💡 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 280.00 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.
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%.
Our holders have a thick steel housing covered with an anti-corrosion layer (chrome, nickel, zinc). Despite solid construction, neodymium is a brittle material and can chip upon very strong impact (e.g., against concrete). 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). In the package, you will find everything needed: strong rope (e.g., 20m), gloves, and hardware. We recommend always securing the thread with glue or tightening the eyelet firmly before first use.
The capacity given in the name (e.g., 280.00 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.
Searches are allowed as long as you do not interfere with archaeological sites or search for weapons. We recommend familiarizing yourself with current local regulations and heritage protection laws.
It is the smartest investment because for the identical price, you buy professional-grade equipment that will last for much longer than generic imports.
Most magnets on the market have weak shells that deform during the any strong impact against underwater obstacles.
Many distributors use a trick by promoting the pull force measured exclusively on the top hook. Interestingly, in the entire internet, it is hard to find recordings testing the actual strength of other brands on the lateral attachment.
{By choosing Dhit, you bet on Polish engineering that perfectly understands the conditions of local rivers and lakes. Instead of risking with unknown goods, stick with proven gear that cares about the happiness of searcher.

Pros and cons of Nd2Fe14B magnets.

Pros

Apart from their superior magnetism, neodymium magnets have these key benefits:
  • They virtually do not lose strength, because even after 10 years the decline in efficiency is only ~1% (based on calculations),
  • Magnets perfectly protect themselves against loss of magnetization caused by foreign field sources,
  • A magnet with a smooth gold surface looks better,
  • The surface of neodymium magnets generates a concentrated magnetic field – this is a key feature,
  • Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
  • Considering the ability of free forming and adaptation to specialized needs, magnetic components can be manufactured in a wide range of forms and dimensions, which amplifies use scope,
  • Key role in innovative solutions – they are used in mass storage devices, brushless drives, medical equipment, and multitasking production systems.
  • Thanks to efficiency per cm³, small magnets offer high operating force, in miniature format,

Limitations

Disadvantages of neodymium magnets:
  • Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only protects them against impacts but also increases their durability
  • We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
  • They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
  • Limited possibility of creating nuts in the magnet and complicated forms - recommended is cover - mounting mechanism.
  • Possible danger related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that tiny parts of these products can complicate diagnosis medical when they are in the body.
  • Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Holding force characteristics

Best holding force of the magnet in ideal parameterswhat contributes to it?

The load parameter shown concerns the maximum value, obtained under ideal test conditions, specifically:
  • with the contact of a yoke made of special test steel, guaranteeing maximum field concentration
  • possessing a massiveness of at least 10 mm to ensure full flux closure
  • with an ideally smooth touching surface
  • without any insulating layer between the magnet and steel
  • under vertical force direction (90-degree angle)
  • in temp. approx. 20°C

Practical lifting capacity: influencing factors

Effective lifting capacity is influenced by specific conditions, such as (from most important):
  • Air gap (between the magnet and the plate), since even a tiny distance (e.g. 0.5 mm) leads to a drastic drop in lifting capacity by up to 50% (this also applies to paint, rust or dirt).
  • Direction of force – highest force is reached only during perpendicular pulling. The resistance to sliding of the magnet along the plate is standardly several times smaller (approx. 1/5 of the lifting capacity).
  • Plate thickness – insufficiently thick plate does not accept the full field, causing part of the power to be wasted into the air.
  • Material type – ideal substrate is high-permeability steel. Stainless steels may have worse magnetic properties.
  • Smoothness – ideal contact is possible only on smooth steel. Rough texture create air cushions, weakening the magnet.
  • Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was performed on a smooth plate of optimal thickness, under perpendicular forces, in contrast under parallel forces the lifting capacity is smaller. Moreover, even a small distance between the magnet’s surface and the plate lowers the lifting capacity.

H&S for magnets
Magnets are brittle

Watch out for shards. Magnets can explode upon uncontrolled impact, ejecting sharp fragments into the air. We recommend safety glasses.

Powerful field

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

Operating temperature

Regular neodymium magnets (N-type) undergo demagnetization when the temperature exceeds 80°C. This process is irreversible.

Skin irritation risks

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If redness appears, cease handling magnets and use protective gear.

Phone sensors

Navigation devices and mobile phones are extremely susceptible to magnetism. Close proximity with a strong magnet can decalibrate the sensors in your phone.

Fire risk

Mechanical processing of NdFeB material carries a risk of fire hazard. Neodymium dust oxidizes rapidly with oxygen and is hard to extinguish.

Crushing risk

Risk of injury: The attraction force is so immense that it can result in hematomas, crushing, and even bone fractures. Protective gloves are recommended.

Magnetic media

Powerful magnetic fields can corrupt files on credit cards, HDDs, and storage devices. Stay away of at least 10 cm.

Health Danger

Medical warning: Neodymium magnets can turn off pacemakers and defibrillators. Stay away if you have electronic implants.

Choking Hazard

Product intended for adults. Small elements can be swallowed, leading to intestinal necrosis. Keep away from children and animals.
