3 Using the vLoc3 RTK-Pro
NOTE
Note that there will be no sound from the speaker until the meter reading is above approximately 10%
of the full scale.
4. Keeping the vLoc3 RTK-Pro vertical, walk across the area to be checked, keeping the orientation so that the blade is in
line with the direction of walking (See diagram above). If using the Onmi Peak mode, the orientation of the locator is not
important.
5. Continue in a grid across the area.
6. If the meter reading starts to increase at any time, carefully move the locator side to side to detect the maximum signal.
Use the peak level indicator to help confirm the correct position.

7. Rotate the vLoc3 RTK-Pro on its axis to obtain the maximum signal. The vLoc3 RTK-Pro is now directly over the line
and with the blade across the line. (If using the Omni-Peak mode, there will be no change so switch to Peak mode if the
direction is required).
8. The direction can also be found by rotating until the smallest signal is detected. The blade is then in line with the cable/
pipe.
9.
Continue to locate the line's position regularly until its course is known through the target area.
3.1.2
Detecting Radio Signals
1. Locating radio signals is very similar to detecting power signals as they are both passive signals.
2. Hold the vLoc3 RTK-Pro vertically and away from likely positions of cables or pipes.
3. Adjust the sensitivity control so that the bar graph reading is just starting to show some movement. Now follow the
procedure described above in the power mode section.
