Ground phase reading is the number,,the graph shows mineralization levels...you see that graph go 2/3 or more full,,,depth will start to suffer,,,,and with higher mineral levels,,Deus may call some deeper nonferrous iron.. Deus does work better than most in bad ground for Vlf,,,meaning it will at deeper depths in the real bad ground,, continue to call nonferrous targets, nonferrous-- but remember this is all you will know about the target.
Better though than calling say a 7" quarter a nail-- like a lot of others detectors will do in higher minerals soil.
