Here is a little video of exactly what I was talking about a few months ago in my “How to find gold” Series. Where good gold nuggets are found with a metal detector, there is certainly good fine gold to be had with a dry washer. See how they cleaned right down to bedrock with vacs. This is the way to do it, straight from the expert: Rob Allison. Enjoy!
This is a really cool video with some good underwater shots and a nice cleanup at the end. It’s neat to watch the suction dredge pull material off the bedrock underwater. Enjoy!
