Sluices don't need to be expensive or complex. Some form of matting with expanded mesh on top will pretty much suffice in most settings. Perhaps a riffle or two to catch bigger nuggets. Also you have to have your flow of water right....
And now....On sandy beaches and muddy soil, rings and coins await my coil!

Find some old square sided guttering, cut out a rectangle of old carpet, either use a strip of expanded metal or if you are really cheap you cut down a plastic bread crate (which works suprisingly well!), tie it all together with a bolt, a couple of penny washers and a wing nut.

It works well, you can leave it in the bush without fear of it being nicked, and if it does go missing then you probably have enough offcut left from the first one to fashion up a new improved version.



Those $60 plastic sluices you mention that you found on trademe are best suited to being used as a clean up sluice, somewhere where there is a lot of black sand which takes time to seperate the gold away from, or for someone who operates a dredge where you end up with a lot of concentrate that would take several pans and far to long to get through. They will lose gold if you used them as a river sluice without first classifying the material down to something impractically small, you need something with a mat and either riffles or expanded metal
