8. Useful information

8.1 Signal Interference
8.1.1 Distorted Fields
Sometimes a single field may encounter metal or other ferrous material
in the ground that may distort the field lines. It may be another utility,
buried scrap or old unused lines that can shunt or shorten the field lines.
In this case the Scout may display a weaker signal around the object and a
stronger signal directly above it. The object may act as a lens that amplifies
or weakens signal unpredictably.
8.1.2 Composite Fields
Composite fields are also possible. Where a single field meets another, the
two, or more, may create a stronger signal. It is important for operators to
understand this around "Ts" or right angles in the line, where composite
fields are often encountered.

8.1.3 Noise
Interfering signals (noise) are simply part of the locating challenge.
Interference can either be at the same frequency 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 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.
8.2 Notes on Accuracy
Depth and Signal Strength measurements rely on a strong signal being
received by the Scout. Remember that the Scout is used above ground to
sense electromagnetic fields emitted from underground lines (electrical
conductors like metal wires and pipes) or sondes (actively transmitting
beacons). When the fields are simple and undistorted, then the sensed
fields are representative of the buried object.

If those fields are distorted and there are multiple interacting fields, it will
cause the Scout to locate inaccurately. Locating is not an exact science. It
does require the operator 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 locator 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 possible and eliminate all connections between the
two lines.

• When using the transmitter inductively. This gives the line a weak
signal. Use a direct connection whenever possible.
• When T's or splits are present in the line. Can cause distortions in
the signal.
• When signal strength is low. A strong signal is necessary for
accurate locating.
• When soil conditions vary. Extremes in moisture, either too dry
or overly saturated, may affect measurements. For example ground
saturated with salty water, that might be found by the coasts, will
shield the signal severely and be very difficult to locate in.

9. Transportation and Storage

Before transporting make sure that the unit is turned off to preserve battery
power.
When transporting make sure that the unit is secure and does not bounce
around or gets bumped by loose equipment.
The Scout should be stored in a cool dry place.
If storing the Scout for an extended period of time, the batteries should be
removed.
10. Installing/Using Accessories
The Scout also comes with markers that can be used to mark Pole or sonde
locations above ground. There are two (2) red markers to mark the poles and
one (1) yellow marker to mark the sonde.
