TASER C2 Training Cartridges 2 Pack. The BLUE training cartridges are 15ft range training or ‘simulation’ cartridges. They contain a primer, gas capsule, probes, non-serialized tags and non-conductive wires. The BLUE training cartridges fire like a live cartridge but do not have the ability to cause neuro-muscular incapacitation and should not be used for self-defense. The training cartridge will not cause the metallic target to ‘crackle’ and ‘spark’ in a demonstration. Compatible ONLY with the TASER C2 series.
