The Freedom GPS watch comes in adult and child sizes. The kids’ sizes are for ages 5-13 and are available in various colors. It includes a locking strap that uses a SureLok(tm) system. The size of a designated “mobile safe zone” can be adjusted. When the wearer leaves the safe area, it activates an alarm and a visual alert. Alerts by email and text messages linked to Google Maps are also available. The person may request assistance by pressing a panic button on the watch. Requires a monthly service fee.
