FAQs

What is a metal detector?
A metal detector is a portable electronic device that uses electromagnetic fields to locate metal objects buried underground.

How does a metal detector work?
Metal detectors work based on the principle of electromagnetic induction. They emit a magnetic field through a coil, and when the field encounters a metal object, it induces a secondary magnetic field in the metal. This secondary magnetic field is then detected by the metal detector, alerting the user to the presence of metal.

Who invented the first metal detector?
The first practical metal detector was invented by Alexander Graham Bell in 1881. However, it was primarily used for locating bullets in President James Garfield’s body after he was shot. The first metal detector specifically designed for treasure hunting and hobbyist use was patented by Gerhard Fischer in 1931.

Are metal detectors commonly used today?
Yes, metal detectors are commonly used today in a variety of applications. They are widely used in security screening at airports, schools, and public events to detect weapons or other prohibited items. They are also popular among hobbyists for treasure hunting, including searching for coins, jewelry, and relics.

Can metal detectors detect all types of metal?
Metal detectors can detect most types of metal, including ferrous (iron-based) metals like iron and steel, as well as non-ferrous metals like gold, silver, and copper. However, some metals, such as aluminum or brass, may not be easily detected depending on their size and composition.

Can metal detectors be used underwater?
Yes, there are metal detectors specifically designed for use underwater. These waterproof detectors are commonly used by beachcombers and underwater treasure hunters to search for lost jewelry and other valuable items in shallow water or on the ocean floor.

Can metal detectors detect objects deeper underground?
The depth at which a metal detector can detect objects depends on various factors, including the size and composition of the object, as well as the sensitivity and technology of the detector itself. In general, most hobbyist metal detectors can detect small objects like coins or jewelry up to a depth of about 6-8 inches, while larger objects like buried treasure caches can be detected at greater depths, sometimes several feet deep.
