how to build a gold detector? - RC Groups

2008-7-19  You can use a standard metal detector to find metals, but to differentiate between gold and other metals you'll have to use another method. More than likely anything you come up with will involve take a sample of a material and performing tests on it. Don't expect to find a magic wand that lights up when you point it at gold.
