💡 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 PLATINIUM / N52 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).

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.

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. 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). We often add thread glue to secure the eyelet against unscrewing in water. We recommend always securing the thread with glue or tightening the eyelet firmly before first use.

It is a technical parameter defining perpendicular break force, not the weight of an object in water. Dirt, rust, paint, and algae create a distance that weakens the magnet by even 70-80%. Therefore, to pull objects weighing 10kg from the water, a magnet with a capacity of 200-300kg is often needed.

Possessing and using a neodymium magnet to clean the bottom is generally legal, provided you are not searching for artifacts protected by law. We recommend familiarizing yourself with current local regulations and heritage protection laws.

In contrast to many market offers, Dhit uses the highest quality materials, which translates into a clear advantage during treasure hunting.

As a result, despite the market price, the lifespan of the GOLD mount puts it a step above the competition.

Many distributors employ a tactic by advertising the pull force tested only on the vertical mount. Interestingly, in the web, there are virtually no recordings testing the actual strength of other brands on the side hook.

{In contrast to anonymous sellers, Dhit provides full support and real warranty help, which gives peace of mind after the purchase. Instead of risking with unknown goods, it is better to choose proven gear that cares about the happiness of every user.

Strengths as well as weaknesses of neodymium magnets.

Benefits

Besides their remarkable pulling force, neodymium magnets offer the following advantages:

Their strength remains stable, and after approximately ten years it decreases only by ~1% (according to research),
They feature excellent resistance to magnetism drop when exposed to external magnetic sources,
Thanks to the reflective finish, the layer of Ni-Cu-Ni, gold-plated, or silver-plated gives an aesthetic appearance,
Neodymium magnets deliver maximum magnetic induction on a their surface, which increases force concentration,
Thanks to resistance to high temperature, they are capable of working (depending on the form) even at temperatures up to 230°C and higher...
Thanks to flexibility in constructing and the capacity to customize to complex applications,
Fundamental importance in high-tech industry – they find application in data components, electric motors, medical devices, and industrial machines.
Thanks to concentrated force, small magnets offer high operating force, with minimal size,

Limitations

What to avoid - cons of neodymium magnets and ways of using them

They are fragile upon too strong impacts. To avoid cracks, it is worth protecting magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we recommend our specialized [AH] magnets, which work effectively even at 230°C.
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material stable to moisture, in case of application outdoors
We recommend a housing - magnetic holder, due to difficulties in creating threads inside the magnet and complex shapes.
Potential hazard related to microscopic parts of magnets pose a threat, when accidentally swallowed, which is particularly important in the aspect of protecting the youngest. Additionally, small elements of these products can complicate diagnosis medical after entering the body.
Due to complex production process, their price exceeds standard values,

Pull force analysis

Maximum holding power of the magnet – what affects it?

Holding force of 365.00 kg is a result of laboratory testing conducted under specific, ideal conditions:

using a base made of mild steel, functioning as a ideal flux conductor
whose thickness equals approx. 10 mm
with an ideally smooth touching surface
without the slightest clearance between the magnet and steel
for force applied at a right angle (pull-off, not shear)
at ambient temperature approx. 20 degrees Celsius

Lifting capacity in real conditions – factors

Please note that the application force may be lower depending on elements below, in order of importance:

Space between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) diminishes the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under shear forces, the capacity drops significantly, often to levels of 20-30% of the nominal value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Metal type – not every steel attracts identically. High carbon content worsen the interaction with the magnet.
Smoothness – ideal contact is obtained only on polished steel. Rough texture reduce the real contact area, weakening the magnet.
Thermal factor – hot environment reduces magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was conducted on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under shearing force the holding force is lower. Additionally, even a small distance between the magnet and the plate decreases the holding force.

Safety rules for work with neodymium magnets

Serious injuries

Pinching hazard: The pulling power is so immense that it can cause hematomas, crushing, and broken bones. Protective gloves are recommended.

Implant safety

Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or ask another person to work with the magnets.

Beware of splinters

Protect your eyes. Magnets can explode upon uncontrolled impact, ejecting shards into the air. Wear goggles.

Do not underestimate power

Before starting, read the rules. Sudden snapping can destroy the magnet or hurt your hand. Be predictive.

Fire risk

Drilling and cutting of NdFeB material carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Danger to the youngest

Product intended for adults. Small elements can be swallowed, leading to severe trauma. Keep out of reach of kids and pets.

Compass and GPS

A strong magnetic field interferes with the operation of compasses in smartphones and GPS navigation. Maintain magnets close to a device to avoid damaging the sensors.

Protect data

Very strong magnetic fields can erase data on payment cards, HDDs, and storage devices. Stay away of min. 10 cm.

Heat sensitivity

Keep cool. NdFeB magnets are susceptible to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Warning for allergy sufferers

Warning for allergy sufferers: The Ni-Cu-Ni coating consists of nickel. If an allergic reaction occurs, cease handling magnets and wear gloves.
