Modular Drop Riffle Sluice (Small)

A modular drop riffle sluice with a wide flare (30cm/12in) for better water flow, and a V ribbed section up top so you can see when you're on the gold. Approx 15cm/6in wide riffle section.

At a minimum I would use three riffle section as show in the attached pictures. Whether or not you use the ribbe
