In Radio Mode, the Locator detects signals from various 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
l
Not all services will be detectable in Radio Mode.
l
A strong radio signal present on one service may be masking a weaker radio signal present on an adjacent service.
l
It is not normally possible to determine what the service is in Radio Mode, only it’s position.
l
Radio signals do not favour one utility over another.
l
The depth of the buried service cannot be judged by the strength of the radio signal alone.
l
Normally it is only possible to detect radio signals present on services up to 2 m (6’6”) deep.
l
A short service may not have enough signal to be detected.
Locator Operating Modes:
Radio Mode
NOTE
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.

WARNING
Most buried metallic services not found in Radio Mode should be detectable by using Generator Mode
with the Signal Generator/Transmitter.
