What is a common cause of limited Taser effectiveness?

One dart hit or missed deployment can significantly reduce the effectiveness of a Taser. For a Taser to properly incapacitate an individual, both darts must make contact with the target. This is because the Taser operates on the principle of creating a circuit through the body to deliver electrical impulses that disrupt muscle control and motor functions. If only one dart hits, there may not be a complete electrical circuit established, making it less effective in incapacitating the target. Additionally, if a deployment fails entirely—meaning both darts do not effectively strike the target—there will be no incapacitation achieved at all. In contrast, even though strong clothing or a high body mass index can indeed influence Taser performance, the immediate issue with limited effectiveness arises primarily from the dart deployment itself. Multiple dart hits could actually enhance effectiveness instead of limiting it, assuming both darts make proper contact.
