Cartridges & CEW Operation
All TASER CEW deployments should be in accordance with current TASER training and warnings, and department
training, policies, and procedures.
Normally, aim the LASER at the preferred target areas of the body, which are the lower torso and legs when the
subject is facing you, or the subject’s back if the subject is turned away from you.
When possible, avoid intentionally targeting the CEW on sensitive areas of the body such as the head, eyes,
throat, chest/breast, or known pre-existing injury areas without legal justification.
The top probe is designed to impact the target near the top LASER beam but exact placement can vary depending
on numerous factors, including, but not limited to the distance, type of cartridge, and environmental factors.
Hold the X2 CEW so that the cartridge is vertical for an upright target. If both the upper and lower LASERs are
active, you should be able to estimate where each probe will hit.
NOTE: The LASERs are designed to coincide with the top and bottom probes of a 15' or 25' Smart cartridge at
15 feet. Thus, if your target is 15 feet away, and your CEW is loaded with a 25-foot Smart cartridge, the probes
will strike the target approximately where the LASERs are projected. If the CEW is being held perfectly vertical,
the top and bottom LASERs should be vertically aligned. If you are significantly closer or further than 15 feet to
the target, the LASERs will appear to be out of alignment. This is because the two LASERs are located almost 1
inch apart side-by-side on the CEW and zeroed to 15 feet.
With previous-generation TASER CEWs, the electrical current is relatively quiet in actual human use. Therefore,
the CEW may make very little sound when the probes are successfully deployed on a human or a conductive
target. With the X2 CEW, the noise level will vary. If a single cartridge is deployed and both probes make direct
contact with a human or animal and an electrical circuit is completed and maintained, the current will be relatively
quiet. Multiple cartridge deployments and Warning Arc displays are likely to make more noise than typical of
single-cartridge TASER CEWs.
Potential Causes of Reduced or No Effectiveness
• 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.
