Metal discrimination

So, if you want to find objects made of iron or alloys containing a significant part of it, then it makes sense to choose a metal detector based on the detection depth, because Enabling the discrimination function directly affects this indicator, and not for the better.

If the purpose of the search is non-ferrous metals (copper, bronze, silver, gold) or products made from them, then the discrimination mode is your good assistant, since it will make it possible to configure the device to exclude iron-containing objects from the detection area. And this, in turn, will allow you not to dig dozens of extra holes, which will save energy, nerves and time on your next trip.

Metal discrimination

— exclusion from the search of targets that are undesirable for detection based on their electrical conductivity.

Depending on the level of professionalism of the metal detector, the options for setting up metal discrimination change. The closer the device is to the initial level, the more simplified this process is and, which is quite logical, the adjustment itself is less accurate.

If the metal detector is equipped with a display, then it must have a visual image of the discrimination scale, which usually displays an indication of the object from 0 to 99. What does this mean? The closer the indicator is to zero, the less electrical conductivity the detected object has.

If we consider the electrical conductivity of pure metals, then the discrimination scale of the metal detector should look like this:

iron / nickel / zinc / aluminum / gold / copper / silver

This gradation is observed almost everywhere, but with a caveat - as a rule, not only the names of metals but also products made from them are indicated on the scale. This approach is completely fair considering that in most cases, for the manufacture of a particular item, be it jewelry, coins or beer caps, not purified metal, but its alloy is used. And, depending on what metal was used as an alloy (additive), the electrical conductivity of the product itself changes.

For example, zinc, nickel, platinum, and copper are added to gold jewelry, depending on the production technology. The first three metals have electrical conductivity closer to iron, i.e. even less than that of aluminum, therefore, when gold jewelry is detected, the discrimination scale will display a value between aluminum and iron, and accordingly the sound signal of the metal detector will be low.

If during the manufacturing process more copper was used than other alloys, then the signal will be higher (provided there is polyphony) and the indicator will show the presence of metal in the segment from aluminum to copper.

Possibilities of discrimination

Typically, budget metal detectors do not have wide discrimination settings and are capable of discriminating only against non-ferrous and ferrous metals. More complex and expensive devices have the ability to cut off ferrous metal objects and small non-ferrous objects that are not the object of the search. In these devices, metal discrimination can be adjusted and additional selective settings can be set. It is possible to set a cut-off threshold for unwanted objects, taking into account the type of metal and their size. Cheaper metal detectors, instead of such regulators, use fixed operating modes for metal discrimination, for example “coin search”, “relic search”, “all metals”. Modern metal detectors are also equipped with a liquid crystal screen, which displays the characteristics of the object, for example, such as the approximate type of metal, depth, electrical conductivity and size. Using such a screen, you can visually determine the nature of your target and decide whether to excavate or not. Other, more complex metal detectors replace the LCD screen with tones. Metals with low conductivity will give low signals, metals with high conductivity will give high signals.

Object detection method

The most popular methods are those described below.:

1. VLF (very low frequency) – operating frequency up to 20 kHz. The receiving and transmitting coils are placed in one unit. Having received a signal, the device shows what kind of metal was detected or whether the item belongs to garbage.
2. VFLEX is an improved version of VLF , most often used by its creator, Minelab. Here, not an analog signal is processed, but a discrete one, which speeds up processing and makes it better, minimizing the number of errors.
3. PI – pulse induction . Only one coil is used as a receiver and transmitter; it is most often used in models for underwater search in salt water bodies.
4. FBS – full-band spectrum . Another product from Minelab. There are several frequency generators and they are used simultaneously, which allows you to obtain all the information about the found object.

Coil design

Two types of designs of this element are used:

• mono - two circles of winding, one of which is placed in the second;
• DD - two windings that are located next to each other.

Mono coils cope better with extraneous interference from unnecessary metals (discrimination). But if the search is carried out in soil with a large amount of minerals, then you should choose a metal detector with a DD coil.

In addition, other parameters cannot be ignored:

1. Number of manual settings . They help adjust the operation of the device to a specific area and the task at hand.
2. Tonality (number of levels). Indicates the proximity of the find.
3. Ability to map finds.
4. Connecting the metal detector to gadgets or a computer to exchange data and save search results.
5. Autonomy . Can I use rechargeable batteries? How long does the charge last?
6. Purpose . Do you need a device to search exclusively in the ground or are you planning to work in water?

