This is the civilian version of what you hear about on TV and the News all the time. No, they do not kill anyone, but they'll sure mess up their day! The ADVANCED TASERbrand non-lethal weapon is a conducted energy weapon that utilizes compressed nitrogen to shoot two small probes up to 15 feet. These probes are connected to the weapon by high-voltage insulated wire. When the probes make contact with the target, the ADVANCED TASER brand non lethal weapon transmits powerful electrical pulses along the wires and into the body of the target through up to two inches of clothing. NEW Electro-Muscular Disruption (EMD) Technology There are two categories of energy weapons: Stun weapons and EMD weapons. STUN WEAPONS: Traditional stun technology weapons operate in a 7-14 Watt range and interfere with the communication signals within the nervous system of the target. These stun systems primarily effect the sensory nervous system. Like static on the communication lines between the brain and the body, stun systems interfere with the human command and control systems. However, a small percentage of people with a very high tolerance for electrical stimulation can fight through the effect of these 7-14 Watt systems. EMD WEAPONS: EMD weapons use a more powerful 18 to 26 Watt electrical signal to completely override the central nervous system and directly control the skeletal muscles. This EMD effect causes an uncontrollable contraction of the muscle tissue, allowing the M-Series to physically debilitate a target regardless of pain tolerance or mental focus. The ADVANCED TASER M-Series are EMD weapons -- specifically designed to stop even the most elite, aggressive, focused combatants. Rather than simply interfering with communication between the brain and muscles, the ADVANCED TAZER EMD systems directly tell the muscles what to do: contract until the target is in the fetal position on the ground. The ADVANCED TAZER provides for maximum safety for both the officer and the subject by bringing dangerous situations quickly under control before force escalates to lethal levels.
