Emergency Position Indicating Radio Beacon (EPIRB)

Model Number: RLB-41 / Part Number 2830 & 2831

Drastically increase your probability of survival at sea with the multiple built-in redundancies of the GlobalFIX™ V4 marine distress EPIRB. Upon activation, the GlobalFIX™ V4’s robust internal GPS accurately fixes your exact location. Your coordinates are then broadcast via a powerful 406 MHz distress signal to Search and Rescue forces worldwide. In the absence of GPS data, orbiting Cospas-Sarsat satellites can accurately triangulate your position using the 406 MHz signal alone. A 121.5 MHz homing signal further guides searchers to your exact position.


More Information

The GlobalFIX™ V4 is a full-featured EPIRB loaded with high-efficiency electronics for performance you can count on, including an internal 66 channel GPS for faster acquisition from a cold start. A protective keypad cover helps prevent false activation, and the all-new, user-replaceable battery pack has a 10-year replacement interval — reducing the overall ownership cost and making replacement a breeze.

The GlobalFIX™ V4 has two functional self-tests to monitor the beacon’s transmission, power and battery performance and GPS acquisition. Pair these tests with ACR’s 406Link.com optional testing portal (available for the Americas only) and receive satellite confirmation messages directly to your cell phone or email.

A Must Have

By Jim on June 12, 2018 Great product to have on board. Hope i never use it.

Just bought

By Tmcc on June 12, 2018 Easy registration and ready for use.


By John on June 12, 2018 I purchased this product because I will be fishing out in the ocean, and wanted to get something that would help me in a situation where I may need to be rescued?.

EPIRB boating safety

By Stairway to heaven on June 12, 2018 Bracket for epirb appears solid, Epirb is something I hope to never use but it may save our life if we ever need it. Very inexpensive insurance


By STEVE on June 12, 2018 Easy to use product to be used on law enforcement boat


By Vino on May 9, 2018 Great product

Better Safe than sorry

By Capt Chris on March 14, 2018 As an avid offshore angler off the Carolina's running 60+ miles one way you cannot leave the dock without having an EPIRB. ACR is a proven product and is easy to use. Wouldn't leave the dock without one.

A must have product

By Reel Business on October 26, 2017 I frequently fish offshore single handed. I wear a life vest and am clipped into an engine cutoff should I go overboard in rough seas, but if something more serious happens VHF might not reach help and a cell phone is useless. What is your life worth in an emergency? Its a no-brainer to have a reliable EPIRB just in case.



Bering Sea

By Brianunak on October 26, 2017 A life long resident and fish on the Bering Sea, it is a no brainer to purchase this or similar product.

EPIRB Upgrade

By WAYERB on October 26, 2017 I chose the V4 for its 10 yr battery life and the fact that it is user replaceable. I occasionally fish offshore and consider an EPIRB essential survival equipment.

Offshore Cruiser

By Forever Freedom on October 26, 2017 Replacing a 10-year old EPIRB after 2 services. The user replace-able battery is a no-brianer. Within 5 years you will see all EPIRB doing the same.

$150.00 Replacement Battery

By Tom on October 26, 2017 It's great that the battery is replaceable by the owner. At $150.00 for the new battery (P/N 1104), I had to drop one star in the rating. The EPIRB itself is a well designed unit with some good features.

EPIRB Regulations

By Hook on October 26, 2017 Needed to get EPIRB for commercial fishing, best option on price and quality! £200 cheaper than the rest too! Does the job perfectly, and it comes complete! No need to buy the bracket etc seperately. Excellent value for money. Would Recommend, Here's hoping it isn't needed but its there now, very reassuring!

Long Range Cruiser

By afterburner on October 26, 2017 Bought this for trips where I go offshore out of sight of land. I have a coastal cruiser (Mainship), but occasionally have to make long crossings and needed more than my PLB in my ditch bag. I picked this particular EPIRB because of the 10 year battery life and user replaceable batteries to keep my cost of ownership down.

Solo fisherman

By johnny cat on October 26, 2017 As I often go fishing by myself, the ACR EPIRB gives me added peace of mind should the unexpected happen. In the interest of survival, I would certainly recommend this product to other boaters.


By cruiser on October 26, 2017 needed to replace my previous ACR EPIRB and this one has a 10 year battery life which is user replaceable which makes the running costs very competitive.

EPIRB Upgrade - A very simple decision

By 31415926 on October 26, 2017 Around £200 every 5 years to service the antique EPIRB that came with the boat or £279 for new ACR with GPS and 10 year user replaceable battery. A very simple decision to go for the ACR. It also has a bulkhead mount so it can be placed in an easy to grab location (unlike the old one which was in a box that was buried under various other emergency gear). I just hope I don't actually have to put it to the test of how well it works, but it is reassuring to have it there.

NEW EPIRB with GPs and long battery life which is also user changeable

By Rod on October 26, 2017 I needed to change my EPIRB as the old one was due another battery change and as it had to returned for this and the charge was substantial. This one seems to offer a better way to have the EPIRB on board at a lower cost. We do some long distant trips , like UK to the Azores so I am delighted to get this product.

First Time EPIRB Buyer - ACR made it easy

By Brad on October 26, 2017 Years of fishing knowing that if an emergency happens i may be in trouble. My kids are fishing with me now and it was simply time to take the precaution. Researched numerous EPIRB options and purchased the V4 2831 after discussing with ACR representative. They quickly explained the features and the overall cost of ownership/maintenance is reasonable Now i have the piece of mind that I can get help if needed. Registering with NOAA took only minutes online and it was easy to register for warranty purposes on the ACR site. Hope i never need to use it!


Q: What do EPIRBs do?

Emergency Position Indicating Radio Beacons (EPIRBs) are distress radio beacons which transmit location information about ships directly to Search and Rescue forces letting them know that the owner is in grave and imminent danger.  Learn How A Rescue Works

Q: Where can I purchase a beacon?

Visit our Where To Buy dealer locator

Q: Will 406 MHz beacons work anywhere in the world?

Yes, 406 MHz beacons can be used anywhere in the world, including at both poles, just remember that you need a clear view of the sky (they will not work in buildings or caves, etc.)

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: What is the difference between a Category I and a Category II EPIRB?

The difference is in how the EPIRB is deployed. 

A Category I beacon automatically deploys when a vessel sinks. The beacon floats free at a depth of 1.5 to 3.0m (4.9 to 13.1ft). The EPIRB can be manually activated while in its bracket or manually removed and activated. 

A Category II beacon is manually deployed. The EPIRB will automatically activate when removed from its bracket and comes in contact with water, or when it is still in its bracket but a person has lifted the switch to the activation position.

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: 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: 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: The date on my HydroFix™ Release Unit is not marked. What do I do?

The HydroFix™ should be marked by the owner at the time of installation with an indelible ink pen. The HydroFix™ Release Unit is good three years from the date of manufacture (which is imprinted on the bottom of the HydroFix?) or 2 years from the date of installation.

See the example below:  MFG.0611 means the HRU was made June (06) of 2011.  Thus this unit will need to be replaced 2 years from the date installed or in June of 2014.


Q: How does one take care of a beacon?

Taking care of a beacon is quick and easy. Routine maintenance is part of having the beacon ready at all times.  Follow the maintenance recommendations in the Owner's Manual.

Q: Can I use my 406 MHz beacon anywhere in the world?

You should check the local regulations of any place you plan to visit with your beacon, some countries require you to have a radio licence and a few countries have restrictions on the use of beacons, however if it's a real emergency you should always activate your beacon

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.
