This was from last weekend. Had a good trip and got some chunky gold. It shows my current recirculating highbanker in action. We ran 56 buckets of -1/2" material and tried out some alum to clear up the supply water and it worked! There are many past versions of my recirculating highbanker on my YT channel if interested. Season 1 has the primitive version, season 2 is a bit more refined and season 3 discussed the vortex principals.
