This article is about deep metal detectors (or else they are called depths ).

How are deep metal detectors different from others?

The main task of deep metal detectors is to search for great depth of large targets.
At the same time, they are required to ignore small surface debris(metal).
This is what makes the depth finders different from all other mine detectors.

The task of discriminating ferrous metal from non-ferrous metal is not in front of them, although some have such a function. But it does not work 100%, because. with increasing depth, the complexity of metal identification increases. And the size of the target also does not allow us to conclude whether the target is colored or black (the target is very large, the electrical conductivity is high).

Therefore, many manufacturers do not include such functionality in their deep devices.

Overview of models of deep mine detectors

To date, there are many models of depths. Many of them are already outdated, some have just appeared on the metal detector market.
When choosing a downhole device (among other things), you need to pay attention to the sensors that the device can be equipped with. It's either a coil, or a frame, or both.

What is the difference between frame and reel depth probes?

A deep metal detector with a coil allows you to search in a limited space. In addition, it is easier to walk with a coil, because. it can be operated by one person and its size is smaller, which means it is more mobile.
But the frame allows you to cover a large area per unit of time and it is easier to ignore surface debris with it. And the depth with the frame is much higher than with the coil.

What is a depth frame?

This is a cable loop used as a sensing element. Usually at the junction there is an electronic circuit (hermetically filled with a compound).
The loop itself sits on some kind of rigid frame so that the latter gives the correct shape to the entire structure and so that it is possible to fervently carry (this created sensor) over the target without changing the geometry (sensor).
The frame is made from tubes. It can be collapsible or solid.
The loop itself can be passed both inside the tubes and outside.

Deep Hunter Golden Mask

For 2019, Golden Mask is releasing the Deep Hunter PRO-3 and Pro-3 SE models. This is a modern deep metal detector capable of working both with a frame and with a coil.
The device has a high search depth (with a frame of 125x125cm - a helmet - more than 3m) and good stability in operation.

Possible sensors:

  • Frame 125x125cm
  • Frame 180x180cm
  • Frame 300x300cm
  • Coils 20cm, 28x42cm, 42cm or 58cm
As we can see, the device is very attractive: depth + stability + a good selection of sensors.

In addition, the Deep Hunter PRO-3 can discriminate against metals (black - non-ferrous).
Deep Hunter Pro-3 SE has both automatic ground adjustment and manual. In addition, it has a wider range of adjustment for ignoring small targets.

Depth TM-808 Whites

Whites is well known for its metal detectors. The TM-808 is her coil-only depth gauge.

TM-808 has been in production for a long time. And today it is outdated.
If you do not touch on its search characteristics: search depth and stability, then TM has a big minus - coils that are subject to deformation.
When the search elements are deformed, the search depth disappears.
This is a significant drawback for field work conditions.

TM-808 has no discrimination. (but, as we said earlier, this is not very important for a deep diver)

The depth for the TM-808 is stated to be 4m (apparently for a tank). Specifications are not specified in the documentation. In practice, the depth is much more modest.

The TM-808 is considered to be good for use in confined spaces.

Depth Fisher Gemini-3

Fisher Labs has long mastered the production of a metal detector - Fisher Gemini-3, which uses as search elements - coils that are retracted into casings (if you recall the TM-808, it is precisely the fact that the Gemini-3 search elements are retracted into casings that protect the latter from deformation ).


The search characteristics of the Fisher Gemini-3 are similar to those of the TM-808. In general, the device is outdated.

Gemini-3 consists of 2 boxes (with sensors inside) spaced along the edges of the bar. This deep metal detector is worn on the shoulder or 2 boxes are used by 2 different people.

There is no discrimination in Gemini-3.

The depth for the Fisher Gemini-3 is stated in the documentation - 6m (probably for a tank). In practice, none of the search engines could confirm this depth.

Depth nozzle for GTI-2500 Garrett

The Garrett GTI-2500 metal detector has been in production for a long time. The device itself is out of date. However, the GTI-2500 can use a special depth nozzle, which makes it from a ground metal detector - deep.

The characteristics of the Garrett GTI-2500 depth probe are quite modest (more modest than those of the Gemini-3 and TM-808). They are not listed in the documentation.
However, search engines consider the 2500 deep metal detector to be more practical.

