just wondering what others think on this other set up for my sluice (a52 keene) its a rubber riffle matt from poineer mining in auburn , top section moss with v matting under ! i have used it does work well ! and cleanup is super quick !
It works fine The riffles really depend on the water flow where you are at each time. I have used that mat and lots of others and it does do the job. But the rubber should be at the top because it's designed for easy clean up.
