Gold Star 3D Scanner

The new Long-Range Locator technology incorporated into Gold Star 3D Scanner through a new powerful detection probe called Intelligent Multi Transceiver Unit or I.M.T.U
I.M.T.U generate a high-frequency wave signals in search direction, these waves intersect with the signals of magnetic fields released from buried metal targets, then reflected signals are received through a pair of antennas, these received signals are converted into digital signals inside main unit of device and analyzed and visualized on screen.

In MANUAL LRL system, many of scan settings can be adjusted manually by the user according to his preferences before starting the long-range scan, here are the available settings:

• Target

User can choose here the target type, or a type of metal the target is made of, he can choose from preset search programs that include all types of ferrous and non-ferrous metals including:
Gold Treasure- Gold Ore – Silver – Copper – Platinum – Bronze – Iron – Diamond – Gemstones – Gold Veins – Cavity

• Distance

The distance value reflects the scanning field in the forward direction, this value can be set within a range between 0 – 3000 meters from pre-set values:
250 – 500 – 750 – 1000 – 1250 – 1500 – 1750 – 2000 – 2250 – 2500 – 2750 – 3000 m

• Depth

It is the value of the maximum search depth that can be reached using the current search settings, and the value can be set precisely within the range from 0 to 50 meters.

After adjusting the previous search settings, the screen displays a summary of selected settings and user can press (Start Scan) button to start actual scan process.

Result screen display in upper-left corner a digital compass, containing an indicator indicating the geographic direction of the device (for example, towards the north).

In middle of screen there is semi-circle graded scale with direction angle values , zero degree in center and a range of 0-90 degrees in both left and right, an arrow-shaped indicator pointing to specific angle value the represents the direction of movement of the antennas according to the user’s movement when searching.

On the right of result screen Inclination Indicator, this indicator is an important feature allow the user to accurately and correctly adjust the angle of inclination of the device from the horizon, the values with green color – in middle – indicates the correct values, on the other hand the values with red color indicates the wrong values of the inclination angle during scan.

AUTO LRL search system uses I.M.T.U and long-range antennas to search for signals of potential targets within the long-range scan field.

It is advanced search system that covers large areas in open fields of the determined area, this system has the ability to identify all types of buried metals by analyzing captured signals.

Here the user can adjust following settings:

• Distance

It is the distance in front-range (forward direction), can be set in 0 – 3000 m range as explained before in Manual LRL system.

• Depth

It is the maximum depth of possible targets that the device can reach to find potential targets, its value can be set in 0 – 50 m range also like before.

After selecting of previous settings, the user can start the search process, and during search the antennas will move left or right depending on possible nearby targets, a visual indicator on screen will guide the user as it displays a left or right progress bar with gradient colors from green (minimum) to red (maximum value) based on target position.

The user must track the movement of antennas tell he got a best signal and after finishing he can move to “Report” screen that will display a visual report about possible target as four horizontal bars (gold – silver – iron – diamond), every bar will display an estimated percentage value that indicate probability of target composition.

CTRL LRL system is one of the new technologies and important features that have been integrated into Gold Star 3D Scanner, that enables the user to set the exact value of the search frequency in order to search for a specific type of metal or alloy of metals based on specific frequency value and thus ensure more accurate results when searching.

In this system, user can set many search-related settings including:

• Soil Type

It is the type of soil of the ground in scan field, can be set to one of following types:
Rock – Mixed – Neutral – Clay – Metallic – Sandy – Mineral – Chalky – Salty

• Frequency

It is the custom frequency the user can set manually using this option.
Values range in the 250-5000 MHz range, and can be set from predefined values like 250 – 500 – 750 …. 5000 MHz

• Distance

It is the maximum distance between user location and the target position during the scan process. It means that user can search custom circular distance around himself and this distance start from 0 to 3000 m and can be set like in previous systems.

• Depth

It is maximum depth of possible targets that the device can reach to find, its value can be set in 0 – 50 m range as explained previously.

After adjusting all of previous settings the user moves to scan screen and press “Start Scan” button to begin the search process.
The results screen will display a circular indicator, the direction arrow reflects the direction of antennas in degrees, on the right the inclination indicator that explained previously.

