All TASER 7 Cartridges have a wire length of 25 feet, or 7.6 meters, so the angle determines the efficacy of the device when the cartridges deploy from various distances. The standoff cartridges have a 3.5 degree angle for longer distance shots. These are live cartridges and are distinguished by their black blast doors. Revolutionary Probe Design The wires are spun around the probes so that your shot is faster, straighter, and carries 2x the kinetic energy as previous weapons. This is designed to reduce clothing disconnects. Adaptive Cross-Connect Technology  Electricity is intentionally driven between all contacts to maximize the effectiveness of the probe deployment and to help compensate for close prove spreads or clothing disconnects. Smart Weapon, Smart Catridge The static-resistant TASER smart cartridge is more accurate and durable than a standard cartridge, which increases reliability and lowers the risk of accidental discharge
