The Garmin inReach Mini GPS is a satellite communicator in a small, rugged size. Text with family, set up GPS-based location tracking, even connect to social media while out in the wilderness. No towers, no worries, this little guy is for off-the-grid connectivity. It even allows you to send SOS alerts in case the trip goes south and you find yourself in an emergency. All wrapped up in a tiny, 4" tall, 2" wide package.
