Stun master stun batons are one of the most popular self defense products among security guards because of their extended reach and stopping power. Stun master stun batons have the same effect as a baseball bat. Three to five seconds of contact will leave an attacker dazed and temporarily paralized. The stun baton will also deliver a shock when touched six inches from the tip to prevent an attacker from taking it away. Potent stopping power and extended reach make stun batons ideal self defense products. Rubber handle. Powered by two 9-volt Energizer Eveready alkaline batteries (not included). Lifetime Warranty.
