The ultimate guide to magnet fishing with neodymium magnets (2023)


Welcome to this ultimate guide to magnet fishing! This guide will give you the information you need to know everything you need to know about this fun hobby, how to get started, where are the best places to magnetize fish and other useful information.

What is magnet fishing?

Similar to metal detection, which involves finding objects on land using a metal detector, magnet fishing involves finding metal objects in water with strong magnets. Have you ever imagined what could be at the bottom of a lake near where you live? There have been interesting finds by people curious enough to tie a magnet to the end of a rope to answer this question - many of them were very surprised by what they found.

Magnet fishing is indeed an interesting and inexpensive outdoor hobby that anyone can pursue and it gives the outdoor enthusiast the opportunity to interact with their surroundings in unique ways. Imagine experiencing the thrill of chasing what you'll find next, the excitement of pulling a metal treasure out of the water, and being able to easily and quickly see what's "underneath." of the surface” when you think you come across an interesting waterhole can hold something special.

Setting Up Magnet Fishing - Getting Started

For yourmagnetic fishing gearand set up you need a few things. Similar to fish fishing, where you have a hook, line, and plumb line, magnet fishing requires a strong magnet for the hook and plumb line, and a rope for the line that attaches to the magnet. Where you magnetize fish is important to increase your chances of finding metal, and a large element of patience and curiosity is also required. Unlike fish fishing, magnet fishing gives faster results in catching anything; You'll quickly learn if there's metal lurking beneath the surface, and you can catch up with it if you can feel the magnet sticking strongly to something.

For magnet fishing you need a very strong magnet. It's best to take the strongest magnet you can carry and tie it securely to a rope.Remember that the pull of the magnet is greatest when the metal object is completely flat. However, flat contact would be difficult to achieve in magnet fishing, as objects that have been lying at the bottom of a lake for a long time tend to accumulate dirt (soil, vegetation, rust, algae, etc.) and the metal object itself must not be flat - that's why it is advisable to use a much stronger magnet to compensate for these irregularities. Also keep in mind that the larger finds will need a stronger magnet to be pulled from their long standing resting place, through and out of the water.

Best magnets for magnet fishing

Thebest magnet for magnet fishingis a neodymium magnet because its relatively compact size can have tremendous pulling power.Neodymium magnets are rare earth magnets and are considered to be one of the strongest magnets available. As a precaution, please be very careful when handling these magnets as they are very strong and can cause injury and damage electronics. Never try to put two of these magnets together as the force may break them.

Below is a neodymium N52 magnet that weighs less than 2 pounds but has a pull force of 500 pounds.This has a countersunk screw attached to it, making it easy to attach an eye bolt to tie the leash securely. Be sure to use Loctite to keep the eyebolt from loosening.

Best rope for magnet fishing

In addition to a strong magnet, you need a good rope as a leash. We recommend getting at least 50 feet of rope, which would be long enough for shallow water and fishing in most locations. If you are sure that the place you want to fish is very deep, or you want to cast your line far from the water's edge, you can use a 100ft line. When fishing from bridges, be sure to use a 100ft line.

We recommend using a good quality nylon paracord for its strength, durability, elasticity, high resistance to abrasion and its ability to hold a knot very well; All of this is important given the conditions you may be fishing in where the water could be murky and the magnet getting stuck on something that would require a strong tug on the line to release. Its elasticity makes it slack, and because paracord rope is light and thin, the pull feedback you get when you feel the rope is much more sensitive; You will know when the magnet has caught something.

Note that not all paracords are created equal as there are different degrees of strength depending on how they are made.Below is a nylon paracord, and it's 50 feet long.This is 4mm, Type 3 and has 7 braided core yarns allowing it to have a minimum strength of 550lbs making it a perfect complement to the 500lbs magnet.

Magnetic fishing accessories and other equipment

As with any outdoor activity, make sure you bring appropriate gear to get the most out of the experience. Bring at least a bucket to carry your finds, a brush to brush away debris, and wear sturdy gloves to avoid injury when pulling the rope and handling sharp and rusty metal. Bring a small plastic container to store small items such as fishhooks and lures, nails and other metal parts. You can add a grappling hook to your gear, which comes in handy when recovering heavy objects.

