Seismic Instantaneous Electric Detonators are supplied in No.8 strength with 23 SWG Copper wires. Seismic Instantaneous Electric Detonators consist of an aluminum tube closed at one end and to the other end are attached the copper wires. These detonators have a specially developed fuse head designed to go off within one milli-second of the current application. The fuse head is protected by a special anti-static sleeve.

Seismic Instantaneous Electric Detonators being fast action detonators, are capable of withstanding high hydrostatic pressure, meets the critical needs for seismic prospecting and therefore is specially developed for seismic exploration on land or offshore.
