Ground Mineralization Question

[SaginawIan]

Absent a metal detector, are there geographical indicators of an area having high soil mineralization? I'm im Mid-Michigan and hoping I can get away with a preset ground balance detector without having problems.

Ask at your local county's Cooperative Extension. The farmers and growers need to know soil minerals for what to add or compensate for in their fertilizers. They may have a general map of the topsoil conditions in your area.

Often 'hot rocks' can tell you a lot about your area, or at least mine.
Yeah maps are good to, if there are mines close by there is probably high mineralisation (obvius?)
Many modern detectors have an automatic ground balance, so you don't have to care about that unless it's really bad ground so to say.
Have a nice day!

Be careful, some detectors claiming automatic ground balance are simply preset.

In my area the ground changes as you walk.
Ground Balancing is very important. If its auto then you should be ok.
But if its preset find out to what degree. Usually a window of (example) 17-27.
Higher min. will make the machine talk to you. Chatter, sputter, lose depth ETC.
