Magnet fishing
Need advice? Frequently asked questions from customers.
Magnet fishing is a big hit, especially here in the Czech Republic, where it is becoming increasingly popular. We offer very strong fishing magnets, or magnets for treasure hunters. Our weakest magnet has a pull force of 94 kg, while our strongest has an incredible pull force of 1,100 kg! With this magnet, you can pull out some real catches. If you want to pull objects such as bicycles, safes, weapons, and other heavy items out of the water, we recommend stronger magnets with a pull force of 500 kg and above. We also offer accessories such as very strong ropes, which you will need. Are you also interested in what's in your local reservoir? Nothing could be easier than buying a decent magnet and casting it!

1Choose the pull force from what you expect to find
The range runs from 94 kg to 530 kg in single-sided magnets and from 2 x 310 kg up to 2 x 1,100 kg in double-sided ones. For coins, keys, tools and small scrap, the lower end is plenty.
For bicycles, safes and genuinely heavy objects, take 500 kg and above. Below that you will find the object and then fail to move it, which is the most frustrating outcome there is.
2Understand single-sided versus double-sided
A single-sided magnet pulls only through its flat face. It is the right choice for vertical searching: dropping straight down from a bridge or a pier onto the bottom.
A double-sided magnet works through both faces, which suits dragging along the bottom or searching a bank, because the catch can come from either side. The stated figure, for example 2 x 500 kg, is the force per face, not the two added together.
3Match the rope to the magnet, not to the water
The rope is the part that decides what you actually recover. We stock ropes in 15 m and 30 m lengths, rated at 340 kg and 560 kg. A rope rated well below the magnet is the weak link, and it fails at the worst possible moment, with the catch halfway up.
Take 15 m for bridges, piers and small ponds, and 30 m for rivers, canals and open water where you will also want to cast some distance. Buy a spare: ropes get cut on scrap metal and rough stonework.
4Read the stated force for what it is
The pull force is measured in direct contact with a thick, flat, clean steel plate, pulled straight off. Underwater you are dealing with rusted, curved, muddy objects lying at an angle, so the real recovery force is a fraction of the catalogue figure.
Direction matters as much as force: a magnet resists a straight pull far better than a sideways drag, so lift vertically rather than hauling the object along the bottom.
5Check the rules before the first cast
Magnet fishing is not permitted everywhere and the rules differ by country and by site. In most places you need the consent of the owner or administrator of the water, and protected areas, harbours and heritage sites usually have their own restrictions.
If you pull out ammunition, a weapon, or anything that looks like ordnance, do not handle it and do not take it home. Put it down, move away and call the police. The same goes for anything that could be evidence.
6Handle the magnet as the hazard it is
- Wear sturdy gloves: recovered scrap is sharp and rusty, and rope burns are the most common injury.
- Never wrap the rope around your hand or wrist when hauling.
- Keep fingers out from between the magnet and the catch. At these forces a magnet closes faster than you can react.
- Keep the magnet well away from phones, cards, hard drives and pacemakers, and out of reach of children.
Tip: Before you buy the strongest magnet in the range, check how you will get it off the catch. A 1,100 kg magnet stuck to a steel beam cannot be pulled free by hand; it has to be slid sideways off the edge. Many people are better served by a 290 to 530 kg magnet they can actually work with all afternoon.

Frequently asked questions about magnet fishing
The range starts at 94 kg and runs to 530 kg single-sided and 2 x 1,100 kg double-sided. For coins, keys, tools and small scrap, the lower end is enough. For bicycles, safes and heavy objects, take 500 kg and above, because a magnet that finds an object it cannot move is the most common disappointment for beginners.
A single-sided magnet pulls through its flat face only and suits vertical searching straight down from a bridge or a pier. A double-sided magnet works through both faces and suits dragging along the bottom or searching from a bank. A figure such as 2 x 500 kg is the force per face, not the total.
Ropes are stocked in 15 m and 30 m lengths, rated at 340 kg and 560 kg. Take 15 m for bridges, piers and small ponds and 30 m for rivers, canals and open water. Choose the load rating with the magnet in mind, since the rope is the weak link in the system, and keep a spare because ropes get cut on scrap metal and stonework.
No. That figure is measured in direct contact with a thick, flat, clean steel plate, pulled straight off. Real finds are rusted, curved, muddy and lying at an angle, so the usable force is a fraction of the catalogue value. Lift vertically rather than dragging sideways, because a magnet resists a straight pull far better than a shear load.
No, and the rules differ by country and by site. In most places you need the consent of the owner or administrator of the water, and protected areas, harbours and heritage sites have their own restrictions, so check before you go. If you recover ammunition, a weapon or anything resembling ordnance, do not handle it or take it away: put it down, move back and call the police.
Wear sturdy gloves, never wrap the rope around your hand or wrist, and keep fingers out from between the magnet and the catch, because at these forces it closes faster than you can react. Keep the magnet away from phones, payment cards, hard drives and pacemakers, and out of reach of children. Plan how you will separate it from a large catch before you buy the strongest one.
Magnet fishing is the one hobby where the equipment is genuinely industrial, so it is worth buying it from people who build industrial magnets. Our fishing magnets run from 94 kg up to 2 x 1,100 kg of pull force, with single-sided versions for searching straight down and double-sided versions for dragging, plus ropes in 15 m and 30 m lengths rated at 340 and 560 kg. We state the pull force and the conditions it applies to for every magnet, and we will tell you honestly when a smaller one is the better buy.
