4.4 Antenna modes
The RD8100 locator supports 5 antenna modes to suit
your particular application or the local environment.
To scroll between locate modes, press the
key.
PEAK
: For accurate locating, the Peak
bargraph provides a visual readout of the
signal strength. The Peak signal is found
directly over the buried utility.
PEAK+
: Choose to combine the accuracy of
the Peak bargraph with Null arrows, which can
indicate the presence of distortion, or with
proportional Guidance arrows for rapid line
tracing
– switch between them by pressing and
holding the
key.
GUIDANCE
: Proportional arrows and a
ballistic directional
‘needle’ combine with audio
left/right indication for rapidly tracing the
general path of a buried utility.
BROAD PEAK
: Operating similarly to Peak
mode, but giving a result over a wider area.
Used to detect and trace very weak signals, for
example very deep utilities.
NULL
: Provides a quick left/right indication of
the path of a utility. As Null is susceptible to
interference, it is best used in areas where no
other utilities are present
For more information on selecting and using the various
antenna modes to assist with cable and pipe location,
refer to Section 5.
