Which search magnet is better, single-sided or double-sided? Select a search magnet. Which search magnet to choose
Every day a popular hobby is gaining momentum - searching for antiquities using a metal detector. Beginners are afraid to invest normal money in purchasing quality equipment. But based on my experience, I would like to note that only by investing money in quality things you get the expected result. Today there will be no long and tedious stories about all the benefits of quality attributes. Now I want to talk about search magnets, because by investing in a good magnet, you get two necessary search tools at once: a device for detecting and quickly removing any metal debris and a device for lifting metal products from the bottom of reservoirs. And there are a lot of relics hidden in the water.
When purchasing a search magnet, you should first decide on its purpose. If you need it for searching on land or vertical searching at the bottom of a reservoir or exploring the bottom of old wells, then it would be the best solution to purchase a one-sided magnet, that is, with one magnetic surface. This magnet is cheaper. But if you decide to purchase a universal tool, then you should buy a double-sided magnet with a side eye bolt.
I will not list the obvious advantages of this product, but I will say that with the use of such a device, the number of finds increases significantly. This is primarily due to the fact that when moving horizontally along the bottom of the reservoir under study, the magnet goes to a certain depth into the mud with the lower surface, and with the upper surface it collects all metal objects from the clogged bottom. This is a very important factor, since a magnet can attract small metal particles from a distance of no more than 15 cm. So, it’s clear: it’s better to buy a double-sided neodymium magnet. If you are planning to approach the purchase seriously, I advise you to familiarize yourself with the assortment of search magnets in the Mir Magnitov store - the largest niche store in the Russian Federation.
Places to find relics
The best places with the largest number of valuable finds are old bridges and military crossings. Good results are obtained from studies of mill whirlpools and pre-revolutionary wells. Sometimes even studies of drains and garbage pits and station toilets yield impressive results! After all, search magnets even magnetize jewelry containing a ligature. And what has never happened before: some thief, escaping from law enforcement agencies on a train, jumped out at the station and got rid of direct evidence by throwing it into the toilet - no one will swim there and look for it.
How to use a search magnet correctly
When buying a magnet with a high attractive force, which is written on the magnet in numbers after the letter F (this is the tearing load in kilograms), you should not worry about the possibility of being left without a magnet if it sticks well to the smooth surface of thick metal. For these cases, there is an eye bolt, by screwing it into the body of the magnet you will gradually tear it away from the surface. If the load is very large, as a rule, such cases occur with units with a power of 400 kg or more, you can use a lever to turn the eye bolt.
Don’t worry if a car suddenly ends up at the bottom, because its body is made of thin metal, and the magnet won’t stick to it too much. But you should definitely choose a climbing cord with a three-fold safety margin in case of snags.
Investing in a search magnet is a promising business, since the rare earth metals that make up its composition are only growing in price every year.
A neodymium magnet demagnetizes very slowly. On average, about 1% per year, provided the integrity of the case. Monitor the condition of the magnet coating and under no circumstances heat it above 80 degrees.
It is very convenient to use instead of a pinpointer: the batteries do not run out, and there is no unnecessary noise. It is better to use it when searching with a metal detector, storing it in a fabric bag. With the help of a bag, it will not become clogged and will be less susceptible to mechanical damage.
Neodymium magnets are very fragile and when chipped or broken they lose a lot of power.
People using pacemakers should handle them very carefully.
A very useful thing in everyday life, since you can always very quickly find a small metal object and filter liquids from chips.
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.
People who are passionate about archeology and simple search enthusiasts may have a question: which search magnet to choose? To answer this question, you need to accurately define for yourself the tasks that you are going to solve with the help of a search magnet. The nature of the tasks will determine how much magnet power you need.
Selecting a search magnet.
If you do not set yourself any specific tasks, a one-sided magnet with a pull-off force of 300 – 600 kg will suit you (a spare one won’t hurt). If you clearly understand the range of tasks that you have to solve (the nature of the search, the weight and size of the searched objects) using a search magnet, you can more accurately determine its power. The weight that a magnet can hold is indicated in the name of the model: for example, in the F300 model, the number 300 indicates the force of separation of this magnet from a flat surface.
As an example, let's look at the situation with a well, let's say you dropped a bucket there - for this it is quite possible to use an F100 brand magnet. Another example, you need to get out of some hard-to-reach place a key or other small metal object that has fallen there, you can safely choose a search magnet of the F80 brand: this is a compact magnet with great adhesion force. To clear an area of small metal objects, it is better to choose a double-sided search magnet - it is more suitable for such tasks.
Which search magnet to choose
Search magnets with a pull-out force of up to 150 kg are mainly intended for field work. Their main function is to search and lift metal objects from the bottom of reservoirs. Powerful neodymium magnets are used: to detect and lift metal objects from the bottom of deep crevices, holes, reservoirs, craters. If you plan to carry out search operations in the conditions described above, you should choose search magnets with high adhesive force, for example, F400 and higher. As a rule, objects that have lain in water are covered with a layer of rust and dirt, and this significantly weakens the adhesion to the magnet. When choosing a search magnet, you need to take care of a large power reserve.
What to look for when choosing a search magnet.
When deciding which search magnet to choose, you should pay attention to the reliability of the fastening and the shape of the magnet. As a rule, a search magnet has a steel body and a neodymium magnet built into it. The gap between the housing and the magnet is filled with epoxy glue. A search magnet usually has a special eye bolt to which a cable or rope is attached. This design of the search magnet has a sufficient margin of safety. IN
We continue to disassemble the treasure hunter's equipment and today we will pay attention to such an interesting thing as a search magnet. What is this thing, how to use it, what can you find, show a video, how much it costs and which models are the “coolest” according to reviews from searchers - read in this article.
