The type of soil and minerals of the earth are different
Some of the soil and minerals of the earth are in a mountainous state that is hard and hot rock but in very contaminated lands it is in a contrasting state of different mineral composition which forms different high energy fields which in the working condition with any metal detector or detector the hard ground or hot rock situation is like very hard and contaminated mountains with the pressure of particles of electric charge mixed with an inappropriate composition
In the mountains or any condition where the ground is hard or hot rock or the ground is contaminated with contrasting minerals and soil the metal detector or any type of frequency detector with a VDI number in the Edit and Threshold of the surface and size can pass through unstable high energy fields in a high temperature state and one factor of that heat is related to the energy in the radar circuit frequency which has the power to establish a connection with the heat of hard ground or high energy fields with a specific heat of the same range and the radar circuit frequency passes through this high energy field condition that has a higher temperature to It does not lose its original power and takes gold or silver and all kinds of metals deep in the earth and separates and discriminates
