💡 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 best choice are magnets in thick, chrome-plated housings dedicated to water applications. Model UMP 75x25 [M10x3] GW F200 GOLD DUAL / N42 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.

Double-sided holders (Two-Side) have two active magnetic surfaces and two mounting holes. 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.

This construction protects the brittle neodymium from direct impact against stones and the bottom. Despite solid construction, neodymium is a brittle material and can chip upon very strong impact (e.g., against concrete). After each fishing trip, we recommend rinsing the magnet with fresh water and drying it.

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. Using thread glue is crucial to not lose the magnet in silt.

The capacity given in the name (e.g., 601.00 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.

By choosing the Dhit brand, you receive a product of a significantly higher standard and real N52 grade for the average cost.

The GOLD series utilize heavy-duty, thick-walled steel that provides a true shield for the brittle neodymium.

It is worth remembering that the same mount used by the lateral point can actually show only 40 kg of strength instead of the promised 200 kg. The Dhit brand focuses on honest data by providing the actual capabilities of the gear, so you can be sure during real field work.

{By choosing GOLD mounts, you support a local market leader that knows the specifics of our waters. Instead of risking with unknown goods, it is better to choose the market leader that ensures the happiness of every user.

Pros as well as cons of neodymium magnets.

Strengths

In addition to their magnetic efficiency, neodymium magnets provide the following advantages:

They retain magnetic properties for around 10 years – the drop is just ~1% (in theory),
Neodymium magnets are highly resistant to magnetic field loss caused by external interference,
The use of an refined finish of noble metals (nickel, gold, silver) causes the element to look better,
Magnetic induction on the working layer of the magnet is very high,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Possibility of accurate machining as well as modifying to concrete applications,
Versatile presence in modern industrial fields – they are used in data components, drive modules, advanced medical instruments, as well as industrial machines.
Compactness – despite small sizes they offer powerful magnetic field, making them ideal for precision applications

Weaknesses

Disadvantages of neodymium magnets:

They are prone to damage upon heavy impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only protects the magnet but also improves its resistance to damage
When exposed to high temperature, neodymium magnets suffer a drop in power. Often, when the temperature exceeds 80°C, their power 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 - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest cover - magnetic holder, due to difficulties in producing nuts inside the magnet and complicated shapes.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, tiny parts of these magnets are able to be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which can limit application in large quantities

Holding force characteristics

Detachment force of the magnet in optimal conditions – what affects it?

Holding force of 601.00 kg is a measurement result conducted under specific, ideal conditions:

using a plate made of low-carbon steel, serving as a magnetic yoke
with a thickness no less than 10 mm
characterized by lack of roughness
with zero gap (no coatings)
during detachment in a direction vertical to the plane
at conditions approx. 20°C

Practical lifting capacity: influencing factors

In real-world applications, the actual holding force is determined by many variables, listed from the most important:

Space between magnet and steel – every millimeter of separation (caused e.g. by veneer or unevenness) diminishes the pulling force, often by half at just 0.5 mm.
Force direction – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – to utilize 100% power, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Material composition – not every steel attracts identically. Alloy additives weaken the attraction effect.
Plate texture – smooth surfaces guarantee perfect abutment, which improves field saturation. Rough surfaces weaken the grip.
Heat – NdFeB sinters have a negative temperature coefficient. When it is hot they are weaker, and in frost they can be stronger (up to a certain limit).

Lifting capacity was assessed with the use of a steel plate with a smooth surface of suitable thickness (min. 20 mm), under perpendicular pulling force, in contrast under parallel forces the load capacity is reduced by as much as fivefold. Additionally, even a small distance between the magnet and the plate decreases the lifting capacity.

Safe handling of neodymium magnets

Pacemakers

Patients with a pacemaker must keep an large gap from magnets. The magnetic field can stop the operation of the implant.

Magnet fragility

Despite metallic appearance, neodymium is delicate and cannot withstand shocks. Avoid impacts, as the magnet may shatter into hazardous fragments.

Physical harm

Protect your hands. Two large magnets will snap together immediately with a force of massive weight, destroying anything in their path. Be careful!

Data carriers

Do not bring magnets close to a wallet, computer, or TV. The magnetism can destroy these devices and wipe information from cards.

GPS and phone interference

Be aware: rare earth magnets generate a field that disrupts precision electronics. Keep a separation from your phone, tablet, and GPS.

Dust is flammable

Machining of NdFeB material carries a risk of fire risk. Neodymium dust oxidizes rapidly with oxygen and is difficult to extinguish.

Do not overheat magnets

Watch the temperature. Heating the magnet to high heat will ruin its properties and strength.

Caution required

Handle magnets consciously. Their immense force can shock even professionals. Be vigilant and respect their force.

Allergic reactions

A percentage of the population suffer from a contact allergy to Ni, which is the common plating for neodymium magnets. Prolonged contact may cause a rash. We recommend wear protective gloves.

No play value

Strictly store magnets out of reach of children. Ingestion danger is significant, and the effects of magnets connecting inside the body are tragic.
