Taser CEWs use replaceable cartridges containing inert, compressed nitrogen to fire two small probes which are attached to 15 feet (4.5 meters) of insulated conductive wire. Energy is sent through the wires into the probes, which can penetrate up to two cumulative inches of clothing giving you a self defense product you can count on. The charge is transmitted between the two probes and is designed to jam the sensory and motor functions to inhibit muscular control. The NMI effect continues in 10 second cycles each time you press the trigger. The X26C CEWs can also be used in direct contact stun mode.
