Abstract
A system is disclosed that remotely activates one or more explosive charge by sympathetic detonation (i.e., not requiring explosives to be interconnected by wire). The system includes electronics that control the activation of each explosive charge and which are responsive to an acoustic sensor, a seismic sensor and a hydrophone sensor. In one embodiment an RF transmitter, which prior to detonation of an explosive charge, sends a wake-up signal to another system for a sequentially controlled sympathetic detonation of one or more explosive charges.
