How many barbed projectiles (probes) does the electronic control device (ECD) neuro-muscular incapacitation (NMI) system use when fired?

The electronic control device (ECD) neuro-muscular incapacitation (NMI) system uses two barbed projectiles, commonly referred to as probes, when fired. This design allows the device to establish an electrical circuit between the two probes, which are intended to be deployed at a distance from each other, typically up to 21 feet or more. When the probes make contact with the target's body, they trigger a neuromuscular incapacitation effect by delivering an electrical charge, disrupting the communication between the brain and muscles, resulting in temporary incapacitation. Using two probes ensures a more effective connection to the target, maximizing the device's effectiveness in neutralizing a threat.
