Choosing Between Satellite Communicators and Personal Locator Beacons

For those venturing into remote areas, being prepared for emergencies is essential. When mobile networks are unavailable, satellite devices such as satellite communicators and personal locator beacons (PLBs) provide a means of contacting help. Understanding their differences can help users determine which option suits their needs.

Satellite Communicators

Satellite communicators, like Garmin’s inReach® Mini 2 and inReach® Messenger Plus, are designed to offer reliable two-way communication beyond the reach of cellular networks. Compact and durable, these devices allow users to send and receive messages, share their GPS location, and access weather forecasts. They also feature an SOS button, which connects users to Garmin ResponseSM, a global emergency coordination centre available 24/7.

Unlike PLBs, satellite communicators require an active subscription to connect to satellite networks. These devices can store emergency contacts, trip itineraries, and medical details, ensuring vital information is readily available in a crisis. With Garmin inReach devices, users can track their location and send updates to loved ones in real-time. Additionally, features such as extended battery life, safety charging for depleted phones, and resistance to harsh conditions make them suitable for rugged outdoor use.

The inReach Messenger Plus offers advanced capabilities, including the ability to exchange photos, voice messages, and detailed text messages when paired with a smartphone.

Personal Locator Beacons

Personal locator beacons are single-purpose devices designed to send an SOS signal in emergencies. When activated, a PLB transmits a distress signal to satellites, which then notify search and rescue authorities. Unlike satellite communicators, PLBs do not require a subscription, and their batteries typically last for years.

PLBs do not offer two-way communication, so users cannot confirm whether their distress signal has been received or share additional details about their situation. Some PLBs with Return Link Service (RLS) provide an acknowledgement that the SOS signal was received, but this does not confirm that a rescue mission is underway.

All PLBs must be registered with a government organisation, such as NOAA in the United States or Cospas-Sarsat internationally. These registrations enable authorities to contact the user or their emergency contacts to gather additional information during a rescue.

Key Differences

The primary distinction between satellite communicators and PLBs lies in their communication capabilities. PLBs only transmit distress signals, while satellite communicators provide two-way messaging, enabling users to share updates and receive responses. This feature allows search and rescue teams to prioritise and tailor their response, ensuring a more efficient rescue operation.

Satellite communicators also offer location tracking, weather updates, and messaging with loved ones, making them a more versatile choice for adventurers seeking additional peace of mind. However, these benefits come with the ongoing cost of a subscription.

Conclusion

For those who prioritise versatility and the ability to communicate during emergencies, satellite communicators provide a comprehensive solution. On the other hand, PLBs are a reliable, no-subscription option for users seeking a basic emergency signal device. The choice ultimately depends on the user’s specific needs and the level of functionality required for their activities in remote areas.
