Operational characteristics and capabilities of metal detectors

A standard metal detector is a control unit and a coil that generates an electromagnetic field. The device requires a source of electrical energy to operate. The battery (accumulator) or battery acts as a power source. As soon as a good metal detector finds an object, the information immediately goes to the control unit. Its task is to correctly assess the physical parameters of the discovered thing. The performance of the unit depends on the degree of its sensitivity and on the correctness of the settings made.

User information system

Using the device does not require professional training. It is enough to keep in mind a few rules. The first is a varied tonality that sounds as you approach the goal. The really best metal detector for finding gold makes a lower sound when a person is near, but not too close to the desired target. If the sound has become really high, then it is worth stopping and seeing what the device found. In addition to the degree of remoteness, the size of the object you are looking for affects the height of the sound. The larger it is, the more substantial the sound will be. Separately, it is worth dwelling on the issue of searching for small objects that lie at great depths. In such a situation, you will have to spend more time, because even sensitive coils will not always cope with the task.

Operational characteristics and capabilities of metal detectors

In the XNUMXst century, truly functional models lead the rating of metal detectors. At the dawn of the era of searching for metal objects, a person was forced to rely more on his instinct than on the readings of the device. Today the situation has changed for the better. Many models are equipped with an information screen that provides the necessary information. Even a beginner will have no problems.

Device Frequency

When choosing the best metal detector, always study the performance of the device. Attention is paid to the frequency of the gadget, which largely determines the depth of penetration of the "search beam". Low-frequency models include those whose description indicates only from 5 to 7 kHz. They will cope with the search only for large-sized objects. Simply put, they will find something large at a considerable depth, but they will not find something very shallow near the surface. If a person needs good metal detectors to detect coins or nuggets, then high-frequency modifications are indispensable. The instructions should indicate that they operate in the range from 18 to 100 kHz.

Coil Physical Characteristics

As soon as the potential buyer has figured out the frequency of the device, they proceed to consider the parameters of the coil. For example, deep modifications use a mono or concentric coil. Low-frequency modifications work at a shallower depth, but at the same time cover a large area. Among other advantages of the mentioned devices is the ability to find objects located under a layer of highly mineralized soil.

How to cut off garbage and other unnecessary finds

Manufacturers are not sitting idle, equipping popular metal detectors with new features. This is an option called discrimination. It is necessary in order to timely exclude foreign objects from the search results, for example, beer cans. To do this, simply select the appropriate options in the settings. Another very useful option is called pin point. In this case, the user receives the most accurate information about the localization of the object under the earth layer. Thanks to this, the excavations will not be delayed. An option called "ground balance" is responsible for the degree of sensitivity of the device. When deciding which inexpensive metal detector to buy, it is important to pay special attention to it. If the work is to be done on soil with a high degree of mineralization, then an appropriate sensitivity level is set.

Harder or lighter

The best metal detectors in the world with a certain weight are presented on the market. Once a person has selected several potential objects for purchase, they should be held in their hands. It is important to understand how convenient they are to use. You should not take too heavy seekers, otherwise, after a few minutes of work, you will have to take a forced break. In addition to choosing based on the weight of the unit, you can purchase the best metal detector for working on the surface of the earth and under the water surface. In the latter case, we are talking about 100% hermetic modifications. Closed devices are completely enclosed devices. The user can easily hear the sounds emitted by the unit as they approach the target. Most closed models designed for underwater use have a headphone connection option.

Rational use of funds

A person who chooses which is the best metal detector to buy should not go to extremes. This device cannot be considered as a "jewel magnet". It only helps to find them, but does not guarantee their finding. Much depends on choosing the right place to use the unit, as well as on the ability to use it. The emphasis is on the location where there were parking lots of people. At the selection stage, a conditional terms of reference (TOR) is formed, in which the following parameters are fixed:

  • coil type;
  • work frequency;
  • maximum depth of detection of objects;
  • ground balance setting mode;
  • weight of the device.

The more specifics will be in the TOR, the better. Separately, you should pay attention to the reviews of other users. As soon as a list of several models is formed that a person considers as possible objects for purchase, they try to find as much information as possible about each of them. Reviews are read on several portals to get an objective view.

How to make a bargain purchase

The list of top 10 metal detectors includes multifunctional and at the same time durable models. Be sure to check the quality of the body, which should not collapse too quickly in case of minor mechanical damage. Do not disregard the degree of complexity of the menu with the settings. When deciding what a good metal detector is, it is important to know in advance as much as possible all the data. For example, it will be difficult for a beginner to understand a large set of options, and a professional will be disappointed with a menu that is too simple. Be sure to take into account the ultimate purpose of using the device and the frequency with which it is planned to pick it up.

For a one-time amateur use, a budget model is suitable. It is inexpensive, but it will help you find metal objects on the beach. If the user plans to professionally engage in ground or underwater searches, then a more advanced modification is indispensable. Regardless of the choice, shopping is sent to an authorized store. The manager will provide comprehensive information about each model. In addition, you can choose among a large number of models. The warranty is a nice bonus.
