The ACR ResQLink Non-Buoyant PLB is a full-powered, GPS-enabled rescue beacon for general recreational users. Weighing just 4.6 oz and topping just 3.9 inches the lightweight ResQLink distress beacon is smaller than a mobile phone. With three levels of integrated signal technology – GPS positioning, a powerful 406 MHz signal, and 121.5 MHz homing capability – the ResQLink PLB quickly and accurately relays your position to a worldwide network of search and rescue satellites. A built-in strobe light provides visibility during night rescues. Registering your Personal Locator Beacon is required by law in most countries. Registering is very important because should your beacon ever be activated, it is how Search and Rescue Teams will know who you are, and contacts provided may be able to supply information about your specific travel plans. In the absence of this information, it may take longer for a search-and-rescue operation to begin. Should you wish to register your device in the US, please choose our ‘Programmed for US Registration’ listing. For registration outside the US please choose our ‘Programmed for Rest of World’ listing and advise us of your required country of registration after purchase so we can program the device for you. Please note that some countries, such as Spain and Germany, do not allow PLB registration unless registered to a vessel. Users in these countries without a vessel can register their devices in the US if required.
