We have listed several videos below in which Doc shows how to use the stream sluice. It’s better than writing 5 pages.
There are two mats, reg / high flow and a low flow mat. We suggest you PLAY with both to see which works best for your area and stream flow.
TUNING YOUR SLUICE
When setting up a stream sluice there are WAY TOO MANY FACTORS to determine a SET PITCH or angle. You need to play with it and adjust it based on what you see in the mats. While they should contain SOME black sands and may even SOME lights… they should not fill up… nor should the BLOW OUT.
