Scanner Imaging Metal Detector did not see the target

The operator or user does not take a correct image of the center of the target with the Scanner Imaging Metal Detector or Image Scanner or Metal Detector Image Scanner or GPR or Ground Penetration Radar or Ground Handy radar or Scanner Detector or Manual Ground Radar Scanner In fact the target is not in the system’s view or the range that the operator or user considers as the center The desired target is imaged with the image scanner or metal detector image scanner or GPR or ground penetrating radar or manual ground radar scanner that is not the center of the target or the target does not exist in that range The vision for the answer is in the direction of discrimination and the system does not recognize the target this is an operator error
