HOW IT WORKS:
Once activated, SPOT will acquire its exact coordinates from the GPS network, and send that location along with a distress message to the GEOS International Emergency Response Center every five minutes until cancelled or until the batteries are depleted. The Emergency Response Center notifies the appropriate emergency responders based on your GPS location and personal information which may include local police, highway patrol, the Coast Guard, our country's embassy or consulate, or other emergency search and rescue teams as well as notifying your emergency contacts about the receipt of a distress signal.
Even if SPOT cannot acquire its location from the GPS network it will still attempt to send a distress signal without exact location to GEOS, which will still notify your contacts of the signal and continue to monitor the network for further messages.
