The ResQLink 400 Personal Locator Beacon (PLB) is engineered and tested to withstand even the harshest elements. This Personal Locator Beacon requires no subscription to use and enhances safety in a variety of environments.This lightweight and compact PLB uses GPS positioning, a powerful 406 MHz transmitter, and a 121.5 MHz homing signal to quickly and accurately relay its GPS position to the worldwide network of search and rescue satellites — narrowing the search area to less than 100 meters. In addition to being easy-to-use, the ResQLink includes a built-in strobe light and an infrared strobe to facilitate nighttime or low visibility rescue operations. The innovative design combines multifunction clips with the ResQLink 400 to provide a multitude of wearable options for a diverse range of activities.
