Operating Tips for Line Tracing

• When the lines are not centered on the map, but sig-
nal strength is maximized, distortion is present!
a) Try changing to a lower frequency.
b) Move the ground stake position away from the line
to be traced.
c) Make sure that the line is not commonly bonded to
another utility.
• If the lines will not center or if they move across the
screen inexplicably, then the Scout may not be re-
ceiving a clear signal.
a) Check the transmitter to be sure that it is operat-
ing and well grounded.
b) Test the circuit by pointing the lower antenna at ei-
ther transmitter lead.
c) Check that the Scout and transmitter are operat-
ing on the same frequency.
d) Try different frequencies, starting with the lowest,
until the line can be picked up dependably.
• While tracing, the signal should maximize, and the
depth minimize, at the same place where the lines
centers on the display. If this is not the case, the utility
may be turning or other coupled signals may be pre-
sent.

• Higher frequencies bleed over more but may be
needed to jump breaks in tracer wires or go over in-
sulating couplers.
• When using the transmitter inductively, be sure to
begin the locate 40 to 50 ft away to avoid "direct cou-
pling". This is where the Scout will pick up the signal
from the transmitter directly and not from the line to be
traced.

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
vertical
• 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
useful search area in Micro map can be small if the line
is extremely shallow.
