This control allows you to update your standard Desert Fox into a Variable Speed Desert Fox Spiral Gold Panning Machine.
A speed control is very useful when you encounter unusually heavy black sand. This control reduces the wheel speed up to 10% without affecting the pump speed. This allows more time to wash the black sand out of the spirals before dumping heavies into the catch cup.
Too install this control on your Desert Fox, you will need a drill, sodering iron and some simple hand tools. Instructions included.
