The 20kg Magnet Pad Assembly fixes charges to steel targets and is the core of the Vulcan Counter Limpet Mine System™. Rated at 20kg, it holds close to 25kg.     Each magnet sits in a plastic base plate, with a plastic bolt extending from the back. The bolt fixes the pad to accessories such as the underwater stand and the Cable Reel. Fit a plastic eye bolt instead, and the pad becomes an anchor point for hook-and-line techniques or marker lines.
