This dream mat sheet/tile measures 406mm wide x 1219mm long and is specially designed for suction dredging. This particular sheet fits most traditional 4″ sluices from the big commercial manufacturers without too much modification.
Throughput and clear times will vary with the material you are sucking up. Heavy gold rich sulphides obviously require more processing time to clear whilst light sands migrate extremely well.
