Abstract: A remote initiator for the remote initiation of explosive charges. The remote initiator having: (i) a transmitter with means for generating and transmitting a coded signal and input means for inputting operational commands into the transmitter for generating the coded signal, (ii) at least one receiver adapted to be connected with the explosive charges, the receiver having means for receiving the coded signal from the transmitter and input means for inputting operational commands into the receiver for generating an output signal for the remote initiation of explosive charges upon receipt of a valid transmitted coded signal, (iii) a power source for each of the transmitter and receiver, and dual processing means that are independent of each other are adapted to provide independent control of a firing circuit and adapted to synchronise with each processing means before initiation can occur so as to enhance safety and reliability of the transmitter and receiver and the initiation of the remote initiator.
