Helpful Hints:
Extension pieces of wire, or long clip leads, can be used to
connect the FOX to a ground or fake ground. The extension
wire can be hundreds of feet long if necessary.
To test a fake ground to see if it can be used for wire tracing,
connect one clip from the FOX to the candidate object (like a
metal desk) and the other clip of the FOX to the target wire.
Hold a HOUND 3 near the object. A “good” fake ground will
not radiate much tracer tone. The tracer tone should be much
stronger on the FOX’s other clip. If it is not, the target wire
may be shorted to ground, or the fake ground may not be
adequate. Generally, the larger the object used as the fake
ground, the better it works.
If the target wire is somehow connected to ground, this will
greatly reduce or kill the tracer tone.
8.1.4.3: Telephone wires:
The floating method is usually used to locate a pair of wires
in a telephone junction block. If the wires are already termi-
nated into a modular telephone jack, simply plug the FOX
into the jack. This method works with the phone line con-
nected or disconnected from the wires going to the telephone
company. A stronger trace is usually obtained if the wires
are not connected to the telephone company.
If the wires are not connected to the telephone company,
the grounded method can be used to trace telephone wires
through a wall or ceiling. Use the green and red clips to con-
