Difference between revisions of "SOS Devices For Backcountry Hikers"

An SOS device is a must for anyone who spends significant time in the backcountry. These devices send distress signals to rescue agencies using private networks and emergency dispatch centers.<br /><br />The most popular SOS devices rely on satellite networks and GPS technology to transmit messages to the GEOS international emergency response coordination center. [https://www.loneworkeralarms.co.nz/ lone worker safety devices] They also include a button that will automatically call emergency contacts in a preset sequence until someone answers.<br /><br />Personal Locator Beacons (PLBs)<br /><br />A PLB (also known as an EPIRB or Emergency Position Indicating Beacon) transmits a personalized distress signal in the 406 MHz spectrum range when activated. Unlike satellite messengers which offer a variety of features, the primary function of a PLB is to send a distress signal that will reach search and rescue agencies worldwide, regardless of where you are on Earth.<br /><br />Once the device is activated, a signal is sent to an international network of search and rescue satellites called COSPAS-SARSAT, which will alert the nearest ground station of your location. The ground station will then contact the Rescue Coordination Centre responsible for your area and organize a response. These are generally very lightweight, compact devices that can easily be stashed in your pack and accessed when needed.<br /><br />PLBs have a long battery life and are designed to lie dormant until you activate them, making them a very convenient emergency signaling device. Most of them will feature a strobe light that can be seen from far away, a high-pitched sound to attract attention and a spring-loaded flap covering the activation button to prevent accidental activation.<br /><br />Some newer models also feature GPS capability, allowing you to send your location along with your emergency signal. This helps SAR teams locate you faster and reduces the chance of confusion when communicating your location with them.<br /><br />Most people will use their PLBs to request help in the event of an accident or other medical emergency while they are out on a hike, mountain bike ride, backpacking trip or other outdoor adventure. However, they are equally useful in the event of a natural disaster such as an earthquake or flood and can be very helpful when you get lost in the wilderness.<br /><br />Like other SOS devices, there are different types of personal locator beacons, so be sure to choose the right one for your activities. Some have GPS, while others only send a distress signal or do not require a subscription fee. Be sure to check the coverage map for each device to make sure it will work in your areas of interest.<br /><br />Satellite Messengers<br /><br />If you’re traveling long distances, a satellite messenger can give you peace of mind. Like PLBs, these devices have an SOS button that, when pushed, sends your GPS coordinates to a private network. These private networks, led by GEOS and Global Rescue, are staffed with response teams that will work to coordinate your rescue (or notify appropriate authorities if it’s an emergency).<br /><br />Satellite messengers differ from PLBs in that they can communicate more nuanced information about your location and situation. They also often come with a built-in GPS navigation and tracking system. Those features aren’t critical for everyday use, but they can be important if you ever need to communicate an urgent message or get lost in the backcountry.<br /><br />A lot of satellite messengers have the added benefit of two-way messaging capability. This is a feature that is becoming increasingly popular among outdoor enthusiasts. It’s similar to text messaging on a smartphone, and most of the satellite messengers we test (including the Garmin inReach Mini 2, SPOT X, ZOLEO, Somewear Hotspot, and the Bivy Stick) come with this functionality.<br /><br />The most common satellite messengers connect to either the Globalstar or Iridium network (the exception is the new Motorola Defy Satellite Link, which uses geostationary satellites). Both systems have extensive coverage in remote locations, although the Iridium network has more operational satellites in orbit compared to Globalstar. We tested a range of devices on both networks to ensure the devices we recommended have the best chance of functioning properly, whether you’re hiking, mountain biking, or soaring on a wingsuit.<br /><br />Regardless of the network you choose, all satellite messengers require a device that’s registered and current, with a clear view of the sky to ensure you can activate the SOS button. In addition, you’ll need to be able to access a wireless network and have the ability to download and install an app (two-way messaging only with some of our picks). It’s worth noting that these devices aren’t a substitute for cellular communication, which should always be your primary method of communication while in the wilderness.<br /><br />Emergency Radios<br /><br />In times of disaster, communication channels can become disrupted or go completely down. Emergency radios, also known as emergency weather radios, provide an essential lifeline in these situations, providing information and safety instructions for residents. They can operate without a continuous power source and are often powered by hand cranks, solar panels, or built-in rechargeable batteries.<br /><br />When choosing an emergency radio, look for one with the ability to receive AM and FM stations as well as NOAA emergency weather broadcasts. A telescopic antenna is also helpful in picking up radio waves. Additionally, look for a device that supports the Emergency Alert System (EAS), which will broadcast national emergencies and regional warnings—including AMBER Alerts.<br /><br /><br /><br /><br /><br />Besides the standard features, most emergency radios come with various accessories to increase their functionality. Many offer additional charging options, such as a hand crank or USB ports, and others have add-ons such as a flashlight or SOS signaling. You may also want to consider a waterproof case, especially if you plan on using your emergency radio outdoors or in inclement weather.<br /><br />Most emergency radios are priced between $20 and $100. This price variation is based on how many features the device has, such as added lights, speaker capability, and additional charging options. The more features an emergency radio has, the more expensive it will be.<br /><br />When selecting an emergency radio, be sure to choose one that is rated for outdoor use. If you're planning on using it in a survival situation, look for a device that has an IP67 rating, which means it can be submerged in water up to 1 meter for 30 minutes.<br /><br />In addition to the basic functions of an emergency radio, you'll also want to select a device that has a flashlight, SOS signaling, and a digital clock. These additional features can help you find your way in a survival situation, and they can also let search and rescue teams locate you more easily. Be sure to buy a model that has a light that can blink or flash in Morse code, as this can be particularly effective at helping emergency responders find you.<br /><br />Choosing an SOS Device<br /><br />Most personal locator beacons and satellite messengers are designed to be clipped to the outside of your pack, which makes sense because they need a clear view of the sky. But they also work just fine when stowed inside your backpack with the protective cover open, which helps prevent accidental activation while hiking and increases the chance that it will be seen in an emergency.<br /><br />The main thing to consider when choosing a backcountry communication device is what sort of messaging you want and require. Most devices use the COSPAS/SARSAT satellite network to transmit SOS messages, which communicate only your location and that you are in distress. The device ascertains your location through GPS triangulation and then broadcasts a message that includes this information on a special distress frequency that can be heard and position-located by aircraft. These devices are best for "life or limb" emergencies since they can't convey more nuanced information about the nature of your situation.<br /><br />Despite their limited one-way capabilities, PLBs are very popular with outdoor adventurers because they're inexpensive (no subscription required), lightweight (4-7 ounces) and durable. They have an extremely simple operation, with only 1 or 2 buttons and a large "activation" button that has a protective cover to help you avoid accidentally activating the device in normal use. PLB batteries typically last for five years and are replaced for free if you activate the device for a life-saving rescue.<br /><br />2-way satellite messaging devices, such as the Garmin InReach Mini and Spot X, are great for people who want to stay in touch with loved ones while on long backpacking trips or multi-day treks but don't want to bring their phone along. All of these devices are paired to their smartphone app and require the use of it to send custom messages, though they can still operate independently of your phone as an SOS device in an emergency.<br /><br />
