An avalanche beacon is a small device that helps find people buried under snow during an avalanche. It sends a radio signal that other beacons can detect. When someone is buried, the beacon switches from transmit mode to search mode. This helps rescuers locate the person quickly.
Why is an Avalanche Beacon Important?
Avalanches can happen suddenly and bury people under heavy snow. In such situations, time is very important. A beacon can save lives because it helps rescuers find victims faster than digging randomly. The first 15 minutes are critical for survival.
How Does an Avalanche Beacon Work?
Most beacons work on a standard frequency of 457 kHz. When you travel in snow areas, your beacon is in transmit mode. If an avalanche occurs, the beacon keeps sending a signal. Rescuers switch to search mode to detect the signal and find the buried person.
Parts of an Avalanche Beacon
A typical beacon has:
- An antenna
- A display screen
- Buttons to change mode
- A battery compartment
- A harness or strap
The antenna sends and receives signals. The battery powers the device, so it must be fully charged before traveling.
What Modes Does a Beacon Have?
Most beacons have three main modes:
1. Transmit Mode
This is used when you are moving in avalanche terrain. It sends a signal continuously.
2. Search Mode
Used when someone is buried. It helps find the signal from the victim.
3. Mark Mode
Used when multiple people are buried. It allows you to mark a found signal so you can search for others.
Why Training is Important
Carrying a beacon is not enough. You must know how to use it correctly. Many avalanche courses teach:
- How to switch modes
- How to search
- How to dig safely
- How to use a probe
Practice is very important because in real emergencies, you must act fast.
What Other Tools Do You Need?
A beacon alone is not enough. You also need:
- Shovel – to dig the buried person
- Probe – to find the exact location
These tools work together. The beacon helps you find the area, the probe pinpoints the exact spot, and the shovel helps dig.
How to Stay Safe in Avalanche Terrain
Avalanche safety is not only about equipment. You must also:
- Check weather and avalanche forecast
- Travel with experienced people
- Avoid risky slopes
- Keep a safe distance from each other
- Plan your route carefully
How to Maintain Your Beacon
Beacons need regular maintenance. Always:
- Check the battery before each trip
- Test the device with your group
- Avoid dropping or damaging it
- Keep it in a secure harness
What Happens After an Avalanche?
If someone is buried:
- Switch your beacon to search mode
- Follow the signal
- Use the probe to locate the exact spot
- Start digging with the shovel
- Provide first aid if needed
Can a Beacon Save Your Life?
Yes, a beacon can save lives. It helps rescuers find buried victims faster. But it must be used correctly, and you must act quickly.
