This might be the sweetest device you hope you'll never have to use. The SPOT Satellite Messenger could quite possibly save your life.

The gps unit can be used to check in with friends and family, send a personalized distress message, or send for 911 rescue. Using satellites and SPOT emergency services, your location can be pinpointed even in areas where cell phone service is unavailable.

The unit is built to only send messages, not receive them, and is not the best choice for those more interested in GPS tracking units, but if you tend to spend a lot of time in the outdoors, back country or the wild, this could easily wind up being the most important gadget you carry.
