The signal strength bar graph will change color with the
level of signal distortion:
Green: Low distortion electromagnetic eld
Blue: Minor distortion in the electromagnetic eld
Red: Excessive distortion electromagnetic eld

TIP
When in a locate screen, pressing and holding the “f”
key will bring up the frequency table.
Use the “+” and “-” keys to navigate quickly to the
desired frequency. Press the “i” key to select a
highlighted choice and return to the locate screen.
2.10 Classic Locating Modes (Response)
The vLoc3 RTK-Pro receiver has an array of six antennas, and these can be toggled through di󰀨erent congurations (modes) to
provide di󰀨erent responses to the signals radiating from buried utilities. The modes are:
2.10.1 Peak Response Mode
Two horizontal antennas provide a “Peak” or maximum signal response over the buried line.
This is an accurate locating method as both horizontal antennas are used to provide a clearly
identiable “Peak.” It is also less prone to the e󰀨ects of signal distortion.
The Peak Level Indicator on the bar graph indicates the point of the largest signal detected,
allowing the user to return to this point quickly.
The compass (line direction indicator) aligns itself parallel to the cable (available in Active modes).
