ABSTRACT:
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's elements are contained within a case having easily separable halves.
