For those of you that have problems with lots of black sand, this might help..
Like everyone else I got tired of fighting all the black sand, I tried most of the
other concentrators only to find it still took hours,so I built one of these,it really
cut down on the work on the cons for me. Sometimes I pan out the light sand and sometimes
not, the black dries lots faster by its self, and the lights are easy to pan anyway.
The first two pics are of the seperator, the next three pics are what I started with
and how it seperated out.My 4" sluice is seperated into 3 pieces,so this is 1 third of
the cons, it took less than 10 minutes to seperate this third. I have a limited number
of these if anyone is interested... $75
