Ready to go magnet fishing and see what treasures you can pull up from rivers, lakes, or ponds? This CMS magnet is a beast! It features a super powerful neodymium (rare earth) magnet housed inside a chrome-plated steel cup. That design concentrates the magnetic force, giving it an impressive 78kg (about 172 lbs) of pulling force on a clean, smooth steel surface. The steel cup protects the magnet and makes it last way longer than exposed magnets. It comes as a complete kit with a threaded eye bolt that screws directly into the cup – no need to assemble separate parts. Just attach a strong rope to the eye bolt (pro tip: use a thread locker to keep it from unscrewing!). It's perfect for hobbyists looking for coins, tools, or historical artifacts underwater. Strong enough to grab stuff, but not so monstrous that you can't retrieve it if it gets stuck on something huge. A fun, powerful tool for outdoor adventure.
