2 vLoc3 RTK-Pro Receiver
“Tram” lines either side of the line indicate an area of confidence. The closer the tram lines are together, the greater the
confidence.
In addition to the tram lines, the color of the target line also changes depending on the degree of confidence:
Green: - low distortion/high confidence.
Blue: - Minor distortion/medium confidence, proceed with care.
Red: - Excessive distortion/low confidence, treat all data and measurements with caution.
4. If the target is off the screen, an arrow will appear on the screen to help direct you to the target line.

5. As long as the locator is detecting a valid signal, the depth (or current) will be available regardless of locator orientation, i.e.
the locator does not need to be aligned with the target line in the forward back orientation. It is recommended that, in this
mode, the current is always displayed as it is possible signal will bleed off onto other services. Regular checks on the signal
current i.e. checking for large changes, will ensure the correct line is detected.

6. A short press on the info button will display the information screen. More information relating to the information screen is
described in a previous section, “Information Pushbutton (Depth & Current).”
Transverse Plot Screen
The Transverse Plot screen is used to analyze the field shape at a particular location. This enables the user to get a better feel
for the reliability of the data gathered.
Two plots are generated simultaneously.
●
Peak response
●
Null response
In non-distorted fields, the peak and null positions should coincide, and the shape of the fields should be symmetrical about the
centerline. The picture below shows a slightly distorted field.

To take a plot, first locate the target using one of the other locate screens. Now select the Transverse screen by a prolonged
press of the return button. Repeat this until the Transverse screen appears.
Position yourself to one side of the line such that the field markers are just on the screen. You will see that the lines automatically remove
themselves after a set period of a few seconds. Clear the screen by pressing the “ –” button. Now walk across the line of the target at a
steady pace until you are on the other side of the target line. Immediately press the “+” button to save the plot on the screen.
It is still possible to walk back over the target, locating the position of the line when in the transverse screen while still retaining
the saved screen.
