3 Using the vLoc3 RTK-Pro
The vLoc3 Sonde Screen will display the Large Peak as a Sonde icon
and the Null Points as double blue circles, as shown in the illustration to
the right.
Method
1. Switch on the vLoc3 receiver and use long presses on the Enter key to enter the Sonde screen.
2. Press the “f” key to select the sonde frequency matching the sonde being located.
3. Insert the activated sonde into the pipe. Push the sonde about 10 – 12-feet (3-4m) into the pipe.
4. Hold the locator vertically and stationary with the tip on the ground.
5. When the receiver is within the sondes range, a screen similar to the one below will be seen. On the screen, the arrow will
be pointing to the sonde. The bar graphs on either side of the screen are identical and indicate the signal strength. Use the
+ and – keys to alter the receiver gain to keep the signal within the bar graph's limits.

6. If the bar graph is not steady, it will most likely be because the sonde is not within range. In this case, hold the locator at
approximately 45 degrees to the ground and rotate the locator around a full 360 degrees around you.
Note the strongest signal's direction and walk towards it until the bar graph shows a steady signal. Now revert to step five
above.
7. Walk slowly in the direction of the arrow.
8. A double circle will appear on the screen, indicating the position of a null signal. Walk toward it and position it over the
crosshairs of the screen. Now rotate the locator so that the arrow is pointing forward.

9. Keeping the null indicator on the vertical line, walk toward the arrow.
10. A Sonde icon will soon appear. Keeping the locator vertical, carry on walking toward the Sonde until it is positioned on the
crosshairs. The locator is now directly over the Sonde. The arrow will flip forward and back as the position is crossed.
