Introduction
We are the first great detectors company in the world in the field of
manufacturing and selling gold prospecting devices, burials and precious
treasures We started our work since 2012 in the manufacture and sale of
hardware products specialized in the search for minerals, gold and

3D Ground Scan
3D Ground Scan
The 3D ground scan system in the GRT device uses the latest technology to send
and receive signals in the device direction and using a 3D analyzer is able to
draw a 3D diagram of possible objects in the underground.
How to use
After completing the connections and opening the application and selecting 3D
scan system, you will see a page where you have to set the soil type, number
of steps, number of scan lines and type of moving direction before searching
.
Set the above setting and press on Start to open scan page
Then stand in the desired location and place the device perpendicular to the ground at a distance of 5 to 10 cm from the ground. Depending on the Android screen, press the scan button on the device once with each step (with mini-mum one second between each pressing). And wait for the result of each scan to appear on the screen.
Note: If you do not see a change in the display after pressing the scan
button, press the scan button again without taking the next step.
Continue until you reach the end of the line, then move on to the next line
and start the scan again.
Note: for better and exact resault you have to press on start exactly
every 30 cm per each step.
Note: If you have selected the zigzag mode, you must do the scan in a
zigzag pattern, and if you have selected the parallel mode, the scan must be
done in parallel pattern.
Diagram analysis
The output diagram by the 3D scanning system has a range of different colors, which are described below:
- Blue: If there is any underground tunnel or hole, the color of the graph will change to blue.
- Light blue: If there is any tunnel or hole in a small distance from the device, the color of the graph will change to light blue.
- Green: This color represents a com-pletely ordinary earth without any potential minerals or treasures.
- Yellow or Portuguese: If there is any non-precious metal or a small earth size meaning, the color of the graph will change to yellow or Portuguese.
- Red: If there is treasure or precious metals below the scanned area, the color of the graph will change to this color.
Diagram with 3 different colors sample
Scanned tiles
All scanned diagrams will be saved saved automatically after closing 3D scan screen.
To re-view the file (s), the user can click on the file icon on the right side
of the scan screen. a list will open which includes all previously scanned
files.
Note: By long click on each file in the file list, a message will appear
that allows the user to delete the file.
3D Screen Controlers
-
Screen reset
Use this icon to reset the diagram on the screen on top view -
Diagram Setting
user can use this option to change the appearance of the 3D diagram or its color. Clicking on this icon will open a sliding window that has the following options:-
Red compress:
By increasing and decreasing the red slider bar, you can increase or decrease the intensity of the red color density in the chart. -
Blue compress:
By increasing and decreasing the blue slider bar, you can increase or decrease the intensity of the blue color density in the chart.
-
-
Reset:
By clicking on this option, the above color settings can be reset to the default. -
Grid mode:
By clicking on this option, the shape of the graph changes from a surface mode to a network mode. Clicking again on this option will change the shape of the chart to flat again. -
Colors Filter: Using these three color buttons, you can remove or re-add the desired color from the diagram. This option is used to better detect the desired colors in complex scans.
Point Locating
Using these options, you can point to a specific feature and check the depth of
that point.
X + and X-: to control the location of the line perpendicular on the surface.
Y + and Y-: Used to control the location of the horizontal line on the surface
Z + and Z-: Used to control the location of vertical and horizontal lines on
surfac-es for depth mesuring depth.
use this icon to open a view which includes four different parameters on the
screen.
- Value: shows the each scan value while scanning.
- Deep: shows the deep of the locatd point on the diagram.
- Level: shows the level value (cm)
- Step: shows the step value (cm)

Discromination
This system determines whether the burial is valuable or worthless by sending and receiving pulses through the device sensor and analyzing the received pulses. It is recommended to use this system when excavating the burial through a 3D scanning system and to ensure the value of the burial before excavation.
How to use
After discovering the tomb and determining its approximate point by the 3D
scanning system, enter this system through the main menu on the Android
device. by selecting this item a black and empty window will open that Notices
“press on start”.
Position the device perpendicular to the desired point and press the Scan
button on the device (press and hold). Then start moving slowly and in one
direction. A graph is displayed on the screen of the Android device, which can
be analyzed to determine the buried value.
Below are examples of different diagrams.
Note: The Distance between the probe head and the surface of the earth must be
5 to 10 cm
Sound analyzer
Refer to the figure to analyze the numbers displayed by the device.
If the displayed number is 0 or numbers close to it, it means normal ground
without any tombs or cavities.
The number is below zero and close to -200, which means that there are
cavities underground.
A number above zero indicates the possibility of Ferrous or Non-Ferrous metals
being available. If the number reaches 150, this means that there is a
Ferrousmetal.
If the number is higher than 150 and close to 200, this indicates the Non-
Ferrous metals metals such as gold or copper.
