Choosing the Right Pipe and Cable Locating Equipment

Selecting the correct locating equipment is critical to safety, accuracy, and compliance with Australian standards. Whether you are a telecom contractor, civil engineer, or utility worker, the type of underground service you need to locate will determine which technology is most appropriate for the job.

For locating live electrical cables, gas mains, water pipes, and telecommunications conduits, electromagnetic pipe and cable locators are the industry standard. The Radiodetection CAT and Genny range is widely trusted across Australia for its reliability and advanced signal processing capabilities. For ferrous metals such as steel pipes, survey pins, and manhole covers, a magnetic locator such as the Schonstedt Maggie provides excellent sensitivity and pinpoint precision.

When working in environments where non-metallic pipes are present without a tracer wire, Ground Penetrating Radar (GPR) from Sensors and Software provides subsurface imaging that can detect both metallic and non-metallic structures simultaneously — an essential capability for complex utility environments.

What to Look For When Selecting a Locator

Not all locating jobs are the same. Key factors to consider when choosing equipment include:

• Signal frequency range: More frequencies mean greater versatility across different cable and pipe types and depths.
• Depth measurement: Advanced models provide real-time depth readings to help plan safe excavations.
• GPS and data logging: Survey-grade options allow you to record locate data in the field and integrate with GIS mapping systems.
• Marker detection: If your network uses buried marker balls or EMS markers, ensure your locator includes a compatible detection mode.
• IP rating and durability: Australian field conditions demand rugged, impact-resistant equipment with high IP ratings for dust and moisture protection.

Frequently Asked Questions

What is the difference between a CAT locator and a Genny?

The CAT (Cable Avoidance Tool) is a passive and active receiver that detects signals from buried cables and pipes. The Genny (Signal Generator) is a transmitter that applies a signal to a cable or pipe so the CAT can actively trace its exact path. Used together, they form the foundation of safe underground service detection across Australia.

Can I locate non-metallic pipes with an electromagnetic locator?

Standard electromagnetic locators cannot detect non-metallic pipes (such as HDPE or PVC) unless a tracer wire or sonde has been installed alongside the pipe. For non-metallic services without tracer wires, Ground Penetrating Radar from Sensors and Software is the recommended solution.

What equipment do I need for DBYD Accredited Locator certification?

DBYD Accredited Locator requirements vary by state and network operator. TMG can supply a complete kit including a pipe and cable locator, signal generator, and accessories tailored to your specific accreditation requirements. Contact our team for a personalised recommendation.

Do you offer rental locators for short-term projects?

Yes. TMG offers flexible rental options for Radiodetection locators and GPR systems — ideal for covering peak workloads, replacing equipment that is out for calibration, or trialling new technology before committing to a purchase.
