present in the interrogation zone is detected during a metal detection cycle. The metal object is detected based upon perturbations in the received EAS interrogation signal. The metal detection cycle is periodically interspersed with at least one EAS detection cycle.