These points also affect pricing, and if you manage to identify functions that are unnecessary for your purposes, you will be able to buy a device with the ideal balance of price and performance.

Talking metal detector + smart discrimination

What do you expect from a smart metal detector? The answer to the most important question of any digger of all times - To dig or not to dig? The accuracy of the answer is ensured by the discrimination function. Dozens of factors are involved. And there is no reason for a large manufacturer to delve into your problems with vodka caps and foil. Metal gives a positive response; if you don’t want to dig, then drown out the whole sector. Well, if you block the visibility of gold, you still won’t know about it, there are no finds. But there is still a difference between foil and gold. The only question is the method and accuracy of determination. The day the metal detector called you smart. Check out this masterpiece!

In fact, the key to the future of the medical industry is in the hands of simple diggers. Let's say a manufacturer has made a self-learning smart metal detector. Where will the data in the system come from? From real cops. And the more you confirm or refute the predictions of a smart metal detector, the smarter it will become. Moreover, the metal detector itself will adapt to your specifics, wiring speed, temperature, even fatigue and mood (this is not a joke). But most importantly, the metal detector learns from each hole based on your findings. And it will be a real big date.

Do you understand the idea? An American MD manufacturer cannot delve into problems on the other hemisphere, where vodka corks and tin cans spoil the mood of diggers. And if you make a smart metal detector, then only self-learning ones! And the diggers themselves will teach their baby.

Watch this video. A real peek into the future of all smart metal detectors. It's funny at the end of the video. All metal detectors should be able to pronounce this phrase!

The metal detector's name is Mole, and he speaks in a female voice. Inconsistency)) Zoology, boy, gentle female voice. Add a print from the anime, and the article is ready. Personally, I like the name of the device Emma, ​​or Greta. Is it okay?

Why do I think this video is cool? Remember the Air Metal Detectors metal detector? It would seem that the very trend (reel + smartphone), looks decent, is looking for something. But... I judge everything by the results. Firstly, what does this metal detector do that others can't? Secondly, this project participated in the CES exhibition at the beginning of 2018. There are agents walking around there, looking for somewhere to deposit money. Any project that has even an ounce of real technology or production potential is showered with money on the same day. And since the Americans didn’t give money to Air Metal Detectors... Well, you understand.

You can make at least 10 Equinoxes at a million frequencies. If the system is closed, implemented for everyone and for no one, it is a dead end. But in Krot Smart I see exactly what will definitely become the future of all smart metal detectors. The vector is right, there are results, that’s who the money should be given to. Do you agree?

Thanks de-si-gn for the news!

How does a professional metal detector differ from an amateur one?

Amateur metal detectors differ from their “experienced” counterparts in a narrow range of settings and simple equipment. This is done so that a beginner in search matters can grasp the very principle of working with such a device, without overpaying for functions that they will not use.

Amateur devices have a small frequency range, a low level of filtering of extraneous noise, and they are not designed to operate in extreme conditions.

For example, in heavy rain, at low or high air temperatures, at great depths in fresh and salt water. And amateur metal detectors are not designed to search for precious metals, but they are good at distinguishing antiques.

Homemade metal detectors

In this section of our site about homemade metal detectors , I will collect: the best metal detector circuits , their descriptions, programs and other data for making a metal detector with your own hands . There are no metal detector circuits from the USSR or circuits with two transistors here. Since such metal detectors are only suitable for visually demonstrating the principles of metal detection, but are not at all suitable for real use.

All metal detectors in this section will be quite technologically advanced. They will have good search characteristics. And a well-assembled homemade metal detector is not much inferior to its factory-made counterparts. Basically, various circuits of pulse metal detectors and circuits of metal detectors with metal discrimination .

But to make these metal detectors, you will need not only desire, but also certain skills and abilities. We tried to break down the diagrams of the given metal detectors by level of complexity.

In addition to the basic data required to assemble a metal detector, there will also be information about the required minimum level of knowledge and equipment for making a metal detector yourself.

To assemble a metal detector with your own hands, you will definitely need:

This list will contain the necessary tools, materials and equipment for self-assembly of all metal detectors without exception. For many schemes you will also need various additional equipment and materials, here are just the basics for all schemes.
