crosstalk, but other wire/cables crosstalk readily. So much
crosstalk can occur that the tracer tone on the adjacent wires
can be almost as large as the original tone on the target
wire. This can make it difficult to identify the target wire with
the HOUND 3. The traditional method of trying to determine
if the tone being received is the original tone, or is crosstalk,
is to short out the wires with the tone where the HOUND 3 is
being used. If shorting the wires only reduces the tone’s level,
but does not completely kill it, then the shorted wires have
crosstalk on them, and are not the target wires. If shorting
the wires completely kills the tone, then its likely that the
wires are the target wires. Unfortunately, this is not 100%
effective. The FOX 2 uses TrueTrace . . . a test technique
which greatly improves the accuracy of the trace. Shorting
the target wires together causes the cadence (the speed at
which the tracer tone warbles or pulses) of the tracer tone
to change, positively identifying the target wire(s).

Helpful Hint:
If the suspect wires are longer than they need to be, the user
may not need to strip the wire to bare metal in order to acti-
vate the True Trace feature. Select a pair of suspect wires.
While listening with the HOUND 3 or a cordless phone (see
Cordless Interface), use a pair of wire cutters (diagonal
cutters usually work best) to slowly apply pressure to the
wires. The metal jaws of the cutters will bite through the
insulation of the wires as pressure is applied, shorting out
the wires and causing the cadence of the tone to change.
The pressure can then be released, or the ends of the wires
trimmed off.
