    • SEISMICSTAR II

      Insensitive Instantaneous Electric Detonator                   
      for Seismic Prospecting
    • DESCRIPTION

      SEISMICSTAR II detonators are specially designed to provide the precise control that is necessary to achieve accurate seismic records from pattern shooting. The reaction time is shorter than 1 ms between application of current (minimum 6A for detonators connected in series) and firing of the detonator. In addition to their overall dependability, the detonators are easy to handle and possess excellent storage characteristics. A high level of protection from electrostatic discharge and water pressure is provided.

    • BENEFITS

      - High initiation strength - 720 PETN / RDX base charge ensures reliable initiation of all cap sensitive explosives.
      - 7.3 - millimeter diameter copper shell resists corrosive environments such as salt and brackish waters.
      - No fire current of 0.45 Amperes provides additional protection from stray electric currents.
      - Antistatic 100% moulded rubber sealing plug providing water tightness over extended sleep time.
      - There is a minimal lag time between bridge-wire rupture and firing of the detonator. Reaction is less than
      1 ms time when fired using 5 to 10 amperes DC.
      - Resistant to temperature extremes from -30 to +80°C.
      - Temperature stability at 75°C / 48 hours.
