3 Using the vLoc3 RTK-Pro
11. Note that it may be necessary to confirm the Sonde position when directly over the Sonde, left to right. Do this by moving
the locator left to right to identify the strongest signal's position, as indicated on the bar graph. At this time, the depth of the
Sonde will be displayed at the top of the display.
12. Having pinpointed the Sonde position, it can now be pushed into a new location and the process repeated. It is advisable to
keep the survey intervals too short distances such as six feet (two meters), making locating easier.
