Highly Mineralized Soil

[mlamp20412]

Highly Mineralized Soil will cause false signal, correct? If I get a repeatable signal and dig to find nothing then recheck with the detector and get no signal, could it be because the mineralized soil was disrupted and the mineral concentration was broken up? I live near a river and within a known gold pyrite belt. I suspect this might be causing some of my false signals.
Thnx

Id say yes the way you asked it. A lot depends on the detector also. Nails are a great cause of those signal you cant find. They cause a "halo" effect as they corrod. Minerals and SALT can cause falseing, especially if you are running you detector to hot. Black sand will make some false as will HOT rocks.

Thanks for the insight. I do sometimes see some soil discolorization when digging these phantom signals. I have sent my detector in for service due to some other issues I have had. I will be curious to see if they do anythings to it and what the results are.

Thanks again!

I have a lot of problems with minerals here in Ga. In any soil that has been an old creek bed there seems to be a lot of minerals. I turned down the sensitivity and it is helping some but it still gives some false signals. Good luck.

on my dect iron will give a wider sig than a non feris sig like gold ,silver, lead,copper etc. some times a hot rock will sound like a pop can, very louad, if you lift your coil 3 to 4 in you will lose the sig or it becomes very weak. if it was a metel sig. you will still have it.i disc. with my ear . turn sen. down to get smooth tone, listen for narrow quick sig. make sure coil wire is not resting on coil,what i have done is stick my screw driver into the sig several times and recheck the sig if halo it will normaly be gone
learn how to work these areas and you will find coins or gold where other people give up.go slow.
