How Does a PLB Work? A PLB is activated, and a distress signal is transmitted from a PLB/EPIRB/ELT The signal is received by the COSPAS SARSAT satellites The satellites send the signal to the nearest receiving stations on earth known as Local User Terminals (LUTs)
What happens when you activate a PLB?
When a PLB is activated the emergency services have very little information and assume the need is urgent and life threatening Responding to a PLB may take resources away from other cases that are assumed to be less urgent
How do personal locator beacons work?
A personal locator beacon (PLB) uses the COSPAS-SARSAT global satellite system to send out an SOS alert Using GPS positioning, the 406 MHz distress frequency and 1215 MHz homing capabilities, the PLB, once the antenna is up and the button depressed, will pulse out its SOS alert
Is PLB single use?
PLBs are a single use device and the battery must be replaced after it has been activated
Can a PLB be used more than once?
If you are in a group, do not activate more than one beacon at a time When the first beacon’s battery goes flat then turn it off and activate the second one The battery life of a PLB is more than 24 hours, it is unlikely that rescue will take that long to arrive
Do I need to register a PLB?
PLB (Personal locator beacon) & EPIRBS (Emergency Position Indicating Radio Beacon) All PLBs and EPIRBs must be registered with the Maritime & Coastguard Agency EPIRBS are registered to a vessel so you will need to also give details of the vessel including the MMSI number, and call sign
What is difference between Epirb and PLB?
EPIRBs are designed specifically for maritime applications They quickly alert authorities as to the whereabouts of distressed vessels and their crews, while PLBs (as their name suggests) alert authorised as to the whereabouts of individuals
How accurate are PLB?
The COSPAS-SARSAT satellite network can detect the location of the PLB with an accuracy of 2 to 5 km Newer PLBs can have a GPS navigation receiver integrated into the distress signal These PLBs will transmit an accurate location The PLB also transmits a low-power “homing” signal on 1215 MHz
How accurate are personal locator beacons?
With a GPS the accuracy is generally within 100m It is recommended to purchase a beacon with GPS NOTE: Older 243/1215MHz beacons are no longer being monitored by satellites
Is a EPIRB better than PLB?
What is the Difference Between an EPIRB and a PLB? EPIRBs are larger than PLBs, usually have more battery life (they’re required to have a minimum of 48 hours of activation time versus 24 hours for PLBs), and they always have a strobe light built in, while PLBs may or may not have a strobe light
Can I use a PLB on a boat?
A PLB can be used on land and water and is an ideal size to be carried by mariners, bush-walkers, 4×4 and aviators An EPIRB alerts search and rescue services of a watercraft in trouble by transmitting a coded message on the 406 MHz distress frequency via satellite and earth stations to the nearest rescue centre
What is the best PLB in Australia?

Does PLB expire?
A PLB will last for 5 years in standby mode or 24 hours in operational mode Your manufacturer will tell you the battery life and expected operational time of your PLB You can find this by looking at the battery life of the PLB Once the battery expires, it needs replacing by an authorised service agent
Who monitors PLB?
In the United States the 406 MHz signal is monitored by the National Oceanic and Atmospheric Administration (NOAA) and the Air Force Rescue Coordination Center (AFRCC) Each PLB is equipped with a unique identifying code which is a 15 digit alpha-numeric code
Can you change the battery on a PLB?
You need to have the tools, hardware and software to perform a battery replacement Full functional testing is done on the unit after the battery is replaced, to ensure the unit will last another 5 years in the field The battery of a Personal Locator Beacon needs to be replaced by a trained technician
Why is the 406 MHz beacon important?
406 MHz beacons are digitally coded and transmit distress signals without delay This means that even a brief inadvertent signal can generate a false alert To avoid getting a call from the Coast Guard make sure that when you test your EPIRB you follow the manufacturer’s recommendations carefully
What are the key differences between an EPIRB and a PLB personal locator beacon which uses the same system as an EPIRB?
Due to its size, the transmission duration of a PLB is a minimum of 24 hours, whereas an EPIRB will transmit for a minimum of 48 hours and will float in the water As a PLB is a personal piece of equipment it should ideally be worn on the person or be integrated within the wearer’s Lifejacket
What is a 406 MHz beacon?
406 MHz beacons designed for use in an aircraft are known as an Emergency Locator Transmitter (ELT) ELTs can be manually activated by the pilot or automatically activated by a G-switch ELTs transmit for at least 24 hours and most have the 1215 MHz homing capability
Is Garmin InReach a PLB?
As I write this article, the Garmin InReach Explorer+ is one of my most expensive piece of hiking equipment However this device combines the functions of a GPS as well as a PLB so the price is not as expensive as it first appears and given all that it does, its a piece of gear I wouldn’t do without
What is a PLB for boats?
Personal Locator Beacons (PLBs) emit a distress signal in the event of an emergency offshore or on land EPIRBs are larger, can automatically deploy and activate if a boat sinks, and emit a distress signal for a minimum of 48 hours
Do EPIRBs have expiry date?
EPIRBs must be re-registered every two years with AMSA This ensures details are kept accurately, especially if someone has bought a different boat and previously forgotten to change details Beacons generally have a 10-year battery life and the entire beacon will need replacing after the battery expires
