A child locator that enables a parent to locate a child includes a master unit for wear by a parent and a monitored unit for wear by a child. The master unit may actuate an on-board alarm when its processor determines that the monitored unit is beyond a first predetermined distance and may actuate an alarm on the monitored unit when the separation distance is beyond another distance. The first and second predetermined distances may be the same of different. The child locator may also actuate the monitored unit manually and the alarms may be audible or visual. Once an alarm on the monitored unit is activated, a signal from the master unit is required to deactivate it. The master unit may include a directional antenna for determining a position on the monitored unit. The monitored unit may deliver voice data to a speaker at the monitored unit.
