Search magnets today are gaining great popularity not only among novice treasure hunters, but also among professionals. Naturally, a magnet cannot replace a treasure hunter, but with its help you can also make many amazing finds.
If a treasure hunter is actively used on land, then search magnets in the vast majority of cases are used to search for archaeological valuables at the bottom of rivers, lakes, crossings, etc.
It is necessary to think in advance about what finds can be found in a particular location. Based on their weight, you should choose a search magnet. They start at 120 kg, but can also reach 600 kg.
At the same time, the weight of the search magnet is no more than 1.5 kg. These figures indicate how heavy a load a magnet can not only lift, but also hold for a long period of time.
- by lifting weight;
- by price;
- by the number of eye bolts, etc.
In particular, the eye bolt can be screwed not only into the plane of the magnet, but also into its end part. The cheapest search magnets are single-sided. They are less effective naturally.
Double-sided magnets are more expensive. All of them are available at affordable prices on the website ndfeb-magnit.ru.
Of course, the most affordable search magnets are Chinese. However, if we are talking about a truly effective search, then you can refuse them. Of course, search magnets can be used to clear the field of small metal objects on the surface.
This is done so as not to break out with a shovel at every signal from the metal detector. Chinese analogues are also quite suitable for these purposes. But if the work is to be done at great depths, where the find is definitely covered with a large layer of silt and rust, it is better to rely on high-quality magnets.
In particular, a Russian manufacturer, which has production facilities in Kaluga (RedMag), produces magnets for the space industry. There is no doubt about their quality.
Of course, they are much more expensive than their Chinese counterparts. But with the latter, you will be able to pass by a sensational find, when a domestic product will allow you not only to detect, but also to pull an object weighing up to 600 kg to the surface.

Each of us, when choosing a search magnet, asked the question: “Which search magnet is best suited to our needs?” Manufacturers of search magnets have provided us with a wide choice and now we ourselves need to decide which search magnet we should buy. First of all, you need to decide on the tasks and purposes of purchasing a magnet. It is one thing to buy a search magnet for household needs, or as a convenient tool for the garage, and quite another as a tool for searching and lifting heavy metal objects from rivers.
Let's start with the hardest one, but... Perhaps of all search magnets, this is the most highly specialized tool. It's all about its weight - 4300 grams. Such a magnet is difficult to throw far and pull out manually; such a magnet is difficult to hold in your hands when doing some work in the garage or at a construction site. But such a tool is perfect for loading and unloading steel sheets, barrels, channels, etc. If you find old rails and want to load them, this magnet will be a great helper for you.
However, you will also be great at lifting weights. This magnet is much more versatile. This is the most popular search engine tool for searching wells, reservoirs and swamps. Possessing enormous power and relatively low weight (2200 grams), a 2x400 kg search magnet can be thrown far, and very heavy objects can be pulled out. This magnet is ideal for those who purposefully hunt for ferrous metal. Working like a small trawl, due to its own weight, a search magnet of 2x400 kg is strongly pressed to the bottom and easily overcomes vegetation for days. In addition, such a magnet is much more convenient for use in a garage or on a construction site.
It can be described as a universal tool of wide application. This magnet is great for searching in rivers and ponds. The weight of the magnet is 1900 g, which allows you to throw such a magnet far. A lifting force of 50-57 kg is quite sufficient to pull a drowned boat motor, gun, knife, etc. out of the river. This magnet is also suitable for swamps and ponds with sediment. The weight of the magnet allows you to throw it for a long time without getting tired. This magnet will be a great addition for picking up tools in your car or garage. It can be used to fix small dents on the car body.
One of the most popular is a lightweight and affordable search magnet for universal use. It is easy to take with you (1000 grams of weight) even on a hike, and it is interesting to walk with it along the banks of rivers and lakes. The power of such a magnet allows you to lift about 35-45 kg of metal. Depending on the thickness of the metal, the strength of the magnet’s magnetization also depends - the thicker the metal, the stronger the magnet’s magnetization.
