Gold Buddy Mini Sluice. The Gold Buddy Mini Sluice has bent flared intake. The lightest, most portable aluminum sluice available. Great for backpacking. The GOLD BUDDY Mini Sluices all have a revolutionary riffle system that is precision laser cut from a single sheet of steel, and then zinc plated. This produces a very lightweight but strong riffle system and the zinc plating allows for decades of rust free service. The sluice body is approximately 24 inches long, 7 inches wide and 2 1/2 inches deep. The unique riffle system is 15 inches long with 5 riffles. Also features a flared intake to bring more water thus more washing action through the sluice box. The entire box weighs only 3.1 pounds.
