The Taser C2 is an Electronic Control Device (ECD) that delivers an incapacitating pulse that overrides the sensory and motor functions of the nervous system. This Neuro Muscular Incapacitation (NMI) technology can stop even the most aggressive individuals, including those under the influence of drugs and/or alcohol. The C2 ECD uses a replaceable cartridge containing inert, compressed nitrogen to fire two small probes that are attached to 15 foot insulated conductive wires. Energy is sent over the wires into the probes, which can penetrate up to two cumulative inches of clothing, or one inch per probe. The charge is transmitted between the two probes, jamming sensory and motor functions, and inhibiting muscular control. This NMI effect continues in 30-second cycles each time you press the trigger. The C2 ECD can also be used as a direct contact stun device. Civilian C2 models are available in different colors and options. (Taser; 800-978-2737; taser.com)
