• The FOXs tracer tone will penetrate wood frame walls and
ceilings, and plaster and drywall. Under good conditions, a
HOUND can pickup the tone from a foot or more away from
the target wire.
• The FOXs tracer tone will pass through any electrical cir-
cuitry connected to the target wire(s). Hence, to identify a
specific wire, it will be necessary to disconnect all loads and
circuitry from the wire. This includes switches, capacitors,
resistors, coils, transformers, lights, motors, etc.
• The FOXs tracer tone can be shorted out by any loads on
the target wire. All loads must be disconnected from the tar-
get wire.
• Wet drywall, wet cinder block walls, or any wet wall sur-
face will also shield the FOX signal, preventing the HOUND 3
from detecting its presence.
• The actual wire being wet can shield the signal. The wire
can be wet internally, shielding the signal. This phenomena
has been observed in “Romex” electrical wire. The internal
paper separator can get wet from exposure to the weather.
The exterior surface of the Romex can be dry, but because
the internal paper separator is wet, it shields the tracer sig-
nal.
• Extremely high humidity will reduce the effectiveness of
the HOUND 3 in finding the FOX signal. Condensing atmo-
spheres may even cause the products to malfunction until
they dry out.
