The Best Cavity Finder is basically a Finder with the ability to distinguish a natural Cavity from a human-made Cavity or one that has been changed by humans, and the Cavitys formed by the changes in the Earth’s Layers or the combination of soil movement or the pressure of the flow fields can determine the conditions of the Cavity for the Finder.

create a Cavity Detector or a Cavity Detector device that the Cavity Detector device must have the ability to Detect in its circuit to Separate these Cavity conditions or Ground changes or Field pressure and the circuit design principles of the Cavity Detector device must be such that it can Detect pseudo   Cavity Error factors Detect, Discriminate and Separate man-made, and the Cavity Detector circuit should be in the  Adjustments or settings to establish communication in the Detection, or the circuit should be designed in such a way that by changing the Adjustments or settings, this Group of Cavitys can be recognized or Discriminated or Separated in the natural state, and only the devices A Cavity Detector that has the ability to change the Adjustments or settings of a natural Cavity or changes in the Ground that shows a pseudo man-made Cavitys , a Metal Detector or a Manual Ground Radar or Ground Handy Radar a Frequency type Mine Detector with a VDI count in Edit and Level and volume Settings or Threshold Surface and Size Adjustments and other related settings.
