More Information

At 5.4 oz and topping just 4.5 inches, the ResQLink+ is both a small and buoyant Personal Locator Beacon. Small enough to be carried in your pocket, clipped to a backpack or stored inside an inflatable life jacket.

With three levels of integrated signal technology - GPS positioning, a powerful 406 MHz signal, and 121.5 MHz homing capability - the ResQLink+™ 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.

PLBs have been proven tried and true in some of the world's most remote locations and treacherous conditions. Just ask the 400 or so pilots, boaters and backcountry explorers who were saved by a PLB during a rigorous test program in Alaska. Based in large part on the test results, the federal government approved use of PLBs in the United States in 2003.

Even in extreme conditions and situations, the ResQLink+™ activates easily. Just deploy the antenna and press the ON button. With its powerful 66-channel GPS, the ResQLink+™ 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 ResQLink+™.

Two built-in tests allow you to routinely verify that the ResQLink+™ is functioning and ready for use - with the push of a button, you can easily test internal electronics and GPS functionality.

By AVID BOATER on March 5, 2015 It was recommended to me by fellow boaters, and some hikers I know. Of course, I can't tell you how it works because I haven't tried it, but all the reports suggest it will work very well in my area of boating, which is the coastal area of British Columbia, and Washington State. Many areas are not covered by VHF radio or Cell Towers so it can be a very lonely place on the central and northern coast at times.



If you want to be rescued!

By Spadman on January 6, 2015 As a Search & Rescue pilot in Laos I learned that extra radios and extra batteries could make the difference in a successful rescue. My ResQLink+ will be with me on every flight. There is a lot of "pine barren" land in central Virginia and this sort of rescue beacon capability is a necessity.

Piece of mind.

By Bushchick on January 6, 2015 I along with my sisters purchased this for my ageing father who works on the land alone out of mobile range. I liked that you have to put up the antenna before you can activate it otherwise he might forget.

Radio Redundancy for Coastal Cruising

By Liberty Sailor on January 6, 2015 I am planning a two month coastal cruising trip on my sailboat in the summer. Although I also have a Delorme in reach explorer that I can use for satellite communication, I am a Civil Air Patrol SAR member who knows that sometimes GPS can screw up, and nothing is more reliable than a radio beacon. This is a cheap option for someone like me who cannot afford an EPIRB, and gives me peace of mind that if I fall overboard, this will still be attached to my life jacket, and I won't have to worry about it being charged and ready, because it is always ready. Two way communication is nice when organizing a rescue, but it doesn't always work. This should always be your first method of sending an SOS, because it is the most reliable, and if you don't have a dedicated SOS beacon, then you are asking for trouble.

The purchase price is nothing when it all hits the fan!

By Baytown on January 6, 2015 A very well made and laid out unit. It's so compact, there's no reason to not take it with me when I'm either on the water in my Sea Kayak, or trudging alone in the bush. Should I ever be in the situation where I need professional assistance, then I'm able to give the SAR teams the best location data I can with this little unit. Great peace of mind.

Give me some hope

By The Ancient on June 19, 2014 I dodged the "Bullit" once and I spend a lot of time outdoors alone. I needed something that could possibly be a life saver and put me a little more at ease being outdoors. I believe the ResQLink+ PLB will do that. I hope I never have to find out!!

just bought it

By Red Bud on May 8, 2014 I waited for this to come on the market for a few years. After a lot of research I decided to visit REI to see this unit. Its small size and light weight were two big factors why I bought it. Plus I like the idea that PLB is a lot more powerful and faster to obtain help than Spot. I should be able to carry it in my backpack without a problem. My long wait is now over.

Better safe than sorry

By Candle on January 6, 2014 I recently purchased a kayak and kayaked up and down various waterways by myself and enjoying it. I did not realize that my daughter thought I was a little reckless for my age (72). She bought me this ResQLink for Christmas and I registered it dutifully. I trust I will not ever need it on these inland waterways but You'll never know if an alligator is getting to me. It is now a permanent attachment to my life jacket.

Safe with 151 gram!

