ground mineralization

[nowwhat]

got a question thats been bugging me, I live in Shelby county and am wondering about ground mineralization, how much there is etc. I've been told the iron ore content is high here in central Ala. and I know that effects detecting. Anyone know anything about this and how do you deal with it ?

I don't know about the mineralization in central Bama (I'm in N. Bama), but a manual ground balance machine should allow you to cancel it out.

The ground mineralization can change in just a few feet or stay the same for yards. To get the most use out of a detector you need to have a ground balance control where you adjust for the same tone in all metal as you raise and lower your coil over the ground. Natch, there can't be any target under the coil.

The other option is to have a high end (read $$$) that can adjust the GB automatically. Manufactures used to advertise their detectors as automatic when in fact they were just preset. PI detectors aren't effected by mineralization but have almost no disc. Minelabs ignore iron and are almost as deep as PI's and for that reason are favored by many hunters.
