Abstract
A device for providing location data for use by a lost child or adult or an individual in need of assistance. The device is in the form of a small compact unit including a container having a top case and a bottom case containing a deflated airfoil and a gas cylinder containing lighter-than-air gas such as helium. A release key which when pulled allows the top case to separate from the bottom case and automatic inflation of the airfoil commences. The plunger strikes a lever driving a puncture pin into the gas cylinder filling the airfoil through a one way valve. The airfoil is tethered at one end by a line and is attached to the bottom case and maintains flight even in adverse weather conditions.
