Scout™ Sonde and Line Locator
Notes On Accuracy
Noise
Interfering signals (noise) are simply part of the locating
challenge. Interference can either be at the same fre-
quency being used, or it can be "out of band" at other
frequencies. Some of the largest interfering signals are
generated by power transmission equipment. Power
transformers, large electric motors or generators and
lines can be the source of very large noise signals. Areas
that are particularly noisy should be avoided if that is
possible.
If the angle display is unstable and not steady, and/or if
the signal levels are not steady, this is a good indication
of either no target signal present (sonde or energized
line), or a high level of interfering noise.
Locating Is Not An Exact Science
Locating is not an exact science. It does require the op-
erator to use judgement and look for all the information
available beyond what the instrument readings may be.
The Scout will give the user more information but it is up
to the operator to interpret that information correctly. No lo-
cator manufacturer will claim that an operator should
follow the information from their instrument exclusively.
Conditions when locating accuracy must be questioned:
• When other lines or utilities are present. "Bleed
over" may produce distorted fields and illuminate lines
unintentionally. Use lower frequencies when possi-
ble and eliminate all connections between the two
lines.

• When using the transmitter inductively. This gives
the line a weak signal. Use a direct connection when-
ever possible.
• When Ts or splits are present in the line. Can
cause distortions in the signal.

• When signal strength is low. A strong signal is nec-
essary for accurate locating.
• When soil conditions vary. Extremes in moisture,
either too dry or overly saturated, may affect measure-
ments. For example ground that is saturated with salty
water, that might be found by the coasts, will shield the
signal severely and be very difficult to locate in.
