Use a smaller coil. Hold coil a few inches off the ground. Or get a pulse induction machine.

Since the Silver umax is a preset machine, you'll have to modify your techniques. Hold the coil at about 2 inches off the ground THEN turn on the machine and adjust the Sensitivity to about "4" to start. You can't set the Sens. too high in highly mineralized soil; especially with a preset machine. Allow the Silver a few seconds to settle in and start hunting with s-l-o-w coil sweeps. If you can afford to get the 5.75 inch coil for your Silver, it will certainly help. As a side note, all umax coils will work on all umax machines AND they work on the DeLeon, too. That's just if you plan to add to your equipment.

What you see is you are not going to get any depth in heavily mineralized ground (wet is worse yet) with a VLF and that includes two-box machines. You can always bury/place a target and see how deep you can adjust your machine. Some mineralized ground is even difficult for a PI machine.

Back in the "old days", ::) when we tried to use a BFO in mineralized soils, we had to scrub the ground with the coil and dig the louder signals or the "nullified signal; depending on what you were after. With today's machines, the nullification technique is not too possible, but the louder technique should be; if you MUST search such an area. Come to think of it; why wouldn't you want to detect such an area? After all, that is the type of difficult ground that most detectorists would not bother with. Think of all those goodies hiding in a place like that. ;D
