a locator device used to provide location information for a user . the device comprises a case containing a deflated airfoil and an inert gas cylinder . the inert gas flows into the airfoil upon puncture of the cylinder by a valve having a puncture valve . the valve is operated by a twist from a user . the twist of the valve causes the puncture valve to be driven into the gas cylinder , thereby puncturing the gas cylinder . the gas flows into the airfoil until it is fully inflated . the inflation of the airfoil automatically pulls a pin from a quick - release assembly thereby allowing the airfoil to be released and deployed upon full inflation . the airfoil is anchored to the area of the user by attachment to the invention . all of the invention &# 39 ; s elements are contained within a case having easily separable halves .