By happy seal on September 12, 2013 First I preferreed the aqualink view,because it gives a confirmation of the emergencycry; because of less weight and quick Availability I bought the ResQLink+. I hope it gives me peace of mind while I am solo sailing! And I hope I never have to use it.


By DOW on July 8, 2013 After thorough research by both my son and me - youtube, websites, retail stores, friends, etc. - we agreed that while some of the bells and whistles that other products have, i.e., texting, e-mails, course charting, etc., were nice, we wanted the best in class for what was paramount - rescue in case of emergency. We both bought the ResQLink+ (floatation only cost a bit more, so why not?). Registration at NOAA on-line was a breeze, and I can't wait to strap it to my wading outfit when I go back country fly fishing day after tomorrow.

Why I Bought An ACR ResQLink (or... Why I Didn't Buy A SPOT)

By ondafringe on June 25, 2013 I've had my ACR ResQLink for about a year. No issues, thus far, but haven't had to use it in an emergency. Hopefully, I never will but, if I do, I have not doubt it will do what it's supposed to do. I am a hiker but bought the one that floats. I wrote a fairly detailed article covering the reasons I bought an ACR ResQLink and why I didn't buy a SPOT. For those who haven't made up their minds which way to go, you can read my reasoning on my blog: http://ondafringe.wordpress.com/2013/06/22/why-i-bought-a-plb-or-why-i-didnt-buy-a-spot/

Great Price for Aviation

By WingNut on June 11, 2013 VERY happy with my ACR ResQLink+ Buoyant 406 MHz PLB. It was a great price (puchased on iBoats.com). I hope to never use it for real, but I make sure to self-test every month as recommended. Also signed up for www.406Link.com and activated the Plus account. This allows me to do self tests and send out messages to myself and emergency contacts telling them the system is working.

It's small, light, bright yellow, and it floats!

By Floater on February 13, 2013 I really appreciate the design of this unit. Most importantly it is a perfect color for visibility in the water, it floats, and it has only two very simple buttons. Those buttons are cleverly hidden under a hinged cover such that they cannot be missed when you need them, but would be really hard to accidentally activate. I feel fortunate to say that I haven't needed to be rescued yet, but have every confidence that this unit will be of tremendous utility if the occasion should present itself. Thanks for making such an affordable and thoughtfully-designed product!

Staying Alive

By Asa Foley from Sacramento via REI.com on January 29, 2013 I have hiked and biked in many places that do not get cell service. I also crawled out two miles after breaking my ankle in six places, it was not fun. I am worried about getting charged for being rescued, but a choice between a big bill and death, I will work it out. This will still not take the place of a well setup pack with med kit, but it sure makes my wife feel allot safer. We also carry it often in the car when we have our five month old because getting 911 to answer is often a joke in Sacramento and in case of an accident or med emergency it will be handy to have. Bottom Line Yes, I would recommend this to a friend

I would buy this product again

By Mike from Fair Lawn, NJ via WestMarine.com on January 29, 2013 Works Great. Bottom Line Yes, I would recommend this to a friend.

ACR ResQLink+ Floating PLB, with Built-In GPS

By George Wey from Tampa, FL via Amazon.com on January 29, 2013 I would not rely on the other brands of "locator beacons" like the popular "SPOT" with does not use the standardized 406 MHz Signal. Unlike "SPOT", ACR ResQLink+ does not have all the frills, it is to be used in an emergency only so you are not killing your battery sending "text messages". "SPOT" requires a membership/annual fee so if you forget to pay your SOL! ACR ResQLink+ can be used in any country, "SPOT" is USA only. ACR ResQLink+ has 406MHz @ 5 watts, GPS, and 121 MHz Homing, 3 systems to help Search and Rescue (SAR) locate you faster then any other Personal Locator Beacon. After doing my own research, ACR ResQLink+ is the ONLY type of personal locator beacon I would depend my life on for activities in the wilderness! Update: I started diving with my PLB offshore and have been keeping it clipped to me inside an OTTER BOX 9000 with 4 ultra high 5 min Cyalume Chem Sticks and some other emergency items. In case the charter boat leaves me or I cant find them in an emergency.

