💡 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!

For underwater searches, we recommend specialized holders from the GOLD series, designed for working in difficult conditions. It is equipment that can handle pulling heavy and silted objects from the river bottom. 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. 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. The housing significantly increases lifespan but does not make the magnet completely indestructible. After each fishing trip, we recommend rinsing the magnet with fresh water and drying it.

Check the product title and description to see if you are buying just the magnet or the XL set. We often add thread glue to secure the eyelet against unscrewing in water. Using thread glue is crucial to not lose the magnet in silt.

The capacity given in the name (e.g., 310.00 kg) is the maximum value measured in laboratory conditions. In a river, objects are often rusty, silted, or irregular in shape (e.g., pipes), which drastically reduces grip strength. 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. It is worth acting responsibly, cleaning up after yourself, and caring for the environment by removing fished-out scrap.

It is the best value because for the same money, you obtain a premium mount that will serve you for much longer than budget alternatives.

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

You should know that the same mount pulled by the side hook can actually show only 40 kg of strength instead of the declared 200 kg. Crucially, in the web, there are virtually no videos demonstrating the actual strength of competitor products on the side hook.

{By choosing Dhit, you support Polish engineering that knows the specifics of our waters. Every mount is checked before delivery, which ensures that you the set will be of the highest quality.

Strengths as well as weaknesses of Nd₂Fe₁₄B magnets.

Advantages

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

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
They show high resistance to demagnetization induced by external magnetic fields,
By applying a decorative layer of silver, the element acquires an nice look,
Magnets have exceptionally strong magnetic induction on the active area,
Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their form) at temperatures up to 230°C and above...
Possibility of exact shaping as well as modifying to precise conditions,
Wide application in electronics industry – they serve a role in magnetic memories, motor assemblies, medical equipment, also multitasking production systems.
Relatively small size with high pulling force – neodymium magnets offer impressive pulling force in compact dimensions, which makes them useful in compact constructions

Disadvantages

Disadvantages of NdFeB magnets:

To avoid cracks under impact, we suggest using special steel housings. Such a solution protects the magnet and simultaneously increases its durability.
We warn that neodymium magnets can reduce their strength at high temperatures. To prevent this, we suggest our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation and corrosion.
We recommend casing - magnetic mount, due to difficulties in creating nuts inside the magnet and complicated forms.
Potential hazard to health – tiny shards of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these devices can complicate diagnosis medical in case of swallowing.
Due to expensive raw materials, their price is relatively high,

Lifting parameters

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

The declared magnet strength concerns the limit force, obtained under ideal test conditions, meaning:

on a block made of mild steel, perfectly concentrating the magnetic field
with a cross-section no less than 10 mm
with a plane cleaned and smooth
under conditions of gap-free contact (surface-to-surface)
for force acting at a right angle (pull-off, not shear)
at conditions approx. 20°C

Magnet lifting force in use – key factors

In practice, the actual holding force results from a number of factors, ranked from the most important:

Gap between magnet and steel – even a fraction of a millimeter of distance (caused e.g. by veneer or dirt) significantly weakens the magnet efficiency, often by half at just 0.5 mm.
Force direction – note that the magnet has greatest strength perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Substrate thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet restricts the lifting capacity (the magnet "punches through" it).
Material composition – different alloys attracts identically. High carbon content worsen the attraction effect.
Plate texture – ground elements ensure maximum contact, which increases field saturation. Rough surfaces weaken the grip.
Thermal environment – heating the magnet results in weakening of induction. Check the thermal limit for a given model.

Holding force was checked on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the holding force is lower. In addition, even a small distance between the magnet and the plate reduces the load capacity.

Safe handling of neodymium magnets

Safe distance

Device Safety: Neodymium magnets can damage data carriers and delicate electronics (heart implants, medical aids, timepieces).

Allergy Warning

Nickel alert: The nickel-copper-nickel coating contains nickel. If skin irritation appears, cease handling magnets and use protective gear.

Shattering risk

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

Keep away from electronics

A strong magnetic field disrupts the functioning of magnetometers in phones and navigation systems. Do not bring magnets near a smartphone to prevent damaging the sensors.

Medical interference

Life threat: Neodymium magnets can deactivate heart devices and defibrillators. Do not approach if you have medical devices.

Safe operation

Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and respect their power.

Crushing risk

Large magnets can break fingers in a fraction of a second. Do not place your hand between two strong magnets.

This is not a toy

Strictly store magnets away from children. Choking hazard is high, and the consequences of magnets connecting inside the body are fatal.

Combustion hazard

Fire hazard: Rare earth powder is explosive. Do not process magnets without safety gear as this may cause fire.

Thermal limits

Standard neodymium magnets (grade N) undergo demagnetization when the temperature exceeds 80°C. Damage is permanent.

Security! Details about risks in the article: Magnet Safety Guide.
