Using the worldwide coverage of the Iridium satellite network, these go-anywhere portable devices let you exchange text messages with any cell phone number or email address anywhere while using GPS to track and share your journey's progress. You can also post to social media or even communicate inReach-to-inReach in the field.

In case of an at-risk situation, you can also use inReach to trigger an SOS to the 24/7 monitoring center, text back and forth about the nature of your emergency, and receive confirmation when help is on the way.

Turn on the tracking function of your inReach SE+ or Explorer+ communicator, and let family and friends follow your progress on their computers or mobile devices, using the web-based MapShare portal. The inReach device will send waypoints at preselected time intervals, so followers can track your whereabouts online. You can also invite your crew back home to use MapShare to ping your inReach unit and see your GPS location, track your movements and exchange messages during your trip.

The optional inReach weather forecast service provides detailed updates directly to your inReach device, compatible smartphone or tablet paired with the Earthmate app, so you'll know what conditions to expect en route. Basic and premium weather packages are offered. And you can request weather forecasts for your current location or any other waypoint or destination on your itinerary.

GEOS is the world leader in emergency response solutions and monitoring. They've supported rescues in more than 140 countries, saving many lives in the process. And they're standing by 24/7/365 to respond to your SOS, track your device and notify the proper contacts and emergency responders in your area. Then, while help is on the way, GEOS will continue to text back and forth with you, providing updates and critical information until your situation is resolved.

As satellite communicators, both the inReach SE+ and Explorer+ offer identical messaging capabilities. However, it's on the GPS navigation side that their differences become apparent. While inReach SE+ uses GPS to provide basic grid navigation and allow you to drop waypoints, mark key locations, track your progress, and follow a breadcrumb trail back to base, the inReach Explorer+ goes a step beyond, providing full-fledged GPS on-map guidance with preloaded TOPO mapping and waypoint routings viewable directly on the unit. Plus, a built-in digital compass, barometric altimeter and accelerometer are included with Explorer+ to help you get and maintain accurate bearings anywhere on or off the beaten path.

Every inReach device comes with free access to a cloud-powered portal to plan your trips with routes and waypoints, create preset messages and quick texts, sync and manage your device settings, update your firmware, download additional TOPO maps, link your social media accounts, store all your location tracking data and much more.
