Metal Detector Testing Methods
February 2015 by Steve HerschbachIt will not be any easier than on your table at home, and so testing a very small test target like the ballpoint pen can tell you immediately if a detector is suitable for looking for tiny gold nuggets.
I frequently get asked, "What should I look for when I am out prospecting that will tell me there are good amounts of gold present in the ground?"
So, how much rain does it take to cause a major movement of gravels in a stream and redistribute the gold? The technical answer is enough water to move the bed load of the river.
After finding little specks and occasionally little nuggets all season, I had finally reached something economical and interesting! This had never happened before along the Pellice Valley in Italy.
I probably swung over a few targets without noticing them. My first target came about ten minutes later as I went over a part of the high bench in this wide section of the dry wash.
Micro blasting can be used to take down hanging rock, separate minerals from overburden, and collect gemstones and other high-value product with minimal damage.
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
Besides the EPA issue, our major priority is to work on the proposed amendment to the National Strategic and Critical Minerals Production Act (S 145), a bill proposed in the Senate by US Senator Dean Heller (R-Nevada).
