What Is the Difference Between Power Mode, Radio Mode and Genny Mode? Malaysia
Introduction
One of the most frequently asked questions when purchasing an underground utility locator is:
"What is the difference between Power Mode, Radio Mode, and Genny Mode?"
Understanding these three locating modes is essential for achieving accurate underground cable and pipe detection. Each mode is designed for different situations, and knowing when to use them can improve locating accuracy, reduce excavation risks, and save valuable time on site.
The Tomkat V2 Pipe & Cable Locator features all three professional locating modes, making it a versatile solution for contractors, utility companies, surveyors, and maintenance teams throughout Malaysia.
What Is Power Mode?
Power Mode detects the electromagnetic field generated by live electrical cables carrying alternating current (AC).
The receiver detects these naturally occurring signals without requiring a transmitter.
Best Used For
Live underground power cables
Building electrical supplies
Street lighting cables
Distribution power networks
Advantages
Fast and simple to use
No transmitter connection required
Ideal for preliminary safety checks
Suitable for locating energized cables
Limitations
Only works effectively on live electrical cables.
Cannot accurately locate plastic pipes or non-energized metallic utilities.
What Is Radio Mode?
Radio Mode detects naturally occurring radio frequency signals that travel along underground metallic utilities.
These signals originate from broadcast transmitters and are induced onto buried metallic conductors.
Best Used For
Metallic water pipes
Steel gas pipelines
Metallic conduits
Unknown underground utilities
Initial site investigations
Advantages
No transmitter required
Useful when direct cable access is unavailable
Can locate various metallic utilities
Limitations
Signal strength varies depending on environmental conditions.
Accuracy may be lower than Genny Mode in congested underground environments.
What Is Genny Mode?
Genny Mode works together with the SIGEN 2+ Signal Transmitter.
Instead of relying on naturally occurring signals, the transmitter applies a dedicated locating signal directly onto the cable or pipe.
The Tomkat V2 receiver then detects this signal with much higher precision.
Best Used For
Utility locating before excavation
Long cable runs
Congested underground services
Metallic pipes
Communication cables
Fibre optic ducts (with tracer wire)
Professional utility surveys
Advantages
Highest locating accuracy
Longer tracing distance
Reduced interference from nearby utilities
More reliable route identification
Recommended for professional contractors

When Should You Use the 5m Sonde?
The 5m Sonde (33kHz) is included in the SIGEN 2+ Builder's Kit.
It is used for locating:
PVC drainage pipes
Sewer pipelines
Plastic conduits
Underground ducts
The Sonde emits a detectable signal, allowing the Tomkat V2 to trace the route of non-metallic underground utilities.
Which Mode Should You Choose?
Each mode has its own purpose:
Power Mode – For quickly locating live electrical cables.
Radio Mode – For surveying unknown metallic underground utilities.
Genny Mode – For the highest accuracy when tracing specific cables or pipes.
For most professional excavation and utility locating tasks, Genny Mode with the SIGEN 2+ Signal Transmitter delivers the most reliable results.
Why Choose Tomkat V2?
The Tomkat V2 offers:
Detection depth up to 3 metres
Three professional locating modes
Visual and audible alerts
Easy-to-use interface
Compatible with the SIGEN 2+ Signal Transmitter
Includes 100mm Signal Clamp and 5m Sonde (33kHz)
Suitable for construction, utilities, telecommunications, and industrial maintenance
