Metal detectors

Detecting metals underground requires devices with advanced techniques with different search systems that suit all metal targets, whether they are archaeological treasures or metal pieces and these devices are metal detectors.

Some of these devices are designed to detect specific metals, such as gold, and some can detect a wide range of metals.

Metal detectors
Metal detectors play an essential role in daily life to the point that they have become essential in many industries, especially for security agencies to combat crimes, as well as for treasure-hunting and prospecting institutions. These devices have undergone continuous development since their invention, and this has made them used in many fields.

How metal detectors work?

How metal detectors work is not known to many, even some professionals. There are scientific principles on which these devices are based. The most prominent of which is that metal has magnetic properties that differ from the parts of the soil surrounding it.

These devices rely on electrical current in a wire coil present in the device, which produces an electromagnetic field that spreads over a wide range in the soil.

When a metal object is present, it causes noticeable changes in the magnetic field lines, causing many electrical signals to appear, and the device recognizes them and issues signals indicating the presence of the metal.

There are also some devices used in metal detection that can determine the depth of a piece of metal in the ground. The depth is displayed on the device's digital screen to help extract the piece very easily.
