How to choose a personal locator beacon
Choosing the right personal locator beacon (PLB) is about matching its capabilities to your activities and risk profile. All PLBs on our list use the international 406 MHz frequency and the COSPAS-SARSAT satellite system, which requires no subscription and alerts search and rescue agencies globally. The first step is to legally register your beacon with the national authority; this provides rescuers with your emergency contacts and details. For more on trip planning and safety protocols, see our guide on outdoor safety.
What to look for
- Confirmation Services: Features like Return Link Service (RLS) send a message back to the beacon confirming your distress signal was received, providing critical peace of mind.
- Size and Buoyancy: If you’re a boater or angler, a buoyant design is essential. For backpackers, the smallest and lightest models minimize pack weight and bulk.
- Battery Life: PLBs have a non-replaceable battery with a multi-year shelf life and a shorter operational life once activated (e.g., 24+ hours). Check both metrics.
- Additional Alerts: Some beacons add local alert systems like AIS (for nearby boats) or 121.5 MHz homing signals to help rescuers pinpoint you on final approach.
Always follow the manufacturer’s instructions for testing, maintenance, and activation. A PLB is for life-threatening emergencies only. For broader safety resources, you can consult the U.S. Coast Guard Boating Safety site and the National Weather Service for conditions.
FAQ
Do personal locator beacons require a subscription?
No. All the personal locator beacons on our list use the international COSPAS-SARSAT satellite system, which does not require a monthly or annual subscription fee. You must, however, register the beacon with your national authority, which is a one-time process.
What’s the difference between a PLB and a satellite messenger?
A Personal Locator Beacon (PLB) is a dedicated, single-purpose device for sending a life-threatening distress signal to search and rescue authorities via satellite. Satellite messengers often allow for two-way texting, tracking, and non-emergency communication but typically require a subscription. PLBs generally have longer battery shelf lives and are built to more rugged standards.
How important is waterproofing in a PLB?
Very important. Emergencies can happen in rain, snow, or if you fall into water. Many PLBs are designed to be waterproof at significant depths. For maritime activities, a buoyant design is also a critical safety feature to keep the beacon afloat and transmitting.
Can I test my PLB?
Yes, but you must follow the manufacturer’s instructions precisely to avoid accidentally triggering a real distress signal. Most beacons have a self-test function that checks battery and GPS functionality without transmitting to satellites. Some models offer optional subscription services for sending test messages to your own contacts.