A small one is perfect as a fastener collector, for searching for lost things in the grass, dry leaves, etc. In everyday life, with such a magnet you can easily find a needle, or pick up a bucket that has fallen into a well.

Why do you need and how to choose a search magnet?
You've probably already noticed that a mysterious group of products has appeared in the assortment of stores for search engines. There are very few products in this group and they are all called Search Magnets. Let's figure out together why a search magnet is needed.
Why are search magnets needed?
First of all, a search magnet is designed to search places hidden from conventional search methods. For example, using a search magnet you can search the bottom of a well, pond or small river. It is enough to tie a strong rope or cable to a search magnet and lower it into the magnet at the bottom of a reservoir or well. If there are objects made of iron, nickel and other magnetic materials at the bottom, then the search magnet will be magnetized to them and they can be easily retrieved without plunging into the water. But what interesting things could be hidden in a village well or the bottom of a river in the area of the crossing? Very interesting household items, as well as things that they tried to hide more reliably, for example, weapons hidden by deserters, partisans and other individuals with a darker past.
One more area the use of search magnets - clearing the intended search site of iron debris. It is enough to drag a search magnet along the surface of the earth so that it collects from the surface all the nails, pieces of steel wire, steel plugs and other search debris that litter fields, abandoned houses and settlements.
A search magnet can also be used when searching with a metal detector. If the metal detector signal disappears after you have dug a small hole, then a search detector will help you quickly find iron “garbage” in the screening or in the hole. What should you know when choosing a search magnet? The most important characteristic of a search magnet is its magnetic strength. In order to make the value of the magnetic force more clear to the buyer, it is expressed in kilograms. Search magnets have a magnetic force of 60 to 600 kilograms. The most popular magnets among search enthusiasts are magnets for 200, 300 kilograms; they have a reasonable price and are easy to use. More powerful magnets of 500 kilograms or more are in less demand. It seems that you can get half a ton from the bottom of the river. But such powerful magnets are needed for more precise fixation to thin metal with curves or to small metal surfaces. For the accuracy of the description, it is worth adding that testing and determining the magnetic strength of the search magnet takes place on a clean milled steel sheet 8-10 mm thick. Therefore, a search magnet must be purchased with a reserve.
When choosing a search magnet you need to choose a magnet that has a device for removing the magnet from the piece of metal on which it is magnetized. Otherwise, removing the magnet from the metal will take much longer than the search itself. Most often, the device for removing a magnet from metal is an eye bolt. The eye bolt performs two roles at once - a convenient place for attaching a rope or cable and a simple device for removing a magnet from metal. It is enough to screw the eye bolt all the way into the body of the search magnet and it can be easily removed from the found metal.
Search magnets come in single- and double-sided types. Double-sided magnets are more convenient and more efficient, due to the fact that they can be magnetized to the “target” by two sides, rather than one.
Selecting accompanying equipment for working with a search magnet
If you are going to use a search magnet to search at the bottom of reservoirs or wells, as well as to lift finds to the surface, then you will have to additionally purchase a strong rope and a winch for the magnet! Yes, a winch! How are you going to get your magnet out of the bottom of the swamp if it gets caught on a sunken tank? Of course, none of the search magnets will pull out a tank; it’s like dragging a “hippopotamus out of a swamp.” But you also can’t leave the magnet at the bottom because the rope breaks. Therefore, if you purchased a 200 kilogram magnet, then it is advisable to use it with a 250-500 kilogram rope and a similar winch. And of course, don’t forget to take with you a key or a strong wrench for screwing in the eye bolt, otherwise you risk returning home with a magnetized anvil
There are two types of search magnets: double-sided and single-sided. They also differ in size for each type from F 120 – F 600*2. When a person first encounters such diversity, he involuntarily asks himself the question - which magnet to choose? Below we will try to figure this out.
