The Keene A51A super mini sluice is the lightest most compact sluice box with all the features of a professional sluice. This is basically a miniature version of the A52 Keene Hand Sluice, and it is great in particular for use in narrow gullies with limited water. It includes a removable flare for compact backpacking. The aluminum box has removeable steel riffles and expanded metal screen over riffled carpeting. There is a short section of black ribbed rubber matting in the flare that acts as a quick check area for gold in that last scoop of dirt. Size 6 1/2″ x 33″ with 11″ flare. Weight 5 lbs.
