ResQLink 400 Personal Locator Beacon

When you are operating in “dead zones” where cell towers and even satellite messengers might struggle, the ACR Electronics ResQLink 400 is the ultimate high-authority fail-safe. Unlike subscription-based devices that rely on private satellite constellations, this is a dedicated Personal Locator Beacon (PLB) that taps directly into the Cospas-Sarsat global search-and-rescue satellite system. It is a “zero-compromise” tool designed for one specific mission: getting you home when everything else fails.

What makes this device so trustworthy is its professional-grade reliability. It requires no monthly subscription and is engineered to function in the most extreme conditions. When you deploy the antenna and press the button, you are initiating a direct, high-powered distress signal that is monitored by government agencies worldwide. It is the “Hardwired Emergency Line” of the endurance world.

Why it’s a critical “Last Resort” layer for your safety protocol:

• Triple-Signal Redundancy: The ResQLink 400 utilizes three levels of integrated signal technology—GPS positioning, a powerful 406 MHz distress signal, and a 121.5 MHz homing capability—to lead rescuers directly to your location with meter-level precision.
• Survival-Focused Engineering: It is buoyant, waterproof, and features a built-in LED strobe and infrared strobe to ensure you can be spotted from the air or ground, even in total darkness or heavy cover.
• Long-Term Readiness: With a 5-year battery life and an easy-to-run self-test system, this is a “set it and forget it” piece of gear that lives in your pack, providing the ultimate peace of mind for solo mountain missions or remote trail runs.
