There are places where phones won’t work, and if you need help you might find yourself reduced to smoke signals –unless you have the SPOT Satellite GPS Messenger. This rugged, pocket-sized device works where mobile handsets will not, and offers users the ability to send real-time, on-the-fly messages via text or social media. It features an option to allow your location to be transmitted in real-time. It can help notify emergency responders locate you in a pinch, but can also be used to just “check in” while you’re otherwise off the grid.
