If you enjoy hiking or backpacking into the backcountry, you know how important it is to make sure that you stay safe. While most of your adventures should unfold without incident, you never know when you could find yourself in an emergency where you need somebody else to come out and find you. In these situations, a personal locator beacon (PLB) can mean the difference between life and death.

What is a Personal Locator Beacon?
Personal locator beacons have been in existence since 2003. Their primary purpose is to send out a personalized distress signal in case of an emergency. While they are high-powered (usually operating on 5 watts), they do need an unobstructed view of the sky to work.
You can compare a personal locator beacon to an Emergency Position Indicating Radio Beacon (EPIRB). EPIRB technology has been in use for far longer, but only at sea.
How Does a Personal Locator Beacon Work?
A personal locator beacon allows you to transmit your distress signal directly to the authorities. This is done through a network of military satellites provided by the United States, Canada, France, and Russia. Collectively, these satellites are called COSPAS-SARSAT, which stands for “Search and Rescue Satellite Aided Tracking.”
Your beacon is transmitted at 406 MHz, which is a frequency used internationally for distress signals. Both NOAA and the Air Force Rescue Coordination Center (AFRCC) monitor this frequency on an ongoing basis. Once the satellites transmit your distress call, they will check your position and AFRCC will immediately launch a rescue effort.
Questions to Ask When Shopping for a Personal Locator Beacon
Do you need a PLB or an EPIRB?
Both devices broadcast on the same frequency and alert the nearest Rescue Coordination Center (RCC). The main difference between them is that an EPIRB is designed specifically for use at sea, whereas a PLB can be used at sea, but is more appropriate for a land-based environment. A PLB must be held in an upright position, but an EPIRB will float upright on its own. More EPIRBs include strobe lights, and they also may include a feature where they signal for help automatically when a vessel sinks.
Where geographically will you be using the device?
Some PLBs only allow you to make use of certain features in particular geographic regions. So for example, if you are going to be hiking in the Swiss Alps, you would not want to buy a device that will only offer you GPS in the US.
Will you use it in the water?
While you can use a PLB in the water, you may want to consider an EPIRB instead. Then again, it depends on your plans. An EPIRB would be a better choice for regular fishing or diving expeditions at sea, but if you are a hiker who simply goes on the occasional boating excursion, a PLB might still be the better all-around buy. Regardless, if you know you will use the device in a watery location (lake, river, sea, even a spot that gets a lot of rainfall), make sure you look for waterproofing.
Features and Add-Ons to Look For When Shopping for a Personal Locator Beacon
If you think you might ever need help in a hurry, GPS compatibility is an excellent safety feature. With it, you can transmit your exact GPS coordinates to rescue workers. This saves them (and you) from having to wait for the satellites to extrapolate your position.
This is a capability included with some newer models of personal locator beacons. With it, you can test whether the GPS receiver is properly operating and pinpointing your location. You can only perform the GPS Satellite Acquisition Self-Test a few times over the life of the gadget since it is a real drain on the battery (more on this below).
There are two important aspects to consider:
1-Shelf life of the battery when the PLB is not transmitting
2-Life of the battery while transmitting
You want both to be as long as possible. The first is important because a PLB is a one-use item in the sense that you either need to buy a new one after the battery expires or you have to send in for a replacement battery from the manufacturer (thus why you can only run the self-test so many times). The second is important because your life depends on it.
The wider the range here, the better. You might find yourself needing rescue from a location with extreme temperatures.
This is a feature which is more commonly included with an EPIRB, but nowadays you may also find a strobe light on a PLB.
Water-resistance and floatation
If you will be in a watery environment, floatation and water-resistance are both excellent features which can save your life. Here are the ratings which you can look for in the product specifications:
- IPX0: No water resistance
- IPX1: Protection from vertical drops
- IPX2: Protection from vertical drops and drops at an angle 15 degrees
- IPX3: Protection from spray up to 60 degrees
- IPX4: Protection from splashes in any direction
- IPX5: Protection from water jets from any direction
- IPX6: Protection from powerful jets
- IPX7: ACTUAL WATERPROOFING in up to three feet of water
- IPX8: ACTUAL WATERPROOFING in more than three feet of water
