I decided to try the Silver mode on my CTX 3030 without modifying anything, I wanted to know how effective it was in an area that although it was not very contaminated with iron was quite mineralized, I heard the sound signal first, so I decided to investigate further. You cannot believe when you can get this incredible coin at 35 cm deep (about 13.5 inches). I just could not believe it, I had passed a thousand times through that place with other detectors and I thought that place was totally clean. The surprise was double... On one hand, a spectacular coin and on the other, knowing that I could achieve finds I had not seen before.
