The Ground Scan (G) probe adds two additional operating modes to the Delta Ranger Professional. With the Magnetometer and 3D Ground Scan, users can take accurate and vertical measurements of the subsoil. Inventum Detector supplies the Delta Ranger Professional with the Ground Scan (G) probe, allowing treasure hunters to locate potential targets for their searches. Finding precious metals thus becomes much easier and more enjoyable than with a standard metal or gold detector.

The Delta Ranger Professional is a highly efficient metal detector designed for exploration. Its ready-to-use operating mode is practical and easy to master. Whether for amateurs or professionals, this device enables the detection of all kinds of buried ferrous objects as well as underground cavities.

The Delta Ranger Professional is the detector you need for remarkable discoveries. Our device features a unique and innovative technology that enables 3D imaging-based metal detection. Developed in Germany, the Delta Ranger Professional equipped with the 3D Ground Scan is exceptionally powerful, capable of locating ferrous objects up to 18 meters deep.

Once the measurement is recorded, users can analyze the scan image in detail and determine the exact size, position, and depth of the detected object. All that remains is to dig and retrieve the find.
Thanks to its high sensitivity, the Delta Ranger Professional can detect even the smallest and deepest objects, such as coins. Compact and lightweight, it fits easily into a backpack, making it ideal for all types of fieldwork. Adaptable and powerful, it is the perfect ally for detecting precious metals — especially if it fits your budget.

Choosing the right type of detector makes metal and cavity research faster and more efficient. The Thermo Scan function detects temperature variations on any surface according to a specific pattern.

The OKM Delta Ranger metal detector accurately measures the surface of horizontal walls with the help of its extremely short probe. It can detect hidden chambers and corridors by identifying temperature differences on walls.

Additionally, the detector can also be used vertically (as in the 3D Ground Scan mode) to efficiently detect underground cavities, chambers, and tunnels.

The Delta Ranger Professional, equipped with Thermo Stream mode, uses a live camera image for easy visualization of temperature differences.
The device’s ground radar is a valuable tool for archaeologists — with its thermal imaging technology, users can efficiently detect objects and archaeological structures by analyzing temperature variations.

The Thermo Stream principle is straightforward and ergonomic: it simplifies the visualization of temperature changes by creating a color pattern that identifies hot and cold zones.

• To determine the surface temperature of the targeted object, several display options are available:
• – As a numeric value in Celsius or Fahrenheit,
• – As a color point cloud on the camera image,
• – Indicated by a pointer on the temperature scale.

Thermography typically uses color codes to identify areas with temperature changes, helping to locate buried objects. For instance, blue represents cold and red represents heat.

Scientists often use false-color imaging to enhance subtle nuances. Thus, color combinations are based on artificial spectrums.

The Delta Ranger Professional uses these false-color methods in its Thermo Scan and Thermo Stream modes. The artificial color spectrum — ranging from black (cold) to white (hot), passing through shades of red and violet — makes it much easier to visualize temperature differences.

There is a wide range of detection equipment, each specialized for different types of metals. This particular type of device, designed for the detection of cavities and precious metals, is ideal for archaeological exploration and will meet all your expectations. Easy to use, the Delta Ranger Professional detects metals with high precision and sensitivity, making it a powerful tool for archaeologists and treasure hunters alike.
