💡 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. This specific magnet ensures a laboratory lifting capacity of up to 230.00 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. Top mounting works well when fishing from a bridge, pier, or well (vertical technique). 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. Avoid throwing the magnet against bridge pillars or hard obstacles. 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.
It is a technical parameter defining perpendicular break force, not the weight of an object in water. 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.
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 smartest investment because for the same money, you buy a premium mount that will serve you for much longer than budget alternatives.
The GOLD series utilize a robust construction that acts as a real armor for the magnetic core.
It is worth remembering that the same magnet pulled by the side hook can actually show only 40 kg of power instead of the declared 200 kg. GOLD mounts guarantees honest data by providing the actual capabilities of the magnet, so you avoid disappointment during real field work.
{By choosing Dhit, you support a local market leader that knows the conditions of local rivers and lakes. Every product is individually inspected before delivery, which ensures that you receive equipment of the defect-free.

Advantages and disadvantages of neodymium magnets.

Strengths

In addition to their pulling strength, neodymium magnets provide the following advantages:
  • They retain magnetic properties for nearly 10 years – the loss is just ~1% (according to analyses),
  • Neodymium magnets are remarkably resistant to demagnetization caused by external magnetic fields,
  • A magnet with a metallic nickel surface has better aesthetics,
  • Magnets are characterized by impressive magnetic induction on the outer layer,
  • Neodymium magnets are characterized by very high magnetic induction on the magnet surface and can work (depending on the shape) even at a temperature of 230°C or more...
  • Possibility of precise forming as well as modifying to atypical needs,
  • Significant place in high-tech industry – they find application in computer drives, electromotive mechanisms, precision medical tools, also technologically advanced constructions.
  • Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which allows their use in small systems

Limitations

Problematic aspects of neodymium magnets: weaknesses and usage proposals
  • They are fragile upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also increases its resistance to damage
  • When exposed to high temperature, neodymium magnets suffer a drop in force. 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
  • Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
  • Limited ability of creating nuts in the magnet and complicated forms - preferred is casing - magnetic holder.
  • Health risk to health – tiny shards of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
  • With large orders the cost of neodymium magnets is a challenge,

Lifting parameters

Maximum magnetic pulling force – what affects it?

The force parameter is a result of laboratory testing executed under standard conditions:
  • with the contact of a sheet made of special test steel, ensuring maximum field concentration
  • possessing a thickness of at least 10 mm to ensure full flux closure
  • with a plane cleaned and smooth
  • with zero gap (without paint)
  • during detachment in a direction vertical to the mounting surface
  • in temp. approx. 20°C

Lifting capacity in practice – influencing factors

Please note that the magnet holding may be lower subject to elements below, in order of importance:
  • Clearance – existence of foreign body (paint, tape, air) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Angle of force application – maximum parameter is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times smaller (approx. 1/5 of the lifting capacity).
  • Base massiveness – insufficiently thick steel causes magnetic saturation, causing part of the flux to be wasted to the other side.
  • Steel grade – the best choice is pure iron steel. Hardened steels may attract less.
  • Surface finish – full contact is obtained only on smooth steel. Rough texture create air cushions, reducing force.
  • Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate reduces the load capacity.

Precautions when working with neodymium magnets
Dust is flammable

Mechanical processing of neodymium magnets poses a fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Power loss in heat

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

Electronic hazard

Data protection: Neodymium magnets can ruin data carriers and delicate electronics (pacemakers, hearing aids, timepieces).

Keep away from children

NdFeB magnets are not intended for children. Eating several magnets can lead to them attracting across intestines, which poses a severe health hazard and necessitates immediate surgery.

Pinching danger

Mind your fingers. Two powerful magnets will snap together instantly with a force of massive weight, destroying everything in their path. Exercise extreme caution!

Caution required

Before starting, check safety instructions. Uncontrolled attraction can destroy the magnet or injure your hand. Think ahead.

Keep away from electronics

Note: rare earth magnets produce a field that interferes with precision electronics. Maintain a safe distance from your phone, tablet, and GPS.

Material brittleness

Protect your eyes. Magnets can explode upon violent connection, launching shards into the air. Wear goggles.

Skin irritation risks

A percentage of the population experience a hypersensitivity to nickel, which is the common plating for NdFeB magnets. Prolonged contact may cause dermatitis. We suggest use protective gloves.

Life threat

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Do not approach if you have electronic implants.
