.
Current flows best from the smallest lines to the largest
(lowest resistance) lines. An example would be tracing
.
a pipe from the house to the street.
While tracing, the signal should maximize, and the
depth minimize, at the same place where the lines cen-
ters on the display. If this is not the case, the utility may
.
be turning or other coupled signals may be present.
Higher frequencies bleed over more but may be need-
ed to jump breaks in tracer wires or go over insulating
.
couplers.
When using the transmitter inductively be sure to begin
the locate 10/15m away to avoid "air coupling". This is
where the Scout will pick up the signal from the trans-
mitter directly and not from the line to be traced.
Micro map - Example – Line Trace
While tracing the micro map assumes the following conditions:
a. The ground is level.
b. The line is level.
c. The Scout Locator is above ground level.
d. The Scout antenna mast is held approximately verti-
.
cal.
If these conditions are not met, pay close attention to
maximizing signal strength. In general, if the Scout is
within about two "depths" of the line, the map will be
useful and accurate. Be aware of this when using the
micro map if the target or line is very shallow. The use-
ful search area in micro map can be small if the line is
extremely shallow.
