Questions and answers about magnet fishing
Which magnets can I use for magnet fishing?
- With its adhesive force of 45 kg, the treasure hunter magnet incl. nylon rope is a good entry-level set.
- Our largest ring magnet with 120 kg adhesive force can be easily attached to a nylon rope.
- Directly tied to a rope, eyelet magnets can be used for fishing with magnets.
- You can easily screw a suitable threaded eyelet into pot magnets with a screw socket and pot magnets with an internal thread and attach a nylon rope.
- Connected with a screw: Pot magnets with counterbore screw-on or Pot magnets with cylindrical borehole screw-on
- Threaded or fastened with a nut: Pot magnets with threaded stud
A pot magnet is a magnet that has been embedded in a steel pot. The steel pot increases the adhesive force of the magnet when making direct contact with a thick iron surface. In contrast, neodymium magnets without pots have a stronger adhesive force at a distance. You can find more information about pot magnets in our FAQ pot magnet characteristics.

How can I make my own retrieving magnet?
- A countersunk pot magnet, here we used the CSN-60
- A countersunk screw with hexagon socket, M8 thread, total length 30 mm
- A ring nut, M8 internal thread
First, push the screw through the hole in the pot magnet. Now you only need to thread the ring nut onto the screw. It is recommended to use a thread-locking fluid such as Loctite, to prevent an accidental loosening of the screw during magnet fishing.
Those who find that the adhesive force of a single magnet is not powerful enough for magnet fishing can, with a little skill, build a “slightly” bigger retrieval magnet. In the customer project Magnet fishing in XL we gathered information on the necessary materials and how to proceed. And if you feel this is a little too ambitious, you can instead find instructions for making a magnetic fishing rod with our strongest ring magnet R-60-06-30-N.
What is the best way of attaching a rope to the fishing magnet?There are many good knots for tying a rope to the fishing magnet. The important thing is, that the knot holds firm. After all, it would be a pity, if your magnet takes a dive into the water without the rope.
Tips for fishing with magnets
Legal situationIn most European countries, it is not conclusively clarified whether magnet fishing is permitted or not. Furthermore, within Germany, the state laws of the respective states have to be considered. So, before you set out with your magnetic fishing rod, always make sure to first learn about the legal situation in your region. If in doubt, check with the local police.
Also, keep in mind that magnet fishing is not permitted in all waters. For example, for a privately owned body of water, you will need permission from the owner. In addition, you will have to comply with all measures for the preservation of nature and historical sites.
Required adhesive forcePlease keep in mind: The adhesive force noted for the magnets is the maximum force under ideal conditions. You will need a very strong magnet, if the item to be retrieved is lacquered or painted, has a rough or uneven surface or is not made from pure iron (see specific FAQ about adhesive force). In addition, there is the water pressure that has to be overcome during retrieval. It is much higher than air pressure. If in doubt, always use magnets with an adhesive force of at least 30 kg for magnet fishing.
StorageMagnets used for magnet fishing must be stored safely. With such a strong adhesive force it is not uncommon for these magnets to inadvertently attach to a ferromagnetic surface while being transported in a car or while being improperly stored. That is why these magnets need to be shielded when not in use. The medium plastic case filled with cubed foam, for example, is suitable for this purpose.
CorrosionIf you repeatedly expose a neodymium magnet to water and without protection, it will eventually start to rust. You should therefore thoroughly dry the magnet after each use. You can also treat the magnet with a waterproof lacquer to provide some protection.
Chipping, breaksCollisions between strong magnets and coarse metal objects will inevitably lead to damage of the magnet coating, to a point where it could even chip off. Magnets can also break during heavy collisions because they are very brittle. Unfortunately, in combination with the corrosion issues, you can expect having to replace the fishing magnets every now and then.
Safety distancesThe magnetic strips of credit and EC cards will be quickly demagnetised by magnets of this size and will not work afterwards. Therefore, when fishing with magnets, please keep your wallet away from these magnets. People with pacemakers and/or hearing aids should be especially careful as well. You can find further information on this topic in our FAQ about safety distances.
Additional safety information
- Be extremely cautious in areas where unexploded bombs or other munitions may be found! Should you come across explosives while magnet fishing, do not touch them and call the police.
- If you really do find a treasure, you are usually not allowed to keep it - follow the legal regulations!
- Magnets used for magnet fishing do not belong in children’s hands. Store your retrieval magnet out of reach for children.
- The stronger the adhesive force of a magnet, the higher the risk for injury. Always wear safety gloves when magnet fishing. Cut-resistant ones are best.
- When casting the retrieval magnet, always make sure that it is safe to do so for you and your surroundings. People, animals or boats should not be in close proximity to you and should remain well outside the trajectory route of the magnet.
