  7. 8. Is there a better alternative?
  8. 9. Moving in Avalanche Country <ul><li>Reduce Risk </li></ul><ul><ul><li>Spread out </li></ul></ul><ul><ul><li>Expose only 1 person </li></ul></ul><ul><ul><li>Keep an eye on everyone </li></ul></ul>

  13. 14. The Rescue Primary Search >40m Secondary Search 40-3m Pinpoint Search <3m Objective: Detect strong signal Objective: Get close to buried Transmitter (approx. 3 meters) Objective: Locate strongest signal, Minimize probe/dig area
  14. 15. The three search phases would look something like this for a single searcher: 1. Primary Search 2. Secondary Search 3. Pinpoint Search .
  15. 16. What about two searchers ? 1. Primary 2. Secondary 3. Pinpoint Probe and shovel! .
