What is a Personal Locator Beacon?

A Personal Locator Beacon (PLB) is a small electronic transmission device to send signals to the nearest rescue team during a life-threatening emergency, accident or attack in a remote location.

In general, an activated PLB is capable of sending two types of signals simultaneously:

  • 406MHz frequency to the Search and Rescue Satellite-aided Tracking System (SARSAT)
  • 5MHz frequency to local Search and Rescue (SAR)

We are familiar with the perilous routes, incidents occurring during the journey to the backcountry, and on cruises. Several emergency situations can arise during the tour urging the need to seek help or medical aid. Based on our experience with different PLB systems available in the market and the opinion of users (for some models) we have prepared a list of the top 10 models.

In this article, we have provided every bit of information including the review of the best PLBs in the market to help you choose the perfect one for your requirements.

Frequently Asked Questions

Now that you have at least 10 options in mind, it is quite likely to have some queries in the mind. Before you contact the customer support team for a pre-sale query, herein are the answers to commonly asked questions customers often have in their minds about PLBs.

Which is the best PLB?

No two PLBs are the same. All of them are different with varying features, functions, etc. Every model serves your need to transmit emergency signals to the rescuers but there are certain basic considerations when choosing a model.

For instance, if your route is mainly through landscape areas, then you do not need to spend extra to get a waterproof mode. However, you may be crossing rivers during the expedition. In that case, you may go a bit higher with at least a buoyant PLB for greater safety.

Do I need a personal locator beacon?

Undoubtedly, PLBs are expensive. There is often a consideration in the mind whether this is even worth having one.

Unfortunately, mobile phone or other devices may not be sufficient to send security alerts to a rescue team if there is an urgency to get help. When your loved one is carrying an industry-standard best emergency locator beacon, it gives you peace of mind at home even miles away.

I wish you never have to use it. But, in case of a mishap such suffering with a broken leg in the backcountry alone, encounter a MOB attack, or stuck by a marine tornado an activated professional-grade EPIRB can help you to get in touch with the nearby rescuers.

This is the most convenient way for you to send a signal to the rescue team and get help at the earliest.

Can you rent a personal locator beacon?

Yes, there are some providers offering PLBs on rental scheme. The charge is generally imposed on per day basis. It can be anywhere around $10 or higher for one day.

How much does a PLB cost?

The cost of a PLB can range anywhere from $300-$800 depending on the features, model, brand, and other factors.

In general, the PLBs with complete waterproof housing can be highly expensive. Hence, if you are looking for the best personal locator beacon yachts, sailing, boating, or marine expeditions, it is worth considering a highly functional EPIRB.

How does a personal locator beacon works?

Herein is a step-by-step guide on how PLBs work to help you receive aid from a Search and Rescue (SAR) team.

  1. All PLBs have a push button that you can turn on to activate your device.
  2. Upon activation, PLB is capable of transmitting signals (digital encoded data) at 406MHz to the SARSAT.

There are two types of SAR satellites-

  • Low Earth Orbit (LEO) satellites- Use Doppler Shift computation to determine the location of the PLB from which it is receiving the signal.
  • High Earth Orbit (GEO) satellites- These are geostationary orbit satellites capable of tracking exact location of the distress signals only when sent through a GPS enabled PLB. These satellites cannot use Doppler Shift computations to determine the PLB’s exact location.
  • The SARSAT system upon receiving the signal encodes the data. There are two possible scenarios determining how you will receive help from the rescuers:
  • Signal Transmission from GPS Enabled PLB: The signal from your PLB is first received by the GEO satellites. If you are sending signal from a GPS-based PLB, it can quickly transfer the data about the signal and its precise location to the SAR team for further proceedings.
  • Signal Transfer from PLB without GPS: Since the GEO satellites cannot interpret the exact location information from the non-GPS PLBs, the rescuers have to wait for the location details.

They will get the location tracking once the signal is traced by an LEO satellite. These satellites are not static so it may take up to an hour or more for the SAR team to get the details before then can proceed for the rescue operations.

Note: Misuse of PLBs is strictly forbidden. You should only activate the device only if there is an instance when you are in need of urgent help. Sending false alerts may attract strict penalties and imprisonment sentences for up to 6 years.

How long do PLB batteries last?

A standard PLB battery will last for a minimum period of 24 hours. However, if you are using an EPIRB, it is able to keep transmitting signals for at least 48 hours or even more.

Register Your Personal Locator Beacon

To make sure you are able to send a signal to the local Rescue and Search team, it is extremely important to register your device with the National Authority of your country. This may differ from one nation to another.

For instance, if you are a resident of the U.S., visit the official website of the National Oceanic and Atmospheric Administration (NOAA). This organization regulations the rescue operations in the country with the help of the Search and Rescue Satellite-aided Tracking System (SARSAT).

