Delta Ranger

Delta Ranger from OKM is an exclusive and unique multi-technologies metal detector

with latest development in metal detection field.

Delta Ranger is an advanced multi-technology treasure detector designed for the swift and effortless

detection of golden objects like jewelry, valuable relics, ancient treasures, voids, tunnels, and tombs in difficult-to-reach terrains.

The device incorporates six different operation modes into a single unit and user can change between

them easily by installing suitable probe, and therefore the treasure hunters can use it for different applications.

In addition, the Delta Ranger has several other features that cater to the needs of treasure hunters, such as a digital compass

, visual target indication, and multi-lingual operation in 14 different languages.

These features enhance the treasure hunting experience significantly.

Moreover, the user can control the device by a smartphone app, making it easy to share and analyze scan

data in ground scan mode after measurements.

Delta Ranger Device Features

Applications & Uses

– Detection of either recently buried or long-time buried golden objects such as jewelry (rings – necklaces- bracelets)

– Deep treasure detection like treasure chests, statues, vessels and so on

– Cavities detection including for example: tunnels – tombs – caves

Delta Ranger Editions

The device comes in two different editions with different set of probes and operating modes in each edition:

Delta Ranger Light

The Delta Ranger Light edition is an ideal piece of equipment for conducting preliminary explorations

of uncharted territories to locate potential spots for successful treasure hunting.

Treasure hunters who lack information about where to begin detecting will particularly value the device’s

ability to provide a quick overview of vast areas.

Included Probes:

Long-Range Probe (L) only.

Operating Modes:

Ionic Stream – Bionic Stream

Delta Ranger Professional

By incorporating two additional probes, the Delta Ranger transforms into a professional-grade multi-systems

detector that offers long-range metal detection, as well as 3D ground scans and subsurface analyses with thermal systems.

Included Probes:

Long-Range Probe (L) – Thermo Probe (T) – Ground Scan Probe (G)

Operating Modes:

Ionic Stream – Bionic Stream – Magnetometer

3D Ground Scan – Thermo Scan – Thermo Stream

Operating Modes

Delta Ranger device operating modes consists of six diverse modes, which can be conveniently

switched between by installing the appropriate probe.

These modes enables treasure hunters to utilize the device for various metal detection tasks,

thereby making it a versatile tool for all their professional needs.

Long-Range Modes (Light & Professional Edition)

The OKM Delta Ranger device can function as a long-range metal and gold detector by employing

the Long-Range probe, which is capable of detecting buried objects at distances spanning several miles.

To determine the precise location of gold objects, Cross Bearing (Triangulation) is used.

Triangulation (Cross Bearing) uses two or more points to locate a target. As soon as user hits on the same target

spot from different positions, it is likely it is a potential target.


In the long-range modes, the device offer triple feedback:

– Acoustic feedback via speaker.

– Visual feedback on smartphone app (flashy crosshairs).

– Vibration if enabled

Ionic Stream (Ions-Chamber-System)

The Ionic Stream operating mode utilizes the ions radiation (ions absorbent)

of buried gold or metallic objects to locate them accurately.

Therefore, the direction in which the device is pointing during the measurement

is crucial for achieving correct and accurate results.

Fortunately, the device comes equipped with an integrated digital compass

that displays the direction during the measurement process.

This detection method designed specifically for locating old gold artifacts

that have been buried for a long period.

As a rule: the longer the object remains underground, it will be easier

and more efficient to detect it using the Ionic Stream operating mode.

Bionic Stream (Bio-Energy-System)

When detecting gold, the Bionic Stream mode uses the natural bio-energy of the device

user to analyze even the slightest changes in object substances.

This innovative technology allows gold prospectors and treasure hunters to locate

nearly all gold objects, regardless of how long they have been buried

underground. Therefore, the Bionic Stream mode is particularly suitable for detecting

recently buried gold items, such as golden jewelry, golden statues,

gold rings, golden coins, golden bars, and gold bullions.

3D Ground Scan [Professional Edition Only]

OKM is a well-known company that has gained recognition for its exceptional technology

in 3D imaging detection, designed and produced in Germany.

The technology employed by OKM is capable of detecting objects that are buried deep

in the ground, as far down as 60 feet or 18 meters, making it

one of the most efficient operating modes available for this purpose.

The 3D Ground Scan operating mode is particularly efficient for locating target objects.

After completing the scanning process, the results saved

for later analysis on bundled Notebook with Visualizer 3D Studio software.

3d ground scan

This feature is especially useful for treasure hunters as it allows them to inspect and analyze the image of the scan in detail. By doing so,

they can determine the precise position of the targets, their size, and the depth at which they are buried.

Using the analysis of the scan image, treasure hunters can make a more informed decision about the excavation process.

This not only saves time but also increases the chances of a successful outcome.

The technology employed by OKM is not only efficient but also reliable,

making it an ideal choice for those who are passionate about treasure hunting.

Magnetometer [Professional Edition Only]

It is advisable to utilize this pre-configured operating mode

before conducting the 3D Ground Scan to ensure the scan field is adequately prepared

and free from any ferrous materials that situated close to the surface.

The benefit of this preparation is that it enables the detection of buried

objects that are deeper in the ground, with even greater accuracy

during the subsequent 3D Ground Scan.


Thermo Scan [Professional Edition Only]

The Thermo Scan feature allows detection of temperature differences over larger surfaces,

using a specific measurement scheme similar to the 3D Ground Scan mode.

The OKM Delta Ranger’s Thermo probe is perfect for measuring temperature differences

on horizontal wall surfaces, revealing hidden rooms and corridors.

Moreover, the user can use the detector vertically, akin to the 3D Ground Scan mode,

to identify underground cavities, chambers, and tunnels.

Thermo Stream [Professional Edition Only]

By utilizing the Thermo Stream operating mode, what is called a false color scheme used to simplify

the visualization of temperature differences while using the live camera image from bundled Android

smart phone as a background inside OKM app.

With proper crosshair calibration prior to measurement, it becomes possible to determine the

surface temperature of specific objects and surfaces at particular points more accurately.

User can indicate the surface temperature of the targeted object in various ways, including

as a simplified color point cloud on the camera image, a pointer on the temperature scale,

or a numerical value in either Celsius or Fahrenheit.
