A lot of things are called metal detectors and they have no resemblance to each other. Some are meant to detect water pipes several feet underground. Some are tuned to detect very small amounts of any metal, while others are not so sensitive but will tell you what kind of metal. Some only detect general mineralization like from an airplane or something. The answer depends on what you have there.
