This is the plans for the Jack Swift River Rocker
It works in slack water where a Sluice box won't
To use it you adjust the legs to touch the bottom and the bottom of the box to be level with the top of the water. Then add your dirt and gravels. Rock it back and forth allowing water to enter one side and flow back out the other side washing the material. After enough rocks to wash the gravels well you rake out the big rocks and and more material.
