Made up of N42 neodymium magnet embedded a steel shell, it concentrates the magnetic field on the bottom and top of magnet which increase the magnetic force by 2.5-4 times compared to the naked magnet. The steel cup will prevent the naked magnet from crackings and chippings. Designed for heavy duty and underwater use, it can recover lost equipment, tools, ancient ferrous object and others in deep water, wells, holes, also great for lifting, hanging applications. Specification 1. Material: Neodymium Magnet N42+A3 Steel+Black Resin 2. Size:D5.31''×1.57''(T) 3. Vertical Pull-force 2100LBSHorizontal Pull-force: 480LBS for each side(Two Side Attracting Surfaces) On Base of 1.58" thickness Steel Plate 4. Max Working Temperature:80℃5. Package Included: One fishing magnet+ one M10 eye-bolt. Note: 1.The 2100LB is the vertical magnetic pull-force which makes the magnet pull way from the 1.58"thickness steel plate of a tensile tester under ideal condition. It does not mean the actual weight which the fishing magnet can lift The actual pull force will vary mainly depending on the following variables: A: Steel thickness (The thicker the steel is, the stronger the pull force) B: Attracting position (The farther beyond the center of gravity of the attracted object, the lower the pull force). C: Pulling direction (The smaller the angle taking 90° as a standard, the stronger the pull force), the Pull force in horizontal direction is only about one third of that in vertical direction) 2.When the fishing magnet attract tightly iron metals and could not be removed by hand, turn the long eye-bolt gradually to make it Pull away from the targeted ferrous object.
