SEARCH MODES - 3D GROUND SCAN
3D Ground scanning allows you to create 3D graphs based on
whether you scan a specific area. There are two options in the
ground scanning function: Automatic and Manual. You do not
need to press any button in automatic scanning for each num-
ber of signal pulses entered, and you need to press the start
button for each signal in manual scanning.

| 9 |
PRE-SCAN SETTINGS IN AUTO & MANUAL SCAN
When you select Automatic ground Scan, you will be directed
to the settings you need to make before the search.
Measurement Type: You must choose the number of steps or
meters. In the step option, you have to enter step numbers in
step and line options. For example, 5 steps, 5 rows.
In the Meter option, you must enter in meters in step and line
options. For example, 5 meters line, 5 meters row.
Zigzag Parallel
Scanning Type: You can scan in parallel or zigzag. You should
start scanning from the start point and finish at the endpoint,
as shown in the graph. When the number of signal pulses en-
tered for each row is complete, you should proceed to the next
scan row. The measuring tool should not be turned when you
move to the next row.

| 10 |
Line Step
Line: You must enter the row size of the search area in meters
or steps according to the unit you have selected in the "Meas-
urement type" section. Depending on the number of signal
pulses you have entered, you should go to the next scan row
when the signal pulses are over.
Step: You must enter the row size of the search area in meters
or steps according to the unit you have selected in the "Meas-
urement type" section.
Target Type: You can select three different search objectives:
Small, General and Tunnel according to the purpose of your
screening. Small should be selected if your target is small ob-
jects. In the Small option, each scan signal range should be 15-
20 cm. You can select the General scan, such as normal object,
space, structure. In this option, your scan signal range should
be between 25 and 35 cm. You can select the Tunnel option
for your scans covering large areas such as tunnel, room, and
grave. In this option you can search at 50 cm intervals.
For example; If you select 10 signal steps and select small as
the target type you will scan with a distance of 30 cm each;
You will have created a scanning line of 300 cm or 3 meters.

| 11 |
0.8 –4 seconds
Step Duration: If you want the device to wait between each
signal pulse, you can select not less than 0.8 seconds. When
you increase the time, the waiting time will increase. This fea-
ture is activated in the automatic search option.
Left Right
Starting Point: You can adjust your scanning starting point by
starting at the bottom right or bottom left corner. To do this,
you must select left or right from the starting point. If you start
searching from the bottom left corner, you should continue
with the next scan row on your right. If your selection is in the
bottom right corner, you should continue with your next scan
row on your left.
After you have made all the settings, you can start scanning by
pressing the Confirm button.

| 12 |
AUTO & MANUAL 3D SCAN
Depending on the settings you made before the search, the 3D
Ground scan will begin. During scanning, you will see colors
such as green, red, yellow, and blue, depending on the meas-
urements you have taken. All metallic objects and objects
with high magnetic effect are mostly red, some are orange,
Underground cavities, filled soils, cavities are blue, you can see
the soil as green without any changes and anomalies. You can
see mineral soils and objects with a relatively low magnetic ef-
fect as yellow and orange. After the scan, you can examine this
data in detail on the analysis screen.
On the right side of the scan screen, you will see the settings
you made before scanning. If your selection is Automatic
mode, you will be directed to press the Start button when the
number of signal steps entered for each sequence is complete.
You must do this for each scan line.
If your selection is Manual Mode, you must press the start but-
ton on the front handle for each signal step.

| 13 |
When the number of signal steps and lines entered is com-
plete, the device will automatically exit the search function
and direct you to the 3D Viewer function fora detailed analysis
of the received data.
If you want to end the search before the number of signal
steps entered and the line row is completed, you must press
the Back button on the device. Press Back and the device will
ask you if you want to end the search. Select Yes and your
search will end and you will be directed to the 3D Viewer

| 14 |
screen. If you select No, you can continue your search from
where you left off.
To obtain regular and accurate data, you must complete the
number of signal steps and the number of lines entered.
3D MONITOR AND GRAPHICAL ANALYSIS
Your device will direct you to this screen after scanning so you
can examine the graphics you have obtained with 3-Dimen-
sional Ground Scanning in detail. On this screen, you will see
3D graphics of the data you have collected in the center.
The color bar on the right gives information about the soil that
was scanned.
Functions of the buttons in 3D Viewer:
Mode: Switches between different types of analysis.
Arrow buttons: Turn the graph up, down, left and right; move
the graph and go through each square in the details page.
Zoom: Makes the graph bigger or smaller to examine in detail.
OK: Turns on and off the grid on the graph. Squares on this
grid correspond to each of your search signals.
Back: Allows to go back to the main screen from 3D Viewer
function.

