Frequency radar or any type of frequency detector has a special circuit design that every person is not able to design a frequency radar circuit or any type of frequency detector and design circuits of frequency radar or any type of detector or metal detector or GPR or ground penetrating radar or ground radar Manual or ground handy radar or mine detector or metal detector with scanner or antenna metal detector (same as long range detector) according to the conditions of frequency emission in the state of fields with positive electric charge and from magnetism in emission by direct voltage transmission to the antenna head or frequency sensor or searcher in design circuits According to the principles of radar they do not use from low frequency to high frequency or in principle the magnetic emission current does not play an important role in the frequency propagation of frequency radar circuits or any type of frequency detector and the design of frequency radar circuits or any type of frequency detector is exclusive in the world and among many sciences It is complicated because a strong magnetic field is not used in the broadcasting of the radar frequency band and in general the design of circuits according to the principles of radar is exclusive from high to low frequency and few scientists in the world have knowledge in this field and therefore less in the world with technology You will encounter frequency systems designed according to the principles of low frequency or multi frequency radar which can distinguish and discriminate gold in depth during testing according to scientific instructions and the design of circuits for any type of detector or metal detector or GPR or ground penetrating radar or manual ground radar or ground handy radar or mine detector or image metal detector with scanner or antenna metal detector (the same long range locator) according to the principles of low frequency or multi frequency radar is exclusive to several industrial production complexes in the world
