This wash was not far from where I once dug a half-ounce nugget, so I knew there was gold in the area.

The type of mine dump that is best for metal detecting are the ones that consist of mixed sizes of rock and are located near some sort of excavation, commonly a shaft or adit. Sometimes the piles located along a trench dug by the miners can be productive as well.

There were iron stains all over and even a few places where I could see iron trash sticking out of the bedrock. These would be ideal spots to start with as the gold travels with the iron and lead.

If Epd is larger, then the compressor will be spinning faster than the manufacturer’s maximum specified RPM and might destroy itself. If this happens, then the compressor again might not produce enough air to support a diver. Neither is a desired outcome.
