These cool new satellite messengers from Garmin use the Iridium Satellite network to keep you in contact with family and loved ones whilst you’re out of normal cell coverage.
The two models available share the exact same satellite messaging functionality. However the main difference between the two models is the added topographic mapping capability of the inReach Explorer+. While the inReach SE+ is GPS enabled and allows you to mark waypoints and leave trails on a grid system, the Explorer+ model allows you to use preloaded topographic charts and use waypoint routing.
