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 32.00 kg, which translates into high effectiveness in water. For beginners, we recommend lighter single-sided models (F80-F200), for advanced users - heavier double-sided (Two-Side) ones.

Double-sided holders (Two-Side) have two active magnetic surfaces and two mounting holes. Side mounting is ideal for throwing from the shore, as the magnet drags flat along the bottom. Single-sided magnets are usually lighter and cheaper but less effective for long throws.

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.

Most of our starter kits are complete and ready to use. 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.

This force applies to perfect adherence with the entire surface to a smooth, clean steel plate with a min. thickness of 20mm. In a river, objects are often rusty, silted, or irregular in shape (e.g., pipes), which drastically reduces grip strength. A large power reserve is essential in real search conditions.

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.

In contrast to many market offers, Dhit does not cut corners on components, which translates into a better results during every trip to the water.

Most magnets on the market have thin casings that crack during the first hard impact against concrete or rocks.

Many sellers use a trick by promoting the pull force measured only on the top hook. Interestingly, in the entire internet, there are virtually no recordings demonstrating the actual strength of competitor products on the side hook.

{In contrast to anonymous sellers, Dhit provides full support and real service assistance, which gives peace of mind after the purchase. Instead of risking with random brands, it is better to choose the market leader that cares about the satisfaction of searcher.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Apart from their superior magnetism, neodymium magnets have these key benefits:

Their strength is durable, and after around ten years it drops only by ~1% (theoretically),
Magnets perfectly resist against demagnetization caused by foreign field sources,
In other words, due to the smooth surface of nickel, the element becomes visually attractive,
The surface of neodymium magnets generates a maximum magnetic field – this is a distinguishing feature,
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 accurate forming and optimizing to individual requirements,
Key role in advanced technology sectors – they find application in hard drives, electromotive mechanisms, diagnostic systems, also modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in small dimensions, which enables their usage in compact constructions

Cons

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in strength. Often, when the temperature exceeds 80°C, their power decreases (depending on the size, as well as shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can corrode. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
Due to limitations in producing threads and complex shapes in magnets, we recommend using casing - magnetic mount.
Health risk related to microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can complicate diagnosis medical when they are in the body.
Due to expensive raw materials, their price is higher than average,

Holding force characteristics

Maximum holding power of the magnet – what affects it?

Holding force of 32.00 kg is a measurement result executed under the following configuration:

with the application of a sheet made of low-carbon steel, guaranteeing maximum field concentration
possessing a massiveness of at least 10 mm to avoid saturation
with a surface free of scratches
with zero gap (without coatings)
for force acting at a right angle (in the magnet axis)
at temperature room level

Magnet lifting force in use – key factors

Real force is influenced by specific conditions, including (from priority):

Gap (between the magnet and the plate), as even a very small clearance (e.g. 0.5 mm) can cause a reduction in lifting capacity by up to 50% (this also applies to paint, corrosion or dirt).
Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The shear force of the magnet along the plate is usually several times lower (approx. 1/5 of the lifting capacity).
Metal thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Plate material – mild steel attracts best. Alloy steels lower magnetic properties and holding force.
Base smoothness – the smoother and more polished the plate, the larger the contact zone and higher the lifting capacity. Unevenness acts like micro-gaps.
Operating temperature – neodymium magnets have a sensitivity to temperature. At higher temperatures they lose power, and at low temperatures gain strength (up to a certain limit).

Holding force was measured 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. Moreover, even a small distance between the magnet’s surface and the plate reduces the lifting capacity.

Warnings

Medical implants

Patients with a ICD have to keep an safe separation from magnets. The magnetic field can stop the operation of the life-saving device.

Metal Allergy

Nickel alert: The Ni-Cu-Ni coating consists of nickel. If redness happens, immediately stop handling magnets and wear gloves.

Threat to navigation

GPS units and smartphones are highly sensitive to magnetism. Direct contact with a strong magnet can ruin the sensors in your phone.

Risk of cracking

Beware of splinters. Magnets can fracture upon uncontrolled impact, launching shards into the air. Eye protection is mandatory.

Immense force

Use magnets consciously. Their powerful strength can surprise even professionals. Plan your moves and respect their force.

Dust explosion hazard

Fire hazard: Neodymium dust is highly flammable. Do not process magnets in home conditions as this risks ignition.

Safe distance

Avoid bringing magnets close to a wallet, computer, or TV. The magnetic field can destroy these devices and erase data from cards.

Do not overheat magnets

Watch the temperature. Heating the magnet above 80 degrees Celsius will ruin its magnetic structure and pulling force.

Crushing risk

Large magnets can break fingers in a fraction of a second. Do not place your hand betwixt two strong magnets.

Choking Hazard

Strictly store magnets away from children. Choking hazard is significant, and the effects of magnets clamping inside the body are fatal.
