ACR ResQLink PLB400

The ACR ResQLink PLB400 is a compact personal locator beacon designed for military personnel, law enforcement, remote workers, and outdoor professionals who operate in isolated or high-risk environments. This single-unit emergency device provides a critical lifeline when conventional communication fails, transmitting your precise location to rescue coordination centers via satellite technology. Built to perform in the harshest conditions, the PLB400 delivers reliable distress signaling without dependency on cellular networks or line-of-sight communications.

The ResQLink PLB400 operates on 406 MHz and 121.5 MHz frequencies, establishing direct contact with search and rescue authorities through the international Cospas-Sarsat satellite system. Weighing just 1.12 lbs, this portable unit remains light enough for duty belt carry, rucksack integration, or survival kit inclusion without adding significant operational burden. The device activates via manual trigger mechanism, initiating immediate transmission of your encoded location data with integrated GPS positioning to facilitate rapid rescue response in emergency situations.

Tactical teams, wilderness rescue personnel, and military special operations units benefit most from the PLB400's combination of portability and performance reliability. Law enforcement aviation units and remote field operations teams integrate this beacon as standard emergency equipment, ensuring personnel accountability in high-altitude, ocean, or remote terrain deployments. The device requires minimal training and no external power sources beyond its self-contained battery, making it compatible with any duty uniform, pack configuration, or tactical loadout without compatibility concerns.
