[QUOTE="Ridge Runner, post: 299282, member: 3775"] Metals like Copper, Bronze and Brass can be found at greater depths than they air test at whether it is a VLF or a PI because they leach in to the ground making a much larger target in undisturbed ground, VLF's will go deeper in damp ground than they do in the dry ground, also add the halo effect and they will go deeper or match PI machine under those conditions if the Ground conditions are not too mineralized.
