TRANSFORM YOUR SMARTPHONE INTO A SUBSURFACE IMAGING MAGNETOMETER 

This application is a system that utilizes the high-precision magnetometer sensor within your phone to assign colors to the measured uT (microTesla) values, transforming magnetic data into visual imagery. 

How does the system work? 

Our smartphones are equipped with highly sensitive magnetic sensors used for navigation (compass). Our application transforms this sensor into a scientific measurement instrument: 

Data Collection: As you walk across the field, the application measures the magnetic flux originating from the subsurface in uT (microTesla) units, dozens of times per second. 

From Data to Imagery: These collected numerical data points are processed using advanced algorithms. Even the slightest anomalies are detected, and a specific color is assigned to each coordinate. 

Visualization: Numerical data is transformed into a Heatmap, where Red tones represent ferrous metals (Positive Anomaly) and Blue tones represent underground cavities or voids (Negative Anomaly). 

Why uT (microTesla)? 

The Earth's magnetic field ranges approximately between 25 and 65 uT. Subsurface metallic objects, structures, or voids cause very subtle fluctuations in this natural field. Our application utilizes uT as the primary unit because it measures at a precision capable of capturing these micro-scale changes (anomalies) through your phone's sensor. This allows subsurface structures, invisible to the naked eye, to be converted into numerical data and meaningful imagery. 

Metals: Compress the magnetic field, increasing the uT (microTesla) value. 

Voids: Weaken the flow of the magnetic field, decreasing the uT (microTesla) value. 

Professional Analysis Advantage

You can perform real-time analysis using only your phone's sensor power, without the need for additional hardware, cables, or Bluetooth connections. 

EASE OF USE AND USER-FRIENDLY, CLEAR INTERFACE 

Complex Data, Simple Solutions: Seeing Underground Has Never Been This Easy. Unlike traditional subsurface imaging systems, our software translates even the most complex magnetic data into a visual language that anyone can understand. Regardless of your technical knowledge level, you can perform professional analyses with just a few touches. 

Why Our Interface? 

One-Touch Control: From calibration to shooting, recording to the analysis screen, all processes are designed with an intuitive flow, free from complexity. Real-Time 

Visualization: As you walk, the data doesn't just remain as numbers; it simultaneously transforms into a heat map before your eyes. The screen tells you where you need to stop. 

Smart Color Coding: We've eliminated the need for complex graph reading. Thanks to our standardized color palette, you can distinguish metallic elevations and structural voids at a glance. 

Depth at Your Fingertips: No more complex calculations on the analysis screen. Touch the point you're curious about on the map; the system will instantly provide you with the coordinates and estimated depth of that poin 

MAGPRO: OPERATING PRINCIPLES AND TECHNICAL INFRASTRUCTURE 

MagPro uses high-sensitivity magnetic sensors (magnetometers) found in modern smart devices. It is a system that detects changes in underground magnetic anomalies using a magnetometer. The program's working principle consists of three basic stages: 

1. Magnetic Data Analysis: The magnetometer measures the three-axis (X, Y, Z) strength of the magnetic field at the device's location. Anomaly Detection: Underground metallic objects, voids (tunnels, chambers, tombs), or geological layer differences cause disturbances in the Earth's natural magnetic field. 

Sensitivity (Gain): MagPro processes these micro-level disturbances with a user-adjustable multiplier (Gain Multiplier) to make them visible. 

2. Visualization and Heatmap: The collected data is placed on a grid system according to the number of steps (X) and rows (Y) specified by the user. 

Color Coding: Colors are assigned according to the intensity of magnetic values. Red/Warm 

Colors: Ferromagnetic (metallic) effects and high magnetic density. 

Blue/Cool Colors: Indicates voids, structures, or areas of low magnetic density. 

Interpolation: Gaps between data points are filled using mathematical algorithms to create a clear and understandable 2D ground image. 

3. Depth Calculation Principle (Technical Principles): The device uses an algorithm based on the Inverse Square Law between Magnetic Field Strength and Distance to calculate the depth of underground magnetic anomalies (metal, void, or mineral structures). Physical Basis: The strength of a magnetic field (uT) generated by a magnetic source decreases inversely proportionally to the cube or square of the distance from the source. The calculation logic is based on the following formula: 

Depth≈ K / (√|ΔµT| + C)

ΔµT (Anomaly Intensity): The amount of magnetic deflection at the target point. 

