The Scorpion HR-3 is a mechanical Non Electric Initiator which utilizes a #209 shotgun shell primer to initiate Shock Tube. EIT’s originally patented Retainer/Breach combination offers safe and simple quick loading of the #209 primer. When ready to initiate, the user loads the Shock Tube through the Flash Guard and into the brass Breach. The Cock Pin is pulled back and into the locked “Safe” position. To Fire, the Cock Pin is released allowing the firing pin to spring forward striking the #209 primer which in turn initiates the attached Shock Tube The HR-3 is a tough and reliable unit with a body and Flash Guard constructed of Stainless Steel and 6061 Aluminum. A chain connects the Retainer to the Breach so that these items remain together. The HR-8 comes with a removeable Safety Pin that prevents the unit from firing, and the HR-8 incorporates a D-Ring attachment on its base for a factory supplied carabiner clip.

E.I.T. HR Mechanical initiators are designed for initiation of non-electric blasting systems.
