600kg double sided Neodymium Fishing Magnets with both eyebolts
Search magnets, also called as treasure salvage magnets or retrieving magnets, which look like pot magnets, are also made up of neodymium magnets, rubber and steel housings and other components. But their sizes are usually larger than pot magnets, and, the machining method of their steel housing is different from pot magnets’. Search magnets are used for searching ferrite things in river, sea, or other places.
search for finds of iron at the bottom of rivers and reservoirs in cellars and caves in wells and cellars land in the dumps under bridges and crossings on the site land clearing debris from the iron collecting modern coins from the water (many coin magnets!) rise drowned valuable items (fishing gear, hunting rifles, etc.)
Modern Permanent Magnets can attract steel objects or other magnets from large distances and cause trapping injuries. Strong magnets should not be given to children. Many Magnets are brittle and may shatter if they are allowed to ‘jump’ together or they jump onto a steel surface. Strong Magnets may affect or interfere with sensitive electronic instruments. Always keep magnets at least 50mm from such devices. Magnets can destroy information stored on magnetic media such as credit cards, floppy discs and computer hard drives. Keep them at least 20mm away. Analogue watches, televisions and computer monitors can be permanently damaged by placing magnets near them. Users of heart pace makers should avoid being near magnets. Do not use magnets in explosive atmospheres
