With the SPOT GPS unit you will be able to send out your coordinates to a satellite which will transmit that signal to the rescue personnel and to those who you want to be informed in times when you need help. It is very simple to use. Very few buttons are present as shown in the above photo. One is for turning this GPS unit ON/OFF, the other one is to send a signal indicating that you are OK, help call button and the last one os for the worst case , the 911 button when you really need some serious help.
No matter where you are located, this small SPOT GPS unit works world wide with a very minor annual fee for using satellite services. Another plus is that when ever you hit the signal key it sends your location to the person you want along with a Google map link so that the person can know your exact location.

This SPOT GPS device sends your coordinates at regular intervals so that when you come back you can trace your entire route.
