AJAX GAMMA 3D Gold, Metal and Underground Cavity Detector
The AJAX GAMMA is a professional multi-system detector designed for searching for gold, precious metals, buried treasures, underground cavities, caves, archaeological targets, pipes, wires, and other subsurface objects.
GAMMA combines three main detection systems in one platform: 3D Ground Imaging, Live Scan, and Gradio Smart. This combination allows users to approach different search situations with different technologies instead of relying on a single detection method.
The device processes digital data and signals and converts the collected information into visual and audible results through its display and notification system.

What Is AJAX GAMMA?
AJAX GAMMA is a professional ground imaging and metal detection system developed by AJAX Detector.
The device is designed for prospectors and field users who need imaging capabilities together with direct scanning and magnetic-field-based detection.
Its three detection systems provide different approaches:
● 3D Ground Imaging System
● Live Scan System
● Gradio Smart System
The manufacturer lists maximum published depths of 30 meters for 3D Ground Imaging, 30 meters for Live Scan, and 10 meters for Gradio Smart. These figures are system-specific published specifications and should not be interpreted as guaranteed field depth under every soil condition.
Three Detection Systems
1. 3D Ground Imaging System
The 3D Ground Imaging system is designed to scan underground layers and create three-dimensional representations of detected targets.
According to AJAX, the system uses four primary scanning sensors to collect data from the ground and generate 3D images.
The resulting visualization can assist the user in studying:
● Target shape
● Target position
● Approximate size
● Underground cavities
● Metals
● Buried treasures
● Historical graves
● Underground structures
The published search depth for this system is up to 30 meters.
2. Live Scan System
The Live Scan system provides real-time visualization and analysis during the scanning process.
It is designed to give immediate visual feedback about detected underground objects.
AJAX describes a color-based visualization system:
● Green: soil and ground structure
● Red: metals
● Blue: voids and caves
The published maximum search depth for Live Scan is 30 meters.
This system can be useful when the user wants to monitor the scanning process continuously rather than relying only on a completed 3D scan.
3. Gradio Smart System
The Gradio Smart system is designed for deep scanning and target confirmation.
It works by analyzing magnetic fields associated with buried metallic objects and is intended to detect both smaller and larger targets.
The published depth for Gradio Smart is up to 10 meters.
The Gradio Smart sensor is designed as a lightweight handheld component, allowing the operator to use it for more localized searching. AJAX lists the sensor dimensions as approximately 55 8 3 cm with a weight of about 270 grams.
What Can AJAX GAMMA Detect?
According to the manufacturer, GAMMA is designed for a broad range of applications, including:
● Gold
● Precious metals
● Other metals
● Buried treasures
● Underground cavities
● Caves
● Mining exploration
● Archaeological research
● Unexploded ordnance
● Pipes
● Wires
The exact detection capability depends on the selected system, target characteristics, ground conditions, and scanning method.
3D Ground Imaging for Underground Targets
One of the main features of GAMMA is its ability to create visual representations of underground targets.
Instead of providing only an audio response, the 3D system processes the collected scanning data and converts it into an image that can be analyzed on the device.
This can help the operator examine the apparent position and structure of an anomaly before deciding whether further investigation is required.
For professional exploration, imaging can be particularly useful because the operator can compare different scans and analyze the surrounding ground rather than relying exclusively on a single signal.
Live Underground Visualization
GAMMA's Live Scan system is designed to provide immediate feedback while scanning.
The color-based display makes it easier to distinguish between different types of detected responses according to the manufacturer's visualization system.
This approach can be useful for searching areas where the operator needs to follow the changes in the ground response continuously.
Display and Controls
AJAX GAMMA uses a 5-inch TFT color LCD with:
● Resolution: 800 480 WVGA
● Color depth: 16-bit
The display is designed to remain usable in different lighting conditions, including bright outdoor environments and darker conditions.
The interface provides access to the detection systems, scanning information, settings, and stored scan data.
Storage Capacity
The detector includes 1 GB of internal storage and can save up to 1,000 scans.
This allows users to retain previous scanning sessions for later review and comparison.
Audio and Vibration Alerts
GAMMA provides high-quality audio feedback, with sound output specified at 32 Kbit/s MP3.
The device also supports configurable sound and tactile notifications, allowing the operator to receive alerts through more than one feedback method.
Bluetooth Connectivity
The system includes 2.4 GHz Bluetooth connectivity.
AJAX lists sensitivity up to -80 dBm, allowing wireless communication with compatible equipment and accessories.
The manufacturer also offers a tablet designed to connect with AJAX devices and display analysis results on a larger screen.
Processor and Signal Processing
GAMMA uses a MIPS 32 processor architecture with an M4K Core operating processor.
The detector's operating principle is based on processing digital data and signals and converting the results into visual and audible information for the operator.
Battery and Operating Time
AJAX GAMMA is powered by a rechargeable battery rated at:
● Voltage: 7.4V
● Capacity: 3300mAh
● Power rating: 400mA
● Typical operating time: 10 hours

Actual operating time can vary depending on the selected system, display usage, wireless connectivity, and other operating conditions.
Languages
The detector supports eight languages:
1. English
2. French
3. Spanish
4. German
5. Russian
6. Arabic
7. Turkish
8. Italian
The availability of Arabic makes the device suitable for Arabic-speaking users and professional teams operating in the Middle East.
PIN Security and Date/Time
GAMMA includes a configurable PIN login restriction, providing an additional access-control feature.
The device also includes a real-time clock that can be configured manually or synchronized through GPS time according to the published technical specifications.
GAMMA for Different Terrains
AJAX markets GAMMA for use across different soil types and terrains.
The manufacturer emphasizes its application in different environments and describes the system as suitable for prospecting across varying ground conditions.
However, soil mineralization, moisture, electromagnetic interference, ground composition, target size, and operator technique can all influence actual detection performance.
