Garmin inReach Messenger SOS Satellite Communicator

The Garmin inReach Messenger SOS Satellite Communicator is a pocket-size two-way satellite messenger for divers, boaters and backcountry travelers who go beyond cell coverage, offering text messaging and interactive SOS over the 100% global Iridium satellite network with an IPX7 water rating and a rechargeable built-in lithium-ion battery. It is offered in two models: the inReach Messenger Plus (010-02887-00), which adds photo and voice messaging, and the base inReach Messenger (010-02672-00). An active inReach satellite subscription is required.

Who it is for

This is for the diver or boat crew heading offshore, the liveaboard traveler crossing remote coastline, and the hiker, kayaker or expedition driver who needs a confirmed message path when phones stop working. It suits anyone who wants an interactive SOS to Garmin Response, the 24/7-staffed international coordination center, plus live tracking so people at home can follow the trip. Core messaging and SOS work on the device itself, so it still functions if a paired phone battery dies.
