💡 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 94x28 [3xM10] GW F300 GOLD Lina / N38 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). The double-sided version increases search efficiency by 100%.
This construction protects the brittle neodymium from direct impact against stones and the bottom. The housing significantly increases lifespan but does not make the magnet completely indestructible. Maintenance (e.g., WD-40) prevents surface corrosion of the steel housing.
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. The magnet may slide on round elements (bicycle frame) due to the small contact area. Therefore, to pull objects weighing 10kg from the water, a magnet with a capacity of 200-300kg is often needed.
If you find a dangerous object (unexploded ordnance) or an antique, you have a legal obligation to report it to appropriate services (Police, conservator). We recommend familiarizing yourself with current local regulations and heritage protection laws.
It is the best value because for the same money, you buy professional-grade equipment that will serve you for much longer than budget alternatives.
The unique way of mounting the magnet in the protective cup builds a unified structure that absorbs impacts while fishing on difficult, rocky bottoms.
You should know that the same mount used by the side hook can actually show only a fraction of power instead of the declared 200 kg. GOLD mounts focuses on full transparency by providing the actual capabilities of the magnet, so you can be sure during real field work.
{By choosing Dhit, you support a local market leader that perfectly understands the specifics of our waters. Every product is checked before delivery, which guarantees that you receive equipment of the highest quality.

Pros as well as cons of neodymium magnets.

Strengths

Apart from their notable magnetism, neodymium magnets have these key benefits:
  • Their magnetic field remains stable, and after approximately ten years it decreases only by ~1% (theoretically),
  • They possess excellent resistance to magnetic field loss due to external fields,
  • By covering with a shiny layer of nickel, the element gains an professional look,
  • Magnetic induction on the working part of the magnet is exceptional,
  • Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
  • Possibility of exact creating and modifying to precise needs,
  • Key role in advanced technology sectors – they are used in mass storage devices, electric motors, advanced medical instruments, as well as modern systems.
  • Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Cons of neodymium magnets: tips and applications.
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
  • We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
  • When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which prevent oxidation and corrosion.
  • Due to limitations in realizing threads and complex shapes in magnets, we propose using a housing - magnetic holder.
  • Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to be problematic in diagnostics medical in case of swallowing.
  • High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Pull force analysis

Breakaway strength of the magnet in ideal conditions – what it depends on?

Magnet power was determined for ideal contact conditions, taking into account:
  • using a sheet made of high-permeability steel, acting as a ideal flux conductor
  • with a thickness minimum 10 mm
  • with an ideally smooth touching surface
  • under conditions of no distance (surface-to-surface)
  • for force applied at a right angle (pull-off, not shear)
  • at temperature room level

Key elements affecting lifting force

It is worth knowing that the application force may be lower depending on the following factors, in order of importance:
  • Distance – the presence of foreign body (rust, tape, gap) interrupts the magnetic circuit, which lowers power steeply (even by 50% at 0.5 mm).
  • Pull-off angle – remember that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops drastically, often to levels of 20-30% of the nominal value.
  • Element thickness – for full efficiency, the steel must be adequately massive. Paper-thin metal restricts the attraction force (the magnet "punches through" it).
  • Steel grade – the best choice is pure iron steel. Hardened steels may generate lower lifting capacity.
  • Base smoothness – the smoother and more polished the plate, the larger the contact zone and stronger the hold. Roughness creates an air distance.
  • Temperature influence – high temperature weakens pulling force. Too high temperature can permanently damage the magnet.

Lifting capacity was assessed using a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, whereas under shearing force the lifting capacity is smaller. Moreover, even a slight gap between the magnet’s surface and the plate decreases the holding force.

Precautions when working with NdFeB magnets
Nickel allergy

Allergy Notice: The Ni-Cu-Ni coating contains nickel. If an allergic reaction appears, cease handling magnets and wear gloves.

Fire risk

Mechanical processing of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is difficult to extinguish.

Hand protection

Watch your fingers. Two large magnets will join instantly with a force of several hundred kilograms, destroying everything in their path. Exercise extreme caution!

Product not for children

Product intended for adults. Tiny parts pose a choking risk, causing serious injuries. Keep away from kids and pets.

Electronic devices

Avoid bringing magnets near a purse, computer, or TV. The magnetic field can permanently damage these devices and erase data from cards.

Threat to navigation

Remember: neodymium magnets generate a field that interferes with precision electronics. Maintain a safe distance from your mobile, tablet, and navigation systems.

Conscious usage

Be careful. Rare earth magnets attract from a distance and connect with huge force, often quicker than you can move away.

Health Danger

For implant holders: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to work with the magnets.

Do not overheat magnets

Standard neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Fragile material

NdFeB magnets are sintered ceramics, meaning they are very brittle. Impact of two magnets leads to them cracking into small pieces.
