ACR ResQLink AIS PLB-450 GPS Personal Locator Beacon with AIS, RLS & NFC (2933)

The ACR ResQLink AIS 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. This version also transmits AIS alerts to compatible nearby marine receivers and supports NFC smartphone diagnostics.

Compatibility

USA-programmed PLB for individual emergency use. Register with the appropriate national authority. This is not an EPIRB with automatic vessel-sinking deployment. AIS distress reception depends on another vessel having compatible AIS equipment; the PLB does not float without an accessory flotation solution.

Installation & Setup

Register the beacon, inspect its battery replacement date and follow ACR self-test procedures. Carry it securely and ensure the antenna can be extended with a clear view of the sky. Use only for genuine distress situations.
