Quick Answer
The optimal approach for avalanche beacon use involves a clear and methodical search pattern, thorough signal verification, and precision pinpointing of the buried victim.
Pre-Search Preparation
Before initiating a beacon search, ensure you have a clear understanding of the terrain, the last known location of the buried victim, and the avalanche slide path. Activate your own avalanche transceiver and set it to “transmit” mode, if not already in use. This step is crucial for identifying a signal source and determining the direction of the slide.
Search Pattern and Signal Verification
To begin the search, divide the area into a grid, typically 5 meters by 5 meters (16.4 feet by 16.4 feet). Sweep your probe and avalanche beacon in a slow, zigzag pattern, overlapping each section by a meter (3.3 feet). When you detect a signal, turn off your transceiver to avoid interference and begin to probe the suspected location of the buried victim. Verify the signal with a second sweep of the area to confirm the location and ensure the signal is not a false reading.
Pinpointing the Buried Victim
Once you have confirmed the location of the buried victim, use your probe to create a shallow trench, about 30-40 cm (11.8-15.7 inches) deep, centered on the suspected location. Carefully sweep the probe back and forth, searching for resistance or a change in the probe’s movement. When you encounter resistance, stop probing and carefully dig around the identified location.
