Antenna Modes
The RD7200 locator supports 4 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. |
 |
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. |
