Achieving Accurate Metal Detector Discrimination
December 2019 by Chris Ralph
Your odds of going home with gold will be higher using the discrimination mode, even if you might have misread one of the targets you rejected.
There are currently three controlling agencies or entities over suction dredging in California—and you can make that four if the state legislature decides to further muddy the waters with additional legislation to block suction gold dredging in the state.
After a short time, the tailings pile can get very large, and can actually block the downstream end of the sluice box.
It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.
I am going to break bedrock down a bit and explain my view of the varying scenarios I come across in the field.
The amount of gold in the traces from the low-grade scattered veinlets may be much more than the traces from the small but rich pocket, at least until the pocket hunter closes in on the rich pocket. Further confusion arises if the prospector stumbles across a placer deposit on one of the higher peaks.
“JP, is it possible to make a living looking for gold with a metal detector?” I get asked this question a lot...
Back at the entry point of the mine, we took turns slowly crawling down the slope leading into the mine portal with our metal detectors, hard hats and flashlights. The mine was hand dug and is about 75 yards long.
