The second phase of a transceiver search after a signal is acquired, in which you follow the flux line until you are close to the buried transceiver.
Once you’ve acquired a consistent signal with directional lights, you enter the coarse search. In this phase of the search, you slow your pace down from running speed to walking speed. Follow the distance readings and directional lights on your transceiver as it brings you to within about 3 to 5 meters of the buried victim. If the distance readings increase enroute, turn around and follow the same line of travel in the opposite direction. Keep the transceiver oriented in the same direction during this phase of the search to ensure a consistent signal.
