Important: Register Your Beacon Before You Head Out
This is a 406 MHz emergency beacon. U.S. federal regulations require it to be registered with NOAA before use — and it is free.
Register online at beaconregistration.noaa.gov (fastest method). Registration links your beacon's unique ID to you, your vessel, and your emergency contacts, so the Coast Guard and search-and-rescue teams can respond faster if it is ever activated.
Registration is the owner's responsibility.
The ACR ResQLink 400 is a compact, buoyant Personal Locator Beacon built to survive harsh conditions on land, sea, or in the air — no subscription required. Three integrated signal layers work together: a 406 MHz distress signal, GPS and Galileo GNSS positioning, and a 121.5 MHz homing frequency, relaying your location to a global network of search-and-rescue satellites. A digital display shows live status and GPS coordinates, while a built-in visible strobe and infrared strobe support low-visibility and nighttime rescues. Deployment is straightforward — extend the antenna and press the button — and the beacon guides rescuers to within 100 meters or less of your position. The included multifunction clip system offers flexible attachment options for different activities and gear configurations.
