There are several variations of the equipment. In some cases, if the device goes outside a prescribed area, i.e. the home, it gets too far from a base station and an alert is sent to a monitoring station. Often the offender is allowed to leave but only with permission so he/she calls into an office, advises what they are going to do, and then go does it. If not back within a prescribed time, an alert is sent.

Another method uses a GPS and transceiver to send a signal to a monitoring station advising as to the location of the device, 24 hours a day, 7 days a week. The monitoring office records the route and then the offender's probation officer can see where the person has been. The location can also be seen immediately if they want to monitor real time.

Could make for one helluva way to keep track of a ball game.
