ApplicationIt is mainly made up of a high grade neodymium magnet and a steel shell, the steel shell is crucial to amplification of magnetic force, it can concentrate the powerful magnetic field on the bottom of magnet which increase the magnetic force by 2.5-4 times compared to the naked magnet. At the same time, the steel cup can prevent the naked magnet from scratch and chipping during grabbing and clamping. Death Magnet retrieving magnets are designed for heavy duty and underwater use. It can help to recover lost equipments, tools, fishing tackles and other ferrous objects in deep water, wells, holes. It is also great for magnet fishing, lifting, hanging and retrieving applications.Specification1. Model: Double Sided Fishing Salvage Magnet 2. Material: Neodymium Magnet + Steel + Black Resin 3.
