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!

For underwater searches, we recommend specialized holders from the GOLD series, designed for working in difficult conditions. Model UMP 75x24 [M8+M10] GW F 200 kg offers an optimal weight-to-pull force ratio, which is important for repeated throwing. For beginners, we recommend lighter single-sided models (F80-F200), for advanced users - heavier double-sided (Two-Side) ones.
The 2xTwo-Side version is more versatile, allowing the eyelet to be mounted in two positions. 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. The housing significantly increases lifespan but does not make the magnet completely indestructible. 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). A full set usually contains: magnet, polypropylene rope with appropriate strength, protective gloves, hook, and carabiner. We recommend always securing the thread with glue or tightening the eyelet firmly before first use.
This force applies to perfect adherence with the entire surface to a smooth, clean steel plate with a min. thickness of 20mm. Dirt, rust, paint, and algae create a distance that weakens the magnet by even 70-80%. A large power reserve is essential in real search conditions.
Possessing and using a neodymium magnet to clean the bottom is generally legal, provided you are not searching for artifacts protected by law. Magnet fishing is an eco-friendly hobby if you clean the river from trash and scrap.
By selecting the Dhit brand, you get a product of a significantly higher standard and real N52 grade for the average cost.
The unique way of gluing and seating the magnet in the protective cup creates a solid structure that dampens shocks while fishing on difficult, rocky bottoms.
Many distributors employ a tactic by advertising the power tested only on the vertical mount. GOLD mounts focuses on honest data by providing the real parameters of the magnet, so you avoid disappointment during treasure hunting.
{Unlike anonymous sellers, Dhit provides full support and instant warranty help, which is crucial after the transaction. Don't risk it with unknown goods, stick with proven gear that cares about the happiness of searcher.

Advantages and disadvantages of neodymium magnets.

Advantages

Besides their magnetic performance, neodymium magnets are valued for these benefits:
  • They retain full power for around ten years – the loss is just ~1% (based on simulations),
  • They are extremely resistant to demagnetization induced by presence of other magnetic fields,
  • Thanks to the shiny finish, the surface of Ni-Cu-Ni, gold, or silver-plated gives an modern appearance,
  • Magnets are distinguished by maximum magnetic induction on the active area,
  • 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 modeling and optimizing to individual requirements,
  • Huge importance in innovative solutions – they find application in magnetic memories, electromotive mechanisms, advanced medical instruments, also industrial machines.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in miniature devices

Limitations

Disadvantages of NdFeB magnets:
  • At very strong impacts they can break, therefore we recommend placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
  • Neodymium magnets decrease their power 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
  • They rust in a humid environment - during use outdoors we advise using waterproof magnets e.g. in rubber, plastic
  • Due to limitations in creating threads and complex forms in magnets, we recommend using a housing - magnetic mechanism.
  • Health risk resulting from small fragments of magnets are risky, when accidentally swallowed, which becomes key in the context of child health protection. Furthermore, small elements of these products are able to disrupt the diagnostic process medical after entering the body.
  • Due to expensive raw materials, their price exceeds standard values,

Pull force analysis

Best holding force of the magnet in ideal parameters – what affects it?

Breakaway force was defined for optimal configuration, taking into account:
  • on a base made of structural steel, optimally conducting the magnetic flux
  • whose transverse dimension reaches at least 10 mm
  • with an polished contact surface
  • with zero gap (without paint)
  • under perpendicular force direction (90-degree angle)
  • at temperature approx. 20 degrees Celsius

Key elements affecting lifting force

Effective lifting capacity is influenced by working environment parameters, including (from most important):
  • Distance – existence of foreign body (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
  • Direction of force – maximum parameter is obtained only during perpendicular pulling. The force required to slide of the magnet along the surface is usually several times smaller (approx. 1/5 of the lifting capacity).
  • Element thickness – for full efficiency, the steel must be sufficiently thick. Paper-thin metal limits the lifting capacity (the magnet "punches through" it).
  • Steel type – mild steel gives the best results. Alloy admixtures lower magnetic properties and holding force.
  • Surface structure – the more even the surface, the larger the contact zone and higher the lifting capacity. Unevenness creates an air distance.
  • Thermal factor – hot environment weakens pulling force. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed with the use of a smooth steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a slight gap between the magnet’s surface and the plate reduces the lifting capacity.

Warnings
Implant safety

People with a heart stimulator must keep an large gap from magnets. The magnetism can interfere with the functioning of the implant.

Metal Allergy

Certain individuals suffer from a sensitization to Ni, which is the standard coating for neodymium magnets. Prolonged contact can result in an allergic reaction. We recommend wear protective gloves.

Protective goggles

Neodymium magnets are ceramic materials, meaning they are very brittle. Clashing of two magnets leads to them cracking into shards.

Thermal limits

Do not overheat. NdFeB magnets are sensitive to heat. If you require resistance above 80°C, ask us about HT versions (H, SH, UH).

Keep away from children

Neodymium magnets are not toys. Eating a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and requires immediate surgery.

Handling rules

Handle magnets consciously. Their powerful strength can surprise even experienced users. Be vigilant and do not underestimate their power.

Data carriers

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

Combustion hazard

Dust produced during grinding of magnets is flammable. Do not drill into magnets unless you are an expert.

Crushing risk

Large magnets can smash fingers instantly. Do not put your hand betwixt two strong magnets.

GPS Danger

An intense magnetic field negatively affects the functioning of compasses in smartphones and GPS navigation. Keep magnets near a device to avoid damaging the sensors.
