Feature:1. With Ni + Cu + Ni three-layer coating, the magnetic force is strong and permanent2. Epoxy resin is used instead of the original plastic ring to make it more tight and provide protection for the magnet, helping to prevent chipping or cracking.3. Magnetic force level is N35, with strong magnetic force and high bearing capacity4. The magnet is suitable for river fishing and searching, recovering lost or discarded items and historical relics, etc.5. Strict quality control and quality assurance, high safety factor, can be used with peace of mindSpecification:Item Type: Salvage MagnetMaterial: MagnetMaximum Load-Bearing: 357LBS / 162KG (the adsorbed iron is flat without unevenness, and the thickness is more than 3cm to achieve the maximum load-bearing tension)Magnetic Level: N35Diameter: Approx. 75mm / 3inThickness: Approx.15mm / 0.6inWeight: Approx. 557 g / 19.6 ozSalvage Rope Length: Approx. 20 meters / 65.6fSalvage Rope Color: RedPackage List:1 x Salvage Magnet1 x 20 Meters Salvage Rope