So, search magnets are designed to search for metal objects, most often with such a magnet they are searched in places that cannot be reached with a metal detector, for example, in wells, in water and other places where searching with a conventional metal detector is impossible for a number of reasons (it is dangerous to climb into an abandoned well or there is no metal detector - amphibians like, to search under water). Although I will immediately note that searching with a magnet is not a safe activity, just look at the first photo.
The search magnet is made of a special alloy of three elements - the main one is neodymium, also iron and boron. Most often, familiar searchers ask and want to buy neodymium search magnets. The magnet itself is hidden in a durable metal case (the case is galvanized so that it does not rust); for attaching a rope or halyard, there is a special bolt in the form of a ring at the top of the magnet or on the side (depending on the model). You attach a magnet to it and throw it into the water in the hope of finding something valuable. Just like in a fairy tale - and the grandfather threw a search magnet into the water and it caught a broken metal trough)) This is exactly how they work - they throw metal objects into the water and take out metal objects, which are then handed over to the ferrous metal or, if they are valuable, they are sold at a higher price as valuable items , having value. So if you are searching on a river or pond, it is better to take a magnet with a bolt fastening on the side, since you will be “dragging” the magnet along the bottom and it will go along the bottom with its entire surface. By the way, magnets can be single-sided or double-sided.
There are a lot of ways to use a search magnet; I have even heard of cases where metal modern money was taken out of fountains using such a search magnet. After all, a magnet is a magnet because it can only hook products made of metal or a metal alloy; to be precise, such alloys are called ferromagnetic. For example, modern metal 10-ruble coins are made of steel in a non-ferrous metal shell, they cling perfectly to a magnet and you can catch a lot of them if you sit in the right place)) If you want advice, go to the beach, take a search magnet in your hand and move over the sand - you attach so many modern little things that after a couple of trips you’ll pay for such a magnet and still have some left over for beer.
So people who buy magnets make money by finding ferrous metal and other metals that are magnetic.
Another way to use a search magnet is perfect for attic search lovers. If you’ve ever tried to look for coins in powder, you know that there’s so much metal there that you’re simply blown away by the squealing of the detector. Therefore, in order to at least slightly reduce the amount of left-handed metal in the powder and prepare the soil-powder for searching with a metal detector, first walk through the powder with a search magnet. Be sure that you attach so many rusty nails and other iron that searching later with a metal detector will become much easier. Here's tip number 2 for using a magnet.
This strategy is also applicable for loose soil; I already talked about sand when searching on the beach. But sand is not only on the beach, there are fields where you dug for coins and the soil there was sandy. So use a search magnet there too.
Types of search magnets
The most important characteristic of a search magnet is its carrying capacity. if you were interested in them, then you know that they come in sizes of 200, 300, 400 and more kilograms. This means that the magnetization force is such that you can lift through the air a weight equal to the carrying capacity of the magnet. However, you should not think that if you threw a magnet into the water and hooked a powerful piece of iron at 300 kg, you will not be able to lift it with a magnet at 300 kg for a number of reasons - the first is that lifting a weight through the air is one thing, and the second is that pull it along the surface, where friction is also involved. This time. Secondly, if the iron is rusty, then it magnetizes much worse than new one. So it’s even more difficult to pull out rusty iron, and if the magnet is also low-power, then it’s a pipe altogether.
Next, it’s worth saying a few words about safety precautions, because some treasure hunters are so preoccupied with their hobby that they completely stop thinking with their own heads. Well, you have to come up with this - put your fingers between the search magnet and the iron pipe. The pipe could be magnetized and hit with such force that your fingers break once or twice. Therefore, think with your head about what you are doing and do not put your fingers or other parts of your body (think about your future children)) between the surface of the magnet and the metal object.
Also, when you carry a search magnet, stay away from iron objects, and in particular your car. Otherwise, if you are magnetized to it with such force, you will twist your hand (if you are carrying it by the bolt and inserted your finger into the ring) and put a big dent on your favorite car.
Manufacturers also say that the magnet affects cell phones and other electronics, and the electronics affect them. So, away with cell phones when you are “fishing” with a magnet.
If you buy a high-quality search magnet with a reserve of power and carrying capacity, follow safety rules and “fish” in promising places, then searching with a magnet will be no less exciting than searching with a metal detector. It’s really interesting when you throw it in, you feel it “takes the bite” and you drag it away, not knowing what you got there. Adrenaline is also present))
Among the most popular, it is worth noting the F series models from the city of Kaluga.
Price for search magnets
F 120 - for 120 kilograms, costs approximately 1300 rubles. There are also models for 150, 200, 300, 400 and 600 kg. The price is roughly like this:
150 kg - 2000 rubles
200 kg - 2700 rub.
300 kg - 3500 rub.
400 kg - 4300 rub.
600 - 6400 rubles
As you can see, the more powerful the magnet, the higher its cost. Therefore, buy search magnets according to your ideas; if you decide to “catch” small things on the beach, then the cheapest one will do; if you are looking for treasure, then take it with a reserve of at least 400 kg. Good luck with your search, colleagues.
And finally, a video of how people “catch” rifles and other joys of war diggers with a magnet.)) Yes, they catch everything that is made of metal, starting from ordinary pieces of iron and ending with the echo of war - grenades, mines, cartridges. So be careful out there people and good luck. As fishermen say - no bite, no catch.
And here they coolly picked up an old iron)) And then a grenade nahh..))
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.
