4.4 Antenna modes
The RD8200SG 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.
4.5 System setup
The RD8200SG locator and transmitter settings can be

currently installed type. This is to ensure optimal
performance and correct battery level indication.
To set your transmitter battery type:
1 Press the key to enter the menu
2 Scroll to the BATT menu using the or arrows
