Quick Answer
Yes, a personal locator beacon (PLB) can be used overseas, but its effectiveness depends on the satellite system it uses, such as Cospas-Sarsat, which has global coverage, or Garmin's own satellite network, which has more limited international coverage.
International Coverage and Regulations
When traveling overseas with a PLB, it’s essential to check the device’s certification and compatibility with the local emergency services. Cospas-Sarsat-certified PLBs, for example, will work in most countries, but Garmin’s devices may not be as widely recognized. Additionally, some countries, like the United States, require PLBs to be registered with the Federal Communications Commission (FCC) before use.
Satellite Systems and Accuracy
PLBs use one of two primary satellite systems: Cospas-Sarsat or Garmin’s own network. Cospas-Sarsat has a global coverage area, with 6 satellites in orbit, providing location accuracy within 5-10 kilometers (3-6 miles). Garmin’s system has a more limited coverage area, with 18 satellites, offering location accuracy within 5-10 kilometers (3-6 miles) in North America, but significantly reduced accuracy in other regions.
Activation and Notification
Activation of a PLB sends a distress signal to the nearest satellite, which then alerts local emergency services. It’s crucial to understand that PLBs are designed for life-threatening emergencies only and should not be used for recreation or non-emergency situations. Activation times can vary, but typically, emergency services receive the signal within 5-15 minutes, depending on the device and satellite system used.
