Quick Answer
Yes, there are PLBs designed specifically for winter sports, often referred to as avalanche beacons or avalanche transceivers, which serve both as a PLB and an avalanche detector.
Avalanche Beacon Requirements
When it comes to winter sports, having a reliable and easy-to-use PLB is crucial. The International Commission for Alpine Rescue (ICAR) and the International Rescue Dog Federation (IRD) both recommend using avalanche beacons that meet the following requirements: a 60 kHz frequency, 91 dB sensitivity, and a 1 second search time. These specific requirements ensure that the beacon can detect a buried person quickly and accurately.
Using an Avalanche Beacon as a PLB
While an avalanche beacon is primarily designed for detecting buried people, it can also be used as a PLB in emergency situations. To do so, simply flip the switch to the “send” or “transmit” position, which will activate the beacon’s PLB signal. This signal will be transmitted to emergency services, allowing them to locate you and provide assistance. It’s essential to note that the PLB signal will only last for 24 hours, and it’s crucial to have a plan for long-term survival in case of an extended emergency.
Choosing the Right Avalanche Beacon
When selecting an avalanche beacon for winter sports, consider the following factors: user interface, battery life, and weight. Look for beacons with intuitive interfaces and long battery life to minimize distractions and ensure you have a reliable signal. Additionally, consider the weight of the beacon, as a lighter unit will be easier to carry on long expeditions. Some popular models include the Backcountry Access Tracker DTS, the Ortovox S1+ UL, and the Mammut Barryvox S. Whatever model you choose, make sure it meets the ICAR and IRD recommended specifications for avalanche beacons.
