The coarse search begins when your transceiver picks up a signal. A number will appear on the screen; this is the distance to the buried transceiver. You will also see a direction indicator.
Move quickly in the direction indicated. If the number decreases, you are getting closer. If the number increases, turn around 180° and move until you see the numbers decreasing.
Slow down when you get about 10 metres away. At three metres, you are ready to start your fine search.
