The OKM Delta Ranger features 2 multi-technology systems. They enable long-range detection of all types of precious metal over distances of several kilometers and at depths of up to 18 m. So you can find buried gold and treasure quickly and easily, or detect underground voids and tunnels.
Features and functions of the OKM Delta Ranger
This metal detector from Inventum Detector also detects voids, tunnels and treasure chests underground. Whether you’re a lover of buried treasure or a seasoned searcher, you’ll also find something to your liking. This easy-to-handle gold detector is a state-of-the-art device.
First, here’s a summary of its features:
- – Detection methods: Magnetometer, Scan/thermal flux, 3D scan by bionic/ionic ground flux;
- – Available functions: Tunnel detection, Treasure hunt ;
- – Detectable items: Gold, precious metals, treasure chests, jewelry, voids, tunnels.



A treasure hunt involving several technologies
The OKM Delta Ranger treasure detector is a unique multi-technology detection device that can’t be found anywhere else. This detector will quickly and easily detect gold objects, relics, treasures, tunnels, voids and graves, even in the most difficult-to-access terrain. The device offers 2 modes of operation in a single device:
- – Ionic Stream: OKM’s long-range mode, specially designed for precise detection of long-buried gold. This makes it possible to make interesting finds in the most hidden places.
- – Bionic Stream: OKM’s long-range mode, with detection capabilities to detect freshly hidden gold with high detector sensitivity.
OKM Delta Ranger user features
This is one of a range of detectors from Inventum Detector designed to detect treasure. It enables treasure seekers to take their exploration a step further by offering intuitive features for users:
- A digital compass to help you find your way during the treasure hunt;
- A visual indication of the target for more precise and efficient detection of objects;
- Multilingual operation in 14 languages to suit users from different countries.
These features greatly enhance the experience for researchers. The Delta Ranger is also equipped with a receiving antenna. Thanks to its long range, it can scan a wide variety of terrains. What’s more, the Smartphone application makes it easy to share scan data and analyze it after measurement. This makes treasure hunting even more exciting and immersive.
The OKM Delta Ranger detects gold with precision
The Light version of the OKM Delta Ranger is the perfect equipment for first-time explorers of unknown terrain. Treasure hunters who have no idea where to start detecting will particularly appreciate the quick overview.
Long-range gold prospecting with a Smartphone
The Light version of the Delta Ranger is perfect for treasure seekers who want to find the right places for a successful treasure hunt. Excavating archaeologists will particularly appreciate the large-area view offered by this equipment.
Using the Delta Ranger’s advanced detection capabilities, users can locate different types of metal. Whether it’s a gold nugget or a more common metal object. What’s more, the Delta Ranger features ground radar for searching for targets buried deep underground. This makes it an essential tool for professional treasure hunters.
In short, whether you’re a novice treasure hunter or an experienced archaeologist, the Light version of the Delta Ranger is the ideal device for finding metal objects buried in the ground.

The Bionic Stream (bioenergetic system) in the OKM Delta Ranger
During gold detection, the Bionic Stream, a bioenergetic system, interacts with the detector user’s natural bioenergy to analyze minimal changes in the object’s substances. Thanks to its high-sensitivity frequencies, you’ll be able to locate all gold objects, regardless of how long they’ve been buried. So, if you’re looking for a gold detector that can detect freshly buried objects such as gold jewelry, gold statues, gold rings, gold coins, gold bars and gold bullion, the Bionic Stream is a mid-range detector that could be the perfect choice for you, depending on your budget. And with its compact, lightweight design, you can easily take it with you in a backpack on your treasure-hunting adventures.
Discover also the Ionic Stream feature (Ions-Chamber system)
The Ionic Stream metal detector measures ionic radiation from objects buried in gold. For optimum results, the direction of detection is crucial, and the integrated digital compass provides precise direction indication during measurement.
This detection method is suitable for long-term archaeological investigations to locate gold objects that have been buried for some time. The sensitivity of this type of detector is adjustable to suit different field conditions. So, if you’re looking to find gold objects with a specialized type of detector, Ionic Stream is the right detector for finding buried treasure.
Exceptional long-range performance in Bionic and Ionic Stream
Bionic Stream offers the ability to detect gold in damp environments, on wet ground and even after days of rain, unlike many other long-range detectors which require dry ground. The two long-range modes, Bionic Stream and Ionic Stream, also offer the best performance in sparsely populated areas. Thanks to the high sensitivity of the integrated sensors to changes in the ionic and bionic fields, detection accuracy is considerably improved in undisturbed or undeveloped areas. As a prospector, this means you can locate gold objects at great depths without having to dig large holes or use expensive ground radar.
Gold prospectors and treasure hunters will also appreciate the portability and ease of use of these detectors. They enable the search for buried objects in hard-to-reach or remote locations. Thanks to their simple configuration, prospectors can quickly start exploring the most promising areas without the need for heavy equipment or in-depth technical training.
Gold detection: three feedbacks at the touch of a button
In long-range detection modes, a key is signalled by three types of feedback:
- – A vibration (if the vibration option is enabled) ;
- – Audio feedback (if sound is enabled) ;
- – Visual feedback (crosshairs flash).

Locating and confirming treasures by triangulation (cross-bearing)
The triangulation method (Cross Bearing) involves using two or more points to locate a target. When identical results are obtained for the same target from different positions, it is likely to be a potential target.