ResQLink+ is a great value

By Marty from Fort Myers via Westmarine.com on January 29, 2013 It is small but has a lot of great features. Bottom Line Yes, I would recommend this to a friend


Q: How do I register my beacon?

406 MHz Beacons must be registered with the National Authority of the country you live in.

Step 1.  Visit our Registration database to find the appropriate National Authority

Step 2.  Register with your countries National Authority via Mail, Fax or for the fastest service register online.

Registration in the United States

The national authority that accepts beacon registrations in the United States is the National Oceanic and Atmospheric Administration (NOAA). Here are three easy ways to register:

1.) The fastest and easiest way to register is online at www.beaconregistration.noaa.gov .    Recommended method. Verify and validate information before submitting.

2.) Mail the registration form with the pre-addressed, postage paid envelope to:

1315 East West Hwy
Silver Spring, MD 20910

Please print legibly.

3.) Faxing a registration is also acceptable. Fax the registration form to the Fax number on the bottom of the registration form. To reduce the possibility of erroneous entry please verify legibility of information and validate information on form to UIN on beacon before faxing. Please print legibly and in BLACK ink.

All registration forms will be entered in the 406 MHz beacon registration database within 48 hours of receipt. The information you provide on the registration form is used for rescue purposes only.

A confirmation letter, a copy of the actual registration and a proof-of-registration decal will be mailed to you within two weeks. When you receive these documents, please check the information carefully to ensure that the information provided on the label agrees with the information on the beacon and then affix the decal to your beacon in the area marked "BEACON DECAL HERE." If you do not receive confirmation from NOAA in the expected timeframe, or if the information on the label is incorrect call toll free 1-888-212-7283 for assistance.

Registration outside of the United States

In countries other than the United States, 406 MHz beacons are registered with that country's national authority at the time of purchase. The sales agent should have assisted you in filling out the forms and sending them to the country's national authority. Alternatively, visit our Registration database or many countries allow online registration in the International 406MHz Beacon Registration Database (IBRD) at www.406registration.com.

To verify that the unit is properly programmed for your country, view the UIN label on the back of the unit. In the event that the beacon is not programmed for your country, the sales agent (if properly equipped) can reprogram the unit for the correct country.

Q: What are my obligations with regard to registering and re-registering my beacon?

A beacon should be registered at the time of purchase or installation. The registration of a beacon is valid for 2 (two) years. The owner should re-register the beacon every two years.  If change of ownership occurs, the original owner must notify the authorities and de-register the beacon before the new owner can register.

Q: Why is it so important for me to register my beacon?

Registering the EPIRB, ELT or Personal Locator Beacon is required by law in the United States and 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.

Q: I tried to register my beacon but the authorities tell me that it needs a different ID number programmed in. Do I need to send this back to you?

This can be done by any Certified Battery/Service Center.  Please have your registration form and beacon available when contacting a Certified Battery Replacement Center for assistance.

Q: Where do I take/send my unit for battery service?

Visit our Battery / Service Locator. Contact the battery/service station for instructions on how to send the beacon to them. Please contact the BRC for the cost for this service.


Q: How do I know when the battery is due for replacement?

There is a battery expiration date label on every beacon.

Example Image: Battery Replacement Date is 07/2010


Q: Can I buy a battery from you and replace it myself?

No. The battery cannot be purchased. This is a life saving device and you need to have the tools, hardware and software to perform a battery replacement. Full functional testing is done on the unit, after the battery is replaced, to make sure that the unit will last another 5 years in the field.  The battery of any EPIRB, ELT or Personal Locator Beacon needs to be replaced by an ACR/Artex Certified Battery Replacement Center (BRC), where trained technicians will perform this service.

Q: What will happen if I do not replace the battery every five years?

The chances of surviving a life threatening situation is greatly diminished if proper care and maintenance is not given to a beacon.

Q: Do I have to replace the battery if the beacon goes off by mistake and why?

Yes, as this is a lifesaving device it should be diligently maintained to perform as specified. For this unit to transmit for the full 24 hours it will need a new battery as any inadvertent activation will deplete the existing battery.

