Metal and gold detectors always enable us to search for metals and gold underground with great efficiency. They are widely used in a large number of scientific and applied fields. Therefore, many people want to know How Metal Detectors Work.
In this article, we provide you with accurate details to know How Metal Detectors Work to get a unique experience in detecting gold and metals
Metal Detectors
Metal detectors are devices that are manufactured on a scientific basis to search for metals and gold underground in various environments and terrains. They are relied upon in many different applications and uses, most notably detecting gold in mines, as well as being used in airports for safety and protection purposes for passengers and travelers.
There are a large number of companies that manufacture these devices with advanced specifications and technologies. These devices are available in different types to suit all categories of users, whether amateurs or professionals. Gold Master International Company specializes in providing these devices at competitive prices to suit all categories and different budgets. In the following lines, we will learn How Metal Detectors Work.
How Metal Detectors Work
To know How Metal Detectors Work, it should be noted that metal and gold detectors depend on a fixed scientific principle, which is electromagnetic induction. It depends on the passage of electricity through some wires in the device, which generates an electromagnetic field. This magnetic field heads towards the ground to a specific depth that varies from one device to another, and when it collides with any piece of metal, the device senses this piece. It sends alerts to the user to indicate the location of this piece of metal.
Types of Metal Detectors
After we know How Metal Detectors Work, we will talk about the types of metal detectors, as follows:
- Raw gold detectors: These devices are used by a large number of beginners and amateurs to detect raw gold. Any type of metal can be detected, even if these treasures are thousands of years old.
- Sensor metal detectors: These devices are capable of detecting gold for long distances and great depths underground. Suitable for all types of soil, including sandy soil.
- Electromagnetic gold detectors: These devices are used to detect metals and gold close to the surface of the earth because they do not reach long depths underground.

Components of metal detectors
Metal detectors consist of a set of main components that integrate with each other to achieve the best result in detecting gold and metals. The most prominent of these components are:
- Control box: This part is the main part of the device as it contains the battery and control keys in addition to the device processor, screen and internal speakers.
- Search coil: It is the lowest part of the device that is used by moving it on the surface of the ground as it contains a set of electrical wires that generate a magnetic field.
- Device arm: It is considered the structure of the metal detector as all components and other parts are connected to it and its length can be controlled according to each user.
- Device stabilizer: This part makes the device comfortable while using it as the arm can be supported on it, and it reduces vibration and balances the device during the process of searching for metals.
How to use a metal detector
How Metal Detectors Work
In order to be able to use a metal detector with complete care to get great results, you must follow a set of steps with comprehensive professionalism. These steps are as follows:
- Choose the right place to detect metals. There are many places where you can detect, such as coastal beaches, gold mines, or areas famous for the presence of gold stones such as quartz.
- Prepare the equipment for detecting metals, such as drilling tools to extract gold and metals after detection, as well as headphones to hear the device’s signals.
- Make sure that the search in the place you have chosen is legal and there are no problems with the competent authorities. There are many places where gold detection is prohibited because they are considered prohibited places.
- Fully charge the device’s battery, then put it in the device and then make sure that the device is working efficiently before moving to the place where you want to detect metals.
- After arriving at the place, turn on the device by pressing its power button so that the device starts working after a few seconds.
- Test the gold detector before starting by bringing a piece of metal and passing the device over it, and when you hear audio signals, this indicates that the device is working efficiently.
- After turning on the device, pass the search coil back and forth on the ground so that the search coil is not attached to the ground but is 1.5 inches away from the ground.
- When you hear any signals coming from the device, determine the area where you heard the signals and then use the digging tools to extract the metal piece in it.

How does a metal detector actually work?
Metal detectors work by generating an electric current in the search coil, this current causes a magnetic field to be generated. The magnetic field passes through the ground, and when there is a piece of metal, interference occurs in the electromagnetic signals and this change is read in the device.
This change in the electromagnetic signals emitted by the piece of metal is converted into audio signals that are heard in the device’s speakers. There are some devices that rely on a digital screen where the search results appear on the screen and through which all data related to the metal pieces can be determined, whether the depth or the exact location, and this is the answer to the question How Metal Detectors Work.
What metals cannot be detected by a metal detector?
There are a number of metals that a metal detector cannot detect, such as ungalvanized steel and titanium, because the electrical conductivity of these metals is weak and therefore metal detectors cannot easily identify them.
