💡 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!

For underwater searches, we recommend specialized holders from the GOLD series, designed for working in difficult conditions. 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).

The 2xTwo-Side version is more versatile, allowing the eyelet to be mounted in two positions. Top mounting works well when fishing from a bridge, pier, or well (vertical technique). Single-sided magnets are usually lighter and cheaper but less effective for long throws.

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. We often add thread glue to secure the eyelet against unscrewing in water. Using thread glue is crucial to not lose the magnet in silt.

It is a technical parameter defining perpendicular break force, not the weight of an object in water. 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.

Possessing and using a neodymium magnet to clean the bottom is generally legal, provided you are not searching for artifacts protected by law. We recommend familiarizing yourself with current local regulations and heritage protection laws.

By selecting Dhit GOLD mounts, you receive a higher quality standard and true magnetic power for the same market price.

Most magnets on the market have weak shells that deform during the any strong impact against concrete or rocks.

Many distributors use a trick by advertising the pull force measured only on the top hook. GOLD mounts focuses on honest data by providing the real parameters of the gear, so you can be sure during treasure hunting.

{Unlike anonymous sellers, Dhit provides expert advice and real warranty help, which gives peace of mind after the purchase. Every product is individually inspected before shipping, which guarantees that you receive equipment of the highest quality.

Advantages as well as disadvantages of rare earth magnets.

Advantages

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

They retain full power for almost ten years – the loss is just ~1% (based on simulations),
They do not lose their magnetic properties even under strong external field,
The use of an refined coating of noble metals (nickel, gold, silver) causes the element to be more visually attractive,
Neodymium magnets generate maximum magnetic induction on a small area, which ensures high operational effectiveness,
Due to their durability and thermal resistance, neodymium magnets are capable of operate (depending on the form) even at high temperatures reaching 230°C or more...
Thanks to flexibility in constructing and the capacity to adapt to unusual requirements,
Significant place in advanced technology sectors – they are utilized in HDD drives, brushless drives, diagnostic systems, also complex engineering applications.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Limitations

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we recommend using special steel holders. Such a solution protects the magnet and simultaneously improves its durability.
Neodymium magnets decrease their force under the influence of heating. As soon as 80°C is exceeded, many of them start losing their force. Therefore, we recommend our special magnets marked [AH], which maintain stability even at temperatures up to 230°C
They oxidize in a humid environment - during use outdoors we suggest using waterproof magnets e.g. in rubber, plastic
Due to limitations in creating threads and complicated shapes in magnets, we propose using cover - magnetic mount.
Health risk related to microscopic parts of magnets are risky, if swallowed, which gains importance in the aspect of protecting the youngest. It is also worth noting that small elements of these devices are able to disrupt the diagnostic process medical when they are in the body.
With budget limitations the cost of neodymium magnets can be a barrier,

Holding force characteristics

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity represents the maximum value, obtained under optimal environment, specifically:

using a sheet made of mild steel, serving as a magnetic yoke
with a cross-section minimum 10 mm
characterized by lack of roughness
without the slightest clearance between the magnet and steel
under axial force direction (90-degree angle)
in stable room temperature

Lifting capacity in real conditions – factors

Holding efficiency is influenced by working environment parameters, such as (from most important):

Clearance – existence of any layer (paint, dirt, air) interrupts the magnetic circuit, which lowers capacity rapidly (even by 50% at 0.5 mm).
Loading method – declared lifting capacity refers to detachment vertically. When applying parallel force, the magnet exhibits significantly lower power (typically approx. 20-30% of nominal force).
Base massiveness – too thin steel does not accept the full field, causing part of the flux to be lost to the other side.
Metal type – different alloys attracts identically. High carbon content weaken the interaction with the magnet.
Smoothness – ideal contact is possible only on polished steel. Any scratches and bumps create air cushions, weakening the magnet.
Thermal environment – temperature increase results in weakening of induction. Check the thermal limit for a given model.

Lifting capacity testing was performed on plates with a smooth surface of optimal thickness, under a perpendicular pulling force, however under parallel forces the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate decreases the lifting capacity.

Safe handling of NdFeB magnets

Crushing force

Risk of injury: The pulling power is so immense that it can result in blood blisters, pinching, and even bone fractures. Use thick gloves.

Safe distance

Do not bring magnets close to a purse, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

Caution required

Use magnets with awareness. Their immense force can shock even experienced users. Plan your moves and do not underestimate their force.

Life threat

Medical warning: Neodymium magnets can deactivate heart devices and defibrillators. Stay away if you have medical devices.

Skin irritation risks

Medical facts indicate that the nickel plating (standard magnet coating) is a strong allergen. If your skin reacts to metals, refrain from touching magnets with bare hands and choose versions in plastic housing.

Do not drill into magnets

Fire hazard: Rare earth powder is highly flammable. Avoid machining magnets in home conditions as this may cause fire.

Fragile material

Despite metallic appearance, neodymium is delicate and not impact-resistant. Avoid impacts, as the magnet may crumble into sharp, dangerous pieces.

Operating temperature

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

Impact on smartphones

GPS units and smartphones are extremely susceptible to magnetism. Direct contact with a strong magnet can decalibrate the internal compass in your phone.

Choking Hazard

These products are not intended for children. Swallowing a few magnets may result in them connecting inside the digestive tract, which poses a severe health hazard and necessitates urgent medical intervention.
