Meet the ACR ResQLink PLB400 — a buoyant personal locator beacon designed for elite safety in any environment. Compact, rugged, and subscription-free, it’s built to keep you protected whether you’re exploring remote peaks, crossing open water, or flying above the clouds.
The ResQLink 400 leverages multi‑constellation precision and military‑grade durability to put rescue within reach. With GPS positioning, a powerful 406 MHz distress signal, and 121.5 MHz homing, it relays your location quickly to a worldwide search and rescue network. It’s also MEOSAR compatible, ensuring faster alerts and greater mission success in complex environments. For nighttime or low-visibility rescues, a built-in strobe and infrared strobe help rescuers locate you with ease.
