Blue TASER Pulse training cartridges are 15 feet range training simulation cartridges. 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. They contain a primer, gas capsule, probes, non-serialized tags and non-conductive wires. The training cartridge will not cause the metallic target to crackle and spark in a demonstration. These training cartridges fit the TASER C2 and TASER Pulse models only. Use for Training Purposes Only. Not for Self Defense.
