The alarm will trigger automatically in a Man Overboard (MOB) event. Should someone go overboard, the app, after sounding the alarm, will automatically provide lat/long coordinates of the MOB event, the time of the event, and will visually guide the rescuer using the virtual MOB compass.Key Features 30 times faster than AIS: Alarmed and ready to guide your rescue in three seconds; Intuitive rescue guidance, no input requiredFor Everyone: Your spouse, your kids or even your dog; Equip the entire crew for the price of a single EPIRBTwo beacons included; Smartphone or other mobile device not includedFree app operates on most smartphones or tabletsand is easy to use No cell service required Automatically updates with new features (both appand beacon) One smart device watches up to five crew members Activates with water immersion OR separation from vessel Rescue: Shows crew overboard bearing, plus distance and lat/long coordinates at point of loss Bearing adjusts as boat moves and "virtual MOB Compass" points to location Winner, 2017 Sail MagazinePittmann Innovation AwardCompatible SmartphonesRecommended for use with iPhone 5 and later, Samsung Galaxy S6 and later, Sony Z2 and later
