Search Techniques
Due to the highly directional nature of the 457 kHz signal at the ranges common for avalanche burial (and the range specified in the standards), there have been many techniques developed to search for buried beacons. Good beacon search abilities are considered a required skill for recreational backcountry skiers, mountaineers as well as avalanche professionals such as ski guides, ski patrollers, search and rescue volunteers and professionals. Recreationalists and professionals alike take part in drills, practice and scenarios as a regular part of avalanche skills training.
The burial of a single beacon may involve search using one of several methods:
- Grid search
- Induction search
- Circle method
These search methods are adapted and extrapolated to scenarios where there is more than one burial.

Famous quotes containing the words search and/or techniques:
“Man is eminently a storyteller. His search for a purpose, a cause, an ideal, a mission and the like is largely a search for a plot and a pattern in the development of his life story—a story that is basically without meaning or pattern.”
—Eric Hoffer (1902–1983)
“It is easy to lose confidence in our natural ability to raise children. The true techniques for raising children are simple: Be with them, play with them, talk to them. You are not squandering their time no matter what the latest child development books say about “purposeful play” and “cognitive learning skills.””
—Neil Kurshan (20th century)
