The new advanced taser m 18 series 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 taser m 18 has a higher instant incapacitation rate than a 9mm hand gun and several other weapons. The advanced taser m 18 shoots 2 darts attached to 15 feet of wire through the air towards the target. 50,000 volts travels over the wires and over-rides the central nervous systems providing incredible takedown power.
