Having found a signal the next step is to pinpoint the source.
The closer the Locator is to the signal source the stronger
the response.
To Pinpoint a Signal
1. Keeping the Locator vertical, walk through the area of the
signal response. If the visual response goes up off the scale
then stop and reduce the sensitivity of the Locator slightly
before continuing.
2. The width of the signal response will shrink as the
sensitivity is reduced. Once it is reduced enough then a
clear peak response will be seen on the display as the
Locator traverses the service. The Locator is positioned
directly above the buried service when the display is at its
highest
(

)
reading.
3. Carefully rotate the Locator over the peak reading until the
visual response falls to a minimum. The Locator will now be
roughly IN LINE with the direction of the buried service.
4. Mark the position of the buried service.

NOTE
The amount of sensitivity adjustment needed to pinpoint a service can vary depending on the mode being
used, the signal strength and the service depth.
