Selectable Frequency vs Multi Frequency Detectors
March 2017 by Steve HerschbachI like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
We chose this particular area because an old channel had run here at one point and had been heavily worked on top of a mountain hilltop. Erosion patterns cut deeply on each side, leaving the channel exposed. The erosion cut sharply, dropping into ravines far below.
When everything is still dry, one of my favorite methods of prospecting is using a straw to blow out small cracks and crevices that dot the exposed bedrock along a stream.
...more folks rolled in on Saturday morning and many were eager to venture out onto the Sleepy Bear property—all 415 acres—and try their luck at finding some gold.
The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.
The problem is that extracting gold from hard rock is often a lot more difficult than processing placer gravels. Still, there is some very high-grade ore out there in many old mining areas.
Due to the lockdown, I spent lots of time indoors this spring and I decided to add a drone as a faithful mate in my research.
I cleared the connector by poking a small Phillips screwdriver through it. To ensure the bore was clean, I dunked the connector into some water and then blew it clean with my shop air compressor.
