BIG JOHN FISHING MAGNET – 200KG SINGLE-SIDED

The 200kg Big John Fishing Magnet is a single-sided Neodymium magnet also commonly referred to as a “pot magnet”.

This Big John Fishing Magnet measures a wide 75mm in diameter for a larger surface area to catch underwater metal objects. It is 18mm in thickness making it an excellent choice for magnet fishing. At only 1kg it is light enough to carry in your backpack and take along hiking, boating or wherever your adventures take you. Despite its compact size it still offers serious lifting strength of 200kg, perfect for magnet fishing.

It comes supplied with an M10 Eye Bolt made of 304-grade Stainless Steel which is mounted on the horizontal/top side of the fishing magnet where there are pre-existing thread receivers.

Our fishing magnets are coated in a thin NiCuNi protective layer preventing damage to the internal magnets and making them suitable for magnet fishing.

PRECAUTIONS

The fishing magnet’s magnetic ends may show signs of wear due to strong forces and heavy impacts received. Throwing the fishing magnet into the water, they tend to hit rocks, and hidden objects, and when latching on to metal, they do so with considerable force. Try to avoid areas with rocks as the fishing magnets can crack on impact with such objects.

Removing the magnets from the metal object also applies wear to the magnet as this is typically done by sliding and scraping the metal object off the magnet’s surface.

When used in water, especially seawater, you will see rust appear, where the protective coating has been pierced or worn through.

This kind of wear is normal and is expected, even after only a few uses, due to the above factors.

Keep magnets away from persons with pacemakers, electronics, and sensitive instruments such as avionics to avoid possible permanent damage or disruption in their use.

The magnets exert a tremendous crushing force if fingers and body parts are trapped between the magnet and metal objects. Keep magnets away from children.

AFTERCARE TIPS

  • Rinse the magnet off in freshwater after each use
  • Apply an anti-rust agent such as Q20 after each use
  • Leave a coating of an anti-rust agent on the magnet while in storage and between use
  • Avoid throwing or dropping the magnet into the water where you know there are rocks and similar hard objects
  • Apply Loctite or similar nut locking agents to the thread of the eyebolt to prevent unthreading
  • After each throw check the eyebolt to ensure it is still tight and inspect the rope and knot for wear

INTERESTING FISHING MAGNET INFORMATION

The magnet Vertical Pull Strength Rating of 200kg is measured in laboratory conditions using a solid steel plate which is 10mm thick with the magnet placed in the centre of the plate and positioned horizontally on top. An instrument that measures force pulls the magnet steadily upwards at a constant pulling speed of 80mm per minute. The force in kilograms, at the point just prior to the magnet breaking away from the steel plate, is recorded and constitutes the magnet’s vertical pull strength rating.
