Abstract: A dry-fire training module for conductive energy devices and a method to determine the approximate trajectories of darts fired by live modules. The dry-fire training module snaps into the front of a live conductive energy device. The dry-fire training module is reversible to the conductive energy device. The conductive energy device can be fired with the dry-fire training module in place. A high voltage conductor eliminates the high voltage potential across the front of the conductive energy device. When the conductive energy device is fired, the sensor in the dry-fire training module detects the high energy pulse of the discharge and triggers two lasers within the module to emit beams of differing frequencies. The lasers are fired for a duration sufficient to be detected by a target sensor. The striking points of the laser beams against the target surface demonstrate the approximate striking points of the darts fired by live modules.
