I like the additional security feature of shut-down clock.
"Battis’ dazers include a countdown clock that shuts the device down once a set time expires. An officer would begin his patrol by programming the dazer’s security code, turning the tool on. The weapon then remains on until the internal timer reaches zero — turning the dazer automatically off. Programming would repeat each time the unit is required to be turned on. While on, the Dazer requires the user to press the trigger or button to activate."
