Datasheet
The Scorpion HB-320 is a powerful and rugged, compact light-weight Solid-State Electronic Capacitor Discharge Blasting Machine. The unit is completely sealed making it waterproof and impervious to dust, dirt, sand, and debris. It features EIT’s specially developed Heavy-Duty Push Down Binding Posts for quick and secure lead line attachment. The HB-320 incorporates 2 recessed covered pushbutton switches for Charge and Fire operations. For added safety, the operator must depress and maintain the “Charge” switch while the unit is indicating “Ready” to proceed to “Fire”, and in that order. This two-switch procedure ensures the operators intent to initiate. The Scorpion HB-320 offers rapid-charging and is engineered so that it may only fire when fully charged and maintaining verified armed specifications. Four AA batteries provide a lengthy service of Charge/Fire cycles. The battery pack loads smoothly through the side of the unit into a waterproof compartment secured in place by an easy-on/easy-off Battery Cap.