K (Coefficient): A constant determined according to the ground structure. 

C (Correction Constant): Sensor sensitivity margin. 

Calculation Range: Minimum 10cm, Maximum 500cm. Your sensor height setting in the settings section is included in the calculation. "The depth value calculated by the device is not a 'physical distance' measurement, but an estimate of the distance from the center of the magnetic anomaly to the sensor." 

Factors Affecting Accuracy: Magnets in the phone case, metal buckles, or metal accessories on the operator (smartwatch, metal belt buckle) directly affect the data during measurement. Heating of the phone sensor during prolonged shooting can cause drift in the values. A 'Zero' reset is necessary before each new shot. The amount of data received per second may vary depending on the phone model. A steady and slow walking speed will allow you to create the highest resolution map 

BUTTONS AND FUNCTIONS 

1-Settings: This button switches to the Settings tab. 

2-Mode Selection (Parallel & Zigzag): Informs the device of the sampling method for the area to be sampled. Two letters (P) and (Z) on the button indicate how you should sample the area. 

   Parallel Mode (P): Returns to the beginning and completes the second column when the first column ends. 

   Zigzag Mode (Z): Shifts to one side at the end of the first column and continues to the second column. You can change these modes        before the first line is full. The button function will be disabled on the second line. Adhering to the sampling method (P) or (Z)   indicated on the button is crucial for accurate results. 

3-Oscilloscope Line (Graph): Allows us to view the data from the magnetometer sensor graphically in real time. At high values, it rises from the center line and changes color from yellow to red. At low values, it shifts downwards from the center line and takes on a blue color. 

4-Instantaneous Value: You can monitor the instantaneous value in µT (MicroTesla) from the magnetometer sensor here. 

5-Status panel: This panel displays the current status. Its second function is to show the location and its numerical values when you tap on the grid map after taking a shot. 

6-Grid: The area where the heat map is generated. It creates as many stations as the number of columns (Y) and rows (X) set by the user in the settings tab. For example, if the number of columns (Y) is 10 and the number of rows (X) is 10, it will be divided into 10 x 10 = 100 stations. A sample will be taken from each station to create the heat map (grid). 

7-Color Scale/Bar: Lists the highest and lowest colors on the heat map in your shot. It's the second function that shows which color corresponds to which value. 

8-Archive/Analysis: This button takes you to the tab containing your previous recordings. This tab allows you to find previous recordings and analyze them again as if they were the first recording, as well as export the CSV file and your PDF report. 

9-Start/Stop/Sampling: In manual shooting mode, each press assigns the instantaneous value at your coordinates as a color to your heat map. In automatic shooting mode, it has a start and stop function. 

10-Calibration/Reset: Used to obtain the zero point of the field before sampling. When you press the button at the beginning of the first column before starting sampling, your device will give you a warning: "Calibration Started... Hold Device Still for Two Seconds". When calibration is complete, it will give you the instantaneous magnetic value of the ground and the amount of change (noise) in the environment. (Example: "Ground: 25.18 µT / Noise: +- 0.193 µT") 

SETTINGS TAB (SYSTEM CONFIGURATION) AUDIO & ALERTS: 

When activated, it provides audible warnings during drops and rises in the magnetic field. 

POWER MANAGEMENT: Unless activated, the application, This app does not comply with your device's battery saving protocol. If activated, the app will stop listening to sensors as soon as your device's screen turns off, thus saving battery power. 

SENSOR SENSITIVITY (GAIN): The magnetometer, the heart of the application. The sensor's sensitivity is adjusted here. It works in conjunction with the GAIN MULTIPLIER located directly below it. While the GAIN MULTIPLIER allows for coarse adjustment, the SENSOR SENSITIVITY (GAIN) allows for fine adjustment. 