Ionic system uses a new developed technology incorporated into a new probe named Intelligent Multi Transceiver Unit or I.M.T.U.
The I.M.T.U technology is the first of its kind in metal detectors, and it constitutes a major development from the traditional ionic fields detection system found in previous Mega Detection devices or competing devices.

The new technology allows more accurate detection of ionic fields resulting from metallic targets buried under the ground thanks to I.M.T.U that ensures accurate receiving and processing of coming signals, with the ability to control some signal settings on the screen for more accurate results.

After selecting the ionic system, the device will start searching directly, here are the possible settings that can be adjusted by the user:

• Sensitivity

During the search process and according to the target scanning, the ionic system
will generate variable audio tone, it represents the target ability or the distance between user and the target.
The user can change the value of signal sensitivity to analyze the output sound, its value range is between 0 and 100, the selected value shown on Sensitivity circular scale.

• Gain

It is the signal gain or in other words signal strength, the user can control the signal strength using this setting, and it presented as percentage value (0-100) on circular scale like sensitivity.

Generally, it is recommended to reduce this value for detecting of large-size targets, and increase gain value for small-size targets detection.

In the middle of the screen there is a circular indicator, in the center of it there is a circle whose diameter and color change according to the received signal and the distance of the target from the location of the device, where it shrinks and expands with changing color to one of the following colors (red, blue or green) depending on the type of target.

Based on the received signal, the device also makes an audio tone with pitch and strength related to the position of the target and the nature of the signal.

Bionic system is similar to the Ionic system in terms of how it is work and use of Intelligent Multi Transceiver Unit (I.M.T.U) to perform the scan process.
But the difference is that here, ionic signals are captured from a particular metal object. for example, from golden ring or coin, and then the search is directed towards capturing ionic signals similar to metal objects buried underground within the surrounding area.

That mean in the ionic search system, the search is random and free, but in the bionic system the search is directed according to predefined signals.

After selecting the Bionic system and pointing the I.M.T.U to specific target made of the metal that will be searched, the device will start scan for ionic fields in direction of user movement and there are same options as in Ionic system can be adjusted:

• Sensitivity

The user can change the value of signal sensitivity to analyze the output sound, its value range is between 0 and 100, the selected value shown on Sensitivity circular scale.

• Gain

It is the signal gain or in other words signal strength, the user can control the signal strength using this setting, and it presented as percentage value (0-100) on circular scale like sensitivity.

The previous values presented in result screen as circular percentage indicators on right and left sides similar to indicators in Ionic system.
Here there is also a Signal Power or strength indicator displayed below presented as variable-length bars with variable colors and heights based on received signal.

In the center of the screen there is a circular indicator whose movement and colors change according to the type of target and the signal captured with three color possibilities, which are green, red, and blue, related to the type of target.

Based on the received signal, the device also makes an audio tone with pitch and strength related to the position of the target and signal strength.

Live Stream is a system developed to detect various ferrous and non-ferrous metals
in the real time, in form of a live transmission with a visual representation of received signal as specific color stream that reflects the type of the target.

For example: precious metal like gold or bronze – ferrous metal like iron – cavities such as tunnel.
The process of measuring signals or scanning process is carried out by a Vertical High Signal Transceiver (V.S.T) probe, which is a special developed probe, at the end of it there is a quadrilateral cone on both sides of cone there is a set of LEDs that change its colors according to the type of the target , for example the LEDs will emit a red light if the targets is a golden object or blue if it is a tunnel.

The signals captured by V.S.T after calibration represented on the device screen as continuous color stream that changes its color according to the type of possible target , similarly the color is Red when capturing a precious metal signal and green for normal ground , a numeric value related to the target displayed on screen beside the color stream.
In conjunction with the color indicator the device will generate audio tones based on the target type whose signal is captured.

Also, the user can see a visual representation of the signals on the bundled tablet that came with the device within Mega Detection Multi Visual Analyzer app that displays the signal scheme in a graph and the color of the graph will change in a similar way depending on the nature of the signal in other words the type of metal or target.

