Signal Search

A transceiver search consists of three phases:

  1. The signal search is when you are looking for a signal from the buried victim's transceiver.
  2. The coarse search happens when you have a signal and can start to focus in on the victim's location.
  3. The fine search takes place when you're about 3 m from the buried victim.

The videos and images on this page demonstrate the key points of the signal search.

  • Ensure everyone's transceivers are on search mode.
  • Look for visual clues on the surface of the debris.
  • If you have a last seen point, start there.
  • Carry out the signal search in a systematic fashion.

Any transceiver that remains in send mode will introduce another signal to the search, confusing and slowing the rescue effort.
