💡 Check why professionals choose Dhit over cheap substitutes

Don't be fooled by amateur online tests – go for certified quality and specific parameters that guarantee success:

  • 📏 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 75x24 [M8+M10] GW F 200 kg offers an optimal weight-to-pull force ratio, which is important for repeated throwing. For beginners, we recommend lighter single-sided models (F80-F200), for advanced users - heavier double-sided (Two-Side) ones.
The double-sided model attracts from above and below, increasing the chance of hooking a find. Top mounting works well when fishing from a bridge, pier, or well (vertical technique). The double-sided version increases search efficiency by 100%.
The magnet is glued into a solid steel cup and sealed with epoxy resin, protecting it from water. The housing significantly increases lifespan but does not make the magnet completely indestructible. After each fishing trip, we recommend rinsing the magnet with fresh water and drying it.
We offer both standalone holders and ready-made gift sets (depending on the selected option in the store). We often add thread glue to secure the eyelet against unscrewing in water. We recommend always securing the thread with glue or tightening the eyelet firmly before first use.
This force applies to perfect adherence with the entire surface to a smooth, clean steel plate with a min. thickness of 20mm. Dirt, rust, paint, and algae create a distance that weakens the magnet by even 70-80%. Therefore, to pull objects weighing 10kg from the water, a magnet with a capacity of 200-300kg is often needed.
Searches are allowed as long as you do not interfere with archaeological sites or search for weapons. It is worth acting responsibly, cleaning up after yourself, and caring for the environment by removing fished-out scrap.
Unlike many market offers, Dhit uses the highest quality components, which translates into a clear advantage during treasure hunting.
The unique way of gluing and seating the magnet in the Dhit housing creates a solid structure that absorbs impacts while fishing on difficult, rocky bottoms.
You should know that the identical magnet pulled by the side hook often has as little as 40 kg of strength instead of the promised 200 kg. The Dhit brand focuses on full transparency by stating the actual capabilities of the gear, so you avoid disappointment during treasure hunting.
{Unlike anonymous sellers, Dhit provides expert advice and instant service assistance, which is crucial after the transaction. Every mount is checked before shipping, which guarantees that you receive equipment of the defect-free.

Advantages as well as disadvantages of Nd2Fe14B magnets.

Advantages

Besides their exceptional strength, neodymium magnets offer the following advantages:
  • Their magnetic field is durable, and after around ten years it decreases only by ~1% (according to research),
  • They maintain their magnetic properties even under external field action,
  • In other words, due to the shiny finish of nickel, the element gains visual value,
  • Magnets are characterized by maximum magnetic induction on the outer side,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
  • Thanks to flexibility in constructing and the ability to customize to specific needs,
  • Significant place in high-tech industry – they are commonly used in computer drives, motor assemblies, advanced medical instruments, and technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in tiny dimensions, which allows their use in compact constructions

Weaknesses

Disadvantages of neodymium magnets:
  • They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
  • Neodymium magnets decrease their power under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
  • They oxidize in a humid environment. For use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • We suggest cover - magnetic mechanism, due to difficulties in producing threads inside the magnet and complicated shapes.
  • Health risk resulting from small fragments of magnets are risky, if swallowed, which becomes key in the context of child safety. It is also worth noting that small elements of these devices are able to complicate diagnosis medical after entering the body.
  • Due to neodymium price, their price is higher than average,

Lifting parameters

Optimal lifting capacity of a neodymium magnet – what contributes to it?

Information about lifting capacity is the result of a measurement for optimal configuration, assuming:
  • on a block made of structural steel, effectively closing the magnetic field
  • whose transverse dimension reaches at least 10 mm
  • with a surface cleaned and smooth
  • without the slightest clearance between the magnet and steel
  • under axial force direction (90-degree angle)
  • at standard ambient temperature

Lifting capacity in real conditions – factors

Real force impacted by specific conditions, such as (from priority):
  • Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) diminishes the magnet efficiency, often by half at just 0.5 mm.
  • Loading method – declared lifting capacity refers to detachment vertically. When attempting to slide, the magnet exhibits much less (often approx. 20-30% of nominal force).
  • Element thickness – to utilize 100% power, the steel must be adequately massive. Thin sheet limits the attraction force (the magnet "punches through" it).
  • Metal type – different alloys reacts the same. Alloy additives worsen the attraction effect.
  • Surface condition – ground elements guarantee perfect abutment, which increases force. Rough surfaces reduce efficiency.
  • Temperature – temperature increase results in weakening of induction. It is worth remembering the maximum operating temperature for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when the force acted perpendicularly, whereas under attempts to slide the magnet the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet and the plate lowers the holding force.

Precautions when working with neodymium magnets
Maximum temperature

Avoid heat. NdFeB magnets are sensitive to temperature. If you require resistance above 80°C, look for special high-temperature series (H, SH, UH).

Shattering risk

Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Handling guide

Handle magnets consciously. Their immense force can surprise even professionals. Stay alert and do not underestimate their power.

Pinching danger

Protect your hands. Two powerful magnets will join instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Compass and GPS

A strong magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Maintain magnets close to a device to avoid breaking the sensors.

Safe distance

Intense magnetic fields can corrupt files on credit cards, hard drives, and storage devices. Stay away of at least 10 cm.

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness occurs, immediately stop handling magnets and wear gloves.

Product not for children

These products are not toys. Eating a few magnets may result in them attracting across intestines, which poses a direct threat to life and requires urgent medical intervention.

Dust is flammable

Combustion risk: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Health Danger

Life threat: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have medical devices.
