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.

Pipehorn Signal Clamp 5″

$585.00

The Pipehorn Signal Clamp (5″) is a valuable accessory designed for use with Pipehorn 800 Series transmitters when direct connection to a conductor is not possible. Instead of inducing signal through the ground, the clamp allows you to apply a stronger, more isolated signal directly onto an accessible conductor, improving locate accuracy and signal clarity.

The clamp works by placing the ring around the target conductor—such as a pipe, cable, or tracer wire—and transmitting the Pipehorn signal through the conductor itself. This method is especially useful in situations where grounding points are difficult to access or when a more controlled signal is needed.

The Pipehorn 5″ Signal Clamp fits conductors up to 5 inches (12.5 cm) in diameter, making it ideal for a wide range of utility locating applications across gas, water, telecom, and electrical infrastructure.

When properly positioned, the clamp helps deliver a cleaner signal path between the transmitter and receiver, allowing crews to trace utilities more confidently and identify the correct line in congested areas.

Pipehorn Signal Clamp 5″

An accessory used along with a transmitter, the 5″ Signal Clamp enables inductive coupling to trace inaccessible conductors without making a direct connection, providing safer and more efficient line detection.

Who It’s For:

Utility workers and locate crews needing to find live cables, conductors within a conduit, or isolate wires within a bundle without shutting down the system or exposing an end that can be connected to.
