💡 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. This specific magnet ensures a laboratory lifting capacity of up to 32.00 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 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%.
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. We recommend always securing the thread with glue or tightening the eyelet firmly before first use.
The capacity given in the name (e.g., 32.00 kg) is the maximum value measured in laboratory conditions. The magnet may slide on round elements (bicycle frame) due to the small contact area. 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). It is worth acting responsibly, cleaning up after yourself, and caring for the environment by removing fished-out scrap.
It is the best value because for the identical price, you obtain a premium mount that will last for many seasons than budget alternatives.
A special technology of gluing and seating the magnet in the Dhit housing builds a unified structure that absorbs impacts while fishing on difficult, rocky bottoms.
You should know that the identical magnet pulled by the side hook can actually show as little as a fraction of strength instead of the promised 200 kg. Interestingly, in the web, there are virtually no videos testing the real side-pull force of other brands on the side hook.
{Unlike competitors importing from China, Dhit provides full support and instant warranty help, which gives peace of mind after the purchase. Instead of risking with random brands, it is better to choose proven gear that ensures the satisfaction of searcher.

Pros and cons of Nd2Fe14B magnets.

Strengths

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:
  • Their strength is durable, and after approximately ten years it drops only by ~1% (theoretically),
  • They have excellent resistance to magnetism drop when exposed to external fields,
  • Thanks to the reflective finish, the surface of Ni-Cu-Ni, gold-plated, or silver gives an modern appearance,
  • Magnets are characterized by excellent magnetic induction on the working surface,
  • Through (adequate) combination of ingredients, they can achieve high thermal resistance, allowing for action at temperatures approaching 230°C and above...
  • Considering the potential of accurate forming and adaptation to specialized requirements, NdFeB magnets can be modeled in a wide range of shapes and sizes, which amplifies use scope,
  • Significant place in high-tech industry – they find application in hard drives, electric drive systems, precision medical tools, as well as other advanced devices.
  • Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in small dimensions, which allows their use in compact constructions

Cons

Disadvantages of NdFeB magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can fracture. We advise 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 weakening 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 extremely resistant to heat
  • Magnets exposed to a humid environment can rust. Therefore while using outdoors, we recommend using waterproof magnets made of rubber, plastic or other material protecting against moisture
  • Limited ability of creating threads in the magnet and complex forms - recommended is casing - mounting mechanism.
  • Possible danger to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the context of child health protection. Furthermore, tiny parts of these products are able to complicate diagnosis medical when they are in the body.
  • Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

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

The declared magnet strength refers to the peak performance, recorded under laboratory conditions, namely:
  • using a sheet made of mild steel, acting as a circuit closing element
  • whose thickness reaches at least 10 mm
  • characterized by lack of roughness
  • without the slightest clearance between the magnet and steel
  • under vertical force vector (90-degree angle)
  • in neutral thermal conditions

Key elements affecting lifting force

It is worth knowing that the application force will differ depending on the following factors, in order of importance:
  • Gap between surfaces – every millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the pulling force, often by half at just 0.5 mm.
  • Load vector – highest force is obtained only during pulling at a 90° angle. The resistance to sliding of the magnet along the plate is typically many times lower (approx. 1/5 of the lifting capacity).
  • Base massiveness – insufficiently thick sheet does not close the flux, causing part of the power to be lost into the air.
  • Metal type – different alloys reacts the same. Alloy additives weaken the interaction with the magnet.
  • Surface condition – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces reduce efficiency.
  • Operating temperature – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Holding force was tested on the plate surface of 20 mm thickness, when a perpendicular force was applied, in contrast under shearing force the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Warnings
Medical implants

Individuals with a ICD have to keep an absolute distance from magnets. The magnetism can stop the functioning of the implant.

Fire risk

Combustion risk: Neodymium dust is explosive. Do not process magnets in home conditions as this risks ignition.

Pinching danger

Mind your fingers. Two large magnets will snap together instantly with a force of massive weight, crushing everything in their path. Be careful!

Do not give to children

Only for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store away from children and animals.

Safe operation

Handle magnets consciously. Their powerful strength can shock even experienced users. Be vigilant and respect their force.

Protect data

Intense magnetic fields can erase data on credit cards, HDDs, and storage devices. Keep a distance of min. 10 cm.

Heat warning

Monitor thermal conditions. Exposing the magnet to high heat will ruin its properties and strength.

Eye protection

Neodymium magnets are ceramic materials, which means they are prone to chipping. Clashing of two magnets leads to them cracking into shards.

Nickel allergy

Warning for allergy sufferers: The nickel-copper-nickel coating consists of nickel. If an allergic reaction occurs, immediately stop working with magnets and use protective gear.

Magnetic interference

Remember: neodymium magnets produce a field that disrupts sensitive sensors. Keep a separation from your mobile, tablet, and navigation systems.
