Magnet fishing uses a strong magnet to try and grab ferrous metal objects that are hidden or lost underwater. If you want to try grabbing something lost on the bottom of a lake, pond, or river, a magnet on a rope might do the trick.
Our magnets with hooks consist of a neodymium alloy and are embedded in a steel pot, which increases the adhesive force and directs it down towards the surface. We carry small hooks with a diameter of 10 mm as well as large ones with 75 mm. The latter can hold a maximum weight of 600 kg when used on the ceiling (e.g. steel beams).
