Have you ever heard that the first metal detector was created by a German immigrant? Yes, Dr Fischer immigrated to California and started the whole gold-finding story. he gave his gift to the world in 1925. compared to the ones we have today, this metal detector was very simple, but still, a good starting point considering he made it into his garage. He started showing it to people and they became interested. Everyone wanted to have one. The devices we have today are far more complicated and advanced, have more features and are efficient in their work.
