So this new economy actually is a lot like the old economy- you know, the era of treasure hunting. With the actual unemployment rate over 25%, more and more people are investing in garretts metal detectors and looking for gold, artifacts, coins, and precious metals under the ground. Beaches are an excellent place to use your metal detector. Be sure to research your state’s law about metal detector use. Generally speaking all public beaches and land is fine, but there are some exceptions based on your state.
