💡 Check why professionals choose Dhit over cheap substitutes

Instead of believing fairy tales on YouTube with tests on uncertified equipment, see what really determines your magnet's power:

  • 📏 Magnet thickness in the casing (min. 10mm) – This is what matters most! Thin magnets are weak. Thanks to the 1cm thickness of N52 neodymium, your magnet "sees" metal even through thick rust and mud.
  • 🛡️ Armored protection (Black Epoxy) – Forget about rust. This coating doesn't chip when hitting rocks and protects the magnet in water much better than regular nickel, which fails quickly.
  • 🧲 Eyelets that don't steal power – Made of special non-magnetic steel, so they don't stick to the magnet and don't block the force. Important: mount only one eyelet at a time! Using 3 at once is a mistake that weakens the magnet.
  • 🧶 Certified rope (min. 8mm) – You gain the certainty that your gear won't stay at the bottom. It's thick and comfortable, so it doesn't cut your fingers when pulling out heavy scrap metal.
  • 🚀 Our advantage: We are the only ones combining the strongest N52 neodymium (10mm thick) with non-magnetic eyelets. This is real power and durability you won't find anywhere else.

Invest in solid equipment and enjoy the results!

It is worth betting on proven F200, F300, or F550 models from our offer, which guarantee real power. Model UMP 75x25 [M10x3] GW F200 PLATINIUM Lina / N52 offers an optimal weight-to-pull force ratio, which is important for repeated throwing. The choice depends on whether you plan to throw from the shore (double-sided) or from a bridge (single-sided).
The 2xTwo-Side version is more versatile, allowing the eyelet to be mounted in two positions. Top mounting works well when fishing from a bridge, pier, or well (vertical technique). Single-sided magnets are usually lighter and cheaper but less effective for long throws.
Our holders have a thick steel housing covered with an anti-corrosion layer (chrome, nickel, zinc). Avoid throwing the magnet against bridge pillars or hard obstacles. After each fishing trip, we recommend rinsing the magnet with fresh water and drying it.
Check the product title and description to see if you are buying just the magnet or the XL set. We often add thread glue to secure the eyelet against unscrewing in water. Using thread glue is crucial to not lose the magnet in silt.
The capacity given in the name (e.g., 365.00 kg) is the maximum value measured in laboratory conditions. The magnet may slide on round elements (bicycle frame) due to the small contact area. A large power reserve is essential in real search conditions.
Possessing and using a neodymium magnet to clean the bottom is generally legal, provided you are not searching for artifacts protected by law. Magnet fishing is an eco-friendly hobby if you clean the river from trash and scrap.
In contrast to other brands, Dhit does not cut corners on components, which translates into a better results during treasure hunting.
Dhit GOLD mounts utilize a robust construction that acts as a real armor for the magnetic core.
Many sellers employ a tactic by advertising the power tested only on the top hook. The Dhit brand focuses on full transparency by providing the actual capabilities of the magnet, so you can be sure during treasure hunting.
{By choosing Dhit, you support Polish engineering that perfectly understands the specifics of our waters. Instead of risking with unknown goods, it is better to choose the market leader that ensures the satisfaction of searcher.

Advantages and disadvantages of Nd2Fe14B magnets.

Benefits

In addition to their long-term stability, neodymium magnets provide the following advantages:
  • They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (in laboratory conditions),
  • Magnets effectively protect themselves against loss of magnetization caused by ambient magnetic noise,
  • Thanks to the glossy finish, the plating of nickel, gold-plated, or silver-plated gives an clean appearance,
  • They feature high magnetic induction at the operating surface, which improves attraction properties,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Possibility of detailed modeling as well as adjusting to specific requirements,
  • Universal use in innovative solutions – they find application in mass storage devices, electric motors, advanced medical instruments, and complex engineering applications.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in tiny dimensions, which makes them useful in miniature devices

Disadvantages

Disadvantages of NdFeB magnets:
  • Brittleness is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
  • Neodymium magnets lose force when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop of power (a factor is the shape and dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
  • Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
  • Due to limitations in producing nuts and complicated shapes in magnets, we propose using cover - magnetic holder.
  • Potential hazard related to microscopic parts of magnets are risky, if swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small components of these products are able to disrupt the diagnostic process medical when they are in the body.
  • With mass production the cost of neodymium magnets can be a barrier,

Pull force analysis

Maximum lifting capacity of the magnet – what contributes to it?

The load parameter shown concerns the peak performance, recorded under laboratory conditions, specifically:
  • with the application of a sheet made of special test steel, ensuring full magnetic saturation
  • possessing a massiveness of min. 10 mm to ensure full flux closure
  • characterized by smoothness
  • without any clearance between the magnet and steel
  • under axial application of breakaway force (90-degree angle)
  • at conditions approx. 20°C

Magnet lifting force in use – key factors

Holding efficiency impacted by working environment parameters, mainly (from priority):
  • Distance (betwixt the magnet and the metal), because even a very small clearance (e.g. 0.5 mm) leads to a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
  • Direction of force – highest force is reached only during perpendicular pulling. The shear force of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – too thin steel does not close the flux, causing part of the flux to be wasted into the air.
  • Metal type – not every steel reacts the same. Alloy additives worsen the interaction with the magnet.
  • Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, reducing force.
  • Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they lose power, and in frost gain strength (up to a certain limit).

Holding force was tested on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 5 times. Additionally, even a small distance between the magnet’s surface and the plate lowers the load capacity.

Precautions when working with neodymium magnets
Threat to electronics

Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of at least 10 cm.

Respect the power

Before use, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

ICD Warning

Warning for patients: Powerful magnets affect electronics. Keep at least 30 cm distance or request help to work with the magnets.

Shattering risk

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. We recommend safety glasses.

Serious injuries

Large magnets can break fingers in a fraction of a second. Under no circumstances place your hand betwixt two attracting surfaces.

Nickel allergy

Medical facts indicate that the nickel plating (standard magnet coating) is a common allergen. For allergy sufferers, refrain from touching magnets with bare hands or opt for versions in plastic housing.

Demagnetization risk

Monitor thermal conditions. Exposing the magnet above 80 degrees Celsius will permanently weaken its magnetic structure and pulling force.

Combustion hazard

Fire hazard: Rare earth powder is highly flammable. Do not process magnets in home conditions as this risks ignition.

Threat to navigation

Navigation devices and mobile phones are highly susceptible to magnetic fields. Direct contact with a strong magnet can ruin the sensors in your phone.

Do not give to children

NdFeB magnets are not intended for children. Accidental ingestion of multiple magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
