Drywashers are quite similar to highbankers but they do not use water. A Drywasher uses moving air through the material to blow off the light overburden, and then a shaking action to move the larger material out of the sluice. They are perfect for treasure hunting in arid and desert areas. Prospect for Treasure offers a great selection of drywashers from Gold Buddy that will be perfect for you. These drywashers have the largest capacity of all drywashers manufactured in the United States and also feature aluminum hoppers and recovery boxes, blowers and hoses, a uni-bearing shaker assembly, and much more. If you are looking for the best drywashers, we have them here!
