The S-200 is a new breed of stun gun which promises more intelligent knock-down power than anything prior. With current stun guns, officers have found some individuals can fight through the muscle agony and still attack. On the other hand, the high-current pulses of these weapons have occasionally caused tissue damage and even lethal effects.

Stinger Systems believes a better approach is to incorporate "Pulse Groups Per Second" rather than traditional "Pulses Per Second." By spreading a less intense waveform over a longer period of time, the muscles contract longer. That means potentially less dangerous, yet more effective incapacitation.

The availability of new high-energy switching transistors is permitting the deployment of the best solution yet – Quantum Flyback Technology (QFT). The S-200's electrodes deliver high-voltage energy in a precisely controlled series of energy packets or "Quanta." The electronics delivers these energy quanta from a "Flyback" transformer circuit. Series of quantum pulses are delivered first as ionizing spark energy and then as a more immobilizing, lower-voltage, higher-current energy quanta once on target.
