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.


In november 2005 some of our customers found a wooden chest filled up with gold bars. Those bullions were buried during the World War II by greek guerillas. The treasure hunters and archeologists used different metal detectors and geophysical instruments like the Earth Imager eXp 3000, the predecessor of eXp 4000.


A greek gold prospector, metal detecting with Earth Imager eXp 4000, found several gold coins. He told us about his finding during a visit in our company. He located the treasure in approx. 2 meters depth. These ancient coins are very precious, as confirmed by archeologists.


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 ...


These ancient door beaters has been detected with eXp 4000 in the Middle East area. The beaters, made of pure gold, were used in ancient times on wooden doors. The targets were buried single in the ground and has been located at a depth of 140 cm. The gold rings were dug up without any patina visible on the surface and are well preserved.


A small team of treasure hunters from the US has been made a wonderful discovery on the coast of Suriname. By using the metal detector and treasure hunting detector eXp 4000 they located a lot of glass bottles. Furthermore they discovered a spanish sword as well as silver coins.


One of our customers from Maghreb in North Africa reported about his successful treasure hunt. He was using the 3d metal detector and ground scanner eXp 3000, the predecessor of the earth imager eXp 4000, when he located some anomalies inside the underground. The customer was searching in very uneven ground and therefor he used the 25 cm GPR probe of his geophysical phase reader to obtain accurate detecting results.


A treasure hunter from Greece, who is using eXp 4000, found several ancient coins within an old grave. The treasure contains about 54 coins in three different sizes and motifs. Unfortunately the treasure hunter could not give any details on the age or regional provenance of the coins.


Since 1 year the owner of the OKM ground scanner eXp 4000 from the Balkan area is using his locating equipment with many success. He sent us some photos of his findings. Based on his historic knowledge he explored many interesting sites where possible antique treasures could be located. He scanned these areas with the 3d metal detector eXp 4000 and was able to locate many ancient items.


Once again customers from the Middle East area informed us about new finds with their treasure detector eXp 4000. The precious ancient artifacts has been excavated in Syria. These very special targets were hidden about 1,20 m underground. The measurements in eXp 4000's Ground Scan mode has been confirmed before digging with the DDV system (visual metal detector system with metal discrimination).
