• “File____XXX” – The filename of this scan if you choose to save this file.
3 Move your cart forward. Data only gets collected when you move the cart forward.
4 Once you start seeing hyperbolas on the screen, pull the system straight back along your
survey line. You will see a vertical line (the backup cursor) scroll along your data.
When that vertical line is right over the apex of the hyperbola, the center of the antenna
is over that target.
Note: When you pull the Mini HR straight back, and if you configured Auto Target On, the Mini will interpret
target locations by placing yellow dots on the targets.

5 The center of the antenna is directly under the Mini HR. After marking the location of the target on the ground
using the laser (if configured On) at each side of your cart as a guide (or the groove on each side of the cart as a
guide if the laser is configured Off). Push the cart straight forward or move the cart to do another line scan. No
data will be collected until you have passed the spot where you started to reverse.
6 If you wish, you may calibrate depth (optional). Match the target location in the data to its location in your survey
area. Drill down to that target and measure the depth.
a) Backup the Mini HR and press “Depth Cursor” to display crosshairs and set them over the target in the
data.
b) Press Ï Ð to line up the horizontal line in the middle of first dominant color of that
target.
c) Press to Set Depth.
d) Press Ï Ð until the Depth in the upper left hand corner matches the measured
depth.
e) Press Í to Set Depth. The vertical scale will adjust and the dielectric will be
updated. Please note that this is only an approximation of the true depth because the
dielectric value or constant can change with depth and across the site.
f) Press Î to continue scanning.

9 Other Options
• While collecting data (with no backup cursor on the screen), press and HOLD Ï (New File) to save your
current file. If you have configured Save Prompt On, you will be prompted to confirm the save. Press Ï to
save, Ð to not save the data. If you have configured Save Prompt Off, it will save automatically.
• Press Í to place a user mark in your data.
• Press Î to exit. If you have configured Save Prompt On, you will be prompted to confirm the save. Press Ï
to save, Ð to not save the data. If you have configured Save Prompt Off, it will save automatically.
Helpful Hint: Make a sketch map of your survey area with immovable objects as reference points. Sketch in your survey
files, note the start and stop points, direction of travel, and file name on the map. This will make it much easier to relocate
your targets after the survey.
Helpful Hint: The top of a target is generally the middle of the first positive peak for metal targets (rebar, tensioned cable,
wires in PVC, conduit). If you are working in a grayscale color table, the positives are white. If the utility is air or gas
filled (empty PVC, voids) the top of the target is the middle of the first negative peak (black). Please refer to Appendix C
for examples of the different types of data.

2 From the Main Menu,press Î to select Playback
a) Highlight 3D Project and press to select the appropriate project and then select
the appropriate Grid.
b) Highlight Playback and press to process and draw the grid.
Other Playback Menu Options
Auto Depth – Press to toggle between On and Off.
• On – The Mini HR will estimate the depth of targets and automatically adjust the
Depth Scale.
• Off – The Mini HR will use the original value set during collection.
Auto Gain - Press to toggle between On and Off.
• On – The Mini HR will reconfigure the gain.
Quick Start Guide StructureScan Mini HR
Geophysical Survey Systems, Inc. 35
• Off – The Mini HR will use the gain used during data collection.
Contrast - Press to toggle between Lowest, Low, Medium, High, Highest.
• The lower the contrast, the more “positive” colors are displayed.
• The higher the contrast, the more “negative” colors are displayed.
• See the color scale below to see how much color is displayed as you toggle through these options. Low or
Medium are good defaults.
Color – Press to toggle between colors for display of the data.
Lowest Medium Highest
Once the Mini HR has processed the data, it will display the grid. You will be in Depth Slice Mode as noted at the bottom
of the screen.

Modes
You may press the Enter button to toggle between different modes for display and edit purposes.
They are: Depth Slice Mode, Cursor Mode, Color Mode, and Select Profile Mode.
Depth Slice Mode
1 The initial display will be the Full Range of the grid. Pressing the Ï from the Full Range will
decrease the range depth by ½ inch (1.27 cm) increments. Pressing the Ð will slice down
through the image in ½ inch (1.27 cm) increments. Note the top of the screen. It will display
the depth of the slice or the total depth of the slice.
2 Press Í and hold for two seconds to Exit.
3 Press Î to save the image as a .bmp file.
4 Press to toggle to Cursor Mode.
Cursor Mode
This will display crosshairs on the data so that X and Y coordinates located at the top of the screen
may be noted as the location of a target.
1 Press Ï Ð buttons to move the crosshair in the Y Direction.
2 Press Î to change the menu to the X Direction Mode so that you may move the crosshair in
the X Directions by pressing Ï Ð.
3 Note the X and Y coordinates at the top of the screen as you move the cross hairs.
4 Press Í to set a mark at the location of the crosshairs.

• Press Ð to place a dot at the location of the crosshairs.
• Press Í to place a line following the vertical line of the crosshairs.
• Press to return back to Edit Mode View.
5 Press to toggle to Color Mode.
Color Mode: Allow to change data color and contrast
1 Press Í to toggle between different colors.
2 Press Ï Ð to change the contrast of the screen.
3 Press to toggle to Select Profile Mode.

• Press Î to change the gain
• Press to set the new Dielectric.
3 Press to return to Depth Slice Mode
Note: When changing and setting the dielectric, the system will redisplay the data. The goal is to have “dots”
instead of hyperbolas’.
Dielectric Too High,
Hyperbola tails point down.

Appendix B: Battery/Charger Information
Your system comes with a two-slotted battery charger and adapter. It also comes with
three international interchangeable plugs.
• To charge your batteries, simply attach the adapter to the charger and plug in the
adapter. Insert one or both batteries. The batteries will charge one at a time. The bars
located at the top of the batteries will indicate how much charge is left in the battery.
• At times, you may wish to re-calibrate a battery. Simply insert a battery into the slot
on the left and press the RECAL button
• LED Lights – As the batteries are charging, the LED lights for each slot will do
different things.
• No Lights – No Batteries
• Green Flash – Fast Charging
• Green Solid – Fully Charged
• Yellow Flash – Recalibrating
• Yellow/Green – Recalibrated
• Yellow Solid – Standby
• Red Flash – Error
Quick Start Guide StructureScan Mini HR
Geophysical Survey Systems, Inc. 41
• If the charger remains plugged in and there are NO batteries in the charger, the charger will eventually begin to
“beep.” Since this can be annoying, it is recommend that you unplug the charger when not in use.
Appendix C: Sample Data
These examples are presented for informational use only. Conditions may be different at your site that may cause the
images to look different from the data shown here.
Example 1 – Concrete Block Data
Filled cell with rebar
Voids (2) within the
User Marks entered during collection to
identify the ends of each block (black lines)

Example 2 – Rebar Data
This is an example of rebar. Note the distance between the peaks here (as well as at the location if you marked the area) is
approximately 8 inches. Also note the approximate depth, the brightness of the hyperbolas, and they tend to be at a
constant depth over short distances.

Example 3 – Mesh Data
This is an example of mesh. Note the distance between the peaks here (as well as at the location if you marked the area) is
approximately 6 inches. Note the approximate depth and the brightness of the hyperbolas. Wire mesh depths may be more
uneven than rebar.

Example 4 – PVC
This is an example of two PVC pipes. Note that they tend to be dimmer than rebar.
