A Personal Locator Beacon (PLB) is a small, portable device that helps individuals signal for help in emergencies. When activated, it transmits a distress signal to search and rescue services via satellite, providing your location. PLBs are commonly used by outdoor enthusiasts, such as hikers and boaters, who may find themselves in remote areas. PLBs operate on a specific frequency and are designed to work globally. They are battery-powered and can be activated manually, making them reliable in situations where other communication methods may fail. Many PLBs also have a built-in GPS feature, enhancing their accuracy in locating the user.
