💡 Guide: How to choose a decent magnet and not get ripped off?

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!

It is worth betting on proven F200, F300, or F550 models from our offer, which guarantee real power. Model UMP 75x25 [M10x3] GW F200 PLATINIUM / N52 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 double-sided model attracts from above and below, increasing the chance of hooking a find. The side eyelet ensures the magnet doesn't stand sideways or "on edge" during pulling. The double-sided version increases search efficiency by 100%.
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. In the package, you will find everything needed: strong rope (e.g., 20m), gloves, and hardware. 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. In a river, objects are often rusty, silted, or irregular in shape (e.g., pipes), which drastically reduces grip strength. A large power reserve is essential in real search conditions.
Searches are allowed as long as you do not interfere with archaeological sites or search for weapons. We recommend familiarizing yourself with current local regulations and heritage protection laws.
It is the best value because for the identical price, you buy a premium mount that will last for much longer than budget alternatives.
As a result, despite the affordable cost, the lifespan of the Dhit product positions it a step above other brands.
It is worth remembering that the identical magnet pulled by the lateral point often has only 40 kg of strength instead of the declared 200 kg. Crucially, in the entire internet, it is hard to find recordings testing the actual strength of competitor products on the side hook.
{Unlike competitors importing from China, Dhit provides full support and instant warranty help, which gives peace of mind after the purchase. Instead of risking with unknown goods, it is better to choose the market leader that cares about the happiness of searcher.

Strengths as well as weaknesses of Nd2Fe14B magnets.

Pros

Apart from their superior power, neodymium magnets have these key benefits:
  • They virtually do not lose power, because even after 10 years the performance loss is only ~1% (based on calculations),
  • Neodymium magnets remain highly resistant to magnetic field loss caused by external magnetic fields,
  • Thanks to the shiny finish, the surface of nickel, gold-plated, or silver gives an professional appearance,
  • They show high magnetic induction at the operating surface, which increases their power,
  • Made from properly selected components, these magnets show impressive resistance to high heat, enabling them to function (depending on their shape) at temperatures up to 230°C and above...
  • Thanks to flexibility in constructing and the capacity to adapt to client solutions,
  • Huge importance in future technologies – they are used in HDD drives, electric drive systems, diagnostic systems, also modern systems.
  • Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which makes them useful in compact constructions

Cons

Problematic aspects of neodymium magnets and proposals for their use:
  • They are fragile upon too strong impacts. To avoid cracks, it is worth securing magnets using a steel holder. Such protection not only protects the magnet but also increases its resistance to damage
  • 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 those in rubber or plastics, which secure oxidation and corrosion.
  • We suggest casing - magnetic holder, due to difficulties in realizing threads inside the magnet and complex forms.
  • Possible danger to health – tiny shards of magnets can be dangerous, if swallowed, which gains importance in the context of child safety. It is also worth noting that tiny parts of these devices are able to complicate diagnosis medical after entering the body.
  • Due to neodymium price, their price is higher than average,

Holding force characteristics

Breakaway strength of the magnet in ideal conditions – what contributes to it?

Information about lifting capacity was defined for the most favorable conditions, assuming:
  • using a sheet made of high-permeability steel, functioning as a circuit closing element
  • possessing a massiveness of min. 10 mm to ensure full flux closure
  • with a plane perfectly flat
  • without the slightest clearance between the magnet and steel
  • for force acting at a right angle (in the magnet axis)
  • at ambient temperature room level

What influences lifting capacity in practice

Holding efficiency is affected by specific conditions, including (from most important):
  • Distance – existence of any layer (paint, tape, gap) interrupts the magnetic circuit, which reduces capacity steeply (even by 50% at 0.5 mm).
  • Force direction – declared lifting capacity refers to pulling vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of maximum force).
  • Plate thickness – insufficiently thick sheet does not close the flux, causing part of the power to be lost to the other side.
  • Steel grade – the best choice is pure iron steel. Stainless steels may attract less.
  • Surface structure – the smoother and more polished the surface, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
  • Operating temperature – neodymium magnets 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 testing was conducted on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under shearing force the holding force is lower. Additionally, even a slight gap between the magnet’s surface and the plate lowers the load capacity.

H&S for magnets
Flammability

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

GPS and phone interference

A powerful magnetic field negatively affects the functioning of compasses in phones and GPS navigation. Keep magnets close to a smartphone to prevent damaging the sensors.

Medical interference

Warning for patients: Strong magnetic fields disrupt medical devices. Keep at least 30 cm distance or request help to handle the magnets.

Allergic reactions

A percentage of the population suffer from a sensitization to Ni, which is the common plating for NdFeB magnets. Frequent touching may cause skin redness. We suggest wear protective gloves.

Swallowing risk

Only for adults. Small elements pose a choking risk, leading to severe trauma. Keep away from children and animals.

Hand protection

Mind your fingers. Two powerful magnets will join immediately with a force of several hundred kilograms, crushing everything in their path. Exercise extreme caution!

Magnets are brittle

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

Immense force

Before starting, check safety instructions. Sudden snapping can destroy the magnet or injure your hand. Be predictive.

Permanent damage

Standard neodymium magnets (grade N) lose power when the temperature goes above 80°C. The loss of strength is permanent.

Electronic devices

Data protection: Strong magnets can damage data carriers and sensitive devices (pacemakers, hearing aids, timepieces).
