The invention relates to a method of, and apparatus for, initiating the ignition of shock tubing. In one described embodiment a passageway, defined by a bore (13), is closed at one end and arranged with its open end (11c) adjacent an end (18a) of the shock tubing (18) to be ignited. The passageway includes two electrodes (12, 14), axially spaced within the bore (13), and an electrical circuit including a battery means (16) and a capacitor (17) is arranged to generate a spark between the electrodes (12, 14) to generate a high energy compression pulse within the bore (13), and which high energy compression pulse is directed by the bore (13) into the end (18a) of the shock tubing (18) to effect ignition of the tube (18). |
