The Streetwise mini stun baton is a self defense device which disrupts the message the brain sends to the voluntary muscles. Simply touching an attacker with a stun baton for three to five seconds will deliver a high voltage shock causing loss of balance and muscle control, confusion, and disorientation bringing him to his knees and making him incapable of further aggressive activity. Full recovery takes about five to ten minutes and there is no permanent harm. Requires two 9 volt batteries. Measures 10 in. long. The Streetwise brand stun baton has more features than any other stun baton on the market. World's Strongest Stun Baton: at 750,000 volts, this is the highest voltage stun baton available. Just test firing this unit into the air is often enough to stop an attacker. As the bright electric current pulsates between the test prongs and creates an intimidating electrical sound an attacker with any sense at all will be stopped in his tracks. If the sight and sound doesn't stop them a jolt from this unit certainly will! Disable pin: prevents an attacker from taking this stun baton away and using it on you. A strap worn around your wrist attaches to a disable pin on the bottom of the unit. If this stun baton is taken away from you the disable pin will pull out, preventing it from working. Safety Switch: to prevent accidental discharge, three levels of safety have been built in. The disable pin must be inserted, the safety switch must be in the "on" position, and the trigger pressed down before the stun baton will operate. Holster Included: includes a heavy duty holster with belt loop for easy carrying. One Year Warranty: Streetwise Stun batons are one of the highest quality brands available and come with a one year warranty. Requires two 9-volt batteries (not included).