AUDIOALERT THRESHOLD: Which threshold does the app's audio alert feature use? This section allows us to set the level at which the audible alert will be active. Lowering the level will trigger an audible alert in a narrower range, while raising the level will trigger an audible alert in a wider range. Paragraf metniniz 

COLOR INTENSITY: The brightness of the colors in a heat map. This is the part we adjust. The default is 100%. It can be increased up to 200%. 

MEASUREMENT & RECORD MODE: This section contains settings related to Measurement Modes and Recording. 

Manual: Allows for manual sampling at each station. 

Auto : Samples are taken automatically once per second. 

Auto-Save CSV File: When we activate this icon, every shot we take will be saved. Paragraf metniniz 

ATTENTION: If the "Auto-Save CSV File" icon is not active, your measurements will not be saved. 

Logger Mode: More detailed information about this section will be provided later. 

SHOOTING PARAMETERS 

A successful subsurface imaging process begins with the perfect alignment of your physical movements in the field with the parameters in the software. The "Settings" tab allows you to create a digital skeleton of the area you will be scanning. 

1. Scanning Area Dimensions (Grid Configuration) 

Number of Columns (Y): Indicates the total width of the area you will be scanning. Each column represents a "line" you will walk on in the field. 

Number of Rows (X): Determines the total number of steps you will take on each line. 

For example, when you select a 15x15 grid, magnetic data is collected from a total of 225 stations (points) to create a high-resolution heat map. 

2. Step Distance (cm): This parameter represents the physical distance you travel in the field for each data collection. 

Accuracy: If you are walking in 50 cm steps in the field, you must enter "50" in this section. The software calculates the actual size and location of the underground anomaly based on this data. 

3. Sensor Height (cm) Depth Calculation Factor:

 The depth algorithm automatically subtracts or adds the value you enter here to the total depth calculation when determining the distance from the surface. For the most stable results, it is recommended to hold the phone at a constant height from the ground (e.g., 10-20 cm) and enter this value in the settings 

ARCHIVES AND ANALYSIS 

Our application's Archive section is not just a repository where your field data is stored; it's also an analysis center where data is processed and transformed into professional reports. Your records are listed in an organized manner as cards with the names you assign. When you tap on any record, 5 critical options appear: 

1. ANALYSIS SCREEN (2D & 3D VISUALIZATION) 

2D Analysis Mode: 

Interactive Map: The measurement is displayed on the screen as a 2D grid. When you touch any point on the map, the precise coordinates and depth information of that point are displayed in the upper panel. . 

Importance of Numerical Values: The color palette next to the map shows the numerical values assigned to the colors. Numerical peak values are examined to distinguish real targets from false anomalies. 

Analysis Note: While the ground value averages between 0-5 µT; the sudden appearance of values of +10 and above or -10 and below indicates that the area is a real target that needs to be examined with advanced technologies. 

Smart Filtering: The filter, activated via the icon in the upper right corner, algorithmically cleans noise data. In reports received while the filter is active, this is indicated with the word "FILTERED". 

3D Visualization Mode: 

Volumetric Modeling: The map is converted into a three-dimensional surface. Positive values create sharp peaks, while negative values create deep depressions, visualizing the structure of the target. 

Control and Sensitivity: You can rotate and zoom the map using person movements; you can manually increase the anomaly sensitivity (prominence) using the slider at the bottom of the screen. 

2. CSV SHARE (EXPORT RAW DATA) This option exports the raw measurement data in CSV format. The CSV file contains X (Column), Y (Row), and Z (Magnetic Strength - µT) data. This output allows you to perform professional 3D mapping and volume calculations in world-standard geophysical software such as Golden Software Surfer or RockWare Voxler. You can also perform detailed analyses with the application's own MagPro V.4 Analysis Engine. 

3. Creating a PDF Report Our software features a professional reporting module that transforms your field results into an official document. The PDF report includes the following information: 

Visual Data: 2D Heatmap and numerically referenced color scale Field Information: Shooting date/time, step interval, and shooting area size in meters. 

Analysis Details: Target estimated depth and maximum deviation (Peak) values. System Information: Filter status (Filtered/Unfiltered), device ID, and operator-assigned custom notes. (2D Modelleme) (3D Modelleme) 

"During analysis, focus not only on colors but also on numerical values. Values that show rapid increases and sudden decreases are the strongest evidence of structural differences underground. 

