In Russian fairy tales, treasure is inextricably linkedan immortal hero named Koschey, so it is not surprising that one of the best metal detectors on the domestic market has a similar name. Although many users of expensive imported equipment consider it different, however, in the category “price-quality” “Koschey” (metal detector) is out of competition.
This article provides the readerthe opportunity to get closer to the wonderful treasure hunting device. Review, characteristics, setting, scheme and reviews of the owners will help the potential buyer quickly navigate the market for specialized equipment.
In fact, the connection of the metal detector with a fabulousthe character is not connected with hiding treasure and jewels, but with the first two letters of the names of the developers Yuri Kolokolov and Andrei Shchedrin. Two mechanical engineers have been known in the amateur radio environment for many years. They, in addition to the production of specialized equipment for the search for metal, earned credibility in instrument making.
Unlike foreign manufacturersmetal detectors, Russian scientists did not hide the principle of operation of the devices created by them and gave buyers the opportunity to change the technical characteristics of electronics. The metal detector circuit, a detailed description of the basic elements of construction and a complete guide to setting up are present in the usual instructions that come with the device. It is this attitude towards the future owner that attracts a large number of potential buyers to the device.
To search for metal objects on smalldepths and in the walls of old buildings is best suited inexpensive pulse device. Metal detector "Koschei-5I" worth about 5,000 rubles is able to interest buyers who acquire such a specific device for the first time.
All the functionality of this device is based onthe microcontroller and a small program, and the simplicity of the design allows the owner to make the revision on their own, improving the sensitivity of the device as needed. The principle of its operation is quite simple - the coil creates an electromagnetic field, which changes its characteristics when passing through metal objects. The microcontroller analyzes the initial signal with the final value and gives the result to the user.
Cheap metal detectors have one nastyfeature - the lack of a liquid crystal display. Naturally, the owner may have a lot of questions about the device settings, the program part is especially interesting, which, according to the manufacturer, is easily changeable.
As practice shows, the problem can be solvedin two ways: using a programmer and connecting the unit to a personal computer. If everything is simple and clear with the programming of the microcircuit, then there are obviously questions to the second method. In the operating instructions, the manufacturer not only described in detail the method of connecting the metal detector to the X4 port, but also indicated the adapter model that the user would need to solve the task. In fact, it is possible to connect not only a pulse metal detector to a computer, but also any other device that has an appropriate X4 interface.
It is clear that the term "metal" is actuallyNot only precious metals can hide, but also any garbage from steel or cast iron. Naturally, the treasure seeker will be interested in the possibility of determining only the treasure. It was for such purposes that the Koschei-20M metal detector was created. The peculiarity of this device is that the device can work in the frequency range of 4-10 kHz, and accordingly the user can control the power of the electric coil.
In addition to the basic characteristics required fortreasure hunt, the detector has a lot of useful and useless functions. First, the device is stitched at the program level, and on the official website of the manufacturer there is a choice of ready-made programs for its precise operation in different operating conditions. The manufacturer did not save on the sound indication, setting a full polyphony. But the ability to access the device by PIN-code causes only a smile on the face of the treasure hunter.
Do not expect the device to be impossible whenpurchase. No matter if it is expensive or cheap metal detectors, the user in any case will have to make fine tuning for each type of soil. Experts in this area recommend beginners to use the proven method with three coins (steel, bronze, gold), which must be individually buried to a depth of 20-30 centimeters.
Further, the whole is simple - leading the contour over the treasureand changing the frequency, you need to find out what sound indication corresponds to each metal to which the “Koschey” (metal detector) will react. As practice shows, at a frequency of 10 kilohertz noble metals made of gold and silver are perfectly detected, regardless of the depth. The sound produced by the device is quite melodic, easy to remember. But to search for metals based on copper, the frequency range is better shifted down (6-7 kHz).
Findings metal detector sometimes turn out to beso valuable that many owners of devices start to feel dizzy - they have a desire to buy a more powerful and expensive device for searching for treasure. Hurry to change the manufacturer is not worth it, the developers have something to surprise the buyer. On the basis of the device "Koschey-20M" there is an improved version of "Professional" with a Goliaf coil.
