Shocktube Initiator Model STI-2

Overview and features

This unit directly fires Shocktube when inserted into the Shocktube adapter and the correct firing procedure is followed.


  • Attach the Shocktube adapter to the Initiator and place freshly cut Shocktube into the adapter.
  • Turn and hold the FIRE key switch. The Initiator will fire within 1-4s.
