I want to share with you the story that happened to me in the forest. I went with my X-TERRA 70 and a 7.5 kHz concentric coil. This is my favorite coil with which I walk and find a lot of coins but also bayonets, a helmet of great depth and many other things. At the edge of the forest, I walked and heard a beautiful tone on colored metal. My detector was not wrong and found Roman fibula and 2 meters further the situation was repeated. Again, a beautiful signal and I could not believe it. Second Roman fibula. Now my imagination has worked really hard. I went and looked further but unfortunately no result. After 3 hours, I decided to go home but happy. On my return, however, I decided to return to this place but already with the 18.75 kHz sniper coil. You will not believe but I found two more parts of fibula there. But that's not all. Great was my joy as Minelab sang and dug a Roman silver denar and in a very short distance 4 silver discs. Now I know that it is worth to use different coils with X-TERRA because they make the detector really effective and professional.
