Rule of frequency selection says Use the lowest
frequency that will produce a traceable signal over
the distance you need to cover.
They make locating easier because they typically
stay on one conductor, reduce possibility of signal
distortion and require fewer hook ups to trace
a longer line.
- Helps isolate the target line = Less Bleed-Over.
- Travel further down low resistance or uninsulated
- Work well on larger diameter conductors.
|Can’t overcome high resistance, i.e.
Stubs, Insulated joints, Dry/Sandy soil, no
far end ground, etc.
Not useful for blind searches/sweeps when
you just want to identify the existence of any
conductors in an area.
Not useful for inductive locating.
Susceptible to power line interference
Lowers receivers sensitivity

Won’t travel far down a line.
Does not work as well on larger diameter conductors.
They make locating possible in situations that
have high resistance but they can increase signal
distortion and confusion in congested areas.