| 15 |
Start: Allows to go back to the main screen from 3D Viewer
function. This view allows you to analyze the data in more de-
tailed lines.
There are 4 different graph analysis features on the 3D
Viewer function.
3D Rotation: You can
use the direction but-
tons on the device to ro-
tate your graph left-
right and up-down. This
way, you can see your
graphic from different
angles. You can use the
magnifier buttons to zoom in and zoom out to the graphic. You
can zoom in with the button that has a plus sign and zoom out
with the button that has a minus sign.
3D Pan: You can exam-
ine your graph and the
colors closely by zoom-
ing in. You can move
the graph left and
right, up and down
with the direction but-
tons and go through
the graph.

| 16 |
Scanning Details: You
can see numerical val-
ues of your data and get
information about
depth by choosing type
of soil. You can go
around the graph with
direction buttons and
examine the point details.
Depth Information: You
can find out the general
depth information of
the measurement and
see the start and end
points of ground and
other variables.
The colors on the graph represent the following;
•Red: Metallic objects and objects with high magnetic
effect,
•Blue: Filled dirt, tunnels and cavities in the under-
ground.
•Green: Standard soil that does not have any mag-
netic effects.
•Orange and Yellow: Mineral substances, mineral
soil and objects that have relatively low magnetic ef-
fect.

DETECTION & METAL-MINERAL
DIFFERENTIATION
Metal Mineral
•Metallic objects have a distinct shape, while minerals
usually have a messy and scattered appearance.
•Metallic objects have red color, mineral substances are
usually yellow and orange.
•The most important property of metallic objects that dis-
tinguishes them from minerals is that there is a signifi-
cant numerical difference between them and soil in the
collected data.
In order to see these numerical values, you have to switch to
the Scanning Details feature in the 3D Viewer function. You
can see soil balance value and numerical values of the selected
area in the top bar when you go around the graph with direc-
tion buttons.

| 18 |
1- Soil Type
2- Ground Balance
Value
3- Signal Value
4- Signal Depth
There must be an in-
crease of at least 15
units between the soil, which is shown with green on the
graph, and metallic objects which are shown with red. For ex-
ample, if the level of soil is 150, there should be a numerical
value of at least 165-170 in order to be a metallic object pre-
sent. If there is a difference of a couple of units, this data indi-
cates mineral. A few units of increase are also possible for new
objects that have less magnetic effect and have not been un-
derground for too long.
If there is a big difference between the soil and object that has
magnetic effect, there is a great possibility of valueless metal.
For example, when the level of soil is 80 units and magnetic
object is 200 units.
Metallic objects that have been buried underground for a
longer period of time can be detected more easily. Precious
materials such as gold or silver can be detected only if they
were buried together with objects that have high magnetic ef-
fect. In order to see whether the data represents a real object
or not, more than one measurement should be performed in
the same spot and all of them should result similarly.

| 19 |
CAVITY DETECTION
Tunnel Grave
Artificially created underground cavities such as tunnels,
chambers, tombs are seen as blue color in the graphic. In the
event of any dents or soil filled in the underground, the data
will be light blue, turquoise or light green.
What you are searching for must have a distinctive shape and
form, for example if you are searching for a structure that re-
sembles a tomb, the blue area on the graph should be rectan-
gular and the size of a tomb.
In order to see this numerical value, you should switch to the
Scanning Details feature in 3D viewer function.
There must be a decrease of at least 15 points between the
soil which is shown with green and grounds which are shown
with blue. For example, if soil level is 150, then the grounds
should have a value of 135-130.
