Metal detectors where you are sensing the location of the minerals by means of a thorough survey of a piece of land through them, and as they approach the area of the presence of minerals it makes a strong sound to alert the presence of a metal in that area.
The search for metals is started by rounding the device from an area and if the noise strength and the degree of jamming increase, this is proof of the presence of a metal in that area, and then the drilling and prospecting for this metal, taking into account that this device is simple to install and used to detect the minerals found in a For the outer layer of soil.
