Rick, Dr. Sluice, joined Randy and I for some fun. Rick has an unusual way to run a sluice. It really works great. I've seen days that he has gotton more gold with his sluice then we did with our 4" dredges.
Here he is all set up.
Taking a little break while the water does it's work.
He has a special classifier right on the front of the sluice. Also, notice the rock try alowwing use of smaller rocks to hold it in place. Sometimes there just aren't any correct shaped rocks to span the sluice.
You just load it up with a shovel full and then splash water over it using the shovel to wash the sand and the gold through.
After the fines are washed through, remove the classifier to dump it. While it is off, you can inspect the rubber mat for the gold that shovel produced. Very handy for sampling
Checking the mat.
