Question 1

Why does my locator signal seem wide?

Accepted Answer

Sensitivity (gain) is likely too high. Lowering sensitivity tightens the signal field and makes the center easier to identify.

Question 2

Why does the peak move as I walk?

Accepted Answer

This can occur when signal is coupling onto nearby conductors or when grounding is poor.

Question 3

Does a locator show the pipe itself?

Accepted Answer

No. A locator detects the electromagnetic field around a conductor, not the physical pipe.

Question 4

What if the tone never drops off?

Accepted Answer

The receiver sensitivity is set too high or the signal is bleeding onto adjacent utilities.

Question 5

Can different frequencies affect pinpointing?

Accepted Answer

Yes. Higher frequencies tend to spread more easily onto nearby conductors, while lower frequencies stay tighter to the intended line.
