How Metal Detectors Work and Their Benefits
Introduction
A metal detector is a device used to detect the presence of metals. The first use of such a device was in the late nineteenth century when it was used on ships to find lost items. Since then, metal detectors have become more sophisticated and are now used in many different situations around for example check out these metal detectors for sale in NZ.

The device detects the presence of metals.
A metal detector is a device that detects the presence of metals using electromagnetic induction. When a conductive metal passes through the magnetic field, eddy currents are induced in the conductor, and this can be detected by the metal detector. The more powerful the magnet in your metal detector, the more likely it is that you will find something!
The device was invented by archaeologist Sir William Golding in 1806 who used it to help him locate buried ancient relics and other valuables during his excavations at Pompeii.
It can detect metals like lead and steel.
The metal detector can detect all kinds of metals, even if they are buried deep inside the ground. It can detect lead, steel, and other metals that are less than an inch below the surface. It can also detect gold, silver, and copper which need to be at least three inches below the surface before you can see them with a metal detector.
The machine is so sensitive that it can even pick up non-metals like glass, wood, or plastic.
Metal detectors can help in locating underground pipes, cables, and other things.
Metal detectors are used to find lost items, buried treasure, and even dangerous objects like land mines. Metal detectors work by sending an electric current through the coil of wire. As the metal object is passed over the coil of wire, it generates a magnetic field that deflects/changes the direction of the flow of electrical current. This causes a change in voltage output from the detector’s circuitry resulting in an audio response from headphones or speakers depending on the type of metal detector used for detecting metals on land. The graph below shows how much voltage varies according to frequency when using different coils:
Metal detectors can be divided into two types – Conventional and Pulse induction – based on their working principle
It has many different uses.
Metal detectors have many uses. They can be used to detect metal objects in the ground, inside walls, and even buried underground.
They have been used for finding buried treasure and coins, but they are also useful in finding other items that may be lost or hidden away. For example, they can help you find a missing ring that fell off your finger while gardening or look for something valuable like jewelry that might have been stolen from an apartment.
Various kinds of metal detectors are used for various purposes.
- There are several types of metal detectors available in the market. These include:
- Handheld metal detectors: These are used for detecting metals like gold, silver, and copper in remote areas where digging is not possible or time-consuming. These can be used at home as well as on a treasure hunt.
- Waterproof or underwater metal detectors: These are large machines that have powerful coils which detect the presence of metals even beneath the surface of water bodies such as ponds, rivers, and lakes. They have been used by archeologists who want to find out if there were any hidden treasures beneath their feet when they excavate a site.
Conclusion
Metal detectors are used for various purposes. They can be used to find buried treasure, lost idols, or even pipes and cables. The device detects the presence of metals and helps in locating these hidden objects.