Q: Where do I dispose of a beacon battery?

For information about disposal of lithium batteries or products with lithium batteries in them, please contact your local waste management company.

Q: Is there any special instruction for shipping a battery or a unit with the battery in it?

There may be, depending on the beacon that you have. Due to transportation regulations changes, some ACR & Artex products that contain lithium batteries may need to be shipped as Hazmat. Please visit the product page for your product and review the download tab for the Material Safety Data Sheets (MSDS).

Q: Is there a local service center where I can get my beacon serviced?

Find a battery/service center here.

Q: How do I know the beacon is working?

Perform a monthly self-test. If the test passes, the beacon is working. If self- test does not pass, take/send the beacon in for service.  If you want to know that your beacon signal is reaching the satellite system and your signal is being received back down to earth please check out our advanced testing service called 406Link.com.

Q: How often should I carry out a Self Test?

The beacon owners' manual usually recommends the frequency of these tests; typical advice is once a month and/or before extended trips.  

Advanced Satellite Testing can be performed using our new service called 406Link.com

Q: What is a GPS Self Test?

Newer GPS (sometimes referred to as GNSS) equipped beacons may also include an optional GPS Satellite Acquisition Self Test (not all GPS beacons have this ability), which tests the operation of the GPS Receiver and its ability to encode your location into the transmitted distress message. It is not uncommon for this test to only be permitted to be performed once or twice over the life of the battery (e.g. every couple of years), as this type of test can significantly reduce the battery life of the beacon.  For beacons installed in commercial craft there are often regulatory requirements that define how often these tests should be performed.    

GPS Testing with 406Link.com

Current ACR GlobalFix EPIRBs and older Model Personal Locator Beacons (AeroFix, TerraFix, AquaFix, MicroFix, ResQFix) have the ability to perform a GPS Test, however this GPS Test is not transmitted to the satellites, so if you have an account with 406Link.com your GPS Coordinates will not appear.

New ACR Personal Locator Beacons including the AquaLink and SARLink models can perform GPS Self Tests that will actually transmit to your GPS Coordinates to the satellites and with 406Link.com pin point your location onto a map.   These tests are limited to 12 Tests for the PLB-350B Model over the 5 year life of the battery and 60 Tests for the PLB-350C.                                    

Q: What should I do if I get a Self Test failure?

If you get a Self Test failure, first check the instructions in the user manual supplied with your Beacon, make sure you carried out the test correctly and that you have followed any instructions provided.  If you are sure your Beacon failed the self test then you should contact the beacon manufacturer or one of their appointed service agents for further advice and instructions.

Q: Are there any Beacons that I can't test Through the Satellites?

Yes, in particular some older models of Beacons do not transmit a 406 MHz burst, so they cannot be tested in this way. In addition some current other manufacturers models of Beacon incorporate features (e.g. a rolled up one time only use antenna) that reduce their radiated power output during a Self Test and therefore these beacons do  not transmit a signal that is strong enough to reach the satellites.

Learn more at 406Link.com

Q: How does the GPS Self Test feature work?

A lot of beacons on the market have the capability to do a GPS test, in which the beacon turns the GPS engine on, acquires GPS data and flashes a light to signify the test is completed.  

New Personal Locator beacon models from ACR have the ability to transmit this GPS location in a self test burst and pin point your exact location on a map using 406Link.com to ensure you that (1) your beacon is working perfectly and can reach the satellite system and (2) that your GPS is working perfectly.

Q: How many Self Tests and GPS Test can I perform?

406 MHz beacons (Manufactured in 2010 or later) can perform 420 self tests over the 5 year life of the battery. The PLB-350C (Models: AquaLink View and SARLink View) can also perform 60 GPS Self Tests over the 5 year life of the battery. The PLB-350B (Models: AquaLink and SARLink) is limited to 12 GPS Self Tests over the 5 year life of the battery.

