    Abstract: An improved emergency signalling device for use by skiers, hunters and other persons who may be exposed to the outdoors, remote from civilization, and who may in the course of their avocation or occupation become injured or disabled while far removed from contact with assistance. The device comprises a package, which may be secured by straps to a limb or the body of the person, the package containing a signal balloon, a helium container and a reel for paying out a length of tether line together with means for easily inflating the balloon with the helium and sending it aloft to attract the attention of searchers who may be looking for the person in distress.
