ACR ResQLink 400 GPS Personal Locator Beacon (2921)

The ACR ResQLink 400 personal locator beacon gives individuals a dedicated emergency alerting device for boating and outdoor activities beyond reliable mobile coverage. Its 406 MHz satellite distress transmitter and GNSS receiver send an emergency alert with location information while a 121.5 MHz homing signal assists local rescuers. Its compact, buoyant design is convenient for personal emergency carry.