Take care of yourself by wearing a hat, sunglasses and sunscreen. Wearing insect repellent is very important as mosquitoes breed and inhabit water areas and their surroundings. You may wear waterproof waders and rubber boots depending on the area, such as swamps and wetlands.

Strong knots for magnet fishing

The best knot for magnet fishing is one that is self-tightening and provides a secure hold on the magnet. Also, the knot must be one that can bear heavy weight. If you are a fish angler and have a favorite knot then try using it for your magnet. For beginners, we recommend the proven Palomar as yoursmagnetic fishing knotas it is very easy to tie and is considered by many to be one of the strongest knots.

The best places to magnetize fish

Almost all places have bodies of water such as lakes, rivers, swamps, ponds, streams, dams, canals and sewers. You will definitely find metal in urban areas and in places that are frequently visited, walked along and reachable on foot. Also, in rural and remote areas, try fishing in less visited areas which can produce interesting metal finds that have long been undisturbed. If you happen to spot an old well or drain, then by all means drop your magnet there.

Cities steeped in history are great places to attract fish. You can imagine the kind of metal treasures long discarded from times of industrial development, the gold rush, the nearby disused munitions factories and mines, and the areas that were once war fronts. Take the time to visit old towns and drop your magnet to see if you can find a piece of their history. Who knows, your finds might even contribute to the local museum.

Finds while magnet fishing - what people have found

People have found all sorts of objects while magnet fishing. If you're one of the lucky ones (and there are many lucky magnet fishermen out there) then you might have found everything from bullets, duds, swords, handguns to machine guns. Aside from the weapons, you'll find street signs, shovels, tools, nails, fishing hooks, ball bearings, anchors, propellers, and other unique objects. To improve your chances, go fishing in places where you are most likely to find metal treasure. Sights, places with rich history and places where battles once took place. Fishing at WW2 sites yields items used during that time. Below is part of theBasingstoke Canal UK wo aA six-year-old girl and her parents threw up 6,000 bullets. This area ofCanal is nearbyPirbright Army Training Center.

Is magnet fishing legal?

When it comes toMagnet Fishing Laws, rules vary by country and state laws and it is best to check with local government agency if unsure. Different people will have different views on whether magnet fishing is legal or illegal. However, you can choose to look at magnet fishing as an eco-friendly activity that helps clean the waterways of junk.

Magnet fishing itself is not specifically illegal in most places, but littering and unrestricted dumping is. When discovering new places, respect private property and ensure that all rubbish is properly disposed of and never throw what you find back into the water. If you are carrying firearms and explosive devices, be sure to check with local authorities as possession without a permit is illegal and poses a dangerous threat to people's safety when the guns are still live, e.g. B. an unexploded bomb. These items must be reported to the police so that they can be safely detonated.

Magnet fishing safety

The most important factor is your safety and that of others. Be considerate and always use common sense. Do not magnet fish where there are signs saying fishing is prohibited.

If you're fishing from a pier or bridge, make sure the magnet doesn't get close to metal supports or poles as it would stick to them.

Always be aware of your surroundings and be careful where you throw your magnet and line as you don't want the magnet catching on a moving watercraft or propeller.

So be a safe and environmentally conscious magnet fisherman and you can be proud that you have in some way contributed to making a positive impact on the environment while enjoying this hobby and the great outdoors.


Magnet fishing is suitable for curious, nature-loving and patient people. You may be an explorer, adventurer and big game hunter of sorts, which is your main interest, but the simplicity of simply dropping a magnet and rolling it up after feeling the "magnetic clink" creates the excitement and anticipation of what is brought becomes the surface. That excitement never gets old as you explore new fishing spots or quickly stop to drop your magnet when you come across an interesting spot. You can devote as little or as much time to this hobby as you like. Remember, you're just a toss away from finding your next metal treasure.


Magnet fishing is indeed a fun hobby that anyone can enjoy. It's easy to get started and easy to set up,inexpensive,and offers hours of outdoor enjoyment. You never get tired of exploring different locations to magnetize fish and you can find interesting artifacts from history depending on the locations you choose. Finally, make sure safety always comes first and try to bring someone with you to share the experience with.
