If the metal is conductive, then the chances a detector will find them are high. Metals That Metal Detectors Can Easily Findįerrous metals are the easiest for metal detectors to find due to their magnetic properties. Other items that metal detectors won’t be able to locate include: Stainless steel has low magnetic permeability, which means it does not produce a signal strong enough to be detected. Metal detectors have a tough time detecting metals like stainless steel, which have very poor electrical conductivity. This means that they send out electromagnetic fields and listen for any waves that come back from items with electrical conductivity. Metal detectors work on electromagnetism. However, metal detectors can’t find everything that lies underground. Metal detectors are electronic devices that use a large coil of wire, known as a transmit coil, and a second coil of wire, also called a receive coil, that alerts you to the presence of buried metals by emitting a sound. Read on to learn what metal detectors are, how they work, and metals that they will not be able to detect. While they may seem like a full-proof way to find valuable treasures lying underground, they do have their limitations. If you’ve ever had an interest in treasure hunting, you’ve likely seen metal detectors before. ![]()
