💡 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. It is equipment that can handle pulling heavy and silted objects from the river bottom. 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. Side mounting is ideal for throwing from the shore, as the magnet drags flat along the bottom. The double-sided version increases search efficiency by 100%.

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

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

This force applies to perfect adherence with the entire surface to a smooth, clean steel plate with a min. thickness of 20mm. 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.

Searches are allowed as long as you do not interfere with archaeological sites or search for weapons. Magnet fishing is an eco-friendly hobby if you clean the river from trash and scrap.

It is the best value because for the same money, you buy a premium mount that will last for many seasons than generic imports.

Most competitor mounts have thin casings that deform during the any strong impact against concrete or rocks.

You should know that the same magnet used by the side hook often has only a fraction of strength instead of the promised 200 kg. Interestingly, in the web, it is hard to find recordings testing the actual strength of competitor products on the side hook.

{In contrast to competitors importing from China, Dhit provides expert advice and real warranty help, which is crucial after the transaction. Instead of risking with unknown goods, it is better to choose proven gear that cares about the satisfaction of every user.

Advantages and disadvantages of Nd₂Fe₁₄B magnets.

Pros

In addition to their long-term stability, neodymium magnets provide the following advantages:

They retain full power for around ten years – the drop is just ~1% (according to analyses),
They have excellent resistance to weakening of magnetic properties due to external magnetic sources,
A magnet with a smooth gold surface is more attractive,
They feature high magnetic induction at the operating surface, which improves attraction properties,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Thanks to the ability of accurate molding and adaptation to custom projects, neodymium magnets can be modeled in a variety of forms and dimensions, which makes them more universal,
Versatile presence in modern industrial fields – they find application in computer drives, brushless drives, medical devices, also multitasking production systems.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Weaknesses

Cons of neodymium magnets and proposals for their use:

At strong impacts they can break, therefore we advise placing them in special holders. A metal housing provides additional protection against damage and increases the magnet's durability.
Neodymium magnets demagnetize when exposed to high temperatures. After reaching 80°C, many of them experience permanent weakening of strength (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 extremely resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic or other material immune to moisture, in case of application outdoors
Due to limitations in producing threads and complicated shapes in magnets, we recommend using a housing - magnetic holder.
Potential hazard resulting from small fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the aspect of protecting the youngest. Furthermore, small elements of these magnets can disrupt the diagnostic process medical after entering the body.
High unit price – neodymium magnets have a higher price than other types of magnets (e.g. ferrite), which hinders application in large quantities

Holding force characteristics

Maximum magnetic pulling force – what contributes to it?

Information about lifting capacity was determined for ideal contact conditions, including:

using a base made of low-carbon steel, functioning as a magnetic yoke
whose transverse dimension reaches at least 10 mm
with a surface cleaned and smooth
without the slightest insulating layer between the magnet and steel
under vertical force direction (90-degree angle)
at room temperature

Determinants of lifting force in real conditions

Real force is affected by specific conditions, such as (from most important):

Clearance – the presence of any layer (paint, dirt, gap) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Angle of force application – highest force is obtained only during pulling at a 90° angle. The force required to slide of the magnet along the surface is typically many times lower (approx. 1/5 of the lifting capacity).
Metal thickness – the thinner the sheet, the weaker the hold. Magnetic flux passes through the material instead of generating force.
Steel grade – the best choice is high-permeability steel. Stainless steels may have worse magnetic properties.
Plate texture – ground elements guarantee perfect abutment, which increases field saturation. Rough surfaces weaken the grip.
Temperature – heating the magnet causes a temporary drop of induction. Check the maximum operating temperature for a given model.

Holding force was checked on the plate surface of 20 mm thickness, when the force acted perpendicularly, whereas under parallel forces the load capacity is reduced by as much as 75%. Additionally, even a small distance between the magnet and the plate reduces the load capacity.

Warnings

Flammability

Machining of neodymium magnets carries a risk of fire risk. Neodymium dust reacts violently with oxygen and is hard to extinguish.

Health Danger

People with a heart stimulator should maintain an safe separation from magnets. The magnetism can stop the operation of the life-saving device.

Demagnetization risk

Do not overheat. Neodymium magnets are susceptible to temperature. If you require operation above 80°C, ask us about HT versions (H, SH, UH).

Magnets are brittle

Protect your eyes. Magnets can explode upon violent connection, launching sharp fragments into the air. We recommend safety glasses.

Adults only

Always keep magnets away from children. Risk of swallowing is significant, and the consequences of magnets connecting inside the body are very dangerous.

Nickel allergy

A percentage of the population suffer from a hypersensitivity to nickel, which is the typical protective layer for NdFeB magnets. Frequent touching can result in an allergic reaction. We suggest wear protective gloves.

Compass and GPS

An intense magnetic field disrupts the functioning of compasses in phones and GPS navigation. Maintain magnets close to a smartphone to avoid damaging the sensors.

Do not underestimate power

Handle magnets with awareness. Their powerful strength can shock even professionals. Plan your moves and do not underestimate their force.

Electronic hazard

Powerful magnetic fields can destroy records on payment cards, HDDs, and other magnetic media. Keep a distance of at least 10 cm.

Bone fractures

Risk of injury: The pulling power is so immense that it can cause hematomas, pinching, and broken bones. Use thick gloves.