To register your new PLB with NOAA, visit the official device registration website: https://beaconregistration.noaa.gov/rgdb/.

You will find all the guidelines related to device registration norms in the US and the steps to register your PLB with NOAA.

After you complete the registration process, NOAA will send you the authorization sticker that you need paste on your PLB.

Things to Consider Before Buying Best Personal Locator Beacon

As you may have already realized that there are several models and popular PLB brands in the market. It can be really overwhelming and confusing to choose the right one to meet your needs.

Read below the aspects to take note of when buying your next PLB so that you get the best emergency locator beacon worth your money and suits your requirements:

Network Coverage

If you are an American resident then your device may be registered with NOAA. However, you can carry it anywhere when backpacking for a trip to Alps, Antarctica, etc.

*COSPAS-SARSAT are government military satellite networks having coverage across the globe. There are other private satellite networks such as Iridium (supporting Garmin PLBs) and Globalstar offering similar surveillance support. However, Globalstar does not cover remote areas on the poles and Africa.

When buying your device, check for the satellite network supported by the model.

* COSPAS is the acronym used for Space System for the Search of Vessels in Distress in the Russian language.


While both the devices perform the same function of transmitting distress signals to the SAR satellites, there are some basic differences worth taking note of before choosing your emergency locator beacon:

  • Size and Weight: PLBs are lightweight small devices often designed for handheld bearing or attached to an arm gear. EPIRBs are comparatively heavier to carry along and generally designed to mount in boats, ships, and other vehicles for use during emergencies.
  • Water-Resistance and Buoyancy: Most EPIRBs are fully waterproof designed for floating on water. Some PLB models are also designed for buoyance and suitable for carrying on yachts, boats, and sea cruises.
  • Battery Life: There is a huge difference in battery life of PLBs and EPIRBs. When fully charged, a standard PLB can store it for 6 years and transmit signals for up to a minimum 24 hours. A fully charged EPIRB can store charge for 10 years and transmit signals continuously for 48 hours and even more.
  • Device Registration: EPIRBs are not for personal use and registered only for vehicles or vessels. PLBs are small devices basically for personal use and registered in the name of the user or owner.
  • Device Activation: There are distinct mechanism in both EPIRBs and PLBs to prevent accidental activation. There is a magnetic collar and a water activation switch on EPIRB for activating the device. These features are not present in PLBs but have a three-step activation process to prevent unintended activation.

Why Choose GPS-Based PLBs

As discussed earlier, the signal transmitted from a GPS-enabled PLB is directly recognized by the static GEO satellites immediately. It is able to trace your exact location based on the information received from the GPS channels. Thereupon, it sends information to SAR team to take quick action.

If you are not using GPS-based PLB, it can be rather difficult for the teams to track your location. It can take even a few hours for them to locate you and take adequate measures.

Is It Safe to Buy a Previously Owned PLB?

There are several risk factors for travelers using a pre-owned PLB device:

  • How old is the Beacon?

It is vital to know the exact date of manufacture of the beacon. It is also difficult to determine if the PLB has been serviced before. The details about the manufacture date and servicing records can give you an idea of the present condition of the device. You can also take a self-test to see if it is functioning properly.

  • Have you purchased a previously registered PLB?

If you have purchased a pre-owned beacon, ask the previous owner whether it is a registered device or not. If registered, the person should send a request notification to NOAA to cancel the present registration. Upon cancellation, the new owner will be able to register the device in his name.

  • Ask the Owner about the Battery

If you are buying a previously owned device, it is important to know about the battery expiry date. If it has been replaced previously, it can be highly expensive to replace the battery again. In that case, it is worth buying a new device at a lesser cost.

  • Check the Tamper-proof Seal on the PLB?

To ensure the beacon has not been opened before, check if there is blue tamper-proof seal on one of the screws. If opened previously, it can be risky to use a tampered device.

  • Is the Beacon Programmed for Your Country?

 Always check for the country code for which it is programmed. You need a device programmed for your country to ensure it works in the location you desire to visit. Otherwise, you need to reprogram it for the country you are visiting.

To Summarize,

If you are already backpacking for an adventurous tour, the PLB is the most reliable and highly efficient security system everyone should use.

It is more powerful in transmitting signals in remote locations where your phone network or GPS features may not work. Most standard PLBs have high-performance battery life that lasts longer than a fully charged Smartphone battery.

Those who are in need of a lightweight device for secure signal transmission for personal use may consider buying a PLB with a mounting arm gear. For novice users planning a trip to backcountry or journey through land routes, ACR PLB-375 ResQLink+ is definitely a considerable option to get started.

However, if you are looking for a professional-grade device, ACR GlobalFix Pro 406 2844 EPIRB is a great choice.

The devices in this list were chosen based on their performance, reliability, and features to help you with the possible options before buying.

I hope that this extensive review and essential tips will ease your problem in choosing the best PLB before your next expedition.