SCANNING AREA (GRID) AND STATION SYSTEM 

MagPro uses a mathematical cell system called Grid to visualize field measurement data. The structure of this system is entirely shaped by the parameters the user enters in the "Settings" menu. 

1. Grid Configuration (Column and Row Logic) Your scanning area is divided into equal parts (stations) according to the Number of Columns (Y) and Number of Rows (X) values you set in the Settings tab. 

Number of Columns (Y): Represents the total number of lines (corridors) you will walk in the field. 

Number of Rows (X): Determines the total number of samples (steps) you will take on each line. 

Example: If you selected 10 Columns and 10 Rows in the settings, your scanning area will be divided into a total of 100 stations (10X10=100). Each square represents a measurement point where magnetic data will be recorded. 

2. Station and Data Collection 

Each small square on the grid is a "Station". 

Manual Sampling: When you reach each station (square), you record the value for that point by pressing the "Start" button. 

Automatic Sampling: Based on the time interval you specify, the application automatically collects magnetic data for each station as you walk. After each measurement, the station takes on the color corresponding to the magnetic field strength (uT) of that point on the color scale. 

3. Field Monitoring and Operator Location 

Grid lines help the user understand their location within the scan. By monitoring their position and the station they are at on the screen, the operator can complete the scan without errors. 

4. Resolution and Sensitivity 

Small Targets: For a more detailed map, the number of rows and columns should be reduced (15x15). The distance between stations (step length) should be reduced. 

Large Areas: To save time and perform a general scan, a lower resolution grid structure (e.g., 10x10) may be preferred. 

Technical Note: For successful subsurface imaging, it is essential that your physical steps in the field perfectly match the grid lines and station arrangement on the screen. Taking only one sample at each station ensures the most accurate heatmap. 

FIELD MEASUREMENT PROTOCOL AND SCANNING TECHNIQUES 

Scanning Methods

 Parallel Scanning (Recommended): Walking in the same direction (e.g., only North) by returning to the starting line at the end of each line. This method provides the most stable and symmetrical data. 

Zigzag Scanning: Scanning by walking one line forward and the adjacent line backward. It's faster, but requires great care in data processing because the sensor direction changes. 

CONFIGURING SCANNING PARAMETERS 

For an accurate subsurface map and depth analysis, the physical data entered into the system must perfectly match the actual field conditions. These parameters determine how the software processes the raw data into a digital coordinate system (grid). 

1. Selecting the Number of Columns (Y) and Rows (X) 

What determines the entry criteria? This is determined by the width of the area you will be scanning and the size of the target. 

Small Targets: To collect data more frequently, the number of rows/columns should be increased (e.g., 15x15), and the spacing should be reduced. 

Larger Areas: To save time, a larger grid structure (e.g., 10x10) can be chosen. 

Mathematical Equivalent: The number of columns represents the number of "lines" you will walk, and the number of rows represents the number of "steps" you will take in each line. 

2. Step Distance (cm) 

For the software to calculate the distance, it needs to know how much progress you've made in each sample. What should you enter based on? You should enter according to your physical height. 

Critical: If you are moving in 50 cm steps in the field, you must enter "50" into the system. 

Margin of Error: A 5 cm error here will cause the target to shift 1 meter on the map in a 20-step line. For the most accurate results, it is recommended to mark your shooting area beforehand. 

3. Sensor Height (cm) 

It is the vertical distance of the device (phone) from the ground during shooting. What should you enter? You should enter the value corresponding to the height at which you are holding your phone while walking (e.g., 100 cm). 

Depth Calculation Effect: The software automatically includes this height in the equation when calculating the target depth. 

Important: Maintaining this height (walking without wobbling) throughout the shot minimizes the error margin of the depth algorithm 

SIGNAL GAIN AND CALIBRATION PROTOCOL 

The efficiency of magnetic sensors depends on the balance between the magnetic noise in the environment and the signal from the target. The "Gain Control" offered in our software is the most vital parameter, determining the sensor's response threshold to magnetic changes in the environment. 

