This is part 5 of a series of 7 video tutorials about the geoelectrical water and cavity detector GeoSeeker from OKM. Even after watching this video instructions, we encourage you to read the user's manual as well.


A field test about the 'Rover UC' metal detector and 3d ground scanner written by Andy Sabisch in the 'Lost Treasure' magazine.


In 2013 a small team of OKM members traveled to Tanzania in Africa to demonstrate the gold prospecting capabilities of the Black Hawk metal detector and the 3d ground scanner Rover C II. After a gold mining conference in Mwanza, the gold prospectors themselves used the opportunity to practically test the gold detectors on location. Thus gold nuggets were detected with ease and proof was given that our OKM metal detectors Black Hawk and Rover C II can detect gold deposits with ease effectively.


On June 14th, 2006 Dr. Karl-Heinz Walker, an independent, publicly certified and sworn expert of the IHK Karlsruhe (IHK = Chamber of Industry and Commerce), verified the functionality and reliability of our metal detectors and 3d ground scanners. The field tests have been conducted by utilizing the Future 2005 as well as the eXp 4000 to check if OKM's Geophysical Phase Reader (GPR) technology can detect underground objects under several environmental conditions. The field tests involved detecting gold bars, tunnels as well as non-ferrous metals at different depths.

Introduction and Field Test about the Grailfinder in the French treasure hunting magazine "Le Prospecteur".


Geophysical investigations with the metal detectors Future I-160 and eXp 4000 over an unimpressive field in Belgium unearthed astonishing discoveries. For 90 years it was hidden deep under the surface of the Belgium ground but now the underground bunker system is explored by british scientists. This is the start of an exciting time travel back into the time of World War I ...


On a sunny day some colleagues from OKM grabbed a Black Hawk pulse induction metal detector and started treasure hunting in a nearby wooden area with some old houses. During our search we found several buried items and artifacts. Mostly some old coins were detected but also some other objects the people lost over the past years. This was also a good opportunity for OKM to get new ideas for further improving the Black Hawk metal detector. This day we cleared the area close to the earth's surface but we will come back with our 3d ground scanners eXp 4500 and eXp 6000 to find the deep hidden treasures too.
