Treasure Hunting with Multiple Technologies

The OKM Delta Ranger is a unique detector in our store, offering multi-technology treasure detection capabilities. It excels in quickly and efficiently detecting gold objects, relics, treasures, voids, tunnels, and tombs, even in difficult terrains. The detector combines 6 operating modes in one device:

  1. Bionic Stream – OKM's long-range mode for detecting freshly hidden gold.
  2. Ionic Stream – OKM's long-range mode for detecting gold buried over long periods.
  3. Magnetometer – A fast technology for preparing and optimizing 3D Ground Scans.
  4. 3D Ground Scan – OKM's famous 3D imaging technology, detecting treasures up to 60 ft deep.
  5. Thermo Scan – Thermography mode to map hidden tunnels and rooms.
  6. Thermo Stream – Real-time thermography for detecting hidden caves and tombs.

Delta Ranger's highlights include a digital compass, visual target indication, multi-lingual operation in 14 languages, and control via a Smartphone App for easy sharing and analysis of scan data.

Delta Ranger Knows Where to Find Gold

The Light version of Delta Ranger is perfect for initial explorations to locate successful treasure hunting spots. It is especially useful for treasure hunters uncertain about where to start, providing a quick overview of large areas.

Long-Range Gold Prospection with Smartphone

The Long-Range Probe (L) transforms the OKM Delta Ranger into a long-range gold detector. Its Cross Bearing (Triangulation) feature accurately determines the position of gold objects.

Bionic Stream (Bio-Energy-System)

This mode interacts with the user’s bio-energy to locate gold objects, regardless of how long they have been buried, making it ideal for finding freshly buried items.

Ionic Stream (Ions-Chamber-System)

Ionic Stream measures the ions radiation of long-buried gold objects. The integrated digital compass aids in directional measurements during the search.

Best Long-Range Performance

Both Bionic and Ionic Streams work well in various conditions, including after rain, in humid places, or in sparsely populated areas, where their sensitivity increases.

Detect Gold: Triple Feedback on a Hit

Hits are indicated through acoustic feedback, vibration, and visual feedback (flashy crosshairs).

Treasure Detection and Verification by Cross Bearing (Triangulation)

This technique uses multiple points to accurately locate a target.

Delta Ranger Professional: More Probes, More Treasures

Adding two extra probes turns the Delta Ranger into a Professional detector, suitable for 3D ground scans and deep underground analyses.

Best Depth Performance with 3D Ground Scan

The Ground Scan Probe (G) enables Magnetometer and 3D Ground Scan modes for vertical underground measurements.

Detect Secret Passages and Tunnels with Thermography

Using the Thermo Probe (T) unlocks Thermo Scan and Thermo Stream modes, ideal for detecting underground cavities, chambers, tunnels, and hidden rooms behind walls.

Void and Cave Detection Inspired by Science

The Thermo Scan and Thermo Stream modes use false color schemes for easy differentiation of temperature nuances, essential in scientific applications.
