Magnetic metal detector separation and discrimination of metals depth of field composition

Any type of magnetic detector or  magnetic metal detector such as pulse metal detector or VLF metal detector or TR metal detector… or function generator or system with magnetic waveform are not capable of separation and discrimination for all types of metals in depth And it is the lack of ability of the current of movement of the magnet that loses its initial power along the path of movement and if the magnetism spread from the searcher or coil or loop of any type of magnetic detector reaches the metals in depth, because the magnetism loses its initial power along the path. The lost motion of the magnetic current emitted from the magnetic detector does not have a high power to combine with the field of other metals and with field combination a high power field combination mode is not provided which provides a regular high power reflection from the target field in the depth towards the searcher or coil or loop or magnetic sensor return to cause the magnetic detector to respond to the intended target or metals, especially gold in the depth in a movement method with a searcher or coil or loop or magnetic sensor as a result the magnetism with high power does not reach the metals in the depth and the field reflection current is not formed and this is one It is one of the factors that any type of magnetic detector  or magnetic metal detector such as pulse metal detector or VLF metal detector or TR metal detector… or function generator or system with magnetic waveform can separate and discriminate metals in depth don’t
