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. This specific magnet ensures a laboratory lifting capacity of up to 180.00 kg, which translates into high effectiveness in water. The choice depends on whether you plan to throw from the shore (double-sided) or from a bridge (single-sided).

The double-sided model attracts from above and below, increasing the chance of hooking a find. The side eyelet ensures the magnet doesn't stand sideways or "on edge" during pulling. 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. Despite solid construction, neodymium is a brittle material and can chip upon very strong impact (e.g., against concrete). 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. Using thread glue is crucial to not lose the magnet in silt.

It is a technical parameter defining perpendicular break force, not the weight of an object in water. 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. Magnet fishing is an eco-friendly hobby if you clean the river from trash and scrap.

It is the best value because for the same money, you obtain professional-grade equipment that will serve you for much longer than generic imports.

The GOLD series utilize heavy-duty, thick-walled steel that acts as a real armor for the brittle neodymium.

It is worth remembering that the identical mount pulled by the side hook often has only a fraction of strength instead of the declared 200 kg. The Dhit brand guarantees full transparency by providing the real parameters of the gear, so you can be sure during real field work.

{In contrast to competitors importing from China, Dhit provides expert advice and real warranty help, which gives peace of mind after the transaction. Every mount is checked before shipping, which ensures that you receive equipment of the highest quality.

Advantages as well as disadvantages of rare earth magnets.

Strengths

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 perfectly protect themselves against loss of magnetization caused by external fields,
In other words, due to the metallic layer of nickel, the element gains a professional look,
Magnets exhibit impressive magnetic induction on the working surface,
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 accurate creating and adjusting to specific conditions,
Universal use in future technologies – they are used in mass storage devices, drive modules, precision medical tools, also complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Cons

Cons of neodymium magnets: application proposals

To avoid cracks upon strong impacts, we recommend using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
Neodymium magnets lose their strength under the influence of heating. As soon as 80°C is exceeded, many of them start losing their power. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 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 secure oxidation as well as corrosion.
Limited possibility of producing nuts in the magnet and complicated shapes - recommended is casing - mounting mechanism.
Health risk to health – tiny shards of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to disrupt the diagnostic process medical when they are in the body.
With large orders the cost of neodymium magnets is economically unviable,

Pull force analysis

Maximum holding power of the magnet – what it depends on?

The load parameter shown concerns the peak performance, obtained under laboratory conditions, meaning:

on a base made of structural steel, effectively closing the magnetic field
with a thickness minimum 10 mm
with an polished touching surface
under conditions of ideal adhesion (metal-to-metal)
during pulling in a direction vertical to the mounting surface
at standard ambient temperature

Lifting capacity in real conditions – factors

It is worth knowing that the working load will differ depending on elements below, starting with the most relevant:

Air gap (betwixt the magnet and the plate), as even a microscopic distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, corrosion or dirt).
Direction of force – maximum parameter is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the surface is typically several times smaller (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux penetrates through instead of converting into lifting capacity.
Material type – ideal substrate is pure iron steel. Hardened steels may attract less.
Surface condition – smooth surfaces ensure maximum contact, which improves field saturation. Rough surfaces weaken the grip.
Temperature – heating the magnet causes a temporary drop of induction. It is worth remembering the maximum operating temperature for a given model.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under a perpendicular pulling force, in contrast under attempts to slide the magnet the lifting capacity is smaller. In addition, even a small distance between the magnet’s surface and the plate lowers the holding force.

Warnings

GPS and phone interference

A powerful magnetic field negatively affects the functioning of compasses in phones and navigation systems. Maintain magnets near a device to avoid breaking the sensors.

Electronic devices

Data protection: Strong magnets can damage payment cards and sensitive devices (pacemakers, medical aids, timepieces).

Flammability

Powder generated during machining of magnets is combustible. Avoid drilling into magnets unless you are an expert.

Handling guide

Handle with care. Rare earth magnets attract from a long distance and snap with huge force, often faster than you can move away.

Health Danger

Warning for patients: Powerful magnets affect medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Product not for children

These products are not toys. Eating several magnets can lead to them pinching intestinal walls, which poses a severe health hazard and necessitates immediate surgery.

Allergy Warning

Studies show that the nickel plating (the usual finish) is a strong allergen. If you have an allergy, refrain from direct skin contact or select encased magnets.

Magnets are brittle

Neodymium magnets are sintered ceramics, meaning they are prone to chipping. Clashing of two magnets leads to them cracking into small pieces.

Permanent damage

Control the heat. Heating the magnet to high heat will ruin its magnetic structure and pulling force.

Crushing risk

Pinching hazard: The pulling power is so immense that it can cause blood blisters, crushing, and even bone fractures. Protective gloves are recommended.
