The Compact Rescue Signal Device is designed to help lost or stranded hikers. This device is approximately the size of a small flashlight and comes in a variety of colors. When activating the lever a 30 Mylar balloon imprinted with the letter SOS is filled by a lighter than air gas. From this stage the balloon can be deployed and become more visible on the attached 75 foot tether to aid in the quicker recovery of lost or stranded hikers and helping to lower cost of state and federal rescue operations. Also included is a reflective disk on the outer cap of this device to assist when needed. The design of operation is easily operated by children and adults and light enough to carry in a pant pocket or small daypack.
