💡 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!

The main difference lies in the presence of two mounting holes (top and side). You can mount the eyelet on the side for shore casting or on top for bridge fishing. Single-mount magnets are less versatile when dragging from a riverbank.

Selecting the Dual version offers several advantages:
Double active surface: Increases the chance of catching items.
Greater adaptability: Adapt to any fishing condition.
Double power potential: The combined power of two F200 GOLD holders is nearly 600 kg.
Better durability: Lower risk of mechanical damage.
Great price-performance ratio: An economical choice for serious magnet fishers.

The F200 GOLD Dual is the best pick for magnet fishing enthusiasts seeking versatility.

It is worth betting on proven F200, F300, or F550 models from our offer, which guarantee real power. Model UMP 75x25 [M10x3] GW F200 GOLD DUAL Lina / N42 offers an optimal weight-to-pull force ratio, which is important for repeated throwing. 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. Side mounting is ideal for throwing from the shore, as the magnet drags flat along the bottom. 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. 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. A full set usually contains: magnet, polypropylene rope with appropriate strength, protective gloves, hook, and carabiner. 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. The magnet may slide on round elements (bicycle frame) due to the small contact area. 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.

In contrast to other brands, Dhit does not cut corners on materials, which translates into a clear advantage during every trip to the water.

The unique way of mounting the magnet in the protective cup builds a unified structure that dampens shocks while fishing on rough surfaces.

It is worth remembering that the identical magnet used by the lateral point can actually show as little as 40 kg of power instead of the promised 200 kg. The Dhit brand focuses on full transparency by providing the actual capabilities of the magnet, so you can be sure during treasure hunting.

{In contrast to competitors importing from China, Dhit provides expert advice and real warranty help, which is crucial after the purchase. Every mount is checked before shipping, which guarantees that you receive equipment of the highest quality.

Advantages and disadvantages of neodymium magnets.

Advantages

Besides their durability, neodymium magnets are valued for these benefits:

Their magnetic field is maintained, and after approximately 10 years it decreases only by ~1% (according to research),
Neodymium magnets prove to be exceptionally resistant to demagnetization caused by external field sources,
In other words, due to the shiny surface of gold, the element looks attractive,
Neodymium magnets create maximum magnetic induction on a their surface, which ensures high operational effectiveness,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the form) even at high temperatures reaching 230°C or more...
Possibility of individual forming and optimizing to atypical requirements,
Wide application in innovative solutions – they are utilized in hard drives, electric motors, advanced medical instruments, and technologically advanced constructions.
Relatively small size with high pulling force – neodymium magnets offer high power in compact dimensions, which makes them useful in miniature devices

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a steel housing, which not only secures them against impacts but also raises their durability
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their strength decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
They oxidize in a humid environment. For use outdoors we recommend using waterproof magnets e.g. in rubber, plastic
We recommend casing - magnetic mount, due to difficulties in producing threads inside the magnet and complex forms.
Health risk resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the context of child safety. Furthermore, tiny parts of these products can be problematic in diagnostics medical after entering the body.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Lifting parameters

Maximum lifting force for a neodymium magnet – what contributes to it?

Information about lifting capacity was determined for optimal configuration, assuming:

on a base made of structural steel, optimally conducting the magnetic flux
whose transverse dimension is min. 10 mm
with a surface perfectly flat
with total lack of distance (without impurities)
for force applied at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in practice – influencing factors

Effective lifting capacity is affected by working environment parameters, mainly (from priority):

Distance (betwixt the magnet and the plate), because even a tiny distance (e.g. 0.5 mm) results in a decrease in lifting capacity by up to 50% (this also applies to paint, corrosion or debris).
Force direction – declared lifting capacity refers to detachment vertically. When slipping, the magnet exhibits significantly lower power (often approx. 20-30% of maximum force).
Wall thickness – the thinner the sheet, the weaker the hold. Part of the magnetic field penetrates through instead of converting into lifting capacity.
Steel type – low-carbon steel attracts best. Alloy admixtures reduce magnetic properties and holding force.
Surface quality – the smoother and more polished the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Temperature influence – hot environment reduces magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed by applying a steel plate with a smooth surface of suitable thickness (min. 20 mm), under vertically applied force, whereas under parallel forces the load capacity is reduced by as much as 75%. Moreover, even a minimal clearance between the magnet and the plate reduces the lifting capacity.

Warnings

Handling guide

Use magnets with awareness. Their huge power can surprise even professionals. Be vigilant and do not underestimate their power.

Product not for children

Product intended for adults. Tiny parts can be swallowed, causing intestinal necrosis. Store out of reach of kids and pets.

Permanent damage

Control the heat. Heating the magnet to high heat will permanently weaken its properties and strength.

Fragile material

Neodymium magnets are sintered ceramics, meaning they are fragile like glass. Collision of two magnets leads to them cracking into shards.

Bone fractures

Big blocks can break fingers in a fraction of a second. Never put your hand between two attracting surfaces.

Warning for heart patients

For implant holders: Strong magnetic fields affect medical devices. Keep at least 30 cm distance or ask another person to handle the magnets.

GPS Danger

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

Magnetic media

Device Safety: Strong magnets can damage data carriers and sensitive devices (pacemakers, medical aids, mechanical watches).

Dust is flammable

Combustion risk: Rare earth powder is explosive. Avoid machining magnets in home conditions as this risks ignition.

Allergy Warning

Certain individuals experience a contact allergy to Ni, which is the common plating for neodymium magnets. Frequent touching may cause a rash. We suggest use protective gloves.

Important! Learn more about hazards in the article: Safety of working with magnets.
