TASERŽ ProductsWhile the AIR TASERŽ uses extremely advanced technology, it is simple to use: Simply pull back the safety slide and press the trigger. The AIR TASER microprocessor is programmed to administer a 30-second TASER-WaveŽ discharge so you dont have to worry about how long to hold down the button. Or, turn the unit on or off at your discretion. Because the AIR TASERŽ transmits pulses into the nervous system, a hit anywhere on the body can be effective. Thus, it is much easier to use than sprays or firearms which require a hit to a specific zone of the body. An optional laser sight provides laser illumination for pinpoint accuracy (and stronger deterrence). Yet, with all this technology, the AIR TASERŽ requires no maintenance other than replacement of its 9-Volt alkaline battery when the battery indicator shows the battery is low.
