Just a little look into the world of sluices one realizes that this is an evolving technology. There are tons of great ideas and products being created for the purpose of bringing gold mining to the common public. I was inspired to mock up some of my own ideas on a re-configurable and portable sluice that can be used for a multitude of uses, the transformer of portable sluices so to speak.
I mocked this design up in SketchUp download the skp file below.
