Nothing gets Gold as Quickly and as efficiently as My "UnderFlow" design, Please check into all my Videos as I can post them. To show ALL capabilities of Placer Gold Production and putting the "GOLD or PLATINUM" in your Pockets! (Not to mention any Gemstones along the way) - Large Scale Commercial, and Dredgers would also apply.
