Personal GPS Trackers and Satellite Communicators

Standard 4G personal alarms may not be enough for lone workers in remote areas. That’s where Personal Locator Beacons (PLBs) and satellite communicators come in. These devices let you send an SOS alert from anywhere — even where mobile coverage doesn’t exist.

PLBs like the Garmin inReach Mini 2 and Satellite communicators like the ZOLEO, Spot Gen4, and Spot X use global satellite networks like Iridium or Globalstar. These systems require a satellite subscription and provide reliable, direct-to-rescue alerting or custom messaging in critical situations.

Working closer to town or within 4G coverage? You might not need a satellite device. Read our guide to personal alarms in 2025 to decide which solution best fits your situation.
