The metal detector is a tool familiar to many adventurers and tricky cases. He is also often shown in films. Most often, a metal detector is presented as a long stick with a round disc at one end and a screen at the other. In books and films, it is used to search for gold or treasures.
Everything in life is much more prosaic. The metal detector is used by builders in the reconstruction of old houses. With its help, it is possible to detect pipes, electrical cables. The tool is also used by the military, divers, archaeologists to search for various objects. Entertainment for the sake of it too. There are as many purposes as there are types of devices. Because of this variety, it's not easy to figure out which metal detector is best to buy.

Do not bother with engineering terms and diagrams. A metal detector is a tricky thing. But there are several parts that are present in each model. These include:
On some models, there is a middle shaft between the lower and upper shaft. This part has mechanisms for adjusting the height of the device.
The armrest made of polymer material makes it easier to work with the metal detector. For the same purpose, as well as for a secure hold, the device is equipped with a handle made of porous material. The task of the control unit is to process the information supplied by the coil. Through it, the user can configure the modes. The control unit is of two types:
Modern popular models of metal detectors are distinguished by their reliability, compactness and excellent performance.
To find what you are looking for faster, you need to understand how the device works. The metal detector can detect both moving and non-moving objects at different depths. It happens as follows:
The accuracy of a metal detector depends on its functionality. An amateur model, assembled in his father's garage, will find a rusty plow in the field. But a professional tool is capable of much greater feats. Advanced models come with VFLEX technology, so they better recognize objects.
One has only to start looking on the Internet or in traditional stores, so you can come across a metal detector for finding gold, distinguishing metals or designed to detect specific objects. And these are not all types of the device.
But before delving into specialization and certainly making mistakes when choosing, it is worth learning about the three main types of device.
When accuracy of detection is of paramount importance, a pinpointer is used. The tool is a "shovel" or "rod". He determines at what depth the object is located with an accuracy of 1-2 cm. But his strength is not enough for a large area, so the coverage is small. Exactly the opposite is true for a metal detector of traditional design. It "sweeps" a large area, but the accuracy is about 20-30 cm.
What to look for when buying a metal detector is its specificity of action. As expected, each variety has its own strengths and weaknesses.
A professional metal detector detects several types of metals and is equipped with different search methods.
New items constantly appear on sale.Manufacturers are trying to improve the device, make it more accurate and even easier to use. But do not rush to find out which company is better to believe and how much the model costs. First, you need to understand what this or that type is suitable for.
For the military, a special metal detector has been developed that looks for mines. There is also an industrial grade that is used to detect metal in other materials. A separate type is a magnetometer. His task is to find iron and other ferromagnetic metals.
You can argue for a long time how to choose a tool, and finally get confused in the range. When there is too much information, it remains to look at the rating of high-quality metal detectors, where a device will be found for a specific task, or two or three at once.
American developers have come up with a metal detector that is both easy to use and useful when looking for treasures. This device is perfect for a beginner! With it, you will be able to find small objects (for example, coins) at a depth of 20 cm or large objects hidden 1 m below the ground.
The device is often copied. The Chinese counterpart costs two or even three times cheaper. The novice treasure hunter will quickly master the assembly and management. When going into the field, you should bring extra batteries with you. The tool is quite hardy, but it cannot work forever. Therefore, shrunken food is the main nuisance that lies in wait for the user.

A legend among metal detectors that falls slightly short of a professional tool. It is used by builders, prospectors, treasure hunters and geologists. The device will detect metals at a depth of 6 meters.
The device is equipped with two search boxes. Since it operates at low frequencies, it is ineffective in wetlands. The detection rate is 12.5 kHz. In the device, you can manually adjust the ground balance, sensitivity level. With them, you will be able to explore a large area at an accelerated pace. The search for metals is performed in a statistical and dynamic mode.
Average price: 54,250 rubles.
The standard device is always chosen by coin hunters. The instrument is endowed with 4 modes, multi-frequency transmission (from 1.5 kHz -100 kHz). It differs in simple operation, but due to its heavy weight, it will not be possible to explore the territory for a long time with it.

It is not enough to find a metal detector suitable for the price! He should be useful, at least help in finding treasures in his own area.What the purpose of the device will be depends largely on its functions.
First of all, you should pay attention to the coil, which is found in budget mono or DoubleD models - in more advanced ones. The maximum detection depth directly depends on its diameter. The parameter ranges from 9 to 12 inches.
How accurately an object will be identified depends on discrimination. The device operates at either one or more frequencies. How often to choose devices depends on what you want to find.
The device must have ground balancing to determine the degree of soil contamination and its structure.
Weight, control box placement, digital detection or built-in speaker are also worth considering when choosing.
For gold prospecting it should be used with ZVT technology. The RF device is designed for deep search. FBS technology implies the simultaneous use of 28 frequencies in the range from 5 kHz to 100 kHz.
The best metal detector manufacturers are Fisher, MineLab, Garrett, Whites and Aka. The popularity of the models of these brands is due to the high quality and good performance, even if it is an inexpensive device. Whether it is a construction device or a small amateur device, you need to choose the unit that will bring pleasure, and will not be gathering dust in the closet.
