In Radio mode, the locator detects signals from radio transmitters. These signals flow through the ground and will tend to
follow the line of least resistance such as a buried metallic service. When this happens the service can often be detected
by using the locator in Radio mode.
Limitations of Radio Mode
●
Not all services will be detectable in Radio mode.
●
A strong Radio signal present on one service may be masking a weaker Radio signal present on an adjacent service.
●
It is not normally possible to determine WHAT the service is in Radio mode, only it’s position.
●
Radio signals do not favour one utility over another.
●
The depth of the buried service CANNOT be judged by the strength of the radio signal alone.
●
Normally it is only possible to detect Radio signals present on services up to 2 metres deep.
●
A short service may not have enough signal to be detected.
Locator Operating Modes:
Radio Mode
NOTE Most buried metallic services not found in Radio mode should be detectable by using Generator
mode with a Signal Generator.
WARNING Locators can only detect services radiating a detectable electromagnetic signal.
There may be some services that do not radiate these signals and cannot be located.
