💡 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!

The main difference lies in the presence of two mounting holes (top and side). This allows for searching both vertically (from a bridge) and horizontally (from the shore). Single-mount magnets are less versatile when dragging from a riverbank.

Here is why the Double version is a great choice:
Larger contact area: More space to attract objects.
Greater adaptability: Possibility to use two mounts separately or together.
Greater combined force: Theoretically, it offers double the attracting area.
Robustness: Solid construction.
Great price-performance ratio: An economical choice for serious magnet fishers.

The F200 GOLD Dual is the best pick for magnet fishing enthusiasts seeking versatility.

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. 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. The side eyelet ensures the magnet doesn't stand sideways or "on edge" during pulling. 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). The housing significantly increases lifespan but does not make the magnet completely indestructible. Maintenance (e.g., WD-40) prevents surface corrosion of the steel housing.

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

The capacity given in the name (e.g., 601.00 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 smartest investment because for the same money, you buy a premium mount that will last for many seasons than generic imports.

As a result, despite the affordable cost, the mechanical durability of the GOLD mount positions it far ahead of the competition.

Many sellers employ a tactic by promoting the power measured only on the vertical mount. 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 anonymous sellers, Dhit provides full support and real warranty help, which is crucial after the purchase. Every product is checked before delivery, which ensures that you the set will be of the defect-free.

Pros as well as cons of neodymium magnets.

Pros

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

They do not lose magnetism, even over approximately 10 years – the decrease in power is only ~1% (based on measurements),
Magnets effectively defend themselves against loss of magnetization caused by external fields,
In other words, due to the shiny finish of nickel, the element becomes visually attractive,
Neodymium magnets create maximum magnetic induction on a contact point, which allows for strong attraction,
Through (adequate) combination of ingredients, they can achieve high thermal resistance, enabling operation at temperatures reaching 230°C and above...
Possibility of precise machining and adjusting to atypical conditions,
Significant place in modern technologies – they serve a role in magnetic memories, electromotive mechanisms, advanced medical instruments, and complex engineering applications.
Thanks to their power density, small magnets offer high operating force, occupying minimum space,

Disadvantages

Problematic aspects of neodymium magnets: application proposals

They are fragile upon heavy impacts. To avoid cracks, it is worth securing magnets in special housings. Such protection not only shields the magnet but also improves its resistance to damage
NdFeB magnets lose strength when exposed to high temperatures. After reaching 80°C, many of them experience permanent drop 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 extremely resistant to heat
Due to the susceptibility of magnets to corrosion in a humid environment, we advise using waterproof magnets made of rubber, plastic or other material immune to moisture, when using outdoors
We recommend cover - magnetic mechanism, due to difficulties in realizing threads inside the magnet and complicated forms.
Potential hazard resulting from small fragments of magnets are risky, when accidentally swallowed, which is particularly important in the context of child health protection. Furthermore, small components of these magnets are able to be problematic in diagnostics medical after entering the body.
With budget limitations the cost of neodymium magnets is a challenge,

Pull force analysis

Maximum lifting capacity of the magnet – what affects it?

The lifting capacity listed is a theoretical maximum value executed under standard conditions:

using a base made of low-carbon steel, acting as a circuit closing element
whose thickness equals approx. 10 mm
with an polished contact surface
with total lack of distance (without coatings)
for force acting at a right angle (in the magnet axis)
in stable room temperature

Lifting capacity in real conditions – factors

In practice, the real power is determined by a number of factors, listed from crucial:

Clearance – the presence of any layer (rust, dirt, air) acts as an insulator, which lowers power steeply (even by 50% at 0.5 mm).
Pull-off angle – note that the magnet holds strongest perpendicularly. Under shear forces, the holding force drops significantly, often to levels of 20-30% of the maximum value.
Base massiveness – too thin steel does not accept the full field, causing part of the flux to be wasted into the air.
Material composition – not every steel attracts identically. High carbon content weaken the attraction effect.
Base smoothness – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness acts like micro-gaps.
Temperature influence – high temperature weakens magnetic field. Exceeding the limit temperature can permanently demagnetize the magnet.

Lifting capacity was assessed using a smooth steel plate of suitable thickness (min. 20 mm), under vertically applied force, however under attempts to slide the magnet the lifting capacity is smaller. In addition, even a slight gap between the magnet and the plate decreases the holding force.

Safety rules for work with NdFeB magnets

Power loss in heat

Do not overheat. NdFeB magnets are sensitive to heat. If you need operation above 80°C, ask us about HT versions (H, SH, UH).

Phone sensors

Navigation devices and mobile phones are highly susceptible to magnetism. Close proximity with a strong magnet can decalibrate the internal compass in your phone.

Avoid contact if allergic

A percentage of the population experience a contact allergy to Ni, which is the typical protective layer for NdFeB magnets. Extended handling may cause an allergic reaction. We recommend use protective gloves.

Medical implants

People with a heart stimulator should maintain an large gap from magnets. The magnetism can stop the functioning of the life-saving device.

Dust explosion hazard

Dust created during machining of magnets is combustible. Avoid drilling into magnets without proper cooling and knowledge.

Magnet fragility

Beware of splinters. Magnets can explode upon violent connection, launching shards into the air. We recommend safety glasses.

Crushing force

Mind your fingers. Two powerful magnets will snap together instantly with a force of several hundred kilograms, crushing anything in their path. Exercise extreme caution!

Swallowing risk

Strictly store magnets out of reach of children. Ingestion danger is high, and the effects of magnets clamping inside the body are very dangerous.

Magnetic media

Do not bring magnets near a purse, laptop, or screen. The magnetism can destroy these devices and wipe information from cards.

Immense force

Handle magnets consciously. Their huge power can shock even experienced users. Be vigilant and do not underestimate their power.
