Quick Answer
A PLB (Personal Locator Beacon) and a satellite phone serve different purposes and are not mutually exclusive. While a satellite phone can send messages, a PLB sends an emergency distress signal to emergency responders in case of a life-threatening situation. You may still consider a PLB as a redundant safety measure.
What is a PLB and How Does it Work?
A PLB is a small device that sends a distress signal to emergency responders in the event of a life-threatening situation. It operates on a different frequency than a satellite phone and can be activated without needing to call or send a message, making it easier to deploy in emergency situations. PLBs typically use the 406 MHz frequency, which is monitored by satellites and emergency response centers.
When to Use a PLB vs. a Satellite Phone
A PLB is designed for emergency situations where every minute counts, such as in the event of a crash, fire, or medical emergency. In contrast, a satellite phone is better suited for sending messages, making calls, and checking in with loved ones. If you’re planning a remote expedition or adventure, consider carrying both a PLB and a satellite phone for maximum safety. This way, you can use the PLB in an emergency and the satellite phone for non-emergency communication.
Choosing a PLB and Satellite Phone Combination
When selecting a PLB, look for devices that meet international standards, such as the COSPAS-SARSAT protocol, and have a built-in 121.5 MHz homing device. For a satellite phone, consider devices that offer global coverage, such as the Iridium 9555 or the Garmin inReach Explorer+. Make sure to research and purchase devices from reputable manufacturers and follow the manufacturer’s guidelines for use and maintenance.
