Features 1、[Super Strong Magnetism] The bottom of the magnet has a strong magnetic force, which is equivalent to 10 times that of an ordinary magnet with the same volume, and the pulling force can up to 374.8lb. 2、[3 Layer Coating] The 3 layer coating of oil on the magnet surface, which is both glossy and rust resistant, helps prevent the magnet from chipping or cracking. 3、[Stainless Steel Material] Except for the bottom of the magnet, the other three surfaces are protected by stainless steel, which has almost no magnetic force, ensuring that it will not rust when working underwater. 4、[With Lifting Ring] The magnet has a unique countersunk hole and eyebolt design, which can be threaded to ensure that the magnet is not lost, which is very suitable for salvaging underwater. 5、[Main Application] This powerful magnet is ideal for underwater salvage, lifting, suspension and recovery applications.
