The TASER X26C and TASER M26C Electronic Control Devices (ECDs) are modeled after our law enforcement-grade TASER X26 and TASER M26. Equipped with field-tested TASER technology, both models now bring you the unprecedented take-down power trusted by thousands of police officers every day. The X26Cand M26XC use propelled wires to deliver an incapacitating pulse that overrides the sensory and motor functions of the nervous system. This powerful Neuro Muscular Incapacitation (NMI) technology can stop even the most aggressive individuals, including those under the influence of drugs and/or alcohol. They use a replaceable cartridges containing inert, compressed nitrogen to fire two small probes that are attached to 15 foot (4.5 meter) insulated conductive wires. Energy is sent over the wires into the probes, which can penetrate up to two cumulative inches of clothing. The charge is transmitted between the two probes, jamming sensory and motor functions, and inhibitting muscular control. This NMI effect continues in 5-10 second cycles each time you press the trigger. The X26C and M26XC can also be used in direct contact stun mode if necessary. The X26C is also software upgradeable via its integrated Digital Power Magazine.