ACR beacons (Manufactured prior to 2010) can perform 340 self tests over the 5 year life of the battery. If you have a beacon from a manufacturer other than ACR, please refer to your beacon owner's manual or contact your beacon manufacturer for the number of budgeted self tests your beacon can perform over the 5 year life of the battery.   

Learn more about advanced satellite testing through the satellite system at 406Link.com    

Q: What do PLBs do?

Personal Locator Beacons (PLBs) are distress radio beacons which transmit location information about individuals directly to Search and Rescue forces letting them know that the owner is in grave and imminent danger.

Q: Where can I purchase a beacon?

Visit our Where To Buy dealer locator

Q: Can 406 MHz beacons be used anywhere in the world?

Yes, 406 MHz beacons can be used anywhere in the world, including the Poles.

Q: Is there a subscription fee for beacon registration or rescue service?

Beacon registration is free, should you ever have to activate your beacon, rescue is free in most parts of the world.

Q: When do you use a Beacon?

Most Search-and-Rescue (SAR) organizations instruct that beacons are satellite signaling devices of last resort, for use when all other means of self-rescue have been exhausted, where the situation is grave with imminent danger and the loss of life, limb, eyesight or valuable property will occur without assistance.

Q: Do I need a radio license?

For the latest information, in the United States you may contact the Federal Communication Commission at toll-free 1-888-CALLFCC or visit the website of the FCC.  Outside of the United States, contact your local authority for the requirements.


Q: What is a UIN and where do I find it on the beacon so I can register my beacon?

A UIN is a Unique Identifier Number that is programmed into each beacon at the factory. The UIN number consists of 15 digit series of letters and numbers that make up the unique identity of the beacon. The UIN is on a white label on the exterior of the beacon. The UIN is also referred to as the Hex ID.


Q: Is it true that certain emergency beacons no longer work?

The 121.5MHz and 243 MHz beacons are no longer satellite detectable. The beacons may still function but the emergency satellite system will no longer detect the emergency signals from these frequencies. Please read the explanation of the phase out of the 121.5/243 MHz frequency from Cospas-Sarsat at http://www.sarsat.noaa.gov/phaseout.html.

If you have a 121.5 MHz or 243 MHz beacon, you should upgrade to a new 406 MHz beacon.

Q: Can I take my beacon with me on an aircraft?

You may wish to check with the airline about any restrictions or documentation that you may need to carry with the unit.   We suggest that you print a copy of the MSDS and bring it with you. We also recommend that you carry the Product Support Manual to explain what the unit is (MSDS sheets and Manuals can be found on the product web page).

Q: What happens if I set off a false alert by mistake?

Don't panic, as long as it was a genuine mistake and not deliberate you have nothing to worry about, however you must turn off your Beacon and contact the emergency services as quickly as possible to let them know your transmissions are a False Alert.

Deliberate misuse or not notifying the proper authority may incur a severe penalty.   When you call be prepared to provide the following information: 

The beacon Unique Identifier Number (UIN) (15 Hex ID printed on the beacon),

  1. Date
  2. Time and duration of the false alert
  3. Location of the beacon at the time of the false alert
  4. Cause of the false alert

The primary contact point in the United States for the notification of False Alerts is the United States Air Force Rescue Coordination Center (USAFRCC) the telephone number is 1-800-851-3051. However if you have an EPIRB you can contact the United States Coast Guard (USCG) in the following areas: Atlantic Ocean / Gulf of Mexico USCG Atlantic Area Command Center Tel: (757)398-6390 Pacific Ocean Area / USCG Area Command Center Tel: (510) 437-3700 USCG HQ Command Center Tel: (800) 323-7233. If you have an ELT as well as contacting the USAFRCC you might also want to contact your local Flight Service Station (FSS) on 1-800-WXBRIEF  (1-800-992-7433).    

Q: Whats the difference between the AquaLink models and the SARLink Models?

The quick answer is flotation.

The AquaLink and AquaLink View Personal Locator Beacons are buoyant so you can retrieve them should you ever accidentally drop them in the ocean, lake or in a river.

The SARLink and SARLink View Personal Locator Beacons have a slimmed down back case to make them slightly smaller but these models will not float.
