Final answer:
Spark testing is recommended on the TASER X26 ECD to ensure functionality and proper safety. It can help with muscle memory and practicing, but the main purpose is to verify the ECD's performance.
Step-by-step explanation:
Spark testing is recommended on the TASER X26 ECD to ensure that it is sparking properly. In a spark test, the ECD is discharged into a spark test target to confirm its functionality. This is important for ensuring the ECD is working correctly when needed. While spark testing can create muscle memory and help with practicing drawing and holstering the ECD, these are not the primary reasons for conducting daily spark tests. The main purpose is to verify the functionality of the ECD.