This powerful search system is a new system with completely new technology designed and developed especially for Mega Detection devices with latest technologies in 3D ground scanning technologies.

This 3D ground scan technology uses a new powerful and unique probe called Multi Ground Scanner (M.G.S) with four built-in sensors and large surface area offering more coverage of ground during scan and reduce the time and effort of scanning large areas quickly with more accurate results.

3D Ground Scan system helps the user to scan the ground and create visual representation on both the device screen or bundled tablet. this system can make searching and find burials and artifacts and even cavities under the ground easy to the user with greater speed and more accuracy.

The settings that can be adjusted on device screen:

• Result Display

The user can select one of two options:

1. Device: in this case a scan results will be presented visually on device screen
2. Tablet: the scan results will be presented visually on bundled tablet screen using Multi Visual Analyzer app.

• Mode

It is the method of performing the scan procedure and can be set to:

1. Manual: here the user will record the measurement of signals in every scan point manually.
2. Automatic: in this case the device will record the measurements of every scan point automatically.

• Path

Path value present how user will move in search are to complete the scan process and there are two options:

1. One Direction: in one-direction scan the user will move and record the measurements in every point in a scan line and at end of every line, he will return to near the start of previous line but with offset distance to start scanning another line and so on. That mean the direction of scan will be in one direction on every line or all scan lines will be parallel to each other.
2. Zig Zag: in this case the start point of next search line is near the end point of previous line or in other words the direction of movement will be opposite for each consecutive lines.

• Size

Here user can set following settings:

1. Width: it presents the number of scan lines and can be set to desired value using arrows controls in control panel.
2. Height: it is the number of points in every scan line or scan points , it can be set like previous value.

• Start Point

User can set the point in search area (rectangular area that include scan lines and points) where the scan procedure will begin.

1. Left: in this case the scan process begins from bottom – left corner of search area
2. Right: the scan process will begin from bottom – right corner of search area

After settings of all previous setting the Scan tab will display a summary of previous selected settings and user can press OK on device control panel to start the scan process.

During the scan process the measurement in every scan point will be presented visually on screen on 2D grid consisting of number of rows (scan points) and columns (scan lines) of cells and every cell presented in specific color that reflect the structure of related ground area.

The table below show the type of ground related to each color:

On the right side of 2D grid there are many values presented:

current x (current scan line number) – current y (current scan point) – search value

After completing the scan in every scan line and point, the scan data can be saved as a file to the device memory for later analysis.

In case that user choose to complete the scan via the tablet, the same settings are set within the Multi Visual Analyzer app installed on tablet, and the scanning is performed by the device in the same way, and the results are displayed directly inside the app in the form of a three-dimensional graphics based on structure of the scanned ground and what it contains of different target types that presented in different colors like in the previous table.

Multi Visual Analyzer app gives the user a more accurate possibility to illustrate and know the buried targets, their type, depth and exact position within the scanned area via its powerful analysis tools.

This system is used to determine the presence of a metal target or cavity with the precise location in which the buried metal or cavity is located via an audio or visual feedback presented on the screen, the process of scanning for possible targets is performed via the V.S.T probe.

In the result screen of this system there are many options:

• Sensitivity

During the search process and according to the target scanning, the pin pointer system will make special scan sound with specific tone and the visual graph on the screen presents the target presence under the ground.

The user can change the value of sensitivity at any time to be able to analyze the output

sound and the accompanied graph.

The value can be set in 0 – 10 range.

• Calibration

User can use this option to calibrate the sensor sensitivity at any time according to the ground type and terrain.

• Reset

Reset the calibration process to default value.

The visual representation of received signals on device screen is a curved bar graph based on type of the target.

For example, in case of receiving metal signals the bar graph will be consisted of rectangles facing upward, of different length, with graded colors from green to red in the center at the maximum values, and then graded towards green with low values.

In the case of receiving cavity signals – such as a tunnel – it will be made of rectangles facing downwards, of different length, ranging from green to dark blue in the middle at the maximum values, and then graded towards green at lower values.
