Sluice boxes are a great way to seperate the aggerate/wast from the heavy metals(Gold hopefully) The only better ways are toxic and very heavly regulated. Even sluice boxes are regulated in most states.. The laws can be bizzare... Check with you local state agency and rock hounds.. This can be fun and alot of work. A nice hobby.. There are many resources on the net on how to build one. I think the best way to get started is to find a town where panning for gold is mostly a tourist attraction and hang out for a day.. The local stores will have many small books on the subject. Do some research.. and deceide if you would like to give it a try.. Panning comes before the sluice box. Learn to Pan first.. Ps. Buy some good rock shoes.. Bare feet is dnagerous.. ouch..
