USGS has spent little time in my area around old homesites that have burned with such ferocity that tin roofs end up being molton globs that permiate the soil along with iron oxide clinkers from coal fired heating stoves . Even the fired red clay brick shards will turn up hot .Ernest T Bass said:According to USGS, very little of U.S. has mineral content that would require the use of a manual ground balance. Most of them in the Northwest. Too many amateurs think they need manual GB because they don't learn how to operate their auto GB machines properly. Then they deal with huckster dealers who say oh you must be hunting in a high mineral content soil, you'll need this XXX machine that costs three times as much as the one your trying to use. How about some expert here speak up and tell us what mineral the soil has to be high in for it to cause problems for auto GB ?
We soil test 80 or so acres of our cultivated fields each year with none of these results , but when I detect the homesites most of my time is spent digging trash of this nature.
