Walking the line is where everything you did at the transmitter either pays off or falls apart.

Use the proper technique while designating buried utilities and make sure you know the limitations of your equipment.

Set your ground properly, parallel to the expected direction of the utility you are trying to designate. Verify with area sweeps and adjust based on your findings.

Frequency selection isn’t about the utility. It’s about what’s around it. One of the most common mistakes I see in the field — techs defaulting to the same frequency every single time regardless of the environment. That’s how you end up marking the wrong line. Here’s how I think about it: 512 Hz is your long distance specialist. Minimal signal bleed, ideal for trace wire and telecom runs. Direct connect only — inductive clamp won’t work at this frequency. 8 kHz is your everyday workhorse. Solid range, works with both direct connect and inductive clamp, good balance between signal strength and bleed control. 33 kHz gives you a stronger signal and better clamp performance — but in a congested utility corridor, that stronger signal bleeds onto adjacent lines. Know what’s around you before you dial it in. The environment drives the frequency choice. Always.

The three frequencies:
512 Hz
Long distance | Trace wire | Minimal bleed
8 kHz
Everyday workhorse | Direct connect & clamp
33 kHz
Stronger signal | Watch bleed in dense corridors
