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

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. 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. The side eyelet ensures the magnet doesn't stand sideways or "on edge" during pulling. Single-sided magnets are usually lighter and cheaper but less effective for long throws.

Our holders have a thick steel housing covered with an anti-corrosion layer (chrome, nickel, zinc). 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.

Most of our starter kits are complete and ready to use. 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%. 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.

In contrast to other brands, Dhit uses the highest quality materials, which translates into a clear advantage during every trip to the water.

Dhit GOLD mounts utilize heavy-duty, thick-walled steel that provides a true shield for the magnetic core.

You should know that the identical magnet used by the lateral point often has as little as 40 kg of power instead of the declared 200 kg. Crucially, in the entire internet, it is hard to find videos testing the actual strength of other brands on the lateral attachment.

{In contrast to anonymous sellers, Dhit provides expert advice and real service assistance, which gives peace of mind after the transaction. Don't risk it with random brands, it is better to choose the market leader that ensures the satisfaction of searcher.

Strengths and weaknesses of neodymium magnets.

Benefits

Besides their exceptional magnetic power, neodymium magnets offer the following advantages:

They do not lose magnetism, even after nearly 10 years – the decrease in strength is only ~1% (according to tests),
They are resistant to demagnetization induced by external disturbances,
Thanks to the metallic finish, the surface of nickel, gold, or silver gives an professional appearance,
The surface of neodymium magnets generates a intense magnetic field – this is a distinguishing feature,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to modularity in designing and the ability to modify to client solutions,
Versatile presence in modern technologies – they serve a role in hard drives, electric motors, advanced medical instruments, as well as industrial machines.
Thanks to their power density, small magnets offer high operating force, with minimal size,

Cons

Disadvantages of NdFeB magnets:

Brittleness is one of their disadvantages. Upon intense impact they can fracture. We advise keeping them in a special holder, which not only secures them against impacts but also increases their durability
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of power (a factor is the shape as well as dimensions of the magnet). We offer magnets specially adapted to work at temperatures up to 230°C marked [AH], which are very resistant to heat
They rust in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
We suggest a housing - magnetic mechanism, due to difficulties in producing nuts inside the magnet and complex shapes.
Health risk related to microscopic parts of magnets pose a threat, when accidentally swallowed, which gains importance in the context of child safety. It is also worth noting that small components of these devices are able to be problematic in diagnostics medical in case of swallowing.
High unit price – neodymium magnets are more expensive than other types of magnets (e.g. ferrite), which hinders application in large quantities

Lifting parameters

Magnetic strength at its maximum – what affects it?

Breakaway force was defined for ideal contact conditions, including:

with the contact of a yoke made of special test steel, guaranteeing full magnetic saturation
whose thickness is min. 10 mm
characterized by lack of roughness
without any clearance between the magnet and steel
during pulling in a direction perpendicular to the mounting surface
at standard ambient temperature

Lifting capacity in practice – influencing factors

It is worth knowing that the application force will differ influenced by the following factors, starting with the most relevant:

Space between surfaces – even a fraction of a millimeter of distance (caused e.g. by varnish or unevenness) drastically reduces the magnet efficiency, often by half at just 0.5 mm.
Force direction – remember that the magnet has greatest strength perpendicularly. Under sliding down, the holding force drops drastically, often to levels of 20-30% of the nominal value.
Steel thickness – insufficiently thick plate does not close the flux, causing part of the flux to be escaped to the other side.
Steel type – low-carbon steel gives the best results. Alloy admixtures reduce magnetic properties and lifting capacity.
Surface quality – the more even the surface, the larger the contact zone and higher the lifting capacity. Roughness creates an air distance.
Temperature – heating the magnet results in weakening of force. Check the maximum operating temperature for a given model.

Lifting capacity was assessed by applying a smooth steel plate of suitable thickness (min. 20 mm), under perpendicular detachment force, however under parallel forces the holding force is lower. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the holding force.

Precautions when working with neodymium magnets

Finger safety

Protect your hands. Two large magnets will join instantly with a force of several hundred kilograms, crushing anything in their path. Be careful!

Magnetic interference

A powerful magnetic field negatively affects the operation of magnetometers in phones and navigation systems. Maintain magnets near a smartphone to avoid breaking the sensors.

This is not a toy

Only for adults. Tiny parts pose a choking risk, causing severe trauma. Keep away from kids and pets.

Maximum temperature

Regular neodymium magnets (grade N) lose magnetization when the temperature exceeds 80°C. This process is irreversible.

Protective goggles

Watch out for shards. Magnets can explode upon violent connection, ejecting sharp fragments into the air. Eye protection is mandatory.

Respect the power

Before use, check safety instructions. Sudden snapping can destroy the magnet or hurt your hand. Think ahead.

Danger to pacemakers

Medical warning: Strong magnets can deactivate heart devices and defibrillators. Do not approach if you have electronic implants.

Do not drill into magnets

Machining of NdFeB material poses a fire hazard. Magnetic powder reacts violently with oxygen and is difficult to extinguish.

Protect data

Data protection: Neodymium magnets can damage data carriers and delicate electronics (pacemakers, hearing aids, mechanical watches).

Allergic reactions

Certain individuals experience a hypersensitivity to Ni, which is the typical protective layer for NdFeB magnets. Prolonged contact might lead to dermatitis. We recommend use protective gloves.

Security! Learn more about hazards in the article: Magnet Safety Guide.
