VLF Detector Operating Modes

Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.
Imagine for a minute the year is 1850. You’ve read and heard that gold was discovered in California and the creeks are so rich you can just scoop it up with your hands.
I recently grew complacent, and it caused me to make a mistake that resulted in the loss of a mining claim. It brought my mining plans for the summer to a complete halt.
Even with my favorite top-of-the-line gold detector there were several false digs. Many of the hot rocks gave a solid signal that was too much like a nugget to ignore. After trying several tests I just dug everything because it is better to be safe than leave a big, deep nugget for a more diligent gold hunter.
I had never run an impact mill before, but anything involving rocks, water and a big electric motor sounded great.
