About EPIRBs, PLBs, & SARTs

EPIRBs

Category 1 and 2 marine EPIRB and marine distress beacon kits offer battery-operated safety measures for small boats and commercial rigs alike. Manual release or water-activated EPIRBs fit a variety of budgets and safety needs.


An Emergency Position Indicating Radio Beacon (EPIRB) is a device used to alert search and rescue services in the event of an emergency, such as a ship or aircraft accident. The device is designed to automatically transmit a distress signal on the 406 MHz frequency, monitored by satellites and search and rescue authorities worldwide.
EPIRBs have been used since the 1970s and have played a crucial role in saving lives in emergencies. These devices are typically carried on boats and aircraft and can also be found on oil rigs and other offshore structures. When activated, the EPIRB sends a unique identification code and GPS location to search and rescue authorities, allowing them to locate and assist those in distress quickly.
One of the key features of EPIRBs is their ability to transmit a distress signal even when other forms of communication, such as radios or cell phones, are unavailable or damaged. As a result, it makes their equipment for boaters and pilots operating in remote areas or areas with poor communication coverage.
There are two types of EPIRBs: manual and automatic. Manual EPIRBs require the user to activate the device manually, typically by pulling a trigger or pressing a button. Automatic EPIRBs, on the other hand, activate automatically when submerged in water, making them especially useful for boating accidents.
In addition to the traditional EPIRBs, personal locator beacons (PLBs) are designed for use by individuals. These devices are smaller and more portable than conventional EPIRBs and are often carried by hikers, campers, and other outdoor enthusiasts. Like EPIRBs, PLBs transmit a distress signal on the 406 MHz frequency but have a shorter range and are designed for use on land.
Various mobile applications allow users to send their location during an emergency, known as Emergency Location Services (ELS). These apps typically use GPS data from the user's phone to provide search and rescue authorities with an accurate location. These services should be used as a last resort or in conjunction with traditional EPIRBs or PLBs, as mobile networks might not be available during an emergency.
Overall, EPIRBs and PLBs are essential tools for ensuring the safety of individuals in emergencies. They provide a reliable and fast means of alerting search and rescue authorities to a person in distress, even in remote and difficult-to-reach areas.
It is also important to mention that these devices must be registered and maintained regularly. It ensures that the information is up to date and that the device works properly in an emergency. It also allows the rescue team to contact the beacon's owner and ask for further information.

Personal Locator Beacons (PLBs) provide emergency communication and location services in remote or wilderness areas. They are typically small, portable, and easy to use and can be activated by the user in case of emergency to alert search and rescue teams of their location.
PLBs communicate a distress signal on the 406 MHz frequency, monitored by the international search and rescue system known as COSPAS-SARSAT. This system is operated by a network of satellites and ground stations that can detect the distress signal and determine the location of the PLB within a few kilometers. Once the signal is received, the location and identification information encoded in the beacon's signal is used to alert the appropriate search and rescue authorities, who dispatch a team to the location.
PLBs are intended for use in wilderness or remote areas where traditional forms of communication may not be available. They are beneficial for outdoor enthusiasts such as hikers, climbers, and boaters, as well as for people working in remote locations such as oil rigs, mines, or survey crews. In addition to providing location information, PLBs can transmit data such as identifying the beacon's owner and any medical or other special needs they may have.
One of the critical benefits of PLBs is that they do not rely on any infrastructure or communication network to function. It means that they can be used in places where cellular or satellite phone coverage is unavailable and provide an emergency communication link when other forms of communication have failed. In addition, PLBs are typically more rugged and durable than other communication devices and are designed to withstand harsh environments.
While PLBs can be a lifesaver in emergencies, it is essential to note that they are not a substitute for other forms of communication or safety equipment. For example, it is always best to let someone know your itinerary and expected return time before heading out into the wilderness and to carry other forms of communication, such as a satellite phone or a two-way radio, in an emergency. Additionally, PLBs require batteries that have to be replaced periodically. Also, users must be familiar with their devices and test them regularly to ensure that they are in proper working condition.
Overall, Personal Locator Beacons are essential for anyone venturing into remote or wilderness areas. They provide reliable communication in an emergency and can significantly increase the chances of survival and rescue. Carrying one on your adventure is always recommended if you are in a remote area.
