Personal Locator Beacon

Model Number: PLB-350B / Part Number: 2882

Head offshore with confidence. With three levels of integrated signal technology; GPS positioning, a powerful 406 MHz signal and 121.5 MHz homing capability; the AquaLink™ quickly and accurately relays your position to a worldwide network of Search and Rescue satellites, reducing search time and increasing your chances of survival. It's reliable signaling technology that has saved more than 28,000 lives since 1982.

More Information

The AquaLink™ broadcasts a unique registered distress signal that not only tells rescuers where you are, but who you are. The onboard GPS can fix your position to within 100 meters and then utilizes a powerful 406 MHz signal to relay your distress call to orbiting satellites. As local Search and Rescue is deployed, a separate homing signal and integrated LED strobe light guide rescuers to your exact location.

Learn How A Rescue Works 

The AquaLink™ is small enough to be easily carried in a pack or pocket or can be worn on deck, at the helm, in quarters or on a life vest and will float if accidentally dropped overboard. Performing a full functional self-test of the PLB's internal circuitry, battery voltage & power and 406 MHz transmission gives you the peace of mind knowing your PLB will work the moment you need it the most. ACR Exclusive: Built-in GPS acquisition test mode allows you to test GPS functionality up to 12 times over the life of the battery.

AquaLink 406MHz Personal Locator Beacon

By DS on December 27, 2016 After serving many years as an RCC technician, I thought it was only appropriate to have a PLB in my own outdoor go gear pack. I enjoy deep-water fishing and back country snowmobiling. Working rescues I had seen many times how a PLB, ELT or EPIRB saves lives. My personal experience with the 406mhz COPASS/SARSAT signal is that it's a "clean" (uncluttered) signal to the satellites that provides reliable accuracy, and when you add GPS to the unit the accuracy only gets better for your rescue team to find you in a timely manner. The 121.5 VHF homing feature allows the rescue team to listen for the VHF chirp signal. As you can imagine the louder (stronger signal) the chirp the closer the rescue team is to your position. The 121.5 VHF also allows others that are monitoring the VHF frequency (airplanes, ships, etc) in your distressed area to hear the emergency chirp signal and can possibly respond to your position to assist the rescue. The AqualLink is three tools in one. 406,mhz, GPS, 121.5VHF. It was the right tool for my needs. The self-test feature was also important to me to know the system is working properly before planning the next adventure.

Great gift for avid boaters/fishermen!

By GatorForester on August 26, 2016 My folks actually bought me the AquaLink as a birthday gift. What a great gift! My husband and I, along with our 2 young daughters, frequently head out of Beaufort Inlet at Morehead City to chase fish. We've got every piece of safety equipment necessary, but the addition of this PLB definitely adds peace of mind that if anything ever happened, the Coast Guard could find us quickly. It was easy to register and easy to learn how to use if necessary. It's now become part of our routine every time we board the boat.

PLB 350B

By pbishark on April 25, 2016 We Fish and dive offshore between Florida and the Bahammas all the time . Our boat is now fully geared and ready for the worst case scenario. Peace of mind .

Aqualink PLB

By JCP on June 15, 2015 Gives me assurance knowing I have an extra layer of security on the water. I often take my friends and family fishing/boating and you can never be too safe with the people you love.

AqualLink PLB

By Mac on June 5, 2015 This is our second ACR. We have the GlobalFix as well. We fish 100+ miles offshore and wanted the operator of the vessel to have a PLB attached to him at all times especially during night time operation. The unit is perfectly sized and the GPS feature is a must. The belt clip is handy as well but use the lanyard supplied to attach to your belt or otherwise on your person. The PLB released from the belt clip during difficult seas but the landyard kept it on my person as it was secured to my belt. Hopefully, we'll never need to activate either of these products. We trust ACR as their products are of high quality, easy to get batteries replaced and the units serviced.

Excellent product

By Tim on December 12, 2014 I love having this in my bag just in case. I'm glad I found one with a long lasting battery and not oversized.

Feeling confident

By Renegade on May 29, 2014 Researched many different PLBs and felt that this one would meet all my needs. I'm a solo boater and spend a lot of time on large bodies of water, including the Pacific Ocean, and with my AquaLink close at hand I'll be a bit more relaxed venturing out.

Peace of mind

By Bill on June 5, 2013 Has it all. Compact and easy to use. Hope I never need to activate it but peace of mind is a good thing.

Great Value and Piece of Mind

By Leisure Pools Ohio from Columbus via Westmarine.com on August 26, 2011 The ACR slogan says it all. This is my BEST last Chance. I fell absolutely safe having my epirb with me when i go off shore. Thanks West Marine.

Easy to set up and use

By Rodmastet from Michigan via Westmarine.com on August 26, 2011 Use for boating and travel

This Beacon put our minds to ease

By Hunter's Wife in Texas via Westmarine.com on August 26, 2011 I bought this for my husband on his Feb/2011 birthday. I picked this one because it had the best features and the price was good too. Watch the video on u-tube; there is a guy who demonstrates taking it from his belt clip and opening it with one hand; He made it look so easy and you get a good view of it's size. We look forward to putting this to use over the next several years. Now we don't have to worry so much. Fishing trips offshore are 40 minutes out; we end up watching the sunset on the way back quite often; once you clean the boat, clean the fish and get on the road back home it's late. How often does your husband remember to call home as soon as he and his buddies dock, especially with so much to do on their minds.

I purchased this PLB for my work in search and rescue

By From Sportys.com on July 6, 2011 Pros: Small enough to fit in a flight suit pocket. registration was easy. just go to the website and fill it all in. It looks very durable. I did not rate reliability and durability because I don't have a baseline. I sure hope that it is reliable. I will really need it if I actually need it. Cons: While it is supposed to float, I don't think that it will float with the GPS antenna facing up. If I am in the water, I will need to remember to get the GPS reciever clear of the water. The transmitting antenna will definitly clear the water if it is floating. General Comments: I purchased this PLB for my work in search and rescue. Since I operate my airplane at low altitudes having a quick and easy PLB with GPS built in was imperitive. It is now carried in my Flight bag and will be put in one of my flight suit pockets when ever I am on a mission. It is small enough to fit nicely in a pocket.

Must have, if the situation heads south

By Steve C from Detroit via Overtons.com on July 6, 2011 We do most of our boating on the great lakes, and its connecting rives and lakes. This is a must have, if the situation heads south.

High quailty products

By Sixpacked from Florida via BassProShops.com on July 6, 2011 I went with ACR for the reputation of high quailty products. A small price to pay to save your life.

Compact and powerful

By Hank from Guam via Westmarine.com on July 6, 2011 Compact and powerful. Clips on securely or fits in my vest pocket. I won't ever be without it when I'm out on the ocean.

Best for functionality and longest battery life

By SunSeeker from The Bahamas via Westmarine.com on July 6, 2011 We reviewed several PLBs and decided the AquaLink 406 GPS was the best for functionality and longest battery life. We cruise in the Caribbean and will take it on road trips throughout the US.


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.

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: 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: 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: 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.
