With new transistor switching technologies, Stinger has created a revolutionary new approach to immobilization technology.  Rather than have a large dump of initial current and energy into the body (current is what is dangerous to humans)  the Stinger S-200's microcomputers allow for LESS current in the initial blast and smartly regulates the output energy thereafter.   The results are less pain and great immobilization. A study showed that the Taser® X-26® put approximately 75% higher peak current than the Stinger S-200 into the chest, "It's not the volts, but the amperes that matter for electrical safety"---Taser International sales brochure.
