The ACR PLB ResQLink+ 375 is a full-powered, GPS-enabled rescue beacon that quickly and accurately relays your position to a worldwide network of search and rescue satellites - ideal for sailors, anglers, pilots and general recreational users. 

ACR PLBs have been proven, tried and tested in some of the world's most remote locations and treacherous conditions. Even in extreme conditions and situations, the ACR ResQLink+ 375 PLB activates easily.

ACR ResQLink+ Key Features:


The ResQlink+ is an inherently buoyant PLB and is smaller than a mobile phone. 


This ACR PLB is manually activated by unclipping the antenna latch and moving the antenna to the upright position, before pressing the ON/OFF button for 1 second. Once activated, the ResQlink+ has 3 levels of integrated signal technology to transmit your signal via different frequencies (GPS positioning, a powerful 406 MHz signal, and 121.5 MHz homing capability).  

The powerful 66-channel GPS, the ACR ResQLink+ PLB guides rescuers to within 100 meters or less of your position. And, in the continental U.S., search and rescue personnel are typically alerted of your position in as little as five minutes with a GPS-enabled PLB such as the ACR ResQLink+.

Strobe Light

The ResQlink+ Strobe light will flash when the PLB has been activated, which increases visibility during night rescues

Batteries and Charging

This ACR PLB operates with class 2 (non-hazmat) lithium batteries, which must be replaced every 5 years. Once the PLB has been activated the battery will typically exceeds 24 hours transmitting a GPS signal.

Once you have activated your PLB, simply submit your story to ACR and send your used beacon back to them so they can have it mounted on their Wall of Fame and they'll send you a brand new beacon of equal or greater value. Find out more


It is necessary to self-test your ACR PLB to ensure that the beacon functions correctly. The ResQlink+ offers two built-in test functions to allow you to routinely verify that the ACR ResQLink+ 375 PLB is functioning and ready for use - with the push of a button, you can easily test internal electronics and GPS tracker functionality.

Subscription Free

Unlike most satellite enabled notification devices, the ACR ResQLink+ 375 PLB requires no monthly or annual subscription, making it one of the most cost effective GPS enabled emergency beacons available for long term use. In the unfortunate event of needing to use your personal locator beacon, ACR will replace it, free of charge.

Register your ResQlink+ PLB

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.

All Personal Locator Beacons sold by GTC are pre-programmed with the UK country code. Whilst they will function anywhere around the world, the first authority to be contacted in an emergency situation would be the UK Coastguard Agency in Falmouth with whom the PLB would be registered. Please contact us if you wish to have your PLB shipped with configuration for use in a country other than UK.

This ACR PLB should only be used in situations of grave and imminent danger to life. False alerts endanger lives and cause expensive disruption to Search & Rescue services. Deliberate misuse of the device could result in a penalty.

Please note that PLBs will not work underwater and should be used in a canister if you intend to carry at a depth exceeding the maximum depth stated in the technical specification.
