When traveling outside of the country or exploring remote areas, 2 way communication is vital. There are more areas on this planet without cell service than you may think. So that shiny iPhone in your pocket can quickly become useless without a signal. I often kayak in the Great Lakes and find myself out of range with my phone. The Spot X 2-way messenger is a handy device to bring along. Using satellite communication, the Spot X device plus a data plan will allow you to message family and friends from anywhere. But the real purpose of this device is direct communication with Search & Rescue services in case of a life-threatening emergency. So the next time you head out on an adventure, or visit a country with limited cellular service, the Spot X 2-way messenger has your back.
