Frequency radar or frequency metal detector or frequency detector with VDI number in Edit and Threshold emits the Surface and Size of the frequency field that this frequency field has a strong electric field and a very weak magnetic field within the flow of energy and radiation that the charge current Its positive electric field is high and this combination of two strong electric fields with a high positive charge and a weak magnetic field with a low negative electric charge basically forms an electromagnetic field with a positive electric charge in the frequency field and atomic vibrations and oscillations and the number of neutrons and protons and electron and molecular electric charge of metals and sources and materials are different and this is the factor that the energy and radiation or specific frequency of metals or sources and materials and materials are formed separately and specifically according to the molecular currents expressed and each of the sources or metals or gold or silver or minerals have their own frequency and reflect the same current in the field state in the reflection after combining and transforming and completing the capacity and one of the reasons that can detect the frequency of objects and types of aircraft in the sky a frequency with VDI number and Threshold to separate the surface and Size of metals and materials from each other
