Edit and Learn are of tremendous value and worth the entire section called Advanced. There are some important considerations that will help to clarify this statement. The Explorer and VLF detectors are designed to operate in the presence of a TARGET VOLUME. A target volume is the complete soil matrix which includes all minerals and conductive materials. If we take a detector that use manual ground balance and go through that drawn out procedure of lifting and lowering the coil to the soil as we turn an analog potentiometer till the threshold does not change or has the slightest change what happens if there is no target volume? The ground matrix is has nothing conductive to report to the electronics. Some will display something that tells us the detector is in the DEFAULT ground setting. We need a ground setting for the detector to work as designed.
This is my point in all that which is what if we test targets in free air? We don