The GTI-2500 has 2 hard shell coils on a hard stem.

Detech SSP-5100

There is also such a deep mine detector as Detech SSP-5100. It is very similar to Deep Hunter PRO-3. (Exactly similar).
Deep Hunter has better characteristics, including stability.

And so SSP-5100 can use both frames and coils.

Detech SSP-5100 is very attractive in description. The spectrogram of the signal is displayed on the screen.
As you can see from the picture, the depth is up to 4m with a frame of 100x100cm.
But nothing is written in the instructions about the depth!

It remains only to try how it works in practice (watch user videos).

What is important to know when buying a deep metal detector?

When buying a deep mine detector, it is important to realistically evaluate the capabilities of the device. In practice, it often turns out that the characteristics from advertising booklets are not achieved.
In instructions, as a rule, data on the depth of detection is not written.

What you need from a deep metal detector:

  • variety of sensors (coils and frames)
  • stability
  • ignoring small debris
  • search depth
And taking into account the fact that the depth is not always the same as promised. And taking into account the fact that all the treasures were not buried too deep. Then the first 3 components are important from the depth specialist, and then the depth.

When searching for a war, the depth of the target can really reach up to 3-4 meters. Of course, in this case it is important. But subject to the stability of the device itself.

It is better to focus on videos made by users, in which they show the work of the depth finder and its depth of search.
Of course it won't maximum parameters. But they are workers. Those. the depth at which a deep metal detector easily finds a large object.


Surely many of you are fond of books and films about adventures. Take at least the famous Indiana Jones, whose name has become almost a household name. The romance of adventure, mystery, mysticism, treasures - all this has attracted, attracts and will almost certainly attract thousands of people at all times. But if in works of art the search for values ​​looks very exciting, then in reality it requires hard and painstaking work. A little lighten it up able modern technologies. And to be more precise - metal detectors, which will be discussed in this article.

First, let's figure out what kind of device it is. A metal detector is a device that allows you to detect metal in a neutral or weakly conductive environment. These environments may be different, but the models from our rating are used, as a rule, for searching in the soil. This, coupled with advances in electronics that made it possible to create a compact and lightweight device, made metal detectors popular among treasure hunters. Moreover, both among amateurs and among professionals.

And here it is worth understanding that a metal detector is a device for which design and beauty are not important. It is, first of all, a complex tool for a specific task, and therefore regular updates and improvements in technology are needed to better determine metals. Ideally, in order to choose a device specifically for your needs, you need to have a good understanding of such terms as “metal discriminator”, “pinpoint”, “detection depth” and many others. We will move on to the rating, where we will consider models divided into categories depending on the cost. It is much easier for beginners, and the functionality directly depends on the price of the device.

The best inexpensive metal detectors for beginners: budget up to 20,000 rubles.

The first category is addressed to the most inexperienced treasure hunters, for whom the chosen metal detector will be the first, and therefore it is very important to choose a model that will not empty your wallet - hence the conditional price limit of 20 thousand rubles. Of course, you can decide that it is much better to pay extra 10 thousand and get a device at a higher level, but such a decision is only partly reasonable. Firstly, it is far from a fact that treasure hunting will captivate you enough to spend large sums on it. Yes, if you have been out searching with your friends for more than a year, the answer is obvious, but in all other cases it is worth moderating your ardor. Secondly, more expensive models have more functionality that is very difficult for a beginner to master. Therefore, even a significant advantage on paper over a budget model can be absolutely useless in the hands of an inexperienced search engine. In general, if you know exactly what you need, scroll down to the next category. For beginners, we advise you to familiarize yourself with the rating of the best inexpensive metal detectors.

5 Minelab Go-Find 11

Light weight
Country: Australia
Average price: 7490 rubles.

Treasure seekers praise the inexpensive Minelab metal detector very much. With a detection frequency of 7.8 kHz and a 20 cm coil, it increases the accuracy of finding non-ferrous and ferrous metals. There is moisture protection, which allows you to continue searching for coins in water at a depth of up to 15 cm. Reviews often mention the light weight, only 1 kg, and the compactness of the device, which is ideal for long searches and hiking trips.