1. Magnetic Isolation (Metal Removal) Due to the principles of electromagnetic induction, ferromagnetic objects on the operator's person (smartwatches, metal buckles, mobile devices) can dominate the sensor's "near-field" data, masking the target. For accurate measurement, the operator must be free of all metal accessories. 

2. Sensor Sensitivity (Gain) and Dynamic Range Each region has a different geological magnetic background. Therefore, a flexible Gain Multiplier structure has been preferred instead of a fixed sensitivity. 

High Gain: Allows for the detection of micro-anomalies at depth, but increases the risk of "Magnetic Noise". 

Low Gain: Filters out misleading signals (noise) but may cause deeper, weak signals to disappear by remaining below the "Threshold Value". 

3. Technical Calibration Process (Step-by-Step) 

Follow this Signal Analysis Protocol to optimize your sensor for terrain conditions: 

Reference Point Determination: Stand at a point outside the shooting area that you are sure is magnetically "neutral". 

Entering Basic Settings: Set the Gain Multiplier to 8x in the settings menu. Set the Sensor Sensitivity (Fine Gain) to the medium level (50%). Static Sampling Test: Perform consecutive sampling without changing your shooting position or moving the device. 

Signal Instability (Over-Sensitivity): If random red or blue pixels appear on the map even when the device is stationary, the system is interpreting ambient magnetic noise as a signal. Solution: Gradually decrease the gain value. Signal Attenuation (Under-Sensitivity): If the map remains a completely homogeneous green background, the sensitivity threshold is too high, and micro-variations are not being detected. Solution: Increase the gain value until you see slight white/yellow transitions on the green background (natural background variation). 

Auto-Gain System 

MagPro Scan & Map features an "Intelligent Gain" engine designed to provide maximum accuracy in complex terrain conditions. This system optimizes the signal without the need for manual adjustments. Important Note: To ensure more consistent data in your Voxler and MagPro V.4 analyses, it is recommended not to adjust the gain setting along the same grid. An "Auto-Gain" calibration performed at the beginning of the scan is sufficient for the entire grid. 

Technical Summary: 

Ideal Setting: In a static position, the map remaining stable (Green) at 95% and showing only very slight density differences means "Optimized Magnetic Threshold". Critical Warning: Calibrations performed near high-voltage lines, transformers, or large metal masses (vehicles, etc.) will cause the sensor to reach its "Saturation Point" and the data to become corrupted. 

LOGGER MODE (TIME-BASED MEASUREMENT) 

Unlike the Grid mode, Logger Mode is based on time intervals. This allows for higher resolution images by utilizing faster sampling rates. In this system, coordinates are calculated entirely based on time. Whether you take 1 or 10 samples per second does not change the coordinate mapping; the system assumes a constant movement of 50 cm per second. Therefore, it is crucial to maintain a steady walking pace. Each time the "Line Return" (Line Return) button is pressed, the system records a 50 cm lateral shift to the next line.

 Example: Walking forward for 10 seconds and pressing "Line Return" 10 times results in a square survey area. Walking for 10 seconds but only pressing "Line Return" 5 times will result in a rectangular data structure. Understanding this ratio ensures high-quality data and ensures that the width (X) and length (Y) axes remain proportional in analysis engines. 

Sampling Rates & Resolution 

While higher sampling rates increase resolution for targets requiring fine detail, a standard rate of 1 sample per second is generally recommended for smoother, more stable results in typical scans. 

Software Compatibility 

Voxler & Surfer: High-speed sampling data may require manual coordinate adjustment in these programs. However, scans performed at low sampling rates are compatible without additional configuration. 

MagPro V.4: The specialized MagPro V.4 analysis engine processes all sampling speeds automatically, providing full-detail analysis without extra settings. 

How to Activate Navigate to Settings and toggle the "Precision Logger Mode" switch. Use the "Recording Speed" seek bar to adjust the samples per second. Tap "Save Settings" to enter the Logger interface. 

Note: For the most accurate 3D modeling, ensure your physical steps match the 50 cm/second calibration as closely as possible.

 Navigation to Logger Screen Once the "Precision Logger Mode" is enabled in the Settings and you tap "Save Settings," the application will automatically redirect you to the Logger interface. 

Under standing the Logger Interface On the Logger screen, you will find the Analog Gauge, Oscilloscope Graph, and Digital Values. Below these displays, there are four primary control button. 

