If you're a parent, you're probably familiar with the feeling of panic that arises when you lose sight of your child in a public place. After a seemingly endless couple of minutes of frantic searching, you usually find your kid hiding in a rack of clothes or striking up a conversation with a fellow 3-year-old. A child abduction alarm could spare you some undue panic -- and possibly stop your child before he or she goes too far. Yes, that's a scary name, but in all likelihood it will just help you curb chronic wandering. Your kid wears the transmitter around his or her neck, and you hold on to the receiver, which you can set for between about 6 and 30 feet (1.8 to 9 meters). It won't keep your children glued to your side at every minute, but at least you'll have peace of mind if they stray.
