Jotron Tron SA20 PLB

The Jotron Tron SA20 PLB is a compact personal locator beacon designed for users who need a dependable emergency alert device in remote, offshore, and isolated environments. Built around the globally recognised Cospas-Sarsat rescue network, the SA20 provides worldwide distress alert coverage using both 406 MHz and 121.5 MHz emergency frequencies, helping search and rescue teams quickly identify and locate the user during an emergency.

Designed for both maritime and land-based use, the Tron SA20 combines a rugged construction with a lightweight, pocket-friendly form factor, making it suitable for hiking, offshore work, sailing, expeditions, remote travel, and lone worker applications. Despite its compact size, the beacon includes advanced safety technologies typically found in larger emergency devices, including multi-GNSS positioning support for GPS, Galileo, and GLONASS satellite systems, helping improve location accuracy and reducing rescue response times.

One of the standout features of the Tron SA20 is Return Link Service (RLS). This technology provides confirmation that your distress alert has been successfully received by the rescue coordination centre and that your location has been identified. This additional feedback offers reassurance in emergency situations where users may otherwise have no indication that help is on the way.

The SA20 also features integrated NFC connectivity, allowing users to check device status, battery information, and programming details directly from a compatible smartphone using the companion mobile app. This makes regular device checks and maintenance simpler before heading into the field.

With an 11-year battery lifetime and more than 24 hours of operational transmission time once activated, the Tron SA20 is built for long-term reliability and emergency readiness. Additional features such as LED and IR-LED flash signalling, one-handed activation, and water resistance further enhance its suitability for harsh outdoor and marine conditions.

Compact, feature-rich, and engineered for critical situations, the Jotron Tron SA20 PLB is an advanced personal safety beacon for users who require reliable emergency communication without ongoing subscription fees.
