Hunting for artifacts: choose a metal detector

Охота за артефактами: выбираем металлодетектор

Well, dear reader, you were inspired by all the read materials and seriously decided to purchase a metal detector (hereinafter - MD) Or, as it is called in the Copar environment, a “device”. Just a device. The very thing with which we will look for various artifacts. We do not write “search for treasures,” since this is still not the most frequent find.

The most frequent find, the most desired find, under which the vast majority of metal detectors are “sharpened” - this is, after all, a coin. That is, it is a flat rounder made of non-ferrous metal, most often copper or an alloy based on it - bronze or brass. Less often silver, sometimes aluminum, sometimes low-grade silver - bilon, very rarely of gold. It happens that it is completely made of iron.

Some general information

Therefore, any metal detector designed to search for historical artifacts reacts most cheerfully and pertly to a circle made of non-ferrous metal.

For example, the aluminum cork, which in our fields is lying in dozens, and sometimes hundreds of times more than coins. This is the so-called “Alco-thaler,” as the copari jokes. Our people, alas, for the most part do not hold sober views on life.

Traffic jams from drunk "Charlie" often end up in compost heaps, along with the rest of the garbage, which then falls out onto the fields.

The signal from the aluminum cork is practically indistinguishable from the coin signal; none, not even the most advanced metal detector, discriminate it (distinguish it from the other “flower” and ignore). Therefore, here is the first knowledge about the object - if you are pushed into the device and at the same time claim that it discriminates aluminum and distinguishes aluminum plugs from coins, do not believe. Absolutely breach, such devices so far (as of November 2014) does not exist.


What does a newbie usually pay when buying a device? Of course, to the depth of the search! “He takes the lope?”, Is the first question asked by the “treasure hunter”. The second question: “Is it worth it?”.

The depth of detection is always spelled out in the accompanying documents. Moreover, they write, as a rule, the depth of detection of the coin. But it should be remembered that coins are different - there is a 30-gram thaler, with a huge shielding surface, and sometimes a weightless miniature boratin or even a full-sized flake on the little finger.

Therefore, let us together with you declare a “middle” coin to the Soviet penny, and from it we will dance.

Devices are different. The most unpretentious will find in a damp soil a flat penny lying at a depth of 25 cm, well, those devices that are more serious will notice (unreliably, but they will notice) coins at a depth of 60 cm. But the greater the depth, the less accurate is the discrimination of the device. That is, what lies there, deep under the ground - a gold coin or a rusty nail MD will not tell you.

The search conditions are very different and the conductivity of the soil is a very variable value, and the same coin can lie flat or on the edge. She can lie alone, and can be among the iron garbage.

Potential copier should be warned that the majority of coins and other finds lie at a depth of a spade bayonet. A device that takes much deeper is simply not needed.

And let's imagine that you and I have a device with a super-maximum search depth and, as a result, rotten discrimination? And if he will periodically give you some kind of "rotten" signal at a 60-centimeter depth, think for how many holes do your physical forces hold and how many nails, bolts or pieces of aluminum wire will your emotional forces suffice? Believe me, not much.

Let's estimate. With an average number of finds in the place of average “badness” we will find approximately 3 coins per hour. Each coin will have about a dozen “left” finds - traffic jams, sleeves, shrapnel, wire. It already turns 30 per hour. Although what is there “30 per hour” ... More, much more! If we consider that the shortest search day barely fits into 3 hours, then it is easy to calculate how many holes you have to dig and how many times to bend down and sit down. This is me to the fact that the beginner does not need to chase the extreme depths. The bayonet of your shovel is the maximum depth of the search and that’s enough for now.

Although there are devices that are specifically designed to search for large metal objects at extreme depths - the so-called “depths”. But this is a completely different, separate story.

A little more about discrimination

Another important criterion that should be paid attention to when choosing an MD is the discrimination already mentioned above. That is, the ability of the device to distinguish ferrous metal from color. Discrimination can be, depending on the selected search mode, that the device simply ignores “ink” and “hawkes” exclusively “flowers”, or that it signals the discovery of different metal from a different sound or a different tone of sound. signal.

But here is not so simple. As mentioned above, the device is sharpened on a coin, so for large pieces of ink, for example, if you have a plowshare under the coil, it happily “screams” with a clear color signal.

Also “flowers” ​​ring and heavily rusted iron items. However, information about the discovery can be obtained not only by means of a sound signal, but also by visual means - on the display, if it is provided for in your device.

As for my personal preferences, I’m closer to finding one ears with a multi-tone instrument. Multi-tonality is when every metal object in the search zone has its own special “voice” and cacophony in headphones, a person who has learned to understand his device very clearly imagines the whole picture of what is underground right in front of him. I can hear the wire, the sleeve, the shrapnel very clearly, but, alas, I don’t distinguish the cork from the coin, so you have to dig any color signal.


Another important criterion - the tightness of the device. And pay attention, if we are talking about tightness, then you should always find out what tightness is meant - the brain, the coil, or both.

The search is not always under the sun on a dry field.

Personally, I have decided the question of the integrity of the brain (no need to laugh, get used to slang) with a plastic bag, which I put on them with the first drops of rain. The package is then fastened with electrical tape.

Price and manufacturer

The following criteria for choosing a device are price and manufacturer.

I have seen how Chinese-made devices work, whose names differ only by a couple of letters from the best examples of the American and French electronics industries.

They work, as a rule, not bad and not for long. Before my eyes at such a device, the katuha first exfoliated. The owner dried it, filled it with silicone and glued it with epoxy.

Then, about a week later, the brains fell off the bar, they had to be repaired in the field with the help of available tools. Well, then, after a couple of field trips, the bar itself broke exactly in the middle. Part of it was later replaced by a knee telescopic rods. However, the device is still working, so I am looking forward to seeing new Hochmas from it.


The most important selection criterion is ergonomics. If the length of the bar is simply adjusted to your height, then, alas, you cannot do anything with the weight of the device. Weight is different and even 100 grams play a big role.

Choose also the most convenient for you grip, there are only two.

The first conditionally we will call the “writing boy” the second - the same as we keep the hacksaw when sawing. Do you understand the images? If not, look at the photo.

And at the end of my story I want to warn you that in all post-Soviet countries there have appeared dishonest comrades who unsuccessfully try to “push” newcomers to the army mine detectors IMP-1 and IMP-2. In the Copar environment, they are called “clubs” for their similarity in shape. They are absolutely not suitable for our occupation. Moreover, it is said about them that with their help you can only find a cover from the sewer and if you know exactly where it lies. Exaggerate, I think, but this device is designed to search for mines - heavy metal objects.

That's all about the devices, in short. You need to choose the device that you like. But do not rush to draw conclusions about the potential of his new friend immediately after the first exit in the field. Learn a little mutual understanding.

Personally, after I first came out to the field with the device, which I have not parted for the third year, I was very disappointed in him and even had a desire to shake him about a tree trunk so that he would not suffer and did not torture me. Full understanding came about after the tenth exit. Now we do not spill water with him. What and you want.
