It mainly consists of a high-grade neodymium magnet and a steel shell. The steel case is crucial for enhancing the magnetic force, it can concentrate the powerful magnetic field at the bottom of the magnet, which increases the magnetic force 2.5 – 4 times compared to the bare magnet. At the same time, a steel cup can prevent the exposed magnet from scratching and chipping during gripping and clamping.

The magnets are designed for heavy duty and underwater use. It can help restore lost equipment, tools, fishing gear and other black objects in deep water, wells, holes. It is also great for magnetic fishing, lifting, hanging and retrieving applications.
