ABSTRACT:
An underwater demolition device has magnets for holding the device on a ferrous structure and a plunger which, once the device has been planted, is held in a retracted position by the structure on which the device is held. If the device is moved from the structure, the plunger protrudes beyond the magnets. A visual indication is provided immediately upon arming of the device if the plunger is then in its protruding position and a timer is provided to prevent detonation until a predetermined delay has elapsed from arming.
