Free Sluice Box Plans Wanted - get'er here!

This website http://sluiceboxplans.net/ advertises free sluice box plans if you provide an email address. If I know water is running wherever I go in Arizona, I bring a pan and a sluice; otherwise it's just a dry washer. You can get more promising material with a sluice than only a pan. The following is a quote from Dave McCracken, "The water flow should be just enough to keep the concentrating action going behind each riffle, yet not so much that the riffles are being swept clean."