All search magnets are marked F (strength) and a number indicating the adhesion force of this product. For example, F 400x2 - adhesive force of 400 kg, and the designation x2 means that the magnet is double-sided. It is worth remembering that this is a “relative” adhesive strength, in fact it may differ, everything will depend on the metal to which the magnet is attached. The adhesion force is calculated: when the magnet contacts its entire area with a thick (at least 1 cm) polished steel plate, it is torn off strictly perpendicular to the surface. Under ideal conditions, such a search magnet holds more than 500 kg. It is difficult to achieve such results in magnetic fishing. Most often, the metal in the water is uneven, rusty and dirty; the magnet clings to it only with one edge, and not with its entire surface. Therefore, the magnet breaks off when pulling out a small piece of iron weighing only 40-50 kg. This is where everything will depend on the size of the search magnet; the larger it is, the better it will stick to the iron. This applies to “catching” large metals. If you plan to search for coins, spinners, etc., then a small one like F 200 will do the job. If you are looking for scrap metal, then search magnets from F 300 to F600 are best suited for this. Which one should you choose? It all depends on your physical and financial capabilities. Everyone can throw an average search magnet F300, F 400, F 600, but F400x2 or F600x2 will be more difficult without good physical strength. preparation. Keep in mind that the price of a search magnet depends on its size; the more powerful the magnet, the larger it is in size, and the price will be higher. An expensive magnet will pay for itself in 3-4 “catch”, because with it you will catch much more scrap metal than with a small one. If you are going to look for metal in large quantities, then buy a large magnet; if it catches something, it will hold it tightly.
Double-sided or single-sided magnet?
We’ve figured out the strength of search magnets and their sizes, now let’s see how double-sided and single-sided magnets differ. From the name it is already clear that it has one working surface - two. Double-sided has two holes - central and side, for attaching an eye bolt. A single-sided search magnet is more suitable for searching from piers, bridges, boats, as well as for searching in wells. A more universal search magnet is double-sided. It can be cast from the shore (the eyebolt is screwed into the side hole), as well as from bridges and boats (the eyebolt is screwed into the central hole).
Search magnets have become a very popular topic today. This kind of “fishing” attracts not only boys and scrap metal seekers, but also quite respectable and wealthy people. Why is this happening? There is a boy in every man, but not everyone likes traditional fishing. It happens that the fish is “capricious”, the gear is chosen incorrectly, the place is chosen poorly, and besides, you need to look for worms and prepare bait. And the fish itself... After all, you can buy it in a store. But with a magnet things are completely different. Here your tackle is always the same, but what you can catch with it is unknown. It is this intrigue that attracts. What if, on the next cast, the magnet takes with it not a rusty nail, but a rare dagger, a metal box with old chervonets, or a pistol from the times of the Great Patriotic War? Agree, this really tickles your nerves.
Search magnets have become widely available and at reasonable prices relatively recently. Modern technologies have reduced the cost of their production process, therefore, today, in order to get a magnet, you do not need to disassemble the old hard drive, just go to a store or on the Internet.
How to choose a magnet
At the same time, a beginner may have a reasonable question: how to choose a suitable magnet? After all, they differ both in size and in the force of attraction and cost. In reality, choosing the right product is not that difficult.
To begin with, we note that there are two types of magnets - single-sided and double-sided. They are distinguished by the fact that the first has only one working side of the magnet, while the second has two, respectively. Single-sided magnets provide only uniform fastening - the so-called. The eye bolt is screwed only into the center of the plane opposite the working surface. It also happens that a bolt with a hook for attaching a rope is soldered to the body in which the magnet is located. In a double-sided magnet, the bolt can also be screwed into the side part - the “edge”.
Looking ahead, we note that a double-sided magnet has undeniable advantages, which is why it costs more. Due to the nature of the one-sided magnet, it can only be used by lowering it vertically downwards. That is, they can be used from a bridge or a boat (if you are searching in a river or lake). It is also suitable for exploring old wells.
However, if you look at search engine channels on Youtube, you will notice that they usually throw a magnet while standing on the shore. For these cases, a double-sided magnet is needed. The “puck” should fall with its working side to the bottom, after which the magnet is guided along the bottom using a cable. A one-sided magnet will be of little use with this fishing method.
