Personal Locator Beacons
Personal Locator Beacons (PLBs) are small, portable devices designed to transmit a distress signal to search and rescue authorities in the event of an emergency. They operate on a frequency monitored by satellite systems, allowing rescuers to pinpoint the location of the beacon. PLBs are commonly used by hikers, boaters, and pilots, as well as individuals working in remote locations. They are an essential tool for anyone traveling in areas where cell phone coverage is unreliable or non-existent. PLBs are designed to withstand extreme temperatures, shock, and water immersion, making them suitable for use in harsh environments. They typically have a battery life of several years and can be manually activated or set to automatically activate in the event of an emergency.