Reset (Zeroing): Before starting any scan, you must press this button. The system calibrates the current ambient magnetic values as the "ground zero" point. Failure to reset at the start of each session may result in inaccurate data offsets. 

Start Scan: This button initiates the data recording. During an active session, it also functions as a Pause and Resume toggle. 

Line Return: Use this button to notify the system that you have completed a path and are moving to the next parallel line. When pressed, the system automatically pauses recording for 2 seconds, allowing you enough time to reposition yourself on the next line. Recording resumes automatically after the countdown. 

Save: Once your survey is complete, use this button to stop the process and save the data file to your device. 

Managing Logger Recordings

To access the data files captured in this mode: Tap the Folder Icon located in the top-right corner of the Logger screen. Within this menu, you can view your CSV recordings. You have the options to Rename, Delete, or Export these files in CSV format for external analysis.

• Remote Scan Management: You can completely control and manage your ground scanning steps directly from your computer terminal.

• Dual-Screen Visualization: Monitor raw magnetic field fluctuations simultaneously through the live mobile oscilloscope and the high-resolution desktop interface displaying real-time microTesla ($\mu T$) numerical values.

• Dynamic Grid Mapping: The 2D and 3D visualization grids on your PC software are structurally shaped by the precise X (Width) and Y (Size) dimensions you configured in your mobile settings, ensuring centimeter-level anomaly mapping in the field.

⚠️ CRITICAL FIELD NOTE: Before initiating any matrix scan or logging sequence, always perform a "Tare/Zero Reset" close to the ground surface to calibrate the internal magnetometer sensor against localized soil mineralization.

BLUETOOTH SHUTTER COMPATIBILITY 

MagPro is compatible with standard Bluetooth camera shutters found on most selfie sticks (monopods). This feature allows you to perform scans with maximum precision without needing to touch the phone screen, ensuring total stability during data collection. 

Grid-Based Scanning with Bluetooth Shutter After configuring your grid settings (steps, step spacing, etc.), enable Bluetooth and pair your shutter. Secure your phone to the selfie stick and extend it downward by your side, ensuring the screen is visible to you. 

Zeroing (Reset): Press the shutter button twice in rapid succession to perform a reset. You will hear a long, intermittent beep. Sampling: Each single press takes one sample. You will hear a single short beep. 

Logger Mode (Time-Based) with Bluetooth Shutter

 Once "Precision Logger Mode" is activated in the settings and Bluetooth is connected, use the shutter to control the timeline: 

Zeroing (Reset): Press the shutter button 4 times consecutively to reset the system. 

Line Return: Press the shutter button twice to trigger a line transition. 

Start/Pause: A single press activates or pauses the recording. 

Saving: When the scan is complete, use the "Save" button on the application screen to store your data. 

Pro Tip for Deep Targets 

While we recommend using the selfie stick for all scans to maintain stability, it is essential for detecting small or deeply buried targets. Holding the sensor (phone) as close to the ground as possible significantly increases the probability of success and provides much clearer anomaly detection 

ANALYSIS DETAILS 

MagPro Scan& Map transforms raw magnetic data collected from the field into not just an image, but an interpretable engineering output. 

2D High Resolution Heat Map (Heatmap)

When a scan is completed or a file is opened from the archive, the application automatically processes the data on a 2D surface. The 2D Heat Map is the main analysis screen of the MagPro application. This screen presents underground magnetic field variations in a bird's-eye (plan) view on a colored grid system. 

A. Color Scale and Meanings 

The application considers the Earth's normal magnetic field value as the "0" point (baseline). Deviations from this baseline are represented by two primary colors: 

Red and Its Tones (Positive Anomalies): Indicates areas where the magnetic field is stronger than normal. 

Targets: Ferromagnetic metals such as iron, steel, nickel; furnaces, burnt brick structures and ancient hearths. 

Appearance: Generally appears as sharp, bright red focal points on the map. 

Blue and Its Tones (Negative Anomalies): Indicates areas where the magnetic field is weaker than normal. 

Targets: Underground voids, tunnels, burial chambers, cellars, or non-magnetic fill areas. 

