Double Sided Fishing Magnet Supplier

1. Overall Form and Construction

• Shape & Dimensions:

  • The body is a thick, circular cylinder (puck-style) approximately 2–3″ thick (exact dimensions vary by manufacturer).

  • Both faces (top and bottom) are flat, allowing equal magnetic attraction on each side.

• Material:

  • Encased in a nickel-plated steel shell. The nickel finish gives it a smooth, corrosion-resistant outer layer—ideal for repeated submersion in water.

  • Inside, there is a high-grade neodymium magnet (NdFeB) block or array, providing very strong pull force.

2. Double‐Eye Bolt Design

• Two Eye Bolts (One on Each Face):

  • Each face of the magnet has a threaded boss and a large, welded eye bolt screwed into it.

  • This allows you to attach a rope, carabiner, swivel, or winch from either side—and you can flip the magnet over without losing functionality.

• Eyebolt Size & Rating:

  • The eyebolt itself is usually forged stainless steel (or zinc-plated steel), rated well above the magnet’s pull capacity so that the weakest link is the magnet’s rated pull, not the bolt.

  • Typical threads are M12 or ½″-13 (imperial), depending on manufacturing standard.

3. Pull Rating (“2600 lb”)

• “2600 lb” Pull Force:

  • Indicates an ideal maximum pull force of around 2,600 pounds (≈1,180 kg) when the magnet is in perfect contact with a thick, clean, flat steel surface under laboratory conditions.

  • In real-world use (mud, rust, paint, uneven surfaces), actual pull strength is often reduced—sometimes by 20–50%.

• Use Case:

  • This rating makes it suitable for retrieving large anchors, car parts, tools, or heavy scrap out of a lake or river.

  • It’s not meant to hold a 2,600 lb load safely in mid-air; it simply means that, on a perfect surface, the breakaway force is approximately that much.

4. Typical Uses

1. Magnet Fishing

   • Tie a sturdy rope to one eyebolt, toss the other face down into water, “fish” for buried or submerged ferrous objects (bicycles, nails, car parts, etc.).

   • Once you feel a “jerk” or see the rope sliding, gently pull upward to retrieve whatever’s stuck to the magnet.

2. Salvage & Retrieval

   • Use in ponds, canals, wells, or drainage ditches to recover tools or metallic debris.

   • Often used by municipalities or private contractors to clean up construction sites or waterways.

3. Industrial Lifting Aid (Light-Duty)

   • When mounted beneath a steel plate or beam (top side of the magnet), it can temporarily hold up small items (hooks, chains, light signs). The second eyebolt can then hold that load.

   • Note: Always factor in a safety margin; never exceed about 20–30% of the rated pull force for overhead lifting.

5. Practical Considerations

• Surface Condition Matters:

  • For maximum hold, both contact faces of the magnet and the steel object should be clean, flat, and free of paint/rust/scale. Any gap (even a thin layer of mud) drastically reduces holding power.

• Use a Safety Rope/Clamp:

  • It’s common to attach a safety line to the secondary eyebolt. If the primary rope or carabiner slips, the magnet won’t be lost.

• Corrosion & Maintenance:

  • After use in saltwater, rinse thoroughly with freshwater and dry completely to prevent any long-term corrosion (the nickel plating helps, but salt can still find crevices).

• Alignment:

  • Because it’s double-sided, make sure to lay it flat against the target metal. If you approach at an angle, the attraction will be weaker.

6. How to Use (Step‐by‐Step)

1. Preparation

   • Inspect both magnet faces. Wipe away any debris or rust.

   • Securely screw in (and torque) the eyebolt(s) if they’re removable.

   • Attach a strong rope or braided line (minimum 3/8″ dynamic rope recommended) to one of the eyebolts.

2. Lowering

   • Carefully lower the magnet into water (or over the dumping area). Keep the rope taut so you can feel any vibrations or pull as it contacts metal.

3. Locating Objects

   • Slowly drag the magnet across the bottom surface, listening/feeling for any change in tension.

   • When it “locks on,” pause and gently pull to see if it has latched onto something substantial.

4. Retrieval

   • Slowly pull the magnet straight up (avoid jerking). If the target object is heavy, angle yourself so you can brace and let gravity help free it from the mud or silt.

   • Once retrieved, detach the object from the magnet (wear gloves—sharp metal edges are common).

7. Safety Tips

• Wear Protective Gear:

  • Gloves (magnet‐grabbed scrap can have jagged edges), closed-toe shoes, eye protection.

• Mind Pinch Points:

  • Two powerful magnets snapped together can trap fingers in between. Always keep your hands clear of the mating surfaces.

• Be Aware of Surroundings:

  • If fishing from a boat or dock, ensure balanced footing. A sudden “snap” of a heavy object can pull you toward the water.

• Do Not Use Near Electronic Devices:

  • Strong neodymium magnets can damage hard drives, credit cards, pacemakers, and other sensitive electronics.

• Avoid Contact with Explosives:

  • If you’re searching in old docks or piers, be mindful of potential unexploded munitions—especially in historically active waterways.
