You don't need a monthly or annual subscription to use ACR's ResQLink+ Personal Locator Beacon, but if you decide to activate this tiny floating PLB, you better make damn sure you're in need of a search and rescue. Middle-of-the-ocean or deserted-island lost in a boat or plane. Medical emergency. Being held captive by the Kraken.
ACR sells its pocket-sized, flip-phone-looking GPS-enabled rescue beacon for "situations of grave and imminent danger to life" only. Boaters, pilots, and water sportsmen can keep the devices in their gear kits, or on their person, over the long term with little disruption to their activity. The beacons weigh just 5.4 ounces and their longest side measures 4-1/2".
The ResQLink+ has 3 levels of integrated signal technology: GPS positioning; a 406 MHz signal; and a 121.5 MHz homing capability. When activated the beacon relays your position to a worldwide network of search and rescue satellites and, with a 66-channel GPS, guides responders to within 100 meters or less of your position. Within the continental US this alert and location pinpointing can happen in as little as 5 minutes.
The locator beacon also has a built-in strobe light.
ResQLinks are shipped with non-hazmat batteries, with a 6-year certified life, and typical shelf life of 11.
