The very popular Keene three stage "Super Pan" ! This pan has three surfaces that perform specialized tasks.
First - the coarse riffled area (three riffles) is used to "rough out" the majority of the material.
Second - the textured area is used to pan any remaining black sands.
Third - use the "smooth surface" until only gold remains.
The green color shows both gold and black sands well. The pan is 14" across the top, 7-7/8" wide across the bottom, and stands 3-1/8" tall.
This pan does not have a drop centre, to more easily transition material onto the sides of the pan for separating that last little bit of sand.
