Start
To start the system, press
the power button on the
display unit.
Once the system boots up,
you will see the main screen.
Line Scan Mode
Line Scan enables the operator to locate a feature and easily back-up
and mark the location of that object on the ground. From the main screen,
press the Line
Scan button;
you will see the
screen shown
below.
Grid Scan Mode
Grid scans are conducted to generate depth slices over a given area.
From the main menu press
the
Grid Scan
button to
enter the Grid setup menu.
From here you can set the
grid number grid size and
grid resolution (also known
as Line Spacing).
Press Start to enter Grid
Acquisition.
Align the system so that the longitudinal axis is centered on the first line.
Then line up the middle of the sensor with the starting line and press
Start.
Push the system in a straight line towards the end of the line.
Data acquisition will automatically stop once you reach the end of the line.
The Line Scan image of the data just collected
will appear on the left side of the screen.
The grid picture on the right shows the
collected lines (red), current line (white) and
remaining lines to be collected (green). Move
to the next line, and repeat until all X lines and
Y lines are collected. When you have finished,
press the Slice View button.
Slice View
Slice View displays data collected in a grid as a series of depth slices
moving deeper into the subsurface.

Power button
Swipe your finger from the top of the screen towards the bottom. This will
show a drop-down menu displaying date, battery level, GPS status and
Wi-Fi status. To close the drop-down menu, touch anywhere on the screen
below the menu.
Press the
Start
button to begin collecting data. The screen will change to
the data acquisition screen. As the system is pushed along a straight line,
the collected GPR data scrolls onto the screen from the right and moves
to the left.
Pressing the + and - buttons on the
Depth
button will increase or decrease
the depth of the depth slice currently displayed. This allows the user to “slice
through” the ground, and locate features that appear at different depths.
To locate targets, move the system back along the same path until the red
vertical line is exactly over the response (usually a hyperbola). You can mark
the location of the object on the surface and continue data collection. Viewing
options can be adjusted using the menu at the bottom of the screen.
