Selecting frequencies
It is important to select the correct or appropriate
frequency for your particular application. For more
information refer to the application note “The theory of
buried cable and pipe location”, which is available as a
free download from https://www.radiodetection.com/en-
gb/cable-and-pipe-location-theory.
To select a frequency on the locator:
1 Press the key to cycle through available
frequencies
2 Alternatively, hold down the key and press the
or keys to cycle up or down the range of
frequencies
If locating using an active frequency you must also set
your transmitter to output the matching frequency.
You can change your transmitter’s output frequency
manually using your transmitter’s keypad or automatically
using iLOC (Bluetooth transmitters only).
To manually select a transmitter output
frequency:
1 Press the key to cycle through available
frequencies
To change frequencies using iLOC, refer to Section 11.
NOTE: Some frequencies require that you connect an
accessory, for example an A-Frame, before the frequency
is available.
6.3 Antenna modes
The RD8200SG system supports five antenna modes,
exclusively dedicated to locating cable and pipes, and to
suit your particular application or the local environment.
These are:
 Peak mode
 Peak+ mode
 Guidance mode
 Broad Peak mode
 Null mode
Peak mode
Peak mode provides the most sensitive and accurate
mode for location and depth measurement. It provides a
sharp Peak response with a corresponding small
decrease in sensitivity. Peak mode cannot be disabled
using the menu.
In Peak mode the following indicators are displayed by the
LCD:
 Depth
 Current
 Signal strength
 Compass
To select Peak mode:
1 Press the key until the Peak mode icon is
displayed on the LCD
NOTE: The depth and current values will display
automatically, although these values should not be
considered accurate until the locator is directly over the
target line.
Peak+™ mode
Peak+™ mode combines the accuracy of the Peak
bargraph with a choice of Guidance or Null directional
arrows.
Guidance arrows provide visual indication of the direction
to the target utility, and are designed to get you close to
the Peak position faster, before using the Peak bargraph
to pinpoint the target utility,
Using Null arrows allow you to check for distortion before
marking a point, and should be used when accurate locate
measurements are required.
Switching between arrow types:
When in Peak+ mode, press and hold the key to toggle
between Guidance and Null arrow types.
You can also select the default arrow type in the locator
menu:
1 Press the key to enter the menu
2 Scroll to the ARROW menu using the or keys
3 Press the key to enter the ARROW menu
4 Select NULL or GUIDE using the or keys
5 Press the key twice to return to the main locate
menu.
When using Guidance arrows:
Use the proportional arrows to guide the locator along the
path of the target cable or pipe. To accurately locate the
center point of the target utility, for example to mark a point
or take a survey measurement, use the Peak bargraph to
pinpoint the Peak position.
