Magnet Fishing
Pulling history from the depths
About Magnet Fishing
Magnet fishing uses neodymium magnets — rare-earth magnets capable of 500 to 1,200+ lbs of pull force — to recover ferrous metal objects from rivers, canals, lakes, and harbors. The magnets attach to a rope, get lowered or thrown into the water, and dragged along the bottom. What comes up ranges from rusted bolts and bike frames to Civil War-era hardware, old safes, and the occasional firearm.
Most serious setups use either a single-sided magnet (strongest pull in one direction, better for vertical drops off bridges) or a double-sided magnet (pulls from both faces, better for dragging). The choice depends on how you fish — vertical drops from a bridge call for a different setup than a horizontal drag through a shallow canal.
The most productive locations are urban waterways with long human histories: old ferry landings, canal lock sites, mill ponds, historic bridge crossings, and harbor edges where boats were moored for generations. These are places where metal objects entered the water continuously over decades — and where almost nobody has fished with a magnet before.
Equipment Guide — What pull force you actually need — most productive setups fall between 500 and 1,200+ lbs — and which rope, gloves, and grappling hook configurations hold up in current.
Best Locations — Old ferry crossings, canal locks, mill bridges, and urban waterway choke points — places where people and goods moved for decades and things inevitably ended up in the water.
Safety & Laws — Magnet fishing is restricted or outright banned in some waterways and jurisdictions — know before you throw, and know what to do if you pull up something dangerous.
Clean & Restore — Most of what comes up is rusted iron junk; occasionally something is worth cleaning — here’s how to tell the difference and handle both without destroying the find.
Forum Discussion — Share finds, get location tips, and ask about anything unusual you pulled up.
Check local laws before you go — magnet fishing is restricted or prohibited on certain waterways, including some canals and navigable rivers, and the rules vary by state and municipality.
Use rope rated well above your magnet's pull force, and learn proper knots — a figure-8 or double fisherman's knot is far more reliable than a basic overhand under load.
Prioritize historically significant locations: bridges at old ferry crossings, mill ponds, canal lock sites, and harbors with pre-1900 activity tend to produce better finds than random urban waterways.
Wear heavy-duty gloves on every session — cuts from rusted metal edges carry a real infection risk, and the magnet itself can pinch badly if a heavy find swings into your hand.
Have a plan for scrap disposal before you start — most of what you pull up is ferrous junk, and some municipalities require you to haul it to a designated metal recycling facility rather than leave it at a standard dump.
Keep strong magnets away from phones, credit cards, and anything with a magnetic strip or hard drive — the field is strong enough to cause real damage at close range.
