The final phase of a transceiver search, in which you systematically pinpoint where to start probing.
As you get within about 3 meters of the buried transceiver; you begin the fine search. Now it’s time to slow down to a crawl. By using a systematic bracketing technique, you hone in on the lowest distance reading. While keeping the transceiver in the same orientation, slowly move it up, down, left, and right across the snow surface to narrow in on the lowest reading. Mark and take note of this reading; it is the approximate burial depth (in meters) that you will be probing for.
