Because of their power and extended reach, STUN MASTER® STUN BATONS are a favorite among security guards. Simply touch an assailant with the baton and pull the trigger: three to five seconds will leave the assailant dazed and temporarily paralyzed. The baton will also deliver a shock when touched six inches from the tip, to prevent an assailant from taking it away. Rubber handle. Powered by two 9-volt Energizer Eveready alkaline batteries (not included). LIFETIME WARRANTY. 500,000 Volts 20 inches long