What weight should I choose?
We have already said that magnets come in two types according to their design. But when choosing a search engine, you need to take into account other properties and features. You must clearly understand why you need a magnet and where you will work with it. It is believed that search magnets must have an attractive force of at least 100-200 kg. At first glance it may seem like a lot, but in reality it is not. For example, a magnet that states that the force of attraction corresponds to 100 kg will only be able to hold the specified weight under ideal conditions. He will be able to lift vertically upward a flat metal plate with a smooth and clean surface. But if you slightly change the angle of application of the force, the magnet begins to move off the surface. This means that it will be able to drag barely half of the specified mass along the bottom. Now imagine what happens at the bottom of the river! The metal located there becomes overgrown with silt, sinks into the sand, and gets tangled in algae. So it turns out that you can hardly take out a thing weighing 10 kg on a “hundredth”! Don't forget about the current. When lifted off the bottom, the object immediately begins to vibrate and break off if the current is strong enough. Therefore, to search for various “artifacts” we can recommend magnets in the range of 200-400 kg. They will not attract unnecessary pieces of hardware, but they will reliably magnetize interesting things.
Making money from scrap metal is a completely different story. There really is so much metal waste in our rivers and lakes that it is quite possible to earn our daily bread from it. In this case, the “search engines” should be more powerful – in the range of 600-800 kg. Such magnets themselves weigh more than a kilogram, but they can easily pull out entire mountains of metal. There are cases when such magnets had to be torn off using machines. But with their help you can catch not only bicycles, but even motorcycles and the remains of cars.
Choice of ammunition
If you decide to start searching, then in addition to the magnet you will definitely need to purchase the appropriate cable. Don't skimp. Magnets are not that expensive, but losing even an inexpensive magnet due to a broken rope is very annoying. Most often, search engines purchase special nylon cables used by climbers. They are protected from abrasion and have a particularly strong middle core, which ensures that the cable will not break at the most inopportune moment. Choose the length of the cable based on your needs. Usually the length of the rope does not exceed 20 meters. It is physically impossible for even a strong man to throw a half-kilogram blank further. Be sure to purchase quality gloves. Cables and finds are very easy to cut and rub your palms. It is also advisable to have a lost and found bag. Finds from the bottom are often corroded by rust, covered with algae and silt, which is why they have an unsightly appearance and emit an unpleasant odor. So it’s inconvenient to put them in a regular bag or backpack.
Pay attention to how the magnet is attached. Study the appropriate instructions on the Internet and select the appropriate unit.
Search Magnet Care
A high-quality magnet does not require special care. It is made of an alloy of neodymium, boron, iron and has a stainless steel coating. It is housed in a high-quality stainless steel case. Therefore, all caring for a magnet is wiping it with a dry cloth and cleaning it from small metal particles that stick to it and get clogged into the holes.
The neodymium magnet itself is reliable and durable. Over 10 years, on average, it loses no more than 1% of power. It cannot be hit and, most importantly, it cannot be exposed to high temperatures. If you heat it to 80 degrees, it will completely demagnetize and turn into a useless blank.
Many people like to film their searches. Do not forget that exposure to a magnet can be harmful to any electronics. Not only the camera, but also a mobile phone with a laptop can easily fail. So keep all your gadgets at a safe distance.
Let's face it, non-ferrous and precious metals are not magnetic! And these are the immutable laws of physics. You can't argue with them. Therefore, only iron and other alloys can be caught with a magnet. Usually search engines boast about the keys, locks, nails, coins and other small things they found. Sometimes you can get various antiques: horseshoes, forged items, various tools.
It is quite common to find weapons and ammunition. This is a legacy not only of the 40s, but also of the 90s. It is better to stay away from such finds and return them to the bottom without regret. After all, no one has repealed the article for illegal trafficking in weapons and ammunition. But it’s not worth taking risks, hoping that the expert will not recognize your find as a weapon.
