The air taser is powered by compressed air cartridges which, when activated, fire two electrical probes into the clothing or skin of an opponent. The electrical probes generate a burst of electricity which causes would-be attackers to lose muscular control. The muscles contract involuntarily (think of the way your eyes briefly snap shut when you sneeze), and the attacker falls to the ground.
The electrical impulse from the taser disrupts information between the brain and the muscles, causing total lack of coordination. The air taser gun is built to deliver bursts of electricity over a short period of time so that attackers can't pull the probes from skin or clothing, giving you time to get away. Tasers can be fired from up to 15 feet away and are 99% effective, even on attackers under the influence of drugs or liquor.
It's not hard to fire a Taser: just aim in the general direction of your opponent, and fire. Unlike guns, the Taser doesn't require much training in order to get a good shot—and save yourself from attack.
The new Tasers C2 are smaller and easier to conceal and handle, so it isn't only the cops who like them. You can buy a small but powerful taser with a holster, or keep it in your pocket when you're walking in potentially dangerous situations. Knowing you have an effective, easy to use weapon at hand will increase your feelings of confidence as well as your objective safety.
