Practical and economical. Made of super-tough delrin and nylon with all steel firing mechanism. Well made yet thrifty tool.
The Scorpion "HR" models are mechanical initiators designed for initiation of non-electric blasting systems.
Utilizing the energy release of the Remington #209 shotgun shell primer which is readily loaded into the HR's breech block, it can be readied for operation in just a few seconds. After cocking and loading, with the flashguard in place to protect the blaster, non-electric tubing is inserted into the barrel of the nozzle and the device is ready to initiate the blast by simply flipping the trigger from its cocked position.
