Metal detectors detect metal and also make a sound to acknowledge that a metal is buried inside the surface.

There is no actual calibration with any metal detector that you would need a technician for. You are in fact calibrating it when setting it up to detect the metal test samples. The samples are the control and the adjustment in sensitivity is your calibration to those samples.
