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!

For underwater searches, we recommend specialized holders from the GOLD series, designed for working in difficult conditions. This specific magnet ensures a laboratory lifting capacity of up to 365.00 kg, which translates into high effectiveness in water. 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). The double-sided version increases search efficiency by 100%.

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. 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. A full set usually contains: magnet, polypropylene rope with appropriate strength, protective gloves, hook, and carabiner. 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. 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. 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 identical price, you buy a premium mount that will last for many seasons than generic imports.

A special technology of mounting the magnet in the Dhit housing creates a solid structure that absorbs impacts while fishing on rough surfaces.

You should know that the identical mount pulled by the lateral point often has as little as a fraction of power instead of the declared 200 kg. The Dhit brand focuses on full transparency by stating the real parameters of the magnet, so you can be sure during real field work.

{Unlike competitors importing from China, Dhit provides expert advice and instant warranty help, which gives peace of mind after the purchase. Every product is individually inspected before shipping, which ensures that you the set will be of the defect-free.

Pros and cons of rare earth magnets.

Pros

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They virtually do not lose strength, because even after ten years the decline in efficiency is only ~1% (according to literature),
They possess excellent resistance to magnetism drop as a result of external magnetic sources,
The use of an refined layer of noble metals (nickel, gold, silver) causes the element to look better,
Magnets possess very high magnetic induction on the outer layer,
Neodymium magnets are characterized by extremely high magnetic induction on the magnet surface and can function (depending on the shape) even at a temperature of 230°C or more...
Thanks to modularity in forming and the capacity to modify to client solutions,
Wide application in innovative solutions – they serve a role in data components, drive modules, diagnostic systems, and modern systems.
Relatively small size with high pulling force – neodymium magnets offer high power in tiny dimensions, which allows their use in small systems

Weaknesses

Disadvantages of NdFeB magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong 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 drop of strength (a factor is the shape and 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
Magnets exposed to a humid environment can corrode. Therefore during using outdoors, we suggest using water-impermeable magnets made of rubber, plastic or other material resistant to moisture
Due to limitations in realizing threads and complex shapes in magnets, we propose using cover - magnetic mount.
Possible danger resulting from small fragments of magnets can be dangerous, if swallowed, which becomes key in the aspect of protecting the youngest. Furthermore, tiny parts of these devices can complicate diagnosis medical in case of swallowing.
Higher cost of purchase is a significant factor to consider compared to ceramic magnets, especially in budget applications

Holding force characteristics

Best holding force of the magnet in ideal parameters – what affects it?

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

with the application of a sheet made of special test steel, ensuring maximum field concentration
with a thickness minimum 10 mm
with an polished touching surface
with total lack of distance (without paint)
under vertical application of breakaway force (90-degree angle)
at room temperature

Lifting capacity in real conditions – factors

It is worth knowing that the application force will differ depending on elements below, in order of importance:

Distance (betwixt the magnet and the plate), as even a tiny clearance (e.g. 0.5 mm) leads to a decrease in force by up to 50% (this also applies to varnish, corrosion or debris).
Angle of force application – maximum parameter is available only during pulling at a 90° angle. The shear force of the magnet along the plate is typically several times smaller (approx. 1/5 of the lifting capacity).
Wall thickness – thin material does not allow full use of the magnet. Magnetic flux passes through the material instead of generating force.
Steel grade – the best choice is pure iron steel. Stainless steels may have worse magnetic properties.
Surface condition – smooth surfaces guarantee perfect abutment, which increases field saturation. Rough surfaces reduce efficiency.
Heat – NdFeB sinters have a sensitivity to temperature. When it is hot they are weaker, and at low temperatures gain strength (up to a certain limit).

Lifting capacity testing was conducted on plates with a smooth surface of optimal thickness, under perpendicular forces, in contrast under attempts to slide the magnet the holding force is lower. Moreover, even a minimal clearance between the magnet’s surface and the plate decreases the lifting capacity.

H&S for magnets

Cards and drives

Intense magnetic fields can corrupt files on payment cards, HDDs, and other magnetic media. Stay away of min. 10 cm.

Fire warning

Mechanical processing of NdFeB material carries a risk of fire hazard. Magnetic powder reacts violently with oxygen and is hard to extinguish.

Compass and GPS

A strong magnetic field interferes with the operation of magnetometers in phones and navigation systems. Maintain magnets near a device to prevent damaging the sensors.

Allergy Warning

Certain individuals suffer from a contact allergy to nickel, which is the typical protective layer for neodymium magnets. Extended handling can result in skin redness. We suggest use protective gloves.

Bodily injuries

Big blocks can smash fingers in a fraction of a second. Do not put your hand between two attracting surfaces.

Shattering risk

Despite metallic appearance, the material is brittle and not impact-resistant. Do not hit, as the magnet may shatter into hazardous fragments.

Operating temperature

Do not overheat. Neodymium magnets are sensitive to temperature. If you need resistance above 80°C, look for special high-temperature series (H, SH, UH).

Danger to pacemakers

Warning for patients: Strong magnetic fields affect electronics. Keep at least 30 cm distance or ask another person to handle the magnets.

Do not underestimate power

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

Danger to the youngest

Product intended for adults. Small elements pose a choking risk, leading to intestinal necrosis. Store away from children and animals.
