eXp 6000 – 3D Ground Scanner by OKM Metal Detectors

The eXp 6000 ground scanner is OKM's top of the line 3d metal detector, an ultra-modern geophysical detection instrument to locate buried artifacts, lost treasures, subsurface anomalies, underground utilities as well as other hidden structures. It provides nondestructive examination methods to render graphical images of subterranean targets before excavation.

Based on practical experiences with the ancestors eXp 4500 and eXp 5000, the revolutionary release of the eXp 6000 ground scanner opens up new opportunities for serious treasure hunters, gold seekers, archaeologists, prospectors, ground research companies and metal detecting enthusiasts.

The most important innovations of the eXp 6000 ground scanner are:

  • Totally wireless, all components are communicating by WiFi
  • All measuring probes contain an integrated gyroscope (orientation sensor)
    • New invented, extendable Telescopic Probe (patent pending)
    • Famous Super Sensor, Tunnel Sensor and LiveStream Sensor as known from the well established eXp 4500 and eXp 5000

  • High resolution display (1024 x 768 Pixel) with touch screen capabilities and automatic brightness regulation
  • Multilingual user interface with different layouts/skins to optimize readability under tough light conditions
  • GPS tracking and navigation (can be activated by the user)
  • Connection of wireless Android video eye glasses or Tablet PC's to improve handling or supervising
  • Sound output via internal speaker, standard wired headphones or wireless Bluetooth headphones possible
  • Powered by rechargeable cable-free Power Packs
  • Visualizer 3D software for in-depth analyses of conducted ground scans (easy data transfer via USB stick, no additional driver installation necessary)

The eXp 6000 ground scanner is a perfect detection device with penetration depths high beyond usual metal detectors to locate buried subsurface anomalies. This 3d metal detector can be used for the following tasks and applications:

  • Treasure hunting of buried artifacts and metal items made of gold, silver, copper and bronze
  • Detection of underground non-metal anomalies such as walls, foundations, statues, ancient tombs, caves, sepulchers, chambers and the like
  • Prospecting natural gold minerals
  • Pinpointing valuable artifacts and treasure finds
  • Ground surveying battle fields, historic settlements and ancient sanctuaries

All components of the eXp 6000 including control unit, telescopic rod assembly and measuring probes are completely wireless and will connect to each other via WiFi. The integrated GPS receiver, that can be activated by the user, is able to store GPS coordinates along with the measured values. Thus you can use the GPS navigation features of the eXp 6000 to locate the areas of your recorded scans easily, even after a long time between ground survey and scan analysis.

Measuring Probes

The eXp 6000 metal detector comes with a variety of specialized measuring probes. Each measuring probe is equipped with an orientation sensor (gyroscope) that assists in conducting scan images of high quality. By keeping track of the probe's orientation the operator can immediately correct inclinations of the connected measuring probe while scanning the underground. The user will get a visual indication directly onto the screen or video eye glasses of the eXp 6000 as well as an acoustical signal.

Telescopic Probe

This very new and unique ground scanning probe was invented by OKM to reduce the amount of scanning probes as used with previously eXp detectors. Now the treasure hunter will utilize one single horizontal GPR probe that can be extended from 50 cm to 120 cm scanning width.

Super Sensor

As the name of this measuring probe already implies, the Super Sensor is one of the most versatile ground scanning probe that can be used for additional operating modes like Pin Pointer (with metal discrimination) and Mineral Scan (detection of natural gold occurrences).

LiveStream Sensor

LiveStream Sensor mounted to the eXp 6000 metal detector

Due to its complex sensor design the LiveStream Sensor is operated to get a direct view into the underground. The measuring data will be streamed onto the display or the video eye glasses of the eXp 6000 to locate hidden objects and underground structures. Thus the operator of the metal detector receives quick information regarding what is buried beneath his feet in the underground soil.

Tunnel Sensor

The Tunnel Sensor has been designed to locate underground hollow spaces like tunnels, caves, sepulchers, dugouts, bunkers, shelters, tombs and the like. Thus it can be used to detect non-metallic changes within the subsurface soil.

Operating Modes

The eXp 6000 supports different operating modes that can be used to detect underground treasures, artifacts, facilities and voids. Depending on the operator's task or application the appropriate operating mode has to be used in conjunction with one of the measuring probes.

Ground Scan

Ground Scan, operating mode of the eXp 6000 ground scanner

The Ground Scan operating mode can be considered as the most important function. The operator can use all available measuring probes to create a full ground scan of a scan area. The resulting scan image can be stored into the metal detector's control unit for additional analyses. Simply transfer the data via USB stick to a Windows computer to utilize the Visualizer 3D software for in-depth analysis like position determination, depth and size measurements as well as signal corrections.

Pin Pointer

Pin Pointer, operating mode of the eXp 6000 ground scanner

The Pin Pointer operating mode utilizes the Super Sensor to pinpoint the exact location of detected objects. It also gives some kind of indication concerning the type of metal (ferrous vs. non-ferrous).

Live Scan

Live Scan, operating mode of the eXp 6000 ground scanner

The Live Scan operating mode can be used in conjunction with the LiveStream Sensor only. The detectorist will receive scan information streamed directly onto the screen or video eye glasses of the eXp 6000.

Mineral Scan

Mineral Scan, operating mode of the eXp 6000 ground scanner

For prospectors and gold seekers the Mineral Scan operating mode comes into focus. This function is operated with the Super Sensor to locate underground deposits of natural minerals like gold.

Tunnel Scan

Tunnel Scan, operating mode of the eXp 6000 ground scanner

The Tunnel Scan functionality is intended for all operators who are looking for voids, caves, chambers, tombs, tunnels and the like. This operating mode can only be used with the Tunnel Sensor to highlight potential places of non-metallic objects and anomalies.


Magnetometer, operating mode of the eXp 6000 ground scanner

Operators looking for ferrous metals like iron, iron oxide, stainless steel or alloys of iron with other metals will use the operating mode Magnetometer. This function indicates the presence of ferrous metals in an audio-visual way. Furthermore it can be used to clean ferrous contaminated areas before conducting ground scans for precious non-ferrous metals like gold, silver, copper or bronze.

Wireless Android devices (Glasses and Tablet PC)

Alternatively to the folding display, the operator of the eXp 6000 ground scanner can connect any modern Android Tablet PC or Android video eye glasses by WiFi. This can be necessary to either replace the display or to allow some additional user(s) to watch alongside while the operator is using the detector. Especially the video eye glasses can support your work by bringing the screen information closer to the user's eyes and reduces the light emission of the standard display.

Both alternatives are also very helpful while giving a technical demonstration of the eXp 6000 metal detector or supervising the operator's work.
