How to Choose and Use an Avalanche Transceiver
In snowy backcountry areas, an avalanche transceiver, also known as a beacon, is considered ‘essential gear,’ along with a probe and shovel. If you’re well-trained in its use, a transceiver can significantly increase your chances of a successful rescue in avalanche scenarios.
How it Works: they continuously emit a radio signal that can be picked up by other transceivers in the area. It’s critical for rescuers to locate buried victims. They operate on the 457 kHz international standard, which is compatible across brands. You must wear the beacon close to your body and secure it so that it won't be thrown during an avalanche.
When shopping for a transceiver, prioritize these features:
Multiple antennas for precise locating: the three-antenna design allows you to pinpoint the location of the victim.
Display screens: these are for directional guidance and distance to the avalanche victim.
Audible signals: for proximity alerts so you know when you’re getting closer to the victim.
Batteries: most transceivers use replaceable alkaline batteries, ensuring gradual energy drainage for reliable performance. Follow manufacturer recommendations for battery type and storage. Remember to remove batteries in the off-season to avoid corrosion.
Practice: use your transceiver regularly and follow manual instructions for wearing and carrying it. Always keep it in "send" mode until a search is necessary.
Interference: minimize electronic interference by keeping transceivers away from other devices, i.e. cell phones, Go Pro, or radios.
Transceiver Checks: ALWAYS conduct a trailhead transceiver check with your group before heading out. Ensure everyone's transceiver is functioning properly in both send and search modes.
Battery levels: if less than 75%, replace with new batteries
To confirm that everyone’s ‘search’ function is working: set one transceiver to send/transmit mode, while everyone else switches to search mode. If everyone receives the ‘send signal,’ you’re good to go.
Ensure everyone's ‘send’ function works: one team member walks about 20 meters down the trail and turns on search mode. Other members take turns passing by that person with the send/transmit mode on to verify their signal.
Everyone in the group MUST be in "send" mode before heading out.
