Self Locking Backpacking Stream Sluice
Unfold Unit so sections are past center to engage locks.
Unscrew wing nuts from both sides of wide mouth feeder.
Place feeder on end of section 1 and fasten with screws and wing nuts provided.
Your unit is now fully assembled.
For unit to operate properly, the feeder must be 4 inches higher than the back end.
Place unit in shallow water no more than height of sides.
Place shovelful of material in feeder on top of mat. Material should immediately start flowing down sluice box. 50% of material is being trapped behind riffles while the other 50% washes down stream. (This is the proper flow & angle when this is achieved).
Note: Water flow is too slow if unit fills with sand and gravel – you then must increase your water flow, angle, or both to achieve the 50% being trapped and the 50% going down stream.
