Which Epirb Should I Buy 2021
The early beacons used a radio frequency of 121.500-MHz , which was initially intended for downed aircraft. We have since moved over to 406MHz which is a radio signal readily detectable by satellites.

An Emergency Position Indicating Radio Beacon, commonly known as an EPIRB, is used to send an alert to emergency services. This is done either by manually activating it, or it will do this automatically when it comes into contact with water for a given period of time. After activation, a distress message, which includes a UIN (Unique Identification Number) also known at the HEX ID as the number is encoded in hexadecimal, is sent via satellite on the 406 MHZ distress frequency. The receiving satellite calculates the position of the transmitter using the Doppler Shift and then passes the details on to the appropriate mission co-ordination center.
In most countries an EPIRB is required on all commercial boats, however they are also commonly used on recreational and cruising yachts, especially those who plan to sail offshore. Which device you choose should reflect your planned cruising grounds and to some degree your approach to risk.
While EPIRBs are for boats, PLBs are for personal use. PLBs are smaller than EPIRBs and when activated have a shorter battery life. Like EPIRBs, they operate on the 406 MHz and 121.5 MHz frequencies and provide the same worldwide coverage. They also require registration to a government database; but rather than being registered to a boat, they are registered to a person, which gives you the ability to take your EPIRB from boat to boat or wherever you wish. Unlike EPIRBs, in addition to marine use, they can legally be used on land by hikers, climbers, hunters, and other adventurers. Many PLBs have a built-in strobe light, but this is not required as with EPIRBs. They are also not required to float. Once activated, PLBs such as the ResQLink 400 and the ResQLink View by ACR Electronics, have a 28 hour battery life, which is less than the 48 hours of EPIRBs. Having a PLB is great insurance while exploring away from the mother ship in your dinghy and they are a less-bulky EPIRB alternative for any small boat.
While EPIRBs and PLBs give you the ability call for rescue via the Cospas-Sarsat emergency network from anywhere in the world, they fall short in crew overboard situations where an immediate response is required. This is why in addition to having an EPIRB or a PLB you should also consider having a PAB (Personal AIS Beacon). These devices are intended to be attached to your life vest and activated if you go overboard. They use both GPS and AIS (Automatic Identification System) technology to send structured alert messages containing your precise location to any AIS receiver onboard your vessel and to other AIS-equipped boats or ships that happen to be within a typical four-mile radius. In a crew overboard situation, chances of finding and recovering the victim are greatly increased, thanks to information given by the PAB, which shows bearing and distance to the person in the water.
Introducing the most advanced EPIRB (Emergency Position Indicating Radio Beacon) available. The new ACR GlobalFix V5 EPIRB combines 406 MHz satellite connectivity with Automatic Identification System (AIS) functionality. This means that when the EPIRB is activated not only does it transmit your emergency signal to the global Cospas Sarsat satellite rescue system, but it broadcasts an AIS safety message on VHF frequencies that can be seen immediately by any AIS equipped vessel nearby. Other great features include Return Link Service (RLS) technology that provides visual confirmation to the user that their distress message has been received, a 121.5 MHz homing signal, and visible and infrared strobe lights for easy target identification at night or in poor visibility. Another new feature is Near Field Communication (NFC) which allows users to monitor their EPIRB using a smartphone App. ACR is the global leader in marine safety and rescue technology and the new GlobalFix V5 GPS EPIRB with AIS combines the durability and reliability they are known for with advanced technology designed to speed rescue response time.

Return Link Service or RLS enables newly approved EPIRB, PLB, and ELT allowing for a confirmation signal (Example: blue light flashing or message if the beacon has a digital display) that the distress signal from the beacon has been received and localized by the Cospas-Sarsat system and forwarded to government authorities for action. It does NOT mean that a rescue has yet been organized/launched, only that the distress alert has been received and routed to the appropriate government agencies. The RLS confirmation signal or message should typically be received back to the RLS beacon between 10-20 minutes as Search and Rescue is working to facilitate your rescue.

The difference is in how the EPIRB is deployed from the provided EPIRB bracket. 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.Both the Category 1 and Category 2 brackets will deactivate the EPIRBs water sensor feature so if the EPIRB should get wet while in the bracket, it will not cause a false alarm. EPIRB water activation is only possible when the EPIRB has been removed from the bracket and gets wet.
Registering the EPIRB, ELT, or Personal Locator Beacon is required by law in the United States and 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.
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 t
