Treasure hunting is becoming more and more popular, which is why many people choose it as a hobby. But, unfortunately, the earth is yielding fewer and fewer good finds because many people have gone searching underwater, since the depths of our rivers, lakes, seas and oceans have not yet been explored enough. But, unfortunately, equipment for underwater searches is quite expensive, and not everyone can go underwater search, so many people choose searches with a neodymium search magnet as their first experience. Let's figure out what kind of device a neodymium search magnet is, and how is it useful for search engines?
A neodymium search magnet is a composite product made of a steel cup, an eye bolt, and a powerful neodymium magnet; as a rule, this structure is coated with a layer of zinc to prevent the rapid development of corrosion when used in water. As a rule, the choice of search magnets is quite small, but there are also enough manufacturers here, for example Nepra, Redmag, Triton, etc. Search magnets also differ in the method of fastening (one-sided, double-sided), as well as their tensile strength, which is measured in kilograms; naturally, the greater this ability, the greater the weight of the search magnet itself. For beginners, the advice is to start with a magnet of an average of 250 kg with a magnetic breaking force, this is quite enough, with a high breaking force of 400-800 kg, magnets are suitable for professionals in their field, since they are quite heavy for throwing into the water, and It will be difficult to unhook such a magnet from massive metal structures. I think one of the significant disadvantages of search magnets is the lack of the ability to magnetize to non-ferrous metals, only to ferrous types of metals. But even more so, the range of its use under water is quite large, for example, by seekers of military artifacts, scrap metal seekers, even they catch coins that contain ferrous metal.
But what about its use on sushi, is it possible or not? Here, unfortunately, the search magnet is not so in demand, but experienced treasure hunters use it as an element for clearing a small search site, first passing with a magnet and collecting all the small pieces of ferrous metal from the surface, and then walking around with a metal detector, thereby clearing the place of debris and increasing your chances of finding a small useful target made of non-ferrous metal, for example, scales, a small cross on the body, a tip… This tactic of using a magnet has also caught on with those who like to dig, which greatly simplifies the digging with a metal detector in heavily littered places, by removing a layer of earth they pass there with a powerful search magnet, and then with the device.
Regarding the rules of operation, the search magnet is quite simple, here you need to be careful and not stick your fingers between the surface of the magnet and the metal surface, as this can lead to injury; you should not throw it near large structures made of iron, concrete or metal, as it will be removed from It won’t be very easy to get there; it may end up with the magnet remaining there. As for storage, everything is quite simple here, just wipe it well with a cloth to remove water and silt and put it in a dry place away from metal, it is not advisable to store the magnet next to it or, especially, hanging it on a metal surface, since then it can Magnets lose their power over time.
So, fellow searchers, we can conclude that a search magnet is a useful thing that every connoisseur of the search business should have.
