The Peak Method
The concept of the ‘peak’ method is illustrated in the following drawing.
When the HotWire Hound is passed perpendicularly over the wire with the HotWire Fox’s tracer signal,
a strong signal will be picked up as the Hound passes over the target wire. The signal will be strongest
directly over the wire.
Peak signal pick up usually happens when short wires are being traced, and the wires have no predomi-
nant RF path to earth ground.
On a long wire run, the signal near the HotWire Fox may display null characteristics, and gradually change
to peak characteristics towards the far end of the wire.
Crosstalk and TrueTrace:
Crosstalk is the bleeding of the tracer tone from the target wire onto adjacent wires. This often happens
in multi-wire cables, or in cable harnesses where many wires are bundled together in close proximity to
each other. A tracer tone applied a pair of wires may crosstalk onto adjacent wires. Some wires/cables are
constructed to reduce the crosstalk, but other wires/cables crosstalk readily. So much crosstalk can
