BIG JOHN FISHING MAGNET – 400kg
The 400kg Big John Fishing Magnet is a popular choice for Magnet Fishing due to it’s size, yet it is super strong. It is a double sided Neodymium magnet, consisting of 2 magnets on either side, which gives you the benefit of twice the surface area to snatch objects, effectively doubling your chances to attract something great.
This fishing magnet measures 107mm in diameter and 35mm in thickness making it an excellent choice for magnet fishing. It boasts a hefty lifting strength of 400kg on both sides, guaranteed to give you the best opportunity for a rewarding catch.
It comes supplied with a M12 Eye Bolt made of 304 grade Stainless Steel which can be mounted on either the top or side of the fishing magnet where there are pre-existing thread receivers. We recommend mounting it on the side of the fishing magnet as this doubles the magnets surface area, effectively doubling your odds of catching something.
Our fishing magnets are coated in a thin NiCuNi protective layer preventing damage to the internal magnets and making them suitable for magnet fishing in the sea, rivers and dams.

Magnetic direction: North Pole in the centre & South Pole around outer edge
Comprises: 2 x Internal Neodymium Magnets, Steel Plate & M12 Eyebolt (304 Stainless Steel)

Interesting Fishing Magnet Information
The magnets Vertical Pull Strength Rating of 400kg 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 magnets vertical pull strength rating.
