Me testing out an earlier version of a wood drop riffle high banker I had built. Took it to thermal city to test with. The grizzly 4 mesh screen was good for washing and inspecting the rocks but it caused the rocks to hang up. Newer version has a bar grizzly instead of the mesh and plastic water deflectors channeling all the material and water from the top grizzly into the bottom sluice. Also I changed the top grizzly so the angle of both sections is now the same. The first section of the high banker has 12 inches of miners moss and raised expanded metal with grooved carpeting underneath the grizzly. Second section of the sluice is just 1/2 inch drop riffles with 1/8 inch smaller drops inside them, by 3 feet long.
