ACR ResQLink 400 Advanced Floating PLB
The ACR ResQLink 400 is a compact, subscription-free Personal Locator Beacon (PLB) that floats, uses GPS positioning, and connects directly to the global COSPAS-SARSAT satellite rescue network for emergency response anywhere in the world.
Designed for serious marine and outdoor safety, the ResQLink 400 provides a fast, accurate distress alert without relying on mobile coverage, apps, or ongoing fees.
What Is the ACR ResQLink 400?
The ACR ResQLink 400 is a 406 MHz GPS-enabled Personal Locator Beacon with built-in buoyancy, making it suitable for boating, sailing, kayaking, fishing, tramping, and remote travel.

Registration is free and ensures rescue services have your contact details and trip information if the beacon is activated.

Using an unregistered PLB may delay rescue response.
