Line Scan
RD1500 Operation Manual 38 © Radiodetection 2016
The depth scale along the side of the GPR Line image and the position scale along the top of
the image are set to Metric or US Standard units based on the setting in the Preferences menu
(6.1.2)
If Auto-Hide Buttons is set to ON (Section 6.1.5), the menu at the bottom of the screen
disappears as soon as you start collecting new data, thereby maximizing the data display area.
When the user stops, backs up or presses a button on the keypad the menu reappears.

8.3 DynaQ™
The RD1500 uses DynaQ, an advanced patented technology that adjusts data quality as the
system movement speed varies. In most situations, moving the system at a comfortable walking
speed generates data of good quality. In situations where target resolution or maximum
penetration depth is critical, moving more slowly increases data quality.
As the Line Scan data scrolls on the screen, the DynaQ Index Bar is displayed along the bottom
of the screen (Figure 8-3). The color of the bar indicates the quality of the data at that point
along the line:
White = No Data (too fast!)
Yellow = Moderate quality
Light blue = Better quality
Dark Blue = Highest quality