Appearance: Observed as diffuse or linear (tunnel-like) dark blue areas. 

Green and Yellow Tones (Neutral Areas): Represent the stable ground structure of the magnetic field, free from anomalies, within its natural ground value. 

B. Coordinate-Based Targeting (X and Y Axis) 

The heat map is scaled according to the Step Size and Row Spacing you set during the scan.

Interactive Tracking: When you tap any cell on the map, the distance of that point from the starting point (e.g.: X: 2.5m, Y: 4.0m) appears at the top of the screen. 

Blue and Its Tones (Negative Anomalies): Indicates areas where the magnetic field is weaker than normal. 

Red and Its Tones (Positive Anomalies): Indicates areas where the magnetic field is stronger than normal. 

Green and Yellow Tones (Neutral Areas): Represents stable soil structure at the natural ground value of the magnetic field, containing no anomalies. 

3D ANALYSIS AND VOLUMETRIC VISUALIZATION

 MagPro features an advanced 3D modeling engine that carries the anomalies detected in the 2D heat map to a third dimension (Z axis), allowing you to better understand the physical form of underground structures. 

Z Axis and Magnetic Amplitude Logic 

In 3D analysis mode, magnetic intensity (nT) values are converted into vertical height data. 

Positive Peaks: Points where the magnetic field increases (Red zones) form upward rising peaks on the model. This typically represents metallic masses or dense mineral structures. 

Negative Sinks: Points where the magnetic field decreases (Blue zones) form downward deepening depressions on the model. This usually indicates void structures such as tunnels, cellars, or burial chambers. 

Interactive Navigation 

You can have full control over the 3D model with finger gestures. 

Rotate: You can rotate the model 360 degrees to view the anomaly from different angles and determine the orientation of the structure.

 Scaling: If the magnetic amplitude is very low, you can increase the vertical scale to make ambiguous anomalies more visible and distinct. 

Structural Form Analysis 

3D modeling is your greatest aid in distinguishing the type of target. 

Point Spikes: Generally indicates small, near-surface, high magnetic value metal objects (nails, scrap metal, etc.). 

Wide and Regular Blocks: Highly likely to represent room foundations, wall remnants, or enclosed areas with regular geometry underground. 

Depth Perception 

The width and steepness of the fluctuation on the 3D graph provides clues about the object's depth. Wide-based anomalies with smooth transitions generally indicate deeper masses, while sharp and narrow-based anomalies point to near-surface objects 

ADVANCED DATA ANALYSIS WITH VOXLER AND SURFER (CSV INTEGRATION) 

MagPro is designed to make the best use of your limited time in the field. However, after fieldwork is complete, it offers professional software support for much deeper, higher-resolution, and detailed examination of the collected data. 

"Micro anomalies and complex structural forms that cannot be fully selected on the application screen can be analyzed down to the finest detail thanks to desktop software." 

5-Column Professional Data Structure and Analysis 

MagPro records field data not just as an image, but as a digital dataset in 5 different dimensions. This structure offers unlimited depth when analyzing in professional software such as Surfer and Voxler. 

CSV File Architecture (5 Critical Columns)

1- X Column (Horizontal Coordinate): Your column number in the scan area (e.g.: 0, 1, 2...). 

2- Y Column (Vertical Coordinate): Your row number in the scan area (e.g.: 0, 1, 2...) 

3- Z Column (Raw Magnetic Intensity - nT): Total magnetic flux intensity from underground. The main source of 2D and 3D maps. 

4- V Column (Vectorial Component): Represents the vertical component of the magnetic field. Used to verify the object's angle to center and exact position. 

5-Grad (Gradient): The rate of change between two adjacent points. The most valuable data in analysis. 

Why Important? Gradient data cleans broad magnetic noise and highlights only the sharp outlines of underground structures (wall corners, metal boundaries, tunnel entrances) 

AUTOMATIC DATA MATCHING AND ANALYSIS OPTIONS 

CSV files produced by MagPro V3 are fully compatible with Voxler's advanced data recognition architecture. In most cases, Voxler automatically assigns Column E: Grad data as the main analysis variable when you import your file. 

