The SPOT Personal Tracker is included on Time Magazine's list of the 100 greatest and most influential gadgets.
Ranked among the obvious choices of iPod and iPhone, Kindle and BlackBerry, the economically priced GPS device is touted as the world's first satellite GPS messenger by Spot LLC. The tracker allows the families of boaters and outdoor enthusiasts to keep tabs on roaming relatives, who can send alerts if they're in danger or let loved ones know they're all right.
The list was chosen by Time tech editor Peter Ha.
"Your cellphone doesn't always work and satellite phones are costly for the average outdoorsman. And let's face it, distress beacons are typically reserved for airplanes and large ships," Ha writes of the device.
