|While the AIR TASER® 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-Wave® discharge — so you don’t have to worry about how long to hold down the button. Or, turn the unit on or off at your discretion. Because the AIR TASER® 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 TASER® requires no maintenance other than replacement of its 9-Volt alkaline battery when the battery indicator shows the battery is low.
