Locator Operating Modes:
Radio Mode
NOTE
Most buried metallic services not found in Radio Mode should be detectable by using Generator
Mode with the Generator or Transmitter Mode with the Transmitter.
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.
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
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.
