DEFCON 1 Ultra also features a four-digit resettable combination dial versus the three-digit dial in the original

DEFCON 1. The addition of the fourth dial in the DEFCON 1 Ultra increases its security protection by increasing

the thief’s total combination search time to be 10.5 times more difficult. 

 
Another new feature to DEFCON 1 Ultra is the combination dial reset button. It’s an easy to find and simple to

use resettable button on the upper right side of the unit. So now security can be simple!

Now you can prevent notebook theft, the fastest growing fear among mobile professionals today. With the

Targus DEFCON 1 Ultra on guard, you can relax in airports, restaurants, and other public places. It's the only

system that combines stainless steel cable with motion sensor technology and a 95db alarm to create a

combination locking system that easily attaches to your notebook or carrying case in any setting.
