How to Locate a Service Using the Sonde
1. Walk in line with the suspected direction
of travel observing the display. The signal
strength indicator will rise and fall as you
pass over the ghost signal at the back of
the Sonde, the peak signal directly over
the Sonde and the ghost signal at the
front. The numeric signal strength indi-
cator will display its highest value when
detecting the peak signal.
2. Retrace your steps and position the
locator directly over the peak signal.
Move the locator left and right until the
highest numeric reading is obtained. This
reading will indicate the Sonde's precise
location.
