How to choose a metal detector
To find the most suitable metal detector, you need to decide how the equipment will be operated. The simplest models are suitable for detecting objects at a short distance in the absence of interference. Expensive technology can boast a wide range of functions, so it can be called universal.

Metal detectors can be conventionally divided into several groups: ground (simple, semi-professional and professional), gold diggers, underwater, deep, arched, manual and pinpointers.

Simple ground metal detectors

Devices of this type are considered to be among the cheapest and least functional. Their purpose is to detect metal objects at a small distance. Rarely is the equipment able to determine the type of material or depth of its laying. The number of frequencies does not exceed two. The efficiency of the work depends on the type of soil and the size of the object. It’s not going to work out deeper than 70 centimetres.

Among the advantages of such technology can be highlighted minimum cost, a huge range of models and a small weight. Almost everyone will be able to buy a simple metal detector, though the scope of its application is very narrow. Weaknesses are reduced to low power, limited functionality, depending on many factors. Devices are very susceptible to noise and interference, which means they can cause malfunctions.

Semi-professional metal detectors

The equipment is suitable for people who know how to handle metal detectors. The cost of technology is much higher than the price of simple devices. A distinctive feature of functioning can be called the use of a large number of frequencies at the same time. Due to this, the radiation is more informative. The signal about the discovery of the object is not only sound, but also displayed on the display. The graphical interface provides information about material discrimination, i.e. “black” or “colored” metal found. The equipment is enough to search for items at depths of up to 1-1.5 meters.

The functionality and efficiency of this equipment is better than that of simple ground metal detectors. It is also useful to be able to determine the type of material. Of the shortcomings can be distinguished by the increased cost of technology and complexity in its development. Not every beginner will be able to figure out how to use it.

Professional ground metal detectors

Multifunctional and expensive metal detectors. designed for real professionals to search for iron objects. The device has a microprocessor and an incredible set of automatic and manual settings. Several modes of operation will help to adapt to soil and environmental conditions. The search is done with multi-band discrimination at once in a wide range of frequencies. The equipment has the ability to find the “colored” metal that lies next to the “black”. Signals are sent simultaneously in sound, graphic and digital formats. The screen displays data on the depth of the object, its type, the assumed size. Power is enough to detect metal at a distance of two meters or more.

The advantages of such metal detectors are incredible. They are considered to be the most reliable and practical. The disadvantages of technology can be called complexity in mastering, high cost, significant weight of some models. Such devices are suitable only for qualified professionals.

Gold diggers

In fact, it is an analogue of professional detectors. that are well-established to find even the minimum gold content in the soil. The technique is customized to frequencies that are perfect for detecting expensive metal. The depth of the objects can be up to two meters. If desired, the hardware can be reclassified to look for other types of material.

Of the advantages of these devices, it is worth noting the high efficiency of the search specifically gold. It will be quite difficult to set up professional equipment for such a task. Disadvantages of gold prospectors have a decent amount of equipment expensive, and the possibilities of its use are very limited. Serious interference in the search creates foil and aluminum, which are reflected on the display of the device in the same way as gold. It is almost impossible to detect a piece of metal even at a shallow depth.

Underwater metal detectors

Such metal detectors are not much visually different from professional ones. The difference is that they are designed to search in a water environment. Accordingly, the equipment is set up to ignore the interference that the liquid creates. The body of the device is airtight, which means that it can be submerged under water. The technique is necessary to detect objects at the bottom of the reservoirs. The signals are only sound. The depth of the search depends on the environment.

Highly specialized metal detectors that are expensive and provide excellent efficiency in the search for items underwater. Special skills are not required to properly operate the equipment. The drawbacks of the devices are high cost, limited functionality and dependence on environmental conditions.

Deep metal detectors

These metal detectors are often used for industrial purposes. From the name itself it is clear that they allow to detect objects at a considerable depth, which in some cases can exceed six meters. It all depends on the size of the object. Unfortunately, it will not be possible to discriminate, so to understand what metal was found, you will have to dig it up. The devices are actively used in the laying of engineering communications, as well as on excavation sites in the areas of world war.

A clear advantage of technology is the ability to find objects at considerable depth. The power is enough to accurately determine the distance to the object, its size, in which direction it lies. High cost, inability to determine the type of material and inability to find objects located at a distance of 5-10 centimeters from the surface of the earth. are considered the disadvantages of such devices.

Arched metal detectors

They are also called framed because they are shaped like a door box. Expensive, but very accurate and reliable equipment. The equipment is installed stationary in crowded places, airports, military facilities. The power of the drive is enough to detect even a miniature metal object. The devices even react to the fragments left in the human body after the grenade exploded. Security structures are very appreciative of arched metal detectors.

Some models can determine the type of material, which greatly expands the functionality of the device. The list of advantages of technology does not end there. Equipment makes it possible to secure any object. Of the disadvantages it is necessary to highlight the high cost, complexity of the setting, stationary.

Manual metal detectors

Such detectors meet in the hands of representatives of the law, guards, military. The devices are small in size and have a wide range of supported frequencies. Accordingly, they allow to detect even needles on the human body. Some of the most common and affordable metal detectors.

Compactness, relatively low cost and the ability to detect even miniature items are advantages of such devices. The drawbacks are represented by the limited functionality and dependence of the device on external interference. In addition, if the device is configured to detect small objects, the background from large will be ignored.


Small metal detectors capable of detecting objects at a distance of no more than 5 centimeters. Most often they are used to search for wiring in the walls or during excavations on the battlefields. A distinctive feature of this technique is the accuracy of determining the location of the object up to millimeters.

The advantages of pinpointers: accuracy, minimum cost, small sizes. The disadvantages of the devices are reduced to the lack of ability to produce discrimination, weak power, small depth of metal detection.
