About Metal Detectors

Metal detectors are handheld devices that are designed to use electromagnetism to detect metal where it may not be seen. It is used in many military and industrial purposes. They are also recreational tools for small-time treasure hunters and hobbyists. Having been around since the 1930s, the metal detector was a milestone in electronic development and continues to be used to this day.

Identification

Metal detectors are very easy to identify, though some may have more features than others. They have a handle at one end of a long pole, often with a computer attachment (in modern detectors) and a rounded electromagnet at the other end.

Function

When powered on, the metal detector is run across the ground or the object being scanned. Electromagnetic rays bounce off any metal and are sent back to the detector, which alerts the user to the presence of the metal via sounds.

Significance

Metal detectors have long been used by hobbyists and archaeologists to find buried treasure or objects. The military has an important use for metal detectors, which help soldiers find dangerous land mines.

Features

Modern metal detectors feature an array of computer systems that refine the detection capabilities of the device. It helps the metal detector and the user change the sensitivity of the detector, as well as the depth and the range of the device.

Potential

The future of metal detectors holds much lighter devices with simpler designs. They will have the same depth and range while being easier to handle by a person.