Smart Data Integration with Voxler 

MagPro's data architecture is fully compatible with Voxler. When you import your file into Voxler, the system offers an intelligent automatic configuration: 

Automatic Column Matching (Gridder)

Voxler automatically reads the headers in the CSV file. When you open the "Gridder" settings, you will see: 

X and Y Data: The software automatically recognizes the coordinates. 

Column D (V) - Full Compatibility Mode (Recommended) 

Voxler usually selects this column automatically. It is the exact equivalent of the 2D/3D image on the phone screen. 

Feature: Based on the vertical component (V) of the magnetic field. 

Result: Presents both Red (Positive/Metal) and Blue (Negative/Void) anomalies simultaneously, with the same color balance as the application screen. It is the ideal column for viewing the overall underground structure (room + metal inside) as a whole. 

Column E (Grad) - Positive Anomaly Sharpness Mode 

If you select only this column in Voxler, the image changes radically. 

Feature: Focuses on the rate of magnetic change (Gradient). 

Result: In this mode, "void" (blue) effects are generally minimized or disappear. However, underground metals, hard structural corners, and very sharp magnetic transitions virtually glow. 

Use Case: "I know there is a room (void) here, but where exactly is the metal inside?" - switch to this column for the answer. 

"To preserve the famous blue/red balance and room forms from the application screen in Voxler, use Column D (V) data. If your goal is to filter out voids and focus only on the strongest magnetic focal points (metals), you can manually switch to Column E (Grad) in the Gridder settings." 

ANALYZING MAGNETIC DATA WITH INSTALLED ANALYSIS ENGINES ON YOUR PC 

MagPro V.4 MagPro V.4 is an analysis engine adapted for PC that works in full integration with your MagPro Scan & Map Android application. You can export the data collected via the MagPro Scan & Map Android app in CSV format and perform detailed analyses using the MagPro V.4 Analysis Engine. 

Accessing MagPro V.4: Open the "Settings" tab within the application. At the bottom of the tab, locate the button labeled "Get MagPro V.4 PC Version." Upon clicking the button, the app will generate a unique code for you in the format "MP-5463-0EDR." You can then share this code and the download link with your computer. The link sent to your computer will direct you to the "MagPro V.4 Analysis Engine" section on www.magpro.tr. By entering your code into the license field, you can download and install the MagPro V.4 Analysis Engine on your PC. 

Note: Detailed download and installation instructions are available on the website. 

How to Use? 

Launch the Software: Open the MagPro V.4 application after completing the installation on your PC. 

Import Data: Use the "OPEN CSV" button to import the data exported from your mobile application in CSV format. 

Automatic Visualization: The program will instantly process the CSV file, color-coding the magnetic values to generate both 2D and 3D maps. 

Analysis and Navigation 

Target Data: When you hover over the map with your cursor, the Target Coordinates, Target Magnetic Value, and Estimated Depth information will appear in a red-bordered box next to the map. Sensitivity Adjustment (SEEK BARS): Use the two seek bars located below the map to focus on either voids or metallic targets. These allow you to increase or decrease sensitivity as needed. ISOSURFACE: Use the ISOSURFACE button for a multi-dimensional inspection, providing detailed insights into the shapes and structures of deep targets. 

2D FOCUS: This button opens a 2D map in a separate window. It allows you to refine targets by shifting focus—redirecting toward negative anomalies if your CSV contains general positive ones, or vice versa. 

Reporting and Customization 

Professional Reports: Generate professional reports with a single click using the REPORT button. Reports are saved in PNG format and automatically stored in a folder titled "MagPro Analysis Reports" on your desktop. 

Custom Branding (LOGO): Use the LOGO button to add your own company logo and business name to the generated reports. 

Color Themes: Change the visual appearance of the maps using the CHANGE COLOR button. 

Advanced Settings 

SOIL CALIBRATION: The SOIL button serves as a depth calibration tool for the area you surveyed. It offers four options: Sand, Normal, Clay, and Mineralized Soil. Selecting the correct soil type ensures more accurate depth estimations. 

Voxler Integration: Voxler instantly recognizes the CSV files generated by your MagPro Scan&Map application. You can import and analyze your CSV files in Voxler without any additional configuration.
