VLF or very low frequency transmitters are used by submarines to receive and transmit data because of their ability to transmit through most media. This is important because it allows the user to transmit and receive data through water, snow, or even rock. In this invention, a user would carry a small vlf transmitter coupled with a Global Positioning System (GPS). The GPS is used to determine the coordinates of the user. By tracking satellites, the GPS can determine longitude and latitude of an individual. In this invention a user would carry a small VLF transmitter coupled with a GPS. Although this is existing technology, the use of these technologies together has not been done. If a hiker or skier was in an accident, he/she could activate the VLF/GPS. The invention would then determine the location of the user with the GPS. If it can determine the location, then it would transmit the location on a packet with a unique key(address) for the device. The transmitter would also send the temperature and pulse of the individual through sensors which are used today in other inventions. These small sensors are cost effective, and are commonly used in sports watches. This would allow a listening location to monitor the person in distress, and possibly locate the user. 1
