Why does my locator signal seem wide?

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

Why does the peak move as I walk?

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

Does a locator show the pipe itself?

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

What if the tone never drops off?

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

Can different frequencies affect pinpointing?

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

Frequently Asked Questions

What is the difference between the Pipehorn 800-H and Pipehorn 800-HL?

The Pipehorn 800-H is a dedicated high-frequency utility locator designed for difficult locates, broken tracer wire, short services, and Safety Sweep verification. The Pipehorn 800-HL includes 480 kHz high frequency and adds 9 kHz low frequency locating, giving crews more flexibility for long-distance tracing, congested utility areas, and changing field conditions.

When should I use high frequency utility locating?

High frequency locating is commonly used when crews cannot directly hook up to the conductor or are dealing with broken tracer wire, poor conductors, short service lines, or difficult locating conditions where the signal may struggle to travel. The Pipehorn 800-H and 800-HL both use 480 kHz high frequency locating to help trace utilities in challenging field environments. They also can be used to verify marks and find unmarked utilities during a Pipehorn Safety Sweep.

When should I use low frequency utility locating?

Low frequency is often used for long-distance tracing and improved utility isolation in congested underground utility areas. The Pipehorn 800-HL includes 9 kHz low frequency locating to help crews follow continuous conductors over longer distances and better isolate individual utility lines.

Which Pipehorn locator is best for broken tracer wire?

Both the Pipehorn 800-H and Pipehorn 800-HL are designed to help crews locate utilities with broken, corroded, or damaged tracer wire using 480 kHz high frequency locating. High frequency signals can often continue tracing where lower frequencies begin to drop off.

Which utility locator is better for congested utility areas?

The Pipehorn 800-HL can help crews better isolate conductors in congested utility areas by using 9 kHz low frequency locating.

Do Pipehorn locators support conductive or direct connect locating?

Yes. Both the Pipehorn 800-H and Pipehorn 800-HL support inductive locating using 480 kHz high frequency. This allows crews to apply a signal without direct connection in many locating situations.

Which Pipehorn locator is best for long-distance tracing?

Because the Pipehorn 800-HL utilizes a 9 kHz low frequency, it can stay better isolated on the conductor and travel further along the target.

What is a Safety Sweep?

A Safety Sweep is a high-frequency locating method crews use to quickly sweep an area for unknown, mismarked, or undocumented underground utilities before excavation. The Pipehorn Safety Sweep is also a great way to get started on the line. Both the Pipehorn 800-H and 800-HL support Safety Sweep verification using 480 kHz high frequency locating.

Does the Pipehorn 800-H or 800-HL locators require annual calibration?

No. The Pipehorn 800 Series utility locators do not require annual calibration, helping reduce downtime and recurring calibration costs for utility locating crews.

Which Pipehorn locator is best for changing field conditions?

The Pipehorn 800-HL is designed for crews working across changing locating conditions because it allows users to switch between 480 kHz high frequency and 9 kHz low frequency locating in the field.

Are Pipehorn locators assembled in the USA?

Yes. Pipehorn locators are assembled in the USA and supported and repaired by the Pipehorn team in Birmingham, Alabama.
