A super lightweight aluminum folding sluice box that incorporates the newest technology in rubber rifflesÂ design. We have taken the best parts of our previous folding plastic sluice and introduced our highly successful rubber riffle design. The rubber riffle design works fantastic in both fast and slow water conditions. We have tested this riffle design for several years and are amazed at its high capacity and exceptional fine gold recovery. Easy clean up, slide the riffle section out, set the sluice in a bucket and rinse with water. The recovery riffle area is 40 inches in length, totaling 63 inches overall. It weighs only 9 pounds and folds up into a small package quickly and easily with a strap for carrying or backpacking. Stays straight and rigid, will not buckle or flex. This model is compatible with our power sluice conversion kits.
