Problems
Distortions in the electromagnetic field around a cable can affect location accuracy. Tees, bends, parallel
cables, crossing cables, or large metallic objects can distort signals.
IMPORTANT:
If target depth and location are critical, confirm by hand-digging or vacuum excavation.
Learn to recognize the following kinds of distortion:
Shadows
Shadows, also called blind spots, often happen when a metallic object partially obstructs the signal, or a
signal from a parallel cable interferes with target signal.
Secondary
(Ghost)
Signals
A typical beacon signal pattern shows a main signal and two weaker secondary signals. Identify
beacon location at the main signal. Familiarity with beacon signal patterns will lessen the effect
of ghost signals.Using the Total Field antenna mode will eliminate ghost signals. See
