Are There Specific Regulations For EPIRBs Vs PLBs?

April 5, 2026

Quick Answer

EPIRBs and PLBs have specific regulations, particularly regarding their use in emergency situations at sea. EPIRBs are typically used for emergency situations at sea and require registration, while PLBs are used for personal use and do not require registration.

EPIRB Regulations for Emergency Situations at Sea

EPIRBs (Emergency Position-Indicating Radio Beacons) are regulated by the International Maritime Organization (IMO) and the Federal Communications Commission (FCC) in the United States. To activate an EPIRB, you must be at least 1 mile offshore, and the device must be registered with the relevant authorities. Failure to register can result in fines of up to $50,000. EPIRBs also have a 48-hour battery life, which is designed to provide emergency responders with a location.

PLB Regulations for Personal Use

PLBs (Personal Locator Beacons) are regulated by the FCC and are primarily used for personal use in emergency situations. Unlike EPIRBs, PLBs do not require registration, but they do require a subscription to a emergency response service. PLBs typically have a 24-hour battery life and are smaller and more portable than EPIRBs. They are designed for use in remote areas, such as wilderness or mountainous regions, and can be activated in emergency situations.

Understanding the Differences Between EPIRBs and PLBs

Understanding the regulations and differences between EPIRBs and PLBs is crucial for safe and effective use. When choosing between an EPIRB and a PLB, consider the specific use case and the environment in which you will be using the device. If you are at sea, an EPIRB is likely the better choice, while for personal use in remote areas, a PLB may be more suitable. Always follow the manufacturer’s instructions and local regulations when using either device.