Keeping the appearance of the metal detector, includingcontrol panel and usability, the manufacturer managed to create a more powerful and sensitive device. First, the device is capable of separating precious metals from ferrous metals at great depths, even if they are in close proximity to each other. The second advantage is the ability to trigger the coil in the air, being above the ground at a distance of 5-10 centimeters.
Naturally, the Russian manufacturer should have at least one modification that can satisfy the wishes of even the most demanding customers.
The richer the functionality of the device, the greater itseffectiveness in finding treasures hidden under a small layer of earth. Naturally this attracts the attention of buyers to the metal detector "Koschey", whose price is in the range of 15-20 thousand rubles. True, few of the newbies know that in reality the whole functionality will not be used by the user, because the universal device copes with the task perfectly and in one mode of operation (this is a pulse search).
Therefore, before buying it is better to consult withexperts and for themselves decide what the buyer means by treasure. Some users need a device to search for lost jewelry near water bodies, while others are interested in finding war graves. Definitely: a serious approach should be taken to purchase an expensive device.
This is not to say that the manufacturer paid a lotattention to the appearance of the device. Rather, on the contrary, being fascinated by the functionality and efficiency of work, engineers forgot about the quality of the assembly. In the media, a lot of reviews regarding the cheap appearance, which has a metal detector. Comparing the device with similar foreign devices, a significant difference is noticeable not only in the quality of manufacturing, but also in ergonomics.
However, in the process of exploitation,The device can completely change from the owner. The simple design is reliable and practically defies deformations when falling or hitting. Therefore, it is up to the buyer to decide what is more important for him: to detect the findings with a metal detector that has external beauty, or one that has increased strength.
Domestic product is still interesting becausethe specialized markets of the Russian Federation, the owner will always be able to purchase the accessories and spare parts he needs for his device. And do not think that the choice is limited to chips and coils. On the shelves you can see: the housing for electronic components, brackets, handles, sensors, and even modified circuits of all devices.
As practice shows, the electronic circuitmetal detector and search coil are the most popular elements of the device. After all, they determine the effectiveness of the device. However, before buying spare parts, many experts recommend that the user first try to change the firmware of the metal detector, since it is often this action that allows you to more effectively configure the detector.
In its price category domesticThe device has almost no competitors. In their reviews, enthusiasts often compare the “Koschey” pulsed metal detector with a similar device, Fisher-2. It is not surprising that in all tests the Russian device wins, because, in fact, they are two completely different detectors, which simply ended up in the same price category.
So, "Fisher" is designed to search for smallproducts from non-ferrous metals and alloys at shallow depths (up to 30 cm). It has a low sensitive coil and does not work through the air. A "Koschey" (metal detector), on the contrary, is focused on large depths, large objects and is able to work in different frequency ranges. Comparison is better to produce according to the stated specifications, and not in the price category.
As practice shows, everything depends onuser requirements that he makes to the device. Even in the store, he can decide on the search for treasures and pick up the desired coil for the metal detector (the manufacturer provides such an opportunity). Therefore, it is not surprising that all the negative feedback from the owners is related to the work of the detector itself, which does not work with a specific soil.
There is another major flaw thathas a metal detector "Koschey". User feedback negatively describes the ease of setup and operation — mechanical buttons, separately programmable microcircuits, and control difficulties for a 21st century instrument are clearly overkill. On the other hand, any owner will be able to program the device for himself, which cannot be done with foreign analogues.
Leaves quite mixed feelings"Koschey" (metal detector) during the first acquaintance. A clearly flawed outwardly simple device a priori should not have such a huge functionality and demonstrate such attractive features. Therefore, recommendations to future owners will be as uncertain. Need 100% uptime, regardless of build quality and visual appeal? Metal detector "Koschey" will be the best purchase! But more demanding users need to look at the device in a completely different price category.
