Both stun guns and Tasers emit electrical currents and are used to temporarily immobilize assailants. But stun guns work only by coming into direct contact with the assailant. Meanwhile, Tasers can be deployed from a distance through shooting probes to deliver the shock. Tasers fit into Arizona's definition of remote stun guns: 'Remote stun gun means an electronic device that emits an electrical charge and that is designed and primarily employed to incapacitate a person or animal either through contact with electrodes on the device itself or remotely through wired probes that are attached to the device or through a spark, plasma, ionization or other conductive means emitting from the device.'
