The Band-It prevents prisoners from grabbing any sort of weapon from law enforcement personnel. The device consists of an electronic cuff that is placed on the subject, and delivers an immobilizing shock if the subject attempts to attack anyone. The shock can be delivered by an operator up to 150 feet away through a wireless remote. The Band-It from Stinger Systems emits 45,000 to 50,000 volts at 4 to 6 milliamps output, which is enough power to temporarily immobilize a prisoner. The Band-It has been approved for use by the U.S. Department of Justice and adopted by the U.S. Marshals Service, the Federal Bureau of Prisons, and many state and county agencies to prevent violence during the transportation and court appearances of potentially dangerous inmates or defendants.