The metal detector is powered by four AA batteries. There is a sensitivity setting and two search modes. The first one searches for all metals, the second one ignores garbage. But in such a simple model, gradation does not guarantee a 100% result. However, Go-Find 11 can rightly be considered the best budget option for the first metal detector.

4 Deteknix Quest Q20

The best model for land and water
Country: USA (made in China)
Average price: 16900 rubles.
Rating (2019): 4.5

metal detectorfrom America conquered the Russian market with its low price and high search accuracy. Buyers often note in reviews that this state employee is not inferior to expensive and advertisedmetal detectors- finds metals at a depth of up to 80 cm. The round coil is waterproof, so it calmly searches for ferrous and non-ferrous metals in water up to 15 cm deep.

The power element is a crown. The frame is made of plastic and metal. It is adjustable in length from 114 to 135 cm and has a weight of 1.35 kg. There are three search modes: all metals, DISC, TONE. The first mode is for search absolutely any metals, including gold , the second - to ignore metal debris, the third - for a more efficient search for non-ferrous metals.

The best mid-range metal detectors: budget up to 30,000 rubles.

Metal detectors of this group can hardly be called devices for beginners. Yes, they are still not very difficult to master, but they already have a significantly expanded functionality, which, if not increasing the area and depth of detection, certainly makes metal recognition more convenient and accurate. According to the possibilities, the price, of course, also increases. It does not differ so much from devices in the budget segment, but it is already difficult to call it affordable.

In general, metal detectors of the middle price segment can be addressed to people who are serious about pursuing their hobby. For such users, searching for valuables is not yet work, but it is no longer just a pleasant pastime a couple of times a month. It is also worth noting that devices from this category can be safely purchased by people who, over time, are going to devote even more time and effort to searching, because the functionality is not very critically different from premium models, and therefore such metal detectors are purchased for many years. You can look at the best models in our rating.

The name of the metal detector is more than speaking: lat. Deus translates to "God". In this model, the manufacturer has collected the most advanced technologies at the moment. Moreover, these innovations are useful not only directly for searching for objects, but also add elementary convenience. What is worth the lack of wires. Yes, yes, the coil, the electronic unit and the headphones are connected here “by air”. Of course, such a solution also has an unpleasant side - the need for constant charging of all elements. But lightness (only 970 grams) and convenience more than pay for this small drawback. Of course, in addition to this, the device has other features.

Flaws:

  • Some users note uncomfortable headphones

Any search engine has ever thought about how to improve the search characteristics of their device. Usually you want to increase both the sensitivity and the depth of detection.

Target detection depth depends on many factors.

The first and most important of these is soil mineral composition . The higher the mineralization, that is, the more alkaline or salty the soil, the less the depth of detection. If your metal detector has a manual ground balance, great. Tune it properly and it will give you more depth.

Further, the depth depends on target dimensions . And if you can easily find a coin with a metal detector at a depth of 25-30 cm, then an ax, shield or bell with the same device can be found deeper, at a level of 1-2.5 m. Decide on the size of the targets you are going to look for, and before that, work in the local library (in the archive). If you are looking for coins, you are on the way to the places of former settlements, and if you are looking for artifacts, then to the places of epic battles.

affect depth and weather . It is well known that wet soil conducts the signal better and it is possible to detect deeper objects on it. Therefore, the search is good in the morning, during dew, or after rain. But when there is snow on the fields, it is better to postpone the search - the depth will be almost none due to the thickness of the snow cover.

An important influencing factor is user's ability to correctly configure your metal detector. So, for example, constantly using discrimination and not paying attention to the threshold tone settings, it is very easy to miss up to 20% of good finds.

Three technogenic factors - frequency, coil characteristics and software on the control box - complete the list. Briefly about them, then: for deep search, they choose low-frequency devices (from 3 to 8 kHz), a large coil diameter (preferably DD), and it’s also a good idea to purchase a high-quality metal detector from a reliable manufacturer (Minelab, XP, White "s) in order to guarantee decent, non-buggy software.

As a result, in order to increase the detection depth of your metal detector, we advise:

  • thoroughly study the capabilities and settings of the device;
  • buy a new coil;
  • go out to search for dew or after rain.

And, finally, you can choose
