In general, avoid collecting data at extremely high rates of speed. The system senses if the
Sensor Head is moved too quickly and will beep three times to indicate that a data quality issue
has been detected.

6.5 Back-Up Indicator

Line Scan mode incorporates a back-up feature to enable you to accurately locate targets and
mark them on the ground. After acquiring some data on the screen, move the system
backwards and crosshairs will appear over the collected data showing the current position of the
Sensor Head (Figure 6-6).
Figure 6-6: Line Scan mode data display. Moving the Sensor Head backwards during data collection displays a Back-
up indicator with crosshair, used to pinpoint the position and approximate depth of an object.
For example, if you pass an object in the concrete, simply roll the Sensor Head back along the
same path until the vertical red line appears exactly over it. The object is located at the center of
the Sensor Head (Figure 3-19). You can mark the position of the object on the surface and
continue data collection. On the bottom of the screen, your horizontal position is indicated (top
number), relative to the start of your line.
To determine the depth of an object, move the small horizontal crosshair up or down using the
keypad buttons on the Display Unit, or just drag the crosshair up or down on the screen.
Measure depth to the top of the highest band in the object response. Note: make sure you have
done a Concrete Cal to ensure depth accuracy
