Personal Locator Beacons (PLB) for Remote Area Rescue
What’s a Personal Locator Beacon (PLB)? Why not just get a sat phone? After all, many of us have been led to believe that satellite phones are the best modern way to get help in remote areas
Whilst they have great features, capabilities and functionality, they may not be the best solution for every explorer, hiker or prepper. It is worth looking at alternatives like satellite messengers or personal locator beacons, which is where this guide comes in.
Personal Locator Beacons, or PLBs, are essential tools for anyone venturing into remote or risky environments. These devices use a 406 MHz signal to communicate with search and rescue teams through a satellite connection. They work anywhere on Earth, including the poles, and can be used on both land and sea. You would typically use a PLB when other self-rescue methods have failed, such as when your VHF radio is not getting a response or your mobile phone is out of range. In such dire situations, the PLB serves as a last resort to trigger a rescue.
Unlike VHF radios that transmit horizontally and rely on land-based stations, PLBs transmit vertically to satellites, offering superior coverage. After purchasing a PLB, you need to register it. Each PLB has a unique 15-digit number that helps rescue services identify you and tailor their response. The devices also feature built-in GPS and a 121.5 MHz homing signal, making it easier for rescuers to find you more quickly.

Overview of Personal Locator Beacons (PLBs)
Personal Locator Beacons, or PLBs, are emergency devices used to send distress signals. They work on a frequency of 406 MHz and connect to search and rescue services through satellites. One key advantage is their ability to function anywhere on Earth, including remote areas like the poles.
PLBs are used when other emergency methods fail. For instance, when your VHF radio and mobile phone do not work, a PLB becomes your final option. They are effective because they transmit signals vertically to satellites, ensuring better global coverage.
When you buy a PLB, the first step is to register it with the Coast Guard. Each PLB has a unique 15-digit number that must be linked to your personal details. This helps rescue services tailor their operations to your specific situation. The registration process can be completed online.
PLBs also come with built-in GPS, speeding up the location process. They emit a 121.5 MHz homing signal, which is useful for nearby rescue aircraft and vessels to pinpoint your location.
Compared to Emergency Position Indicating Radio Beacons (EPIRBs), PLBs have a 24-hour battery life, while EPIRBs last for 48 hours. PLBs are manually activated, unlike EPIRBs which can activate automatically in water. Plus, PLBs are registered to individuals, whereas EPIRBs are linked to vessels.
If you venture into water, owning a PLB is wise. They’re essential for small boat owners, personal watercraft users, paddle boarders, kayakers, and anyone going far from shore.
Registering Personal Locator Beacons
First, get your PLB’s unique 15-digit number. You can find this on the back, side, or the box of the unit. This number is crucial as it identifies your specific beacon.
Next, go online to register your PLB with the National Oceanic and Atmospheric Administration(NOAA). During this registration, you’ll provide personal details, including, if applicable to your situation, your vessel. This information helps search and rescue services tailor their response to your circumstances.
PLBs transmit signals on 406 MHz to search and rescue via satellites, which operate globally, even at the poles. They also have built-in GPS for precise location tracking and a 121.5 MHz homing signal for rescue aircraft and vessels.
PLBs differ from EPIRBs mainly in their battery life and activation method. While PLBs can transmit for 24 hours, EPIRBs can last 48 hours and can be water-activated. PLBs are registered to individuals, while EPIRBs are tied to vessels.
