frequency key.png

Scroll through locate frequencies from low to high

In active locating:
When using Current Direction™:
Perform a CD Reset

antenna key.png

When using active frequencies: Toggle Peak, Peak+, Null, Broad Peak and Guidance antenna modes.

In Power Mode: scroll through Power Filters™ for improved discrimination of parallel or strong signals.

In UTIL mode: Scroll through a list of utilities: GAS, TEL, SEW, TMA, H2O, PWR, EXL, IRR, CTV

In Peak+ antenna mode: Switch between Guidance and Null arrows.




up and down keys.png Increase and decrease gain. RD8200 automatically sets gain to mid-point when pressed. Rapidly increase and decrease gain steps in 1dB increments.
survey key.png Take a survey measurement and send over Bluetooth if paired. Switch between utilities whilst in UTIL mode.
transmitter key.png Send an iLOC command to a paired transmitter. Enter the transmitter power setting menu for use over iLOC.


Transmitter key actions

measure key.png Take voltage and impedance measurements using selected frequency. Take voltage and impedance measurements at a standardized frequency.
up and down keys.png Adjusts the output signal. Select standby down arrow /maximum standard power.up arrow

NOTE: to scroll through frequencies from high to low, holdfrequency keywhile pressing the down arrowbutton (applies to both locators and transmitters).


Antenna Modes

The RD8200 locator supports 5 antenna modes to suit your particular application or the local environment.

To scroll between locate modes, press the antenna key.png key.

peak mode.png 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+ mode.png 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 antenna key.png key.
guidance mode.png 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.png 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 mode.png 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.
