This multi purpose package includes a removable mat for the lower sluice box, converting it to a clean up machine simply by sliding out the green rubber riffle and replacing it with Miracle Matting. It is also supplied with an additional finer woven mesh screen on the top hopper if being used as a concentrating system. The Mini Max is powered by a single 2200 GPH, 12 volt pump. The top hopper is equipped with a flood header that provides smooth water flow over a slick plate and in to a 6 inch section of miracle mat that gives you a preview to any captured gold! The material is then washed over a removable classifier grizzly screen, removing the oversized waste gravel. The bottom sluice box is lined with green rubber riffle that recovers ultra fine gold and can handle larger volumes of material. When used as a concentrating system, the lower sluice is partially covered by oversized expanded metal. When used as a power sluice you can expect a capacity of up to a quarter of a yard per hour and about a third of its capacity when used as a concentrating machine. This device is ideal for back packing given it folds up into an compact size of 36 by 14 by 7 inches and weighs under 23 pounds. The four independent legs fold up with the new pin-lock folding system with large wing nuts that make it a breeze to adjust elevation and articulation.
