The ACR Electronics ResQLink 400 (Model 2921) is a compact, buoyant Personal Locator Beacon (PLB) engineered to perform in the most demanding conditions — on land, at sea, or in the air. Professionally built and tested to military-grade durability standards, this PLB requires no subscription and delivers true global coverage through the Cospas-Sarsat satellite network, including the advanced MEOSAR system.
The ResQLink 400 employs three integrated layers of signal technology: a powerful 406 MHz distress signal, 121.5 MHz homing capability, and a dual-constellation GPS/Galileo GNSS receiver. Once activated, the beacon can guide rescuers to within 100 meters of your position — 95% of the time, within 5 minutes of the distress signal being transmitted. Activation is simple: deploy the antenna, press the ON button, and the unit does the rest.
