🔍 Key Concepts

• EPIRB (Emergency Position-Indicating Radio Beacon) purpose and where it is carried • ELT (Emergency Locator Transmitter) and what type of craft usually carries it • PLB/PLBS (Personal Locator Beacon[s]) and who typically wears or carries them

💭 Think About

• Think about what all three devices have in common: when are they used and what do they send? • Ask yourself whether these devices mainly SEND or mainly RECEIVE signals in an emergency. • Consider whether GMDSS has eliminated these devices or if they still form part of modern distress alerting systems.

✅ Before You Answer

• Verify whether these beacons are transmitters, receivers, or visual devices. • Confirm if these beacons are meant to send electronic distress information rather than flares or lights. • Check whether current SOLAS/GMDSS rules still require or recognize EPIRBs. If yes, could they be ‘replaced’ by GMDSS?
