jharhed,

I don't know what the ground conditions are in LA.,but here is a trick: Take a NON G.B. machine and not one that auto tunes,find a patch of clean ground, tune the detector with the coil a couple of feet off the ground, if the change in threshold slowly changes when you lower the coil it's light mineralization,if it changes rapidly and strongly then it's heavily mineralized. The problem is whether you have enough experience to tell the difference.
If you have any questions concerning the Tesoro's,let me know, I'm a Tesoro dealer.
