The present invention, thanks to the horizontal positional tracking unit (20)—mounted to a hand-held metal detector (10)—consisting of optical flow sensor lens (22), an optical flow sensor camera (21), an optical flow sensor processor (23), a height sensor (24) and an IMU sensor (25); allows the calculation of the depth of the target (60) by tracking the horizontal position while the user freely sweeps the search head (11) of the metal detector (10) with the “optical flow” method and using the metal detection signals received from many point positions around the detected target center with this position; so it relates to a method of measuring a target depth and a metal detector using this method, which allow calculation to be made independently of the type and practical the size of the metal.
