Product Description
Heavy-Duty 1350 LB Neodymium Fishing Magnet (5.4" Sintered NdFeB Salvage Magnet)
This assembly produces an exceptionally strong magnetic field capable of crushing fingers and causing severe bodily injury. Sintered neodymium magnets attract to steel and to each other with sudden, unstoppable velocity from several inches away.
- Pinch & Fracture Hazard: Never place your fingers, hands, or feet between the magnet face and any metal object or another magnet. Wear heavy-duty leather work gloves during all handling.
- Medical Devices & Pacemakers: Keep this magnet at least 12 to 18 inches away from cardiac pacemakers, ICDs, insulin pumps, and other medical implants. Static magnetic fields can alter device operation.
- Keep Away from Children: This is an industrial-strength salvage tool, NOT a toy. Keep strictly out of reach of children and minors.
The CMS Magnetics 1350 LB Heavy Duty Fishing Magnet is an industrial-grade rare-earth recovery magnet engineered specifically for deep-water river salvage, lake treasure hunting, and heavy magnetic retrieval. Measuring 5.4 inches (136 mm) in diameter, this high-energy sintered neodymium (NdFeB) core is encased inside a precision-machined, heavy-gauge steel cup that concentrates all magnetic flux directly onto a single forward contact plane.
Engineering Specifications & Dimensions
- Direct Pull Force Capacity: 1,350 lbs (612 kg) under ideal laboratory conditions on solid, clean 1" thick carbon steel plate.
- Outer Cup Diameter: 5.4 Inches (136 mm).
- Magnetic Core: High-Grade Sintered Rare-Earth Neodymium-Iron-Boron (NdFeB).
- Surface Plating: Triple-layer Ni-Cu-Ni (Nickel-Copper-Nickel) protective electroplating for corrosion resistance in fresh and brackish water.
- Hardware Attachment: Heavy-duty forged steel lifting eyebolt with nylon locking ring to prevent vibration loosening during retrieval.
Protects brittle sintered NdFeB edges against underwater rock strikes while focusing 100% of magnetic field lines toward target iron relics.
Engineered to break heavy submerged targets out of dense river mud, silt, and clay—ideal for bikes, safes, engine blocks, and tools.
Threaded directly into the solid steel cup casing, providing balanced retrieval whether casting from bridges, piers, or watercraft.
Safe Handling, Storage & Field Rigging Guide
- How to Detach from Flat Steel (Shear Sliding): If the magnet attaches flush to a thick steel plate (bridge beam, car panel, or dock rail), you will not be able to pull it straight off by hand. Slide the magnet sideways to the edge of the metal surface rather than attempting to pry it straight up.
- Eyebolt Threadlocking: Always apply blue or red threadlocker (Loctite) to the M12 eyebolt threads and hand-tighten firmly with a screwdriver shaft through the eye. Water currents and continuous bottom bouncing can back out an untreated thread.
- Rope Breaking Strength: Pair this 1,350 lb magnet with a non-stretch static braided nylon rope rated for at least 1,500 to 2,000 lbs breaking strength. If your magnet snags on a submerged bridge pile or car chassis, standard consumer ropes will snap under extraction tension.
- Electronic & Vehicle Precautions: Keep this magnet at least 2 to 3 feet away from vehicle computers, smartphones, key fobs, magnetic cards, laptop hard drives, and navigation compasses.
- Post-Water Maintenance: After each outing, rinse the magnet with fresh tap water to remove corrosive salts, river mud, and metallic grit. Dry thoroughly with a towel and store inside a padded non-ferrous plastic container with wooden spacers.
