It was a sunny day, I went with my equinkx and my Australian Shepherd Sokrat in a field bordering a beautiful valley. Arrived there, I realize that the ground is very mineralized, I tell myself in my head that it is screwed up, I will not find anything because of this mineralization! I decided to test anyway, and to my surprise I found some French and Belgian coins from the 19th century despite this strong mineralization! The equinox was once again the most effective on a very difficult ground! I am impressed with each release of its power!
