A simple vid on a small gold coin, 30khz vs 15khz in mineralized soil.
You here folk say there low/mid freq machines pick everything up, 'small and large', yes it may in an air test, or on targets just below the surface, but It shows what you may be missing if your soil is mineralized and your running in this case, a sub 15khz detector
