4 color options: black, blue, green, and a blue variant; diameter 38 cm (15 inches). Key benefits Efficient gold particle recovery: designed to collect all sizes of gold particles without losing fine particles, improving overall yield in field prospecting. Durable and lightweight: molded from ABS plastic for lightweight handling, rust resistance, and longterm durability; floats in water. Improved separation: features a shallow side wall to enhance separation of gold from other heavy minerals, similar in function to a sluice box. Practical sizing: a 38 cm (15 inch) diameter provides a broad catching surface while remaining portable for field use. Specifications and construction Color options: black, blue, green, and blue variant. Diameter: 38 cm (15 inches). Material: ABS plastic (lightweight, rust, durable). Design: shallow side wall aids in separating gold from other heavy minerals. Use scenarios River prospecting: deploy in a shallow river or stream to process sediment during field prospecting and recover fine gold particles. Beach placer work: use in coastal or shoreline channels where fine gold concentrates are present. Hobbyist demonstrations: suitable for educational demos or casual gold recovery activities in outdoor settings. Functionality and performance The combination of a broad catching surface, buoyant material, and a sluicelike separation design helps maximize gold recovery while minimizing material loss. Lightweight and buoyant construction makes it easy to transport and use in varied water conditions without added equipment beyond standard field gear.
