Treasure Hunting with Multiple Technologies

Detectors like the OKM Delta Ranger can't be found in any other store! This multi-technology treasure detector is specialized in the fast and easy detection of gold objects, relics, treasures, voids, tunnels, and tombs in terrains that are hard to access. The detector comprises 6 operating modes in one device:

1. Bionic Stream – OKM's long-range mode to detect freshly hidden gold.
2. Ionic Stream – OKM's long-range mode to detect long-time buried gold.
3. Magnetometer – OKM's fast detection technology for the preparation and optimization of 3D Ground Scans.
4. 3D Ground Scan – OKM's renowned 3D imaging technology detecting treasures down to 60 ft (18 m) depth.
5. Thermo Scan – OKM's thermography mode to map hidden tunnels and rooms behind walls and in the underground.
6. Thermo Stream – OKM's real-time thermography mode to detect hidden caves and tombs behind walls and in the underground.

Moreover, Delta Ranger comes with more highlights that take treasure hunters further, and offers user-oriented features like

• Digital compass
• Visual target indication
• Multi-lingual operation in 14 languages

that enhance the treasure hunting experience. Control by Smartphone App simplifies sharing and analyzing scan data after measurements.

Delta Ranger Knows Where to Find Gold

---

The Light version of the Delta Ranger is the perfect equipment for initial explorations of unknown terrain to find places for successful treasure hunting. Especially treasure hunters who don’t have any clue where to start detecting will appreciate the fast overview of large areas.

Best Long-Range Performance in Bionic and Ionic Stream

Bionic Stream allows to search for gold in humid places, on wet soils and even after rainy days. This operating mode does not require dry grounds like many other long-range detectors.

Moreover, both long-range modes, Bionic Stream and Ionic Stream, achieve best performances in sparsely populated areas. Since the integrated sensors are very sensitive to changes of the ionic and bionic fields, the accuracy increases greatly in undisturbed or undeveloped areas.

Void and Cave Detection Inspired by Science

Thermography usually uses color associations for products in everyday use, such as those familiar from a thermostat or tap: blue is associated with cold, while red is perceived as warm.

In science, so-called false color schemes (or pseudo color schemes) are preferred. The false color representation uses colors that deviate from the natural color impression in order to make fine nuances of a tone more easily distinguishable.

The Thermo Scan and Thermo Stream modes rely on this advantage and therefore use the false color spectrum: from black (cold) via blue, purple, red, and yellow to white (warm).
