4.3 Distance Sensitive Left/Right Guidance™ Display
The Left/Right display is tremendously useful in refining the precise location of the target line.
The vertical green bar represents the underground utility and when shown on the left of centerline
it indicates the target is also to the left.
Figure 4-4 Distance Sensitive Left/Right Guidance
Using Metrotech’s Distance Sensitive Left/Right Guidance feature, the deflection distance of the
vertical black bar away from the center of the display is proportional to the distance off center
from the underground line. Although this is strictly true only when the field is free of distortion, the
Left/Right display still plays an important role in sorting out what is going on in the underground
utility environment.
Figure 4-5 Distance Sensitive Left/Right Guidance
Often the receiver is used in a swinging motion over the centerline of the tracked utility. When
the action in the Left/Right display is non-symmetric, this can be a warning of the presence of
distortion in the field. Care should be taken to determine the effect of other cables in the locate
zone that might be creating distortion by carrying bleedover and return currents.
