New Project Mode and Last Project Mode
New Project Mode: Configure the system as desired. This opens the Change Data Path screen and allows for the
selection or creation of a project folder.
After selecting New Project, select which folder you would like to save your
data to, or create a new folder for a new project.
1 Tap on the arrows and select a folder (project). All files will be saved to
this folder and the name of the files will be folder name + a sequential
number. Tap on Accept to continue.
2 Tap on New Data Path to create a new folder (project).
• Enter and save the new folder (project) name.
• Highlight the new folder (project) by tapping on the arrows.
• Tap on Accept to continue.
3 Tap on Cancel. The files will be saved to the last folder that was used.
Last Project Mode: Bypass the Change Data Path screen and continue with the last project and all of its settings.

• Depth Range: Choose an investigation depth. Preset depth options are available and paired for each
antenna frequency.
• Dielectric Constant: Enter the Dielectric of the soil if known (See Appendix C for more Dielectric
information).
• Soil Type: Choose a basic soil type from a menu of preset types. Each of these has an associated dielectric value.
• Scan Density: Possible choices are: Normal (18/ft or 50/m) and High (36/ft or 100/m).
• Autosave: The system will automatically save each file if this is turned on. When off, the system will prompt you to
save/discard.

Gain Settings
• Gain Mode
• Auto: Allows the system to adjust the Gain Curve (red line seen in the
O-Scope view) automatically based on the quality of the GPR signal.
• Manual: Allows you to adjust the Gain Curve.
• Number of Points
• Number of Gain Points or “Individual Sections” to adjust the Gain Curve.
• Ranges for 1 point to 8 points.
• GP 1-8 (dB)
• If Manual Gain Mode is selection, adjust each Gain Point accordingly.
• Values range from -42 to 126.
Note: Tap on the
double arrows (up
or down) to
display the
appropriate gain
points.

Filters (See Appendix C for more information)
• Stacking (scans): To reduce random or high frequency noise (static or fuzz) in your data. This value should be set
low (3-5). The system will average together that number of scans and output the average value.
• Background Removal (scans): Remove horizontal banding in your data. This value should be set very high. The
system will remove flat bands in the data of that many scans or higher.
• Signal Floor: Shows a visual indicator of noise levels. The shaded green area indicates an area of degraded signal in
which some target types (weak reflectors) may not be readily visible.
• Migration: Allows the computer to estimate a dielectric constant by examining the shape of the hyperbolas.
• Hilbert Transformation: Change all migrated targets from having a negative and positive polarity to just positive
polarity. Good for giving an idea of the strength of the reflection.

LineTrac (Optional Accessory)
LineTrac employs a three-axis 50/60 Hz magnetometer that is used to locate powered and non-powered utilities.
LineTrac can be run in two ways:
• Power Mode: This sensor detection the electromagnetic field generated by flowing AC current. You will need to
set LineTrac to detect either 50 Hz or 60 Hz. Note that Power mode will only detect flowing current, so make sure
that the device attached to the line you are tracking is switched on and drawing current. The Power mode signal
will be displayed in blue. The peak of the curve indicates the utility’s position.
• Frequency Mode: This mode detects a line with a given radio frequency signal “piggybacked” on them. It is
designed to work with common, widely available transmitters (not included). Clip the transmitter to the metallic
utility, the utility’s tracer wire, or non-contact induce the signal as you would with a standard line locator. Select
the matching frequency from the LineTrac menu. The Frequency mode will be displayed in yellow. The detected
target’s position will be in the valley between the two peaks (see images on the following page).
Note that the LineTrac sensor is positioned slightly forward of the GPR antenna’s center position so the target’s signal in
LineTrac will be slightly offset with the GPR’s detected location.
