Hey Guy, Happy New Year.
Just want to comment on that question also. For highly mineralized soils with the Tejon. To find deeper coins, you have to lower your Disc.1 down to a little lower than foil. Remember, to much Disc, you loose depth on any machine! So keep it below foil. Next, 2 Disc. you will set it up where it cracks on Nickel. If you get a good and stable hit on Disc.1, in both directions, side to side, up and down, but a crackle on Disc.2, does not mean it's not clad of silver. high Disc. did not allow you to detect deeper coins in that soil. So, as a matter of fact, you just might have hit on either one or even gold! Remember you said it only finds quarters five inches deep. Now with the Dic. lowered, you goona get better depth. The deeper the coin you gonna loose depth at higher settings.
In this video, I had my Tejon set all the way up, but that's because I was using th 5.75 widescan. But I'll show some other vid's with me using the Tejon in lower settings with standard coil going deep on silver!
