Radiodetection Line Locators
Precision utility locating, survey-grade mapping, and RF marker detection, from the brand crews trust most.
Radiodetection line locators trace buried pipes and cables quickly and accurately, so crews can work with less risk and stronger documentation. The current lineup pairs precision locating with advanced filtering, RF marker detection, and survey-grade GPS options, which is why utility, telecom, power, gas, and municipal teams rely on it in congested underground environments.
As an equipment dealer, our job is to match you to the right model, not the most expensive one. We work with contractors, municipalities, and survey crews every day, and every purchase comes with free on-site training, free 24/7 support, and factory-authorized repair for as long as you own the equipment.

How to choose
The right locator depends on how and where you work, not on brand or price alone. Five things to weigh:
Utility type. Metallic lines call for electromagnetic locating; PVC, HDPE, and other non-metallic pipe need acoustic or GPR.
Frequency and signal control. Multi-frequency models give you more control in congested or electrically noisy sites.
Depth and verification. Look for stable depth readings and current measurement to confirm you are tracing the right line.
Environment. Urban work rewards advanced filtering; rural work rewards range and penetration.
Budget and ROI. The right system pays for itself by preventing strikes, rework, and downtime.
