- Loose or Thick Clothing. If the probes lodge in clothing and are too far away from the subject, CEW effectiveness is reduced and can be eliminated.
- Miss or Single Probe Hit. The electrical current must pass between a positive probe and a negative one (Top and Bottom Probe) in a completed and maintained circuit. If one probe misses, a second cartridge may be deployed, if practical and justified, to complete the electrical circuit. Also, using the X2 CEW in the drive-stun mode may complete the circuit between the single probe and the CEW electrode.
- Low Nerve or Muscle Mass. If the probes impact in an area where there is very little muscle mass (e.g., the side of the rib cage), the effectiveness can be significantly diminished.
- Limited Probe Spread. Probe spreads of less than 4-9 inches/20-23 cm (including drive-stun) may result in little or no incapacitation effect and become primarily a pain compliance option.
- Wires Break. If a wire breaks (e.g., during a struggle), the current will not flow to the probes and an additional deployment may be required. Drive-stun may still be available. Do not become over-dependent on the TASER CEW. No force option, including CEWs, is 100% effective in every situation. Do not deploy the CEW without following your department policies and procedures.
