Locating Congested Utilities with
the Direct Mode
The Direct Mode in the Transmitter together
with the lowest frequency are the best
strategy for locating lines in areas with con-
gested utilities.
1. Select the Direct Mode in the PL-2000
Transmitter and choose either the 8
kHz or .5 kHz frequency. If the primary
conductor to be located is continuous,
like a steel gas line or a tracer wire,
then choose the .5 kHz frequency. If the
primary target is a water main, choose
8 kHz. For an insulated tracer wire,
remember to ground the far end.
2. Connect the positive (red) cable to a
metal tting connection or valve in the
target line. Position the ground stake for
the negative (black) cable very close or
directly over the top of the target line.
This minimizes energizing the adjacent
lines.
3. Because the ground stake is so close to
the target line, the distance located will
be relatively short.
Locating Branches in Pipelines
and Water Services from the Main
Locating branches in pipelines and service
lines from water mains can be done in the
Direct Mode or the Inductive Mode, but
usually the Direct Mode is preferred. In the
Direct Mode at 8 kHz, the PL-2000 Trans-
mitter has maximum power.
1. In the Direct Mode, select a location for
the ground stake that is on the same side
of the main as the branch pipeline or ser-
vice line. Put the stake 10-15 feet away
from the main to maximize the power
delivered to both.
2. Use “Peak” Operating Mode to have the
greatest accuracy for locating the branch
line or service line.
3. Walk parallel to the water main 5-10
feet away from it in the area where the
branch pipeline or service line is ex-
pected to be. Hold the PL-2000 Receiver
parallel to the main and facing in the
direction of the branch or service line.
When the Receiver crosses over the line,
it should respond immediately.
