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.
