The 19A1 Sluice from Prospectors Choice is a larger sized more productive Alluvial Sluice Box. It employs the same concept as the 15A2, with some improvements. The Alluvial Sluice bottom has a boiler plate, or ribbed slick plate. This allows for more mixing of material with water, and extra gold capturing surface. Below the boiler plate is ribbed matting to further capture the finest gold particles. It comes with the Tsunami t500 pump and hanger, wire, and all necessary hardware for mounting the sluice to a standard 5 gallon bucket. Each Measures 21″ x 9″ x 2″ Overall.
