2 vLoc3 Series Receivers
2.9 Alternative Locate Screens
As previously mentioned, the vLoc3 series receivers have alternative locate screens. The following section describes the
operation of these screens. It is left to the user to decide which is the best screen for a particular application.
To scroll through the available screens use a long key press on the Return key.

The Vector Configuration Screen
The Vector Configuration Screen shows a cross-sectional view through the ground. A Plan View is also shown to help orientate
the user over the line. The Vector Screen is particularly useful where access directly over the line is not possible. The depth and
horizontal displacement distances are shown even when not directly over the line.

Using the Vector screen
1. Apply the signal to the target line in the usual manner and select the Vector screen using a long press on the Return button
until the desired screen appears.
2. Position the locator near the position of the target line. Use the Plan View (6) screen to help guide you toward the target
line. You can imagine that the plan view is giving you a view under the ground.
3. Position yourself so that the red target line is pointing forward/back and is in the center of the screen.
4. If the target is off the screen an arrow will appear on the screen to help direct you to the target line.
5. The cross-sectional area of the screen will respond as the target is approached. Use the + and – keys to alter the scaling if
necessary.
6. There is a black line leading from the locator icon to the target line. The blue dot represents the target. Around the dot is
a circle. The size of the circle indicates a confidence factor. The larger the circle, the less confident the indicated position.
Generally, the actual position of the line will be within the confidence circle.
