The air taser is a small personal protection device that utilizes compressed air to shoot two small probes at an attacker who is up to 15 feet away. These probes are connected by wire back to the handheld power handle. An electric signal is automatically transmitted along the wires to the body of the assailant, which usually incapacitates the assailant.
The air taser sends a series of electrical signals called t-waves, which are like those used by the brain to communicate with the body. These signals overpower the normal electrical signals within the body's nerve fibers. The human target instantly loses control of his or her body and cannot perform coordinated action, falling to the ground.
The entire human body is an effective target for the air taser. Because the t-waves can penetrate approximately 2 cumulative inches of clothing, the probes do not have to penetrate the flesh or cause bodily harm to be effective.
Studies have confirmed that there are no long-term effects from being stunned with an air taser. The air taser’s output power is at approximately 1/1,000th of a potentially dangerous level. A study performed at the University of Southern California Medical Center concluded in addition to its non-lethality, the taser leaves 0% long-term injuries. Tests have also confirmed that the t-waves do not affect the heart or damage an implanted pacemaker. The air taser may be carried legally without a permit in most states.
The air taser is a relatively large, awkward device. Unlike the stun gun, you do not have to be in close contact with your assailant to use it, but you only get one shot. You must remove it from where you are carrying it, accurately point it at an assailant, and both probes must contact the assailant for it to work. If this is your only line of defense, you may have problems defending yourself in most situations.
