A device for use in detecting metallic objects includes a processor and an electromagnetic radiation source in communication with the processor. The electromagnetic radiation source is configured to emit radiation to heat a metallic object. The device also includes a temperature sensor in communication with the processor. The temperature sensor is configured to detect heat emitted from the metallic object. The device also includes an alarm configured to notify an operator of the presence of the metallic object responsive to a determination by the processor that a temperature threshold has been exceeded.
