Platinum, silver и gold have always been the goal of treasure hunters. It is important to choose the right auxiliary equipment. In this article we will consider what metal detectors are, the principle of operation and what they are. Let's compare models in different price categories with the necessary set of functions.
Metal detector: purpose and principle of work
Metal detector for gold - an instrument that indicates the location of metal with different compositions in the ground or water. The equipment records the reflected signal, similar to an echo sounder. Based on the return signal, it determines if there is a particular metal under the search detector.
You need a receiving and transmitting antenna to function properly. VLF and PI metal detectors have an aligned antenna called a coil or frame. In order to catch a signal, the coil has to be shifted.
RF metal detectors have two coils about half a meter apart. They do not require constant displacement when working. There is another type of hardware, pinpointers, which are called precision pointers. They are capable of catching interruptions and eddy current changes produced by a metal object.
Table: types of metal detectors, pros and cons
|- Finds objects of small size; - Discrimination allows you to exclude from the search objects with a certain conductivity.
|- limited depth of object detection. - The maximum detection depth is 60 cm.
|- There is discrimination in the size of objects; - Designed for great depth.
|- conductivity interference cannot be excluded
|- finds objects at depth; - is designed to search for large objects
Metal detectors for gold: types and specifics
Not all metal detectors are the same. To see the difference, you need to study the characteristics of the device. High frequencies, more than 14 kHz, are important for finding small objects.
All search equipment can be divided into universal or specialized. The first type is suitable for different metals, including precious stones. There is a wide range of options and it is possible to make custom settings.
Specialized equipment is designed to detect gold in conditions where it is difficult to do so. Such equipment can cost a lot of money, which means it is only used by professionals. An example of such equipment is considered to be an electrochemical detector demon-yu from ultramag.
The purpose of such equipment is to find precious metals on a fresh or salty beach. The metal detector must have protection from water, high indication of detachment from the ground. Such requirements are due to the high mineralization of the soil, making it difficult to find. Therefore, the device must distinguish between signals coming from ferrous metal and directly from precious metal.
Precious jewelry is often hidden in the depths down to the knee. For this purpose, the gold detector must have a waterproof coil, protected housing. So it is possible to search for precious metals at a depth of up to 3 meters. To hear the sound of the device, it is better to use special headphones.
Underwater metal detector is suitable for diving to a depth of more than 3 m. There is equipment whose task is to search for massive metal objects lying at great depths outside the water. They do not detect small objects like jewelry or nuggets.
Requirements for an effective metal detector to search for gold
When choosing a metal detector, the following indicators are important:
- the quality of target separation;
- the size of the found objects;
- soil tune-up.
Qualitative separation of goals and discrimination
A quality detector must be able to distinguish gold from the iron. Devices with vDI from 0 to 99 show vDI precious metal from 40-45, while scrap metal is no more than 30. A precious metal signal can be given by metal affected by severe corrosion.
It is the job of discrimination to filter out the interference. The more thin bars the scale contains, the less chance of getting a false signal.
The magnitude of the target of the distinction
The index depends on the frequency at which the search is performed. The higher the frequency, the smaller the wave, and therefore the smaller objects can be found. The minimum allowable frequency for gold seekers is considered to be 14 kHz.
The more the depth is allowed for the device, the better. In this way there is a better chance of finding deposits that lie at depths of more than half a meter.
Adjusting the ground balance
The index can be adjusted automatically or manually. It is better when there is a manual and automatic balance at the same time. It is less likely to catch false signals.
Pricing factors for metal detectors. Price range
Pricing takes factors into account:
- model is made to search for gold or such a function was obtained by the method increasing frequencies;
- marketing costs;
- how recognizable the manufacturer is;
- instrument configuration.
Metal detectors for searching gold differ depending on the following price categories:
- 7 - 15 thousand rubles. -technique is designed to search for common metal;
- 16 - 30 thousand rubles. - individual models are capable of finding nuggets;
- 31 - 60 thousand rubles. - models designed for silver, gold;
- More than 60 thousand rubles. - technique used by professionals.

Where better to start looking for gold
If gold-bearing places far away, there is no way to get there, you can try your luck in nature. People often go to parks, beaches, and often lose jewelry there as well. A gold prospector will be able to test his or her equipment and try out different settings and functions. But it is important to remember the legal side of the issue and responsibility.
It is better to study the law and the terrain before exploring, so you know what you can do and what is punishable.
Tips about finding gold from metal detectors professionals
- you can scout the areas where there used to be, for example, Krasnoyarsk or Chita;
- it is important to study information about the places where you plan to search for gold with a metal detector (pay attention to the places where there are minerals, granite, shale and gneiss);
- search for traces gold miningThese can be mine dumps, blocks of rock that have fallen on the tracks, mines, and sinkholes in the ground;
- search for gold in rivers need to be in the recesses, resembling a "pocket", Nugget may be deposited in large underwater stones and their cracks;
- You have to allot a few days for the research;
- It is best to search for the treasure with a partner for safety reasons;
- beginner searcherdolzhden pick up equipment for the area of research, choosesso-appropriate clothing, shoes, backpack, pickaxe, shovel, tray, etc. (You can take to use a second-hand metal detector. Do not buy the necessary equipment on aliexpress, it is better to visit specialized outlets);
- should learn how to wash sand correctly: the tray should not be overloaded; pour out the water carefully, without haste;
- Each area has to be worked on particularly carefully;
- When searching, it is important to consider the flooding of rivers, because often the gold is not only near the bed, but also outside of it;
- you need to use a professional metal detector for gold;
- Smooth, water-rocked pieces indicate a long stay in the water, which means that they were brought from distant territories. (Bullion rough form is worth looking for literally underfoot);
- It is best to begin studies after a flood;
- Not everyone manages to find the treasure at once, it is important to be persistent and go to your goal.
What the Law Says About Finding Gold with a Metal Detector
With their own hands treasure hunter can find not only wealth, but also problems with the law. Difficulties that hobbyists may encounter are outlined in Article 243 of the Criminal Code of the Russian Federation "search and (or) removal of archaeological objects from the location on the ground, in the ground or under water, carried out without permission (open sheet), causing damage or destruction of the cultural layer".
What to do with the found ancient gold
Legislation in Russia in terms of the activities of treasure hunters is quite confusing. On the one hand, everything that was found in the ground, on 50% belongs to the state and so does the finder. But if this thing is more than 100 years, the searcher has no right to it, because it is state property, and it should be returned to the owner.
Can I be fined for searching for precious metals with a metal detector in a public place?
There are no penalties for the fact that a person decided to walk in a public place with a metal detector. But for a violation of Art. 243 of the Criminal Code a fine of up to 500,000 rubles or withholding of wages for several years is possible. Punishment is also possible in the form of:
- correctional work for up to one year;
- imprisonment for up to two years.
Conducting excavations at architectural heritage sites with "like-minded people" will be punishable by imprisonment for up to 6 years.
