Magnet Fishing: Searching Unexplored Waters
Imagine all the things that have been dropped into bodies of water over the years. Watches, jewelry, phones, guns, and pretty much anything else you can think of are lost and seemingly gone forever.That’s where magnet fishing comes in (and it has nothing to do with fish).
What is Magnet Fishing?
Magnet fishing involves dropping a strong Neodymium magnet attached to a rope into a river, creek, lake or other body of water. The magnet can find and recover things like jewelry, weapons, bicycles, and m0re.
Neodymium magnets are extremely strong. Neodymium is a rare-earth magnet, meaning it’s made out of rare-earth elements. Only 17 rare-earth elements exist. The “rare” part doesn’t mean they’re hard to find, but that they are not found in high concentrations, and are challenging to find in their pure form.
Rare-earth elements are part of what make our modern world tick. They’re in nearly every piece of technology: cell phones, catalytic converters, MRI scanners, microwave ovens, computers, and more.
According to University College Professor Andrea Sella, rare earth magnets are 10 times as powerful as a normal iron magnet, and some can hold 1,000 times their own weight.
It’s an exciting experience to find something that has rested at the bottom of a river for a long time, and if it’s made of ferrous material, a Neodymium magnet will find it.
Choose Your Magnet Fishing Equipment
To get started, select a magnet designed specifically for magnet fishing, as well as a rope. The magnets are rated by pounds of lift or pulling force. The pull force is the highest possible holding power, and is the force required to pry a magnet away from a flat steel surface.
Temperature, environmental conditions and the material of the item you’re pulling out of the water all affect the magnet’s performance. If you have a magnet with a pull force of 880 lbs., for example, that doesn’t mean that you can pull an item that weighs that much out from the bottom of a river. The pull weight is determined at a lab under ideal conditions, and those conditions don’t exist out in nature.
Most magnet fishing enthusiasts recommend a magnet with a pull weight of between 300-500 pounds for beginners. There are also models designed specifically for younger magnet fishers.
A basic figure-eight follow through knot is the best knot to use as you loop your rope through the eyebolt that comes on magnets designed for magnet fishing. A palomar knot will work as well.
It’s best to use a nylon paracord rope that’s at least 50 feet long. Paracords hold knots very well and are slightly elastic. If you plan to fish from bridges, or if you know the place you want to fish is very deep, use a 100 foot rope.
Most magnets you purchase will also come with a threadlocker that will prevent the eyebolt from unscrewing.
Invest in a pair of gloves, since you’ll be tugging on a rope and may end up bringing up items that are rusty and possibly sharp. Other protective gear, like safety glasses, isn’t a bad idea either, since you never know what you’ll find. Bring along a bucket for your finds and a trash bag for the junk. A great place to start is to purchase a magnet fishing bundle that has all of your needs, like the Brute Magnetics Brute Box 1200.
How to Magnet Fish
Some of the best places to go magnet fishing include places with a lot of foot traffic, like fishing piers, docks, underneath bridges, near historic sites, or canals.
Fishing piers are great locations for magnet fishing, too.
Check up on local laws before you start magnet fishing because it’s illegal in some rivers in Western Europe, and you’ll need a permit in other areas. This is because rivers in places like England are littered with weapons from World War II, including undetonated explosives, like grenades.
Once you’ve selected your location, set up all your gear.
There are different methods for magnet fishing. The up and down method involves throwing the magnet into the water and not dragging it. Just drop it in and lift it up.
The throw and pull method involves throwing the magnet out as far as you can, then pulling it back in. You’ll most likely snag objects along the way, but the downside is that your magnet can get stuck.
To use the throw, pull and walk method, throw the magnet in, then take a walk along the river or creek as you drag the magnet along.
Other hobbyists prefer the “hop” method. That avoids dragging the magnet and instead drops the magnet in, lifts it up, and sets it back down just a few inches away. That prevents the magnet from getting lodged somewhere.
One of the benefits of magnet fishing is that it cleans up the river by pulling out a hefty amount of junk. Make sure to clean up after yourself once you’re done for the day. Bring home your finds and clean them up, but don’t throw the junk back into the river. Dispose of it in a trashcan or at a convenience center.
Note: Pacemakers and electronics can be affected by strong magnetics. If you wear a pacemaker, you shouldn’t use strong magnets.
