Double the power, double the stopping power! Carrying the DOUBLE TROUBLE stun gun is like carrying two stun guns rolled into one. 2X the body contact, 2X the stopping power, and a whopping 1.2 million volts! Super-wide 5 inch contact spacing gives this unit more stopping power than your average stun gun. Soft grip rubber coating makes this stun gun easy to hold firmly and the safety switch with red "ready" indicator lets you know when you are ready to rock. This stun gun uses two CR123A lithium batteries (INCLUDED!) and comes with a free Nylon case and belt clip. This unit is 6 inches in length and only weighs 6.9 ounces.
