The new Advanced Taser M-18series has almost 100% effectiveness rating. It combines the injury reducing benefits of traditional stun technology with a quantum leap in stopping power via new Electro-Muscular Disruption (EMD) technology. In police studies, the new Advanced Taser has a higher instant incapacitation rate than a 9mm hand gun. The Advanced Taser shoots out 2 darts attached to 15 feet of wire. 50,000 volts travels over the wires and over-rides the central nervous system providing incredible takedown power.
